Abstract

An acoustic therapy device is provided including a housing, an electro-acoustic transducer, a coupling element and coupling cushions. The electro-acoustic transducer is arranged in the housing which includes a shell. The coupling element has a coupling surface flush with edges of the shell. Another coupling surface of the coupling element is on the sound irradiation surface of the transducer and sound waves from the sound irradiation surface are directly coupled into the coupling element. An elastic coupling cushion is connected to a surface of the coupling element. One coupling surface of the coupling element and an exterior coupling surface of the coupling cushion define a sound advance path the length of which may, along with a penetration depth of the sound waves, be varied.
