In order to achieve the above purpose, the present utility model adopts the following technical scheme:

a hearing aid with randomly adjustable direction comprising: the portable telephone comprises a soft PVC sound transmission tube, a telephone receiver and an earcap, wherein one end of the soft PVC sound transmission tube is connected with the telephone receiver, and the earcap is fixed on the telephone receiver.

Preferably, a first enameled wire, a second enameled wire and a stainless steel wire are arranged in the soft PVC sound transmission tube.

Preferably, the tensile strength of the soft PVC sound transmission tube is 10N/mm ² ～25N/mm ² Elongation is 100% -450%, and shrinkage is 2% -2.3%.

A hearing aid with randomly adjustable direction, comprising said receiver, further comprising: the body is connected to one end of the soft PVC sound transmission tube.

Preferably, a microphone is mounted on the body.

Preferably, a switch button and a sound button are arranged on the machine body.

Compared with the prior art, the hearing aid and the receiver with the direction capable of being adjusted at will can be provided, the direction can be adjusted at will through the soft PVC sound transmission tube, and the use is convenient.
