MEMS loudspeaker arrangement comprising a sound generator and a sound amplifier

MEMS loudspeaker arrangement for generating sound waves in an audible wavelength spectrum, comprising:

• a housing that defines an interior with a sound-conducting channel elongating in a downstream direction to an end thereof, the housing further defining a sound outlet disposed at the end of the sound-conducting channel;
• a first MEMS loudspeaker and a second MEMS loudspeaker disposed in the interior of the housing and downstream of the first MEMS loudspeaker in the direction of the sound outlet, wherein the MEMS loudspeakers are disposed so that the sound waves generated by the MEMS loudspeakers conducts downstream through the sound-conducting channel to the sound outlet;
• and
• a control unit connected to control the MEMS loudspeakers and configured for controlling the first MEMS loudspeaker to function as a sound generator for generating an initial wave and the second MEMS loudspeaker to function as a sound amplifier for amplifying this initial wave to form a resulting wave;
• and
• wherein the housing further defining a common cavity shared by the first MEMS loudspeaker and the second MEMS loudspeaker, wherein the common cavity is disposed in opposition to the sound-conducting channel.
