Abstract (en)

[origin: WO2018108482A1] The invention relates to a MEMS microphone having good acoustic properties and a reduced failure probability due to faulty electrical connections. For this purpose, the microphone has a channel that connects a sound opening to a MEMS chip. The channel comprises a heterogeneous material from two different components which have different thermal properties.
