Description

A headphone conversion device

technical field

The utility model relates to a conversion device, in particular to an earphone conversion device.

Background technique

At present, most of the products such as general-purpose radios, MP3, MP4 and computers only provide a headphone jack. Restricted, so the prior art is still not perfect enough.

Contents of the invention

The purpose of the utility model is to provide an earphone conversion device with simple structure and practicality, which can simultaneously insert multiple earphones into one device and listen to the same audio content, so as to overcome the deficiencies in the prior art.

The utility model is constituted as follows: an earphone conversion device, including a plug and an earphone conversion shell, the earphone conversion shell is composed of a plug socket and an earphone jack, a spherical round head is arranged at one end of the plug, and a cone is arranged on the spherical round head. A contact shrapnel is arranged in the earphone jack, one end of the contact shrapnel is connected with the metal ring provided on the earphone jack port, and the other end of the contact shrapnel is connected with the spherical round head.

Two to four earphone jacks are arranged on the earphone conversion shell.

The connection end between the contact shrapnel and the spherical round head is arc-shaped.

A movable gap is provided between the contact shrapnel and the inner wall of the earphone jack.

Due to the adoption of the above technical scheme, the plug of the device is inserted into the player, and the earphones to be used are inserted into the earphone jack at the other end of the device, so that the effect of multiple earphones being plugged together to listen to music can be realized; In comparison, the utility model not only has the advantages of simple structure and practicality, but also has the advantages of ingenious design, convenient operation, convenient use, low cost, and the ability to insert multiple earphones into one device at the same time and listen to the same audio content at the same time.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Implementation of the present utility model: an earphone conversion device, comprising a plug 1 and an earphone conversion shell 2, the earphone conversion shell 2 is composed of a plug connection hole 3 and an earphone jack 4, and a spherical round head 5 is arranged at one end of the plug 1. The spherical round head 5 is provided with a tapered groove 6, and a contact shrapnel 7 is arranged in the earphone jack 4. One end of the contact shrapnel 7 is connected with the metal ring 9 provided at the port of the earphone jack 4, and the other end of the contact shrapnel 7 Connect with the spherical round head 5.

Two to four earphone jacks 4 are arranged on the earphone conversion shell 2 .

The connection end between the contact spring piece 7 and the spherical round head 5 is arc-shaped.

A movable gap 8 is provided between the contact spring 7 and the inner wall of the earphone jack 4 .

The contact shrapnel 7 is an existing product with certain elasticity. There are 2 to 4 pieces in each jack. The shape of the contact shrapnel 7 is an arc protruding toward the inside of the earphone jack 4. The contact shrapnel 7 plays the role of clamping the plug and ensuring good contact of the plug.

The plug 1 of this device is designed as a spherical shape, and is provided with a tapered groove 6 to facilitate the contact of the earphone plug to ensure the quality of sound transmission.

The plug 1 is inserted into players such as MP3, and other earphones are inserted in the earphone jack 4 of the earphone conversion device, so as to realize the function that a plurality of earphones are inserted together to listen to music.
