A MEMS transducer package (1) comprises a semiconductor die element (3) and a cap element (23). The semiconductor die element (3) and cap element (23) have mating surfaces (9, 21). The semiconductor die element (3) and cap element (23) are configured such that when the semiconductor die element (3) and cap element (4) are conjoined, a first volume (7, 27) is formed through the semiconductor die element (3) and into the semiconductor cap element (23), and an acoustic channel is formed to provide an opening between a non-mating surface (11) of the semiconductor die element (3) and either a side surface (10, 12) of the transducer package or a non-mating surface (29) of the cap element (23).

An acoustic input module and an electronic device including the same are provided. The electronic device includes at least first and second transducers mounted on one surface of a circuit board, a control module mounted on the circuit board for controlling the transducers, and a plurality of sound input holes formed in a housing of the electronic device. The first transducer receives a sound along a first directional path through a first sound input hole and converts the received sound into an electrical signal, and the second transducer receives a sound along a second directional path through a second sound input hole and converts the received sound into an electrical signal. Since the transducers detect sounds originating along different paths, the electronic device can include a multi-channel recording function with an ability to reinforce sound of a specific object and attenuate other sound.

A microphone module (2) for an electronic device (1) is provided. The microphone module (2) includes a window (10) having at least one microphone hole (111) in a part of an edge of the window (10), a microphone (50) installed in a position corresponding to the microphone hole (111) of the window (10), and a case frame (20) coupled with the window (10) and forming an appearance of the electronic device (1). The microphone module (2) receives an external voice through the microphone hole (111) of the window (10).
摘要:
An acoustic device for forming a wall of sound underwater. Walls of sound are useful in water for guiding fish away from areas. Hitherto, systems have used bubbles of water to facilitate the speed of travel of the sound. Those systems have suffered from the ability to maintain a consistent wall of bubbles and have often been inefficient. The present invention seeks to provide an acoustic device for forming a wall of sound underwater and comprises a transducer connected to an acoustic waveguide. The waveguide comprises one or more projections, whereby sound generated by the transducer travels along the projection or projections to form the wall of sound. The waveguide may typically comprise compressible projections formed from neoprene. These projections are arranged in a fan or frond shape. In addition or alternatively, the projections may be laminar. The projections could be of different lengths. The location, arrangement and lengths of the projections are all suited to the underwater location to maximise the effectiveness of the wall of sound.

An acoustic device that has a neck loop that is constructed and arranged to be worn around the neck. The neck loop includes a housing with a first acoustic waveguide having a first sound outlet opening, and a second acoustic waveguide having a second sound outlet opening. There is a first open-backed acoustic driver acoustically coupled to the first waveguide and a second open-backed acoustic driver acoustically coupled to the second waveguide.
