The first electroacoustic conversion unit 100 has a fixed electrode 101, an oscillation film 105 that is disposed facing the fixed electrode 101 and that oscillates in accordance with a difference in potential generated with respect to the fixed electrode on the basis of an electrical signal, and a support member 107 that supports a partial region of the oscillation film 105 and that brings part of the oscillation film 105 into contact with the fixed electrode 101. The first electroacoustic conversion unit 100 and the second electroacoustic conversion unit 200 are disposed facing one another with the partition member 30 sandwiched therebetween such that a sound-emitting part 100a and a sound-emitting part 200a are inserted into an acoustic outlet 2a. The partition member 30 supports the support member 107 and a support member 207

摘要： A MEMS microphone (100) includes a membrane (400), a spring (405), and a first layer having a backplate (515), and a first OTS structure (415). The spring (405) has a first end (408) coupled to the membrane (400), and a second end (413) mounted to a support. The first OTS structure (415) is released from the backplate (515) and coupled to a structure other than the backplate, and is configured to stop movement of the membrane (400) in a first direction after the membrane (400) has moved a predetermined distance.

摘要： The invention relates to an acoustic absorber comprising an absorption layer (1a, 1b) composed of an open-pored porous material. According to the invention, the open-pored porous material is flexurally stiff in such a way that the absorption layer (1a, 1b) is stimulated to flexurally oscillate when sound waves impinge on the absorption layer and the absorber can absorb sound waves of a first frequency range because of the inflow of air into the open-pored porous material of the absorption layer and can absorb sound waves of a second frequency range that comprises lower frequencies than the first frequency range because of the stimulation of flexural oscillations of the absorption layer. The invention further relates to an acoustic transducer and to a method for producing an acoustic absorber or an acoustic transducer.

摘要： A loudspeaker apparatus (10) is provided for producing time and phase-coherent sound waves, substantially hemispherical in shape, directed toward a listening area. The loudspeaker apparatus includes a simply-constructed inverted speaker cone (18) designed to produce primarily low and medium frequencies, a high frequency speaker (52) uniquely positioned above and behind the axis of the cone (18) to supplement the high frequencies, and absorbing material (40, 36, 38) disposed inter alia at a rear portion and at the smaller end (20) of the cone (18) to produce the hemispherical-shaped sound waves and direct them toward the listening area.
