Abstract
A MEMS package comprises a first speaker arrangement configured for emitting sound in a first audio frequency range and a second speaker arrangement configured for emitting sound in a different second audio frequency range.
Claims20
A MEMS device comprising:
- a first speaker arrangement being configured for emitting sound in a first audio frequency range;
- and
- a second speaker arrangement being configured for emitting sound in a different second audio frequency range.
An audio device comprising:
- a housing;
- and
- a MEMS device contained in the housing, the MEMS device configured for providing acoustic sound in a first audio frequency range and in a second audio frequency range, the MEMS device including:
- a first speaker arrangement configured to emit sound in the first audio frequency range;
- and
- a second speaker arrangement configured to emit sound in the second audio frequency range, the second audio frequency range being different than the first audio frequency range.
3 more elements
A MEMS device comprising:
- a first speaker arrangement being configured for emitting sound in a first audio frequency range, the first speaker arrangement being configured as one of an ultrasonic demodulation speaker and a thermoelectrical speaker;
- and
- a second speaker arrangement being configured for emitting sound in a different second audio frequency range, the second speaker arrangement being configured as a piezoelectrically driven membrane structure configured to generate the sound in the second audio frequency range.
