具有声生成器和声放大器的MEMS扬声器装置
Abstract:
本发明涉及一种用于生成可听波长谱中的声波的MEMS扬声器装置(1)，其具有：壳体(2)，其具有导声通道(8)和布置在导声通道(8)的端部处的声出口(10)；至少两个MEMS扬声器(3)，其在壳体(2)内部被布置为使得由MEMS扬声器(3)生成的声波能够通过共同的导声通道(10)被引导到共同的声出口(10)；以及控制单元，其用于激励MEMS扬声器(3)。根据本发明，所述两个MEMS扬声器(3)中的一个MEMS扬声器在声出口(10)的方向上安放在另一个MEMS扬声器之后。此外，控制单元被构造为使得借助于该控制单元，能够为了提高MEMS扬声器装置(1)的最大声强将两个MEMS扬声器(3)激励为使得两个MEMS扬声器(3)中的第一MEMS扬声器被构造成声生成器(12)以用于起始波(15)，并且安放在其之后的第二MEMS扬声器(3)被构造成声放大器(13)以用于放大起始波(15)。
Abstract(English):

The invention relates to a MEMS loudspeaker arrangement (1) for generating sound waves in the audible wavelength spectrum, comprising a housing (2), which has a sound conduction channel (8) and a sound outlet opening (10) arranged at the end of said sound conduction channel (8), at least two MEMS loudspeakers (3) which are arranged in the housing (2) such that the sound waves generated by the MEMS loudspeakers (3) can be conducted to the common sound outlet opening (10) via the common sound conduction channel (8), and a control unit for controlling the MEMS loudspeakers (3). According to the invention, one of the two MEMS loudspeakers (3) is arranged downstream of the other in the direction of the sound outlet opening (10). The control unit is further designed such that, in order to increase the maximum sound intensity of the MEMS loudspeaker arrangement (1), the two MEMS loudspeakers (3) can be controlled such that the first of the two MEMS loudspeakers (3) is designed as a sound generator (12) for generating an initial wave (15) and the second MEMS loudspeaker (3) arranged downstream thereof as a sound amplifier (13) for amplifying said initial wave (15).
