A microphone system includes a microphone with a microphone output for converting a first acoustic audio signal to a microphone signal, the system including: a head part including a loudspeaker with a loudspeaker input for converting a loudspeaker signal to a second acoustic audio signal; a first connector for connecting the system to an auxiliary device and including a housing and a first terminal; a unit for preprocessing the microphone signal having at least a first input connected to the microphone output, a first output connected to the loudspeaker input, and a second output connected to the first terminal. The unit is configured to: receive the microphone signal on the first input to form a input signal; and process the input signal to form first and second output signals on the first and second outputs, respectively, the first output signal and the second output signal based on the input signal.

A microphone includes a microphone base that has a first surface and a second surface. The microphone also includes a microelectromechanical system (MEMS) device coupled to the first surface of the microphone base. The microphone also includes a cover coupled to the first surface of the microphone base, such that the cover divides the first surface into a covered portion where the cover encloses the MEMS device, and a non-covered portion extending away from the cover. The microphone also includes one or more pads on the uncovered portion of the first surface of the base. The microphone also includes a port extending through the base from the first surface to the second surface.

The invention relates to a simple to produce electric component for chips with sensitive component structures. Said component comprises a connection structure and a switching structure on the underside of the chip and a support substrate with at least one polymer layer.

An apparatus includes a microelectromechanical system (MEMS) device having a diaphragm and a back plate; a clipping circuit coupled to the MEMS device, wherein the clipping circuit is configured to clip an output signal of the MEMS device so that the maximum signal drawn by a buffer is substantially constant over a temperature range; and an integrated circuit coupled to the clipping circuit, the integrated circuit including the buffer.

An example system includes a microphone sensor for an electronic device and a chamber coupled to the microphone sensor. The chamber is to be selectively filled with a fluid or having a vacuum therein. When the chamber is filled with the fluid, sound waves are allowed to travel through the chamber to the microphone sensor, and fluid pressure in the chamber causes an indicator to be in a first position. When the chamber has a vacuum therein, sound waves are prevented from traveling through the chamber to the microphone sensor and the vacuum in the chamber causes the indicator to be in a second position different from the first position.

The present disclosure relates to a hearing device having a microphone, where most of the microphone is shielded by an outer shielding of the hearing device. An inlet in the outer shielding allows sound from outside the hearing aid to travel to the microphone to be picked up by it. However, the combination of the microphone and the inlet results in the microphone becoming more sensitive at some audible frequencies. A damping filter positioned in connection with the inlet acts to counter the acoustic effect of the inlet by damping sound in the audible frequency range, where the microphone has increased sensitivity.

A signal converter includes a chamber, a first diaphragm, a second diaphragm, and a first converter. The chamber has a first opening at one end and a second opening at a second end opposite the first end. The first diaphragm is disposed so as to cover the first opening. The second diaphragm is disposed so as to cover the second opening. The first converter is disposed in the chamber and configured to generate a first signal based on a vibration of the first diaphragm.

A system and method for providing assistive listening for a plurality of listeners in an environment including a plurality of acoustic sources. A microphone array in combination with an acoustic beamforming processor configured to receive the acoustic signals within the environment and to process the acoustic signals based upon a target location of an acoustic signal selected on a listener-controlled interface device to generate a steered beam pattern. The acoustic beamforming processor further configured to transmit the steered beam pattern to the listener-controlled interface device based on the target location selected. The listener-controlled interface device configured to provide the steered beam pattern to an ear-level transducer of a hearing-impaired listener.

The invention relates to a simple to produce electric component for chips with sensitive component structures. Said component comprises a connection structure and a switching structure on the underside of the chip and a support substrate with at least one polymer layer.

An audio signal control apparatus includes a sound input circuit, a sound output circuit, and a control circuit. The sound input circuit is configured to receive an ambient sound signal from a microphone that captures ambient sound. The sound output circuit is configured to generate an output sound signal and transmit the output sound signal to a speaker to generate sound based on the output sound signal. The control circuit is configured to determine characteristics of the ambient sound based on the ambient sound signal received by the sound input circuit, determine a frequency band of the sound to be generated by the speaker based on the characteristics of the ambient sound, and control the sound output circuit to generate an output sound signal corresponding to the sound of the determined frequency band.
