2. The Company
‘The company was founded in 1961 by Raymond Cooke OBE
(1925–1995) and was initially headquartered in a Nissen Hut
on the premises of Kent Engineering & Foundry (from where
the name KEF is derived) – a metal-working company on the
banks of the River Medway, near Maidstone in Kent. Cooke,
an ex-BBC Electrical Engineer, was keen to experiment with
new materials and technologies in order to create products
with superior acoustic quality that could reproduce
recordings as natural as the original performance. From the
very beginning, the pioneering inventiveness of KEF

4. Technology:
KEF has developed new technology which is
improving both the quality and functionality of
their product making their products unique.
The Uni-Q point source drive array gives
‘outstanding acoustical clarity and off axis

better sound quality.
5. Task Analysis
Function: Multiple speakers could be used for increased sound quality. The portability of the
speakers also needs to be taken into account. The speaker could have iPod/ smart phone
docking capabilities which is becoming ever more popular allowing for more ergonomic control
(touch screen on smart phones). Another important focus is what type of speaker it will be e.g.
docking station, headphone, Wi-Fi or surround sound. Linked also with functionality is what Through task analysis

more unusual material or sourced locally for a higher quality.
Technology: The speakers could incorporate several KEF technology such as ACE or
Uni- Q to optimise the sound quality of the audio product.
Size and environment:
Were will the speaker be used? How big will the speaker be? Will the audio product be
in the form of headphones or a stereo system? Environment and size are closely linked.
For example when designing a bedroom speaker it needs to be of reasonable size to
produce enough sound but not too big to take up too much space.
Manufacture: The audio product can be made in several mays. The processes are
dependant on the materials being used for example when using metals a forging
method will be used however forming will be used for plastics. Mass production, batch
production and one off production are all manufacturing method that need it be taken
into consideration however KEF often stays with batch production.
Energy: The speaker can be powered is many different
ways these include: Solar energy, batteries, mains power
and manual power.

7. Brief
I am going to make a speaker that has both organic
aesthetics and a high quality of sound. The speaker
will have a organic approach and will use
interesting colours and shapes to make my speaker
both innovative and eye-catching to KEF’s high end
buyers. The speaker will be designed for inside use
and will be a small multiple cone speaker. The
speaker will include several speakers with a similar
vibration technology as KEF’s blade speaker. The
target audience will be high end purchasers
interested in spending more money for a high
quality product. The age group of my product will be
broad and appeal to all ages. The speaker will be a
small compact but powerful unit, similar to KEF’s
LS50 and will incorporate new technologies
optimising its performance.
From this page I have gained a greater
understanding of what the objectives of
my speaker are and what I will do to with
it to achieve them.

9. Target Market
My target market will be influenced by KEF.
KEF speakers offer the highest quality of sound
there is. New technological advancements
made by KEF have allowed there product to far
exceed others. However to install these
technologies will come at a price. KEF’s target

draws in customers with more money who are
willing to pay for the best in innovative and
modern sound systems. My target market will
be people aged 20+ which I feel is the optimum
age group in which to attract people who can
afford to by a high quality speaker.
Through analysing my target market
I have understood KEF’s target
market in greater detail which will
prove vital as I will be designing a
speaker for KEF which will have a
heavy influence on my design. I have
chosen to use the same target market
as KEF, the high end market.
10. LINKSFX
Logical:
Audio products can have various logical uses. The primary objective of a audio product is the sound it creates. These audio products can be
in the form of speakers, surround sound, TV speakers, amplifiers for musical instruments, iPod docks and much more.
Illogical:
The are many ways in which audio products can be used in illogical ways. One is that with flat faced speakers people use them to stand
things on which is an illogical use as it may effect sound quality and the speaker is not designed to hold the strain. Another illogical use is
when people have several audio appliances which provide the same function. People often sit and stand on instrumental amplifiers which
can damage the amp. The environment in which the audio product is put into is vital. Often people put there speakers on the ground which
is illogical as carpets take most of the sound and the sound is not directed at the hearer. Despite the primary function of a audio product
being for its sound, people often buy the product just based on its aesthetics. Wires are also illogical as they take up space, do not look
aesthetically pleasing and can be unsafe. Some people choose to have/ design very large speakers which may have good functionality
however the space they take up is unpractical.
Need:
The audio product must be able to produce sound. The audio product must also have a power source that is sustainable as well as being
safe to use in normal use.
Keep:
Energy supplied through mains electricity (wires). New technologies will be incorporated into my design as well as innovative, aesthetically
pleasing shapes. The speaker will be a suspended speaker. The speaker will incorporate several speakers.
Scrap: The standard cuboid shape of many audio products currently on sale. Visible cables will be covered to improve aesthetics and to
avoid a tripping hazard. Also I would like to use a greater variety of colour and scrap the standard dull colours used on many current
products.
From vs. Function:
I will try to keep my product as balanced as possible. A similar technique has been adopted by KEF as they have made their product both
functional and organic. I feel that both function and form are equally important when designing a product , especially for KEF who are
renowned for both aspects.
X-factor:
My audio product will be different from other audio products as it will use unusual shapes with unusual materials choices. The speaker will
include the latest in KEF technology which will make it a unique, interesting and investable product.
11. Primary and secondary

12. Mood Customer Profiling
Board
My product will be heavily influenced by the target audience I
am aiming at. Understanding my customer is vital, and will
help me make important decisions around issues such as
price, aesthetics, and function.
Customers interested in buying my product will be interested
in buying the highest quality speaker possible and will be
willing to spend a reasonable amount of money to get it. I will
be aiming my product at the high end market. I will use high
quality materials and new technologies to optimise
performance and give the customer a functional and
aesthetically pleasing speaker which represents them. My
speaker will be designed to fit into many different
environments which are suited to the customer.
From this mood board I can see that I want to have an organic
approach to my design. I want my speaker to be unique and
multifunctional like some of the speakers I have shown. In the
mood board I have also shown some pictures of things relating
to the design ideas I have which are related to my chosen
environment.

19. Product disassembly
This is the Ted Baker speaker I dissembled for my product disassembly. As you can see from the 2 images above the speakers
fold outwards into two halves each with a speaker compartment. They are allowed to do so by the hinge shows in the right most
photo. The sound is able to spread out by this method and the noise can be changed depending on how far open the speaker is.
The speaker can rest open due to the flat edge of the base of the speaker shown in the middle right photo. An inlay has been
made to host the cable which connects to an mp3 player or iPod. On the frontal face small holes (probably laser cut) have been
cut to allow the sound to pass through.
Here you can see the first stage of the disassembly. The backs of the speaker were held on to the front plates by 3 screws. After
unscrewing these the back plates came off leaving the magnet, the diaphragm and the copper wiring on show. This is shown in the
central photo. These components were hold on to the frontal face by screws and a resin which was very strong. After removing the
screws and resin I was able to look at the front of the speaker shown in the far right photo.

22. Further specification
Function:
• The sound systems must be in keeping with the quality of the products currently available from KEF and the product
must have new technologies.
• The product must include innovative features and technologies to improve on the functionality of the product which in
turn will help in making the product unique in a highly competitive market.
• The speakers must be powered using batteries for extra portability and will have iPod docking capabilities.
• The speakers will be primarily used for music. Due to this I will be using several speakers in my design each of high
quality to provide the best possible sound quality for any genre of music.
• The speaker will incorporate acoustical technologies to enhance sound quality.
• The speaker must be either wall mounted or hung to reduce space occupancy similar to the secondary product I evaluated.
Aesthetics/ materials:
• Must be both organic in shape using natural colours
• The aesthetics must keep in with products currently being produced by KEF.
• Top of the range materials should be used to show the quality of the product as well as improving its functionality.
• I will use a minimalistic colour scheme using bright colours to make my product different but still in keeping with current
KEF products.
Environment:
• The speaker will be designed for inside use.
• The speaker will be of sensible size so that it does not look odd or take up too much space.
• My design will be diverse and will fit into any inside environment especially bedrooms and living rooms without looking
out of place.
Cost:
• The audio product I will create must fit in with the price range of current KEF product. Using state of the art technology and
materials I hope to create a product around the £100 mark for high quality at a reasonable price.
• I will price my speaker at a lower price due to my questionnaire result and it will now cost between £20-80.
Safety:
• Needs to be taken into consideration to ensure that all electrical components are safe to the user and its environment.
• I will try to keep small components to a minimum to reduce the chances of chocking hazards with young children.
• The materials I will use will not be shatterproof and will be easily machined to remove sharp edges.

In my research I have done a several pieces of primary and secondary research. The primary research which I have carried out has
been a questionnaire, a product disassemble, an existing design analysis, Product interaction and an environmental snapshot. Each
has provided me with key finding that will help me in the design of my speaker. My secondary research has also helped me greatly.
The secondary research I have carried out is a mood board, customer profiling, ACESS FM of secondary product and cultural
research.
What I found out and am carrying forward
Questionnaire:
The questionnaire has helped me to gage a suitable price range between £10-80 for my product as well as a suitable environment to put the
speaker in and the best style to go for which from my result is organic.
Product disassembly:
This has helped me to find out exactly what procedures have been put in place to make sure the speaker is secure and safe for use and has
taught me how a speaker is held together.
Product interaction:
Through looking at a product first hand and witnessing its features and how it feels I now know what makes a audio product user friendly
which will help me to incorporate similar features into my design.
Existing design analysis:
This section has helped me to decide what features I should include within my design and how they will effect the speakers usability. I have
decided to incorporate a form of acoustical amplifier within my design to enhance sound quality.
Environmental snapshot:
Through looking at the environment around the speaker it has helped me to see what logical and illogical uses I use my speaker for. With this
in mind I will design a speaker which enhances the logical features and tries to deter those illogical uses which may damage the speaker.
Mood board , Customer profiling and cultural research:
These secondary research techniques have helped me create an image of the audience I am aiming my product at which will help me
dramatically when designing my speaker. I now know that my target market is higher class people who use their products on a regular basis
who live in urban areas and are willing to pay a decant amount of money for a high quality, durable speaker.
ACESS FM of secondary product:
Looking at another product across the ACESS FM range has helped me to understand why a speaker is designed I the way it is to meet the
needs of all of the aspects. I now have a greater understand of what makes a good speaker and have decided to incorporate the hanging
speaker idea into my design.

33. Development
The design that I have chosen to use for my audio product is shown
above. The design incorporates a range of materials, shapes and
aesthetics which epitomizes an organic, natural design. The design
is wall mountable and has been influenced by the shape of a firefly
which fits my brief of creating a nature based design.
The back of my design, that will be attached to the wall, will be made of a green
transparent plastic. I will use techsoft 2D design to create a template which will be sent
to a laser cutter to be cut out. The template will be etched to form the leaf like structure
which is intended to add to the organic nature of my design. The back face will have
Magnets incorporated, held in place by resin so that the speaker can be mounted onto
any wall that has a magnetic dock.
The housing of the speaker will be located at the base of
the design. The base will be made of oak and will
incorporate all of the controls including the volume and
power switch. I will create the oak base using multiple
layers of oak sheet held together using PVA glue. Using a
milling machine, the base will be hollowed for the speaker
housing.
34. Aluminium Aluminium is a silvery white metal made of bauxite. When mixed with
other elements aluminium alloys can be created with several good
properties:
It doesn’t corrode- due to passivation(aluminium oxide layer)
Useful for if the speaker is in damp conditions (Bathroom/ kitchen)
Has a low density making it lightweight.
Good for the speakers portability as well as reducing the force put onto the
magnets holding the speaker to the wall and to the pop rivets holding the wings
in place.
It is soft, ductile and malleable
Meaning that the wings can be easily cold forged into shape around an MDF
mould.
It is durable
Meaning the speaker will have longevity and the constant pivot of the wings
will not damage the wings.
Easily joined
Aluminium can be joined using all the normal methods available such as
welding, soldering, adhesive bonding and riveting.
Non-toxic
Aluminium is not poisonous and is therefore highly suitable for the preparation
and storage of food.
35. Here is an illustration of how the base of my design will be
made up of several layers of MDF stuck together using
PVA. I will then clamp the template into position while it
dries. I will use sandpaper to smooth and round the edges
once the glue has set. Then using an electric drill I will cut
out the grooves in which the metal threads for the wings
can be put into.
An illustration of how the wing template will
be made is shown to the left. I will sand the
shape down until smooth to create an
organic/ ergonomic shape then cold forge
the aluminium around it.
36. LED’s
The base of my design will incorporate
LED’s. These will help with both the
aesthetics and usability of my design.
Aesthetically it will help to make the
design more similar to a fire fly as well
as this the light will make the speaker
much more usable in low light
conditions.
To make my speaker capable to play music I have
decided to include a docking station in my design. You
can connect any device that has a 3.5mm audio jack to
The Dock the speaker. This includes the Apple iPhone / iPad /
iPod, any other MP3 Player.
The speaker I will be using
in my design is a 4”

a very good sound quality,

space, looking out of place
or using up too much
energy.

38. Specification checkpoint
The design I have created is highly functional. So far in my development I have shown how LEDs
could be incorporated into my design for use in the dark which also improves on the aesthetics and
the idea of a firefly. I have also shown were the dock of my speaker will be situated. The speaker is
also portable and can be mounted anywhere in the house using a set of magnets which is what I
said it needed from my initial specification. The wings also help to add to the acoustics of my
design as they are adjustable to allow different measures of sound to escape.
The materials I will be using in my design include aluminium for the wings, transparent
acrylic for the back and an oak base to house the speakers. These materials replicate
the high quality that KEF uses in its products. I have also altered the aesthesis of the
design to make it look more organic and bug like. The design uses simple organic
colours such as green as well as natural materials such as oak.
The speaker is designed for inside use and can be placed around the
house using magnets. The speaker is wall mounted and takes up
little living space which is the main motivation in it being wall
mounted. The speaker will not look out of place due to its natural,
subtle, transparent colours which will help to incorporate the speaker
into its surroundings.
The safety of my design has been
considered throughout my development
and there are now no safety issues. There
are no small components which can be
swallowed nor any sharp edges which
could be hazardous to the user especially
at head height.

41. Anthropometrics and Ergonomics
On this page I will consider how my design
could be developed to be more ergonomic and
anthropometric.
The volume buttons of my design will have a
2cm diameter. I have chosen to develop this to
give make the buttons more user friendly
through the use of anthropometrics.
I have also made adjustments to the width of
the speaker making it proportional to hand, so
that it can be easily picked up and placed
around the house. The base will be curved and
will have a plastic panel on the front making it
more portable and easier to grip.
The speaker will be mounted two meters
above floor level to ensure maximum comfort
and ease of use when altering controls such as
volume.
43. Front Plate
The front plate and rim of my design will be made out of mirrored
plastic. Both will be cut on a laser cutter and will be held on by self
tapping screws. An indent will be made in the oak and then the screws
will be ‘threaded’ into the wood using a Philips screwdriver.
The speaker will fit into the
oak housing and will be held
in place by the plastic rim.

47. Magnets
The plastic back plate of my speaker will
incorporate 3 magnets which will allow my
speaker to be mounted to a wall. Inserts for
the magnets will be drilled 0.5cm and the
magnets will be glued in place with araldite.
The plastic back plate will be held on by 10
self tapping screws. The holes will be cut by
a laser cutter and indents will be will be
drilled into the wooden base so that it will be
easier to thread the crews in. The reason for
using self tapping screws is that they
provided a very strong grip due to the thread
they create which is essential as the speaker
needs to be strong at this point to hold the
speaker firmly onto the wall.
