Abstract
Techniques described herein generally relate to generating an audio signal with a speaker. In some examples, a speaker device is described that includes a membrane and a shutter and driver device is configured to receive an audio signal, modulate it and generate electric signals to operate the speaker and generate an acoustic audio signal.
Claims13
A speaker device comprising:
- a first acoustic medium;
- a second acoustic medium;
- a substrate in contact with the acoustic medium;
- a liner disposed on the substrate;
- and
- a MEMS speaker unit attached directly to the liner, wherein a volume defined between the MEMS speaker unit, the liner and the substrate, includes a first port providing acoustic coupling between the MEMS speaker unit and the first acoustic medium,
- a lid connected to the substrate and covering the MEMS speaker unit and in contact with at least a second acoustic volume;
- wherein the lid includes a second port providing acoustic coupling between the MEMS speaker unit and the second acoustic medium and at least one acoustic filter coupled to the first port or the second port, the at least one acoustic filter having at least one resonance lower than 6 KHz.
