A micromechanical component for a sensor device or microphone device. The component includes a diaphragm support structure with a diaphragm, a cavity formed in the diaphragm support structure and adjoined by a diaphragm inner side, and a separating trench structured through the surface of the diaphragm support structure and extends to the cavity and completely frames the diaphragm, and that is sealed off media-tight and/or air-tight using at least one separating trench closure material. An etching channel is formed in the diaphragm support structure, separately from the separating trench, and extends from its first etching channel end section to its second etching channel end section. The first etching channel end section opens into the cavity, and the second etching channel end section is sealed off media-tight and/or air-tight using at least one etching channel closure structure formed on an outer partial surface of the surface of the diaphragm support structure.

The present invention discloses a speaker having a vibrating system and a flexible circuit board. The vibrating system has a lower vibrating diaphragm with a first fastening portion, a second fastening portion, and a vibrating portion having a first and a second connecting portion and a middle portion. A vertical distance between a tangent line along a vertical vibrating direction at a first end of the first connecting portion and another tangent line along the direction of the middle portion is a first distance; another vertical distance between a tangent line along the direction at the second end of the second connecting portion and another tangent line along the direction of the middle portion is a second distance. Both the first and second distance are longer than a distance of the maximum elastic deformation of the flexible circuit board. The quality of speaker can be improved.

An audio processor configured for generating, for each of a set of one or more loudspeakers, a set of one or more parameters, which determine a derivation of a loudspeaker signal to be reproduced by the respective loudspeaker from an audio signal, based on a listener position and loudspeaker position of the set of one or more loudspeakers. The audio processor is configured to base the generation of the set of one or more parameters for the set of one or more loudspeakers on a loudspeaker characteristic of at least one of the set of one or more loudspeakers.

A sound producing structure includes: a frame body, a magnetic circuit system, a first diaphragm, and a second diaphragm. The frame body includes a receiving cavity, and the receiving cavity includes a first opening and a second opening that are located on two opposite sides of the frame body. The magnetic circuit system is located in the receiving cavity, and the magnetic circuit system includes a first magnetic channel and a second magnetic channel that are isolated from each other. The first diaphragm is disposed facing the first opening, a first voice coil is disposed on the first diaphragm, and a portion of the first voice coil extends into the first magnetic channel. The second diaphragm is disposed facing the second opening, a second voice coil is disposed on the second diaphragm, and a portion of the second voice coil extends into the second magnetic channel.

Apparatus configured to predict a diaphragm deflection signal, block-by-block, in overlapping time blocks based on the loudspeaker signal to obtain one diaphragm deflection signal block per time block. The apparatus is configured to determine a temporal position of a maximum deflection of a current diaphragm deflection signal block of a current time block within an overlap area with a subsequent time block and to calculate a level up to which the current diaphragm deflection signal block can be controlled without diaphragm over-deflection for the current time block by considering a comparison of the current diaphragm deflection signal block with a subsequent diaphragm deflection signal block or an estimation of the subsequent diaphragm deflection signal block from the current diaphragm deflection signal block at the temporal position. The apparatus is configured to attenuate the current diaphragm deflection signal block and to synthesize a modified loudspeaker signal.
