1 TOOT HILL DESIGN TECHNOLOGY DEPARTMENT YR 9 MP3 SPEAKER In this project you will learn: Reserch Skills. Health and Safety Basic electronics Soldering skills Quality Control Generating ideas Research

2 Page 2 DESIGN BRIEF TASK 1: Copy out and complete the Design Brief in your exercise book. Remember to underline your headings. Brief: You are to design and manufacture an MP3 amp circuit and design a prototype for the packaging (case) of the electronic circuitry and components. TASK 2: Spider Diagram of ideas. Write down as many different ideas as you can for the shape and style of the packaging (case). Remember you can base your idea on anything! I DOG SPEAKER! TASK 3: Using the internet find 3 different types of MP3 speakers. Copy and paste the pictures into word and below each picture produce a table and write about the following items. Materials Ergonomics Aesthetics Cost Comments Marks out of 10

3 Page 3 PRODUCT ANALYSIS TASK 4 : Having completed your Product Analysis explain in your own words which MP3 speaker system you would buy out of the three and explain the reason for your choice. Use the following words in your paragraph: Materials Ergonomics Aesthetics Cost LITERACY! TASK 5: Questionnaire A questionnaire is used to find out the opinions and ideas of others. It is a research tool which is used in industry. In your exercise books write the definition for each of the following words. You may find it easy to present it in a table? Materials Cost Function Aesthetics Reliability Target Group Ergonomics Safety DEFINITION

4 Page 4 QUESTIONNAIRE AND RESULTS TASK 6: In your exercise books produce a questionnaire including 8 questions. Each Question must be based on the words form the previous task. Remember in a questionnaire ensure to write questions where there are several answers to choose from E.g., Materials If you were to buy an MP3 speaker which of the following materials would you prefer it to be made from? Steel Aluminium Plastic Wood Task 7: When you have completed your questionnaire type it in Word and print out 3 copies. Then get 3 people to complete a questionnaire each. Record their answers and use EXCEL to produce Pie Charts or Bar Charts. Your teacher will teach you how to use the software. ICT!

5 Page 5 SPECIFICATION TASK 8: Now you have a completed your research use the information gathered to write a specification for your MP3 player. Remember a specification is a series of statements describing what your final product MUST or MAY have. Use the words from Task 5 to help produce your Specification. You may wish to present it in table like below: It MUST be... It MAY have... Materials Cost Function Aesthetics Reliability Target Group Ergonomics Safety

6 Page 6 DESIGN IDEAS TASK 9: In your exercise books draw 4 different designs for a possible MP3 speaker. Annotate your designs referring to your specification as much as you can. Remember to look at the Assessment for Learning posters in your classroom. Include colour on your designs. SOLDERING TASK 10: On A3 paper draw a picture of the following tools used for soldering and write their correct name in a table in your exercise books. Draw Picture Tools name Use? Soldering Iron Soldering Iron Stand Solder Solder Sucker Printed Circuit Board Side cutters Transistor Resistor Capacitor Speaker Battery Clip Intergraded circuit Chip Holder Jack

7 Page 7 SOLDERING Task 11: Write the following sentences in your exercise book in the correct order of sequence. Clamp the PCB to the table (or stick down with Masking tape) and heat the leg of the component with the soldering iron... Add solder to the joint whilst the soldering iron is still in contact with the component leg. Bend the legs on the component so they can fit into the PCB. Gather tools - Soldering Iron. Soldering Iron Stand, Solder, Side cutters, Sponge. Ask your teacher to check the joint then trim with the side cutters. Place the components into the PCB ensuring you put it in in the correct way up.

8 Page 8 SOLDERING Task 12 : Using the powerpoint on soldering follow the instructions and build your circuit for the MP3 speaker. Remember to check your component values and make sure your joints are not dry. You need to build small volcanoes! See diagram below. Task 13: Once you have completed your circuit you need to check your circuit to see if it works! Connect your circuit to a 9 V battery and plug it into your MP3 player. Not working?- Check the following! Dry Joints! - Might be holes visible in the joint Capacitors in the PCB in the correct position Chip Holder soldered incorrectly. Check position! Resistors in the wrong position on the PCB Loose connection on your multi core wires.

9 Page 9 LASER CUTTER () Task 14:Once you have completed your circuit you need to use the Laser Cutter to cut out the housing for the Amp circuit. Your teacher will give you a demo on how to use it. Before using the Laser Cutter study the following photographs and answer the questions on the next page. / Software + Laser Cutter Honeycomb cutting bed Inside the Laser cutter. Material is placed in top the left corner. This is called Computer Aided Manufacture Materials that can be cut on the laser cutter: Acrylic (3mm), Paper, Card, Textiles, MDF

10 Page 10 Techsoft 2-D Design : The image on the left is a screen print of the software used to design the casing for the electronics. Once this is completed it is sent to the laser cutter. The software is very easy to use. This is called Computer Aided Design This tool bar is used to create basic shapes, insert text, add labels and apply colours to images. This tool bar is used to change the drawing point on the screen. You are also able to magnify in and out on the screen. There are also delete options available.

11 Page 11 / Task 14:Draw the table below in your exercise book. (Be sure to use a pencil and ruler) Write down as many advantages and disadvantages as you can for using / when manufacturing any product in industry? ADVANTAGES DISADVANTAGES

12 Evaluation Page 12 Task 16: Complete the evaluation in your exercise books 8. I behaved appropriately and responded promptly to teacher instruction. 1. I worked to deadlines in class and with my homework. 2. I have successfully soldered my circuit together 5 7. I carefully followed Health & Safety rules at all times I produced a quality marketable product. 6. I have enjoyed the year project 5. I have tried to ensure that my written work is presented appropriately and neatly. 4. I have tried to raise the standard of my achievement. 3 things I have learnt which I can use in my next module: 3 things I need to improve in the next module: Include a photograph of your final product in your exercise book with your evaluation
