Sound converter arrangement with mems sound converter

The present invention relates to a sound transducer assembly (1) with a mems sound transducer (21) for generating and/or detecting sound waves in the audible wavelength spectrum, which comprises a first cavity (41), and an asic (11) electrically connected to the mems sound transducer. In accordance with the invention, the asic (11) is embedded in a first substrate (10), and the first mems sound transducer (21) is arranged in a second substrate (20). ... Usound Gmbh

Circuit board module comprising a continuous cavity, associated sonic transducer assembly, and production method

The invention relates to a circuit board module (2) for a sound transducer assembly (1) for generating and/or detecting sound waves in the audible wavelength spectrum, with a circuit board (4), which features a recess (6) with a first opening (7), and at least a part of a mems sound transducer (5), which is arranged in the area of the first opening (7), such that the recess (6) at least partially forms a cavity (9) of the mems sound transducer (5). In accordance with the invention, the recess (6) features a second opening (8) opposite to the first opening (7), such that the recess (6) extends completely through the circuit board (4). ...

Loudspeaker arrangement

A loudspeaker arrangement for a plurality of mems loudspeakers for generating sound waves in the audible wavelength spectrum includes a housing, which has a sound conduction cavity and at least one sound outlet opening, and at least two mems loudspeakers, arranged in the interior of the housing opposite and spaced apart from each other by the sound conduction cavity. Each mems loudspeaker has a cavity in the region of their opposite faces. ... Usound Gmbh

Mems loudspeaker arrangement comprising a sound generator and a sound amplifier

A mems loudspeaker arrangement for generating sound waves in the audible wavelength spectrum includes a housing that defines a sound-conducting channel and a sound outlet arranged at the end of the sound-conducting channel. At least two mems loudspeakers are arranged in the interior of the housing so that they generate sound waves through the sound-conducting channel to the sound outlet. ... Usound Gmbh

Mems loudspeaker having an actuator structure and a diaphragm spaced apart therefrom

The invention relates to a mems loudspeaker (1) for generating sound waves in the audible wavelength spectrum, with a carrier substrate (2) that features a sub-strate cavity (6) with two substrate openings (7, 8), which are formed on two opposite sides of the carrier substrate (2), an actuator structure (3), in particular a piezoelectric actuator structure, which is arranged in the area of one of the two substrate openings (7, 8) and is connected to the carrier substrate (2) in its edge area, and a membrane (4) anchored in its edge area, which, by means of the actuator structure (3), can be set into vibration for generating sound waves. In accordance with the invention, in a cross-sectional view of the mems loudspeaker (1), the membrane (4) is spaced at a distance from the actuator structure (3), such that an intermediate cavity (13) is formed between these two. ...
