Acoustic transmission connection, headset with acoustic transmission connection, and uses of the acoustic transmission connection |
摘要 |
An acoustic transmission connection, e.g. for a headset (13), comprises a sound tube (2) through which speech signals can be transmitted from a first end (16) to a transducer, e.g. a microphone, in a housing or a housing part (3) of the headset. In the sound tube (2) and in the housing part (3), means are provided for acoustic impedance matching and possibly means for achieving acoustic directivity. |
