Abstract

The utility model relates to a change-over plug for single and double track. The utility model is composed of a change-over socket and a change-over plug. The change-over plug is composed of a metal core and a metal tube. The change-over socket is composed of an outer shell and jacks. The metal core 1 is connected with a spring piece 2 by conducting wires 7. The metal tube 10 is connected with a spring piece 3 by the conducting wires 7. The metal core and the metal tube, and the spring piece 2 and the spring piece 3 are all separated by insulators. The utility model is connected with the socket of the sounder. The change-over socket of the utility model is connected with a stereophonic plug. The utility model has the advantages of double-track effect and no change of the stereophonic effect.

Description

Change-over plug for single double-track

The utility model relates to a kind ofly can listen to monophonic audio, can listen to the dual track Plug with sound again, and particularly single, double sound channel changeover plug belongs to the sound equipment electrical accessorie.

We run into such certain situation through regular meeting: will listen to foreign language and some other broadcast programs that play in the radio station on be on duty time or the road.But can not influence other people, that must seek help from earphone certainly.

The semiconductor of Chu Shouing all is to be equipped with mono headset (the little earphone that promptly has the two-section plug) in the market, and this earphone need insert middle ear and fix, and because volume is little, turn round and look at reach certain audio frequency that is reached during volume between suitable higher-acoustic phase is when ear-piercing.

Listen with an ear, hearing is drop by half without foundation.Must add and be twice in order to reach same effects on hearing volume, increased the telecommunication noise, and the another ear also will be subjected to the interference of extraneous various sound.Listen after a period of time like this, will think that expand painful, hearing of middle ear obviously descends: be exactly to take earphone, also must could recover after a while.So also can cause sudden deafness for a long time, directly cause deafness.

And the stereophone of selling in the market just has many advantages than the former: because of being that ears are listened to and met physiologic habit, so can get rid of external interference, help concentrating one's energy.Body invests outside the ear in addition, and loudspeaker are big than the former, therefore listens to comfortablely, and tonequality is simple and honest, soft.

The purpose of this utility model designs a kind of plug and can listen monophonic audio can listen the dual track sound equipment again with two earphones, as long as plug is inserted list or dual track sound equipment, two earphones can both be heard sound, and the three-dimensional sound still can keep.

In the semiconductor of list → dual track patchplug insertion mono headset, the radio-cassette player television set, can hear the dual track sound equipment; Plug stereophone stereosonic effect is still arranged.

The purpose of this utility model is to realize like this, promptly connect metal-cored 1 with reed 2 usefulness leads 7, metal tube 10 usefulness leads 7 connect with reed 3, metal-cored 1 and metal tube 10 between and all separate between reed 2 and the reed 3 with insulator 4, single, double sound channel changeover plug connects with sound equipment socket 8, and the socket 6 of single, double sound channel changeover plug connects with stereo plug.

Accompanying drawing of the present utility model

Fig. 1 is the binodal plug circuit diagram of single, double sound channel changeover plug

Fig. 2 is the binodal plug split circuit diagram of single, double sound channel changeover plug

Fig. 3 is the binodal plug cutaway view of single, double sound channel changeover plug

Fig. 4 is the binodal plug split cutaway view of single, double sound channel changeover plug

Fig. 5 is the binodal plug of single, double sound channel changeover plug and the figure that connects of sound equipment electrical equipment

Each component names in addition in the accompanying drawing:

1, metal-cored 2, reed 3, reed

4, insulator 5, shell 6, socket

7, lead 8, sound equipment socket 9, stereo plug

10, metal tube

See that from Fig. 1, Fig. 2 single dual track changeover plug connects with reed 2 usefulness leads 7 by metal-cored 1, metal tube 10 usefulness leads connect with reed 3, metal-cored 1 and metal tube 10 between and all separate between reed 2 and the reed 3 with insulator 4.

See that from Fig. 3, Fig. 4 the binodal plug is similar to the single-unit plug, omit together described in its structure and connecting mode and Fig. 1, Fig. 2.

Fig. 5 represents that single, double sound channel changeover plug connects figure with sound equipment electrical equipment, promptly the plug in the earphone 9 is inserted in the socket 6 of changeover plug, and changeover plug inserts in the sound equipment socket 8 and gets final product.As just be inserted in the semiconductor can uppick dual track effect, if stereo set is stereosonic, stereophonic effect is constant.For the user is convenient, the lead 7 of crossover sub is changeable.The metal tube 10 of changeover plug has the plurality of specifications diameter, adapts to the size of various sound equipment sockets.

The advantage of this changeover plug:

1, make monophonic audio produce alliteration harmonic tone effect.

2, when only having a stereo videocorder at hand, the program in also can coming by it on record TV or the semiconductor.

3, it also can be used for the external stereo speaker of monophony radio-cassette player, TV.

And owing between two joint plugs of itself and the stereo jack section lead is arranged, so also just increased the total length of lead, can be at midnight during TV reception, long distance is used stereophone, promptly do not influence other people and have a rest and not reduce audibility again sense on the spot in person is also more arranged on the contrary, and again can be because watching distance is too near the damage eyesight.Be: thing is little, and effect is big.And cost is extremely low, produces easily.

Claims

1, a kind of single, double sound channel changeover plug, it is characterized in that, metal-cored (1) connects with lead (7) with reed (2), metal tube (10) connects with reed (3) with lead (7), all use insulator (4) to separate between metal-cored (1) and the metal tube (10) and between reed (2) and the reed (3), single, double sound channel changeover plug connects with sound equipment socket (8), and the socket of single, double sound channel changeover plug (6) connects with stereo plug.
