Final Project: Design and Simulation of a Loudspeaker-Due 5/12 @11A
代写声学 process clean/dry audio with the microphone model (e.g., at different simulated distances to capture proximity effect).
Introduction
For this project, you will be asked to design and simulate a loudspeaker (or microphone) as an Application Note
Design phase (50% of grade) 代写声学
- This section of the application note will describe the specific marketing need and/or intended use case. Based on the application needs, include the sections:
- Introduction
- Loudspeaker Intended Applicationand Design Choices
- Predicted loudspeaker performance: Resonant Gain and Frequency, DC and Peak Impedance, Pressure Sensitivity (SPL), LF and HF cut-offs
- Select a driver that will be used throughout the rest of this project.
- Try to select a driver that has the Thiele-Small parameters well described in the manufacturer’s specification sheet
- A good place to start is: https://www.parts-express.com/cat/speaker-components/4
- Include the driver selection and T-S parameters
- Include a rationale for the selection of this driver
- Any loudspeaker design software or tool may be used, but I highly recommend WinISD made by LinearTeam
- See: http://www.linearteam.org/
Analysis phase (50% of grade)
- This will be assessed with a 5-minute presentation (e.g., PPT) of your findings.
- Matlab simulation and comprehensive analysis
- Write a Matlab program that accepts T-S parameters and simulates the performance of the loudspeaker
- The Matlab program should be an interface that accepts any T-S parameter(s),
- The program should calculate unknown parameters (when possible)
- The output must include (at least):
- High-Frequency roll-off,
- indicate first-mode of driver break-up,
- loudspeaker sensitivity,
- loudspeaker efficiency,
- output acoustic power,
- any low-end resonances (frequency, gain, Q)
Alternatives 代写声学
In lieu of a loudspeaker design/simulation, a microphone design/simulation may be substituted in. You could consider: MEMS designs; on/off axis responses; simulate covering the entry holes for cardioid mics; process clean/dry audio with the microphone model (e.g., at different simulated distances to capture proximity effect).
