Dome Tweeter with Composite Diaphragm — Frequency-Domain Response
Application ID: 126681
Loudspeaker design is a challenging task. The objective is to achieve high sound quality while satisfying manufacturing and operational constraints. Sound quality depends on many factors, including the ability to control, damp, and shift diaphragm resonances and to control diaphragm breakup.
In this example, the frequency responses of a dome tweeter with different diaphragm materials are compared. Composite diaphragm materials produce a smoother frequency response than conventional materials such as titanium. The ability of composites to break symmetries in the mode shapes and shift resonances can improve the frequency response of a dome tweeter.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- Module Acoustics et
- Module Composite Materials et
- soit le Module MEMS, ou Module Structural Mechanics et
- soit le Module AC/DC, Module Battery Design, Module Electric Discharge, Module MEMS, Module Plasma, Module RF, ou Module Semiconductor
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
