CN2150641Y - Change-over plug for single track and double track - Google Patents

Abstract

The utility model is mainly composed of a plug (1), a second series sheet (2), a third series sheet (3) and a casing (4). Stereo earphones are connected with ordinary monophonic transistor radios to use through the Switching plug, and two ears can feel sound at the same time; the listening effect is improved observably, and the influence of ambient noise is reduced. In addition, the jack and the plug of the utility model is right angle; when the plug is inserted in the radio, and the rotating angle of the earphone plug which is relative to the radio can be changed arbitrarily; the arbitrary change of the rotating makes the earphone plug of a miniature radio with the jack on back or side smoothly pasted to a casing body to protect leading wires of the earphone plug of a miniature radio from breaking.

Description

Change-over plug for single track and double track

The utility model relates to a kind of transistor radio earphone list dual track conversion equipment.

Aspect prior art, the pocket-size transistor radio low price, volume is small and exquisite, and is easy to carry, and power consumption is low, so popularity rate is very high.Particularly lecture of broadcast listening foreign language and the people that listens to the radio programme while taking a walk are more too busy to get away.But this broadcast receiver only has a common headphones, and audibility is very poor; If in noisy environment, just more do not heard.

The purpose of this utility model is: a kind of pocket single dual track changeover plug is provided, this changeover plug is inserted common monophony transistor radio earphone jack, be available stereophone broadcast listening, make two ears experience sound equipment simultaneously, very easy to use.

Below in conjunction with accompanying drawing structure of the present utility model is described:

Description of drawings:

Fig. 1 is the utility model stereogram;

Fig. 2 is the utility model front view;

Fig. 3 is the utility model upward view.

Wherein: 1. plug 2. bigeminy sheets 3. 3 sheets 4. shells 5. jack circles 6. headset plugs

The utility model is mainly consisted of (such as Fig. 2, shown in Figure 3) by plug (1), bigeminy sheet (2), three sheets (3), shell (4). Wherein, bigeminy sheet (2), three sheets (3) join with the corresponding contacts of plug (1), headset plug (6) respectively, and the angle of the jack of stereophone plug (6) and plug (1) is the right angle.

The utility model has two major advantages:

1. this plug is small and exquisite, can be connected to stereophone on the general semiconductor broadcast receiver and use, make two ears experience sound equipment simultaneously, significantly improve audibility, slacken influence of environmental noise greatly, and resistors match and power consumption are identical with common insert earphone

2. the angle of jack of self and plug is the right angle; after plug inserts broadcast receiver; headset plug can change arbitrarily with respect to wireless rotational angle, make some jacks rearward or the pocket radio set headset plug of side can be adjacent to housing smooth-goingly, protect its lead-in wire to make it not frangibility

Claims (2)

1, a kind of single dual track changeover plug is characterized in that: be made of plug (1), bigeminy sheet (2), three sheets (3), shell (4), bigeminy sheet (2), three sheets (3) join with the corresponding contacts of plug (1), headset plug (6) respectively.

2, single dual track changeover plug according to claim 1 is characterized in that: the angle of the jack of stereophone plug (6) and plug (1) is the right angle.
