Acoustic transmission connection, headset with acoustic transmission connection, and uses of acoustic transmission connection

Abstract

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.

Description

technical field [0001] The present invention relates to a sound transmission joint, a headphone using the sound transmission joint, and a hearing aid and a microphone using the sound transmission joint. Background technique [0002] Headphones and over-ear headphones are usually provided with a small microphone mounted at the end of an elongated and possibly flexible element so that the microphone is positioned in the user's mouth when the user wears the headset nearby. [0003] However, it is also known that a sound tube, also called a sound tube or the like, may be provided and consists essentially of a tubular member, a sound tube, one end of which is located near the user's mouth and the other The tip is mounted in a headset so that the speech signal transmitted by the sound tube is transmitted forward towards the microphone. [0004] Headphones of this type are known, for example, from US Patent Publication No. 5,761,298. This arrangement has the particular advantage...

AI Technical Summary

Problems solved by technology

In general, even if weight savings can be achieved, it is best not to use the same converter as speaker and microphone, as the desired voice quality cannot be achieved

Also, the structure shown has no means for attenuating standing waves in the sound tube if the entrance portion of the sound tube does not include filtering means, etc.
