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).
