Description

Expansion earphone

Technical Field

The utility model relates to an extension formula earphone.

Background

Many people share audio in public space, and audio is put outward and can cause noise pollution, and current earphone can only provide one person and use, if two are the vice earphone altogether, then cause the audio frequency to listen to the quality not high to easily cause the earplug to drop because one of them alone moves. The existing solution is to use dividers, which limit the number of users and are not portable.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an extension formula earphone that can solve above-mentioned problem for overcoming among the prior art electronic equipment's audio frequency is difficult to share the defect of listening to for many people through the earphone.

The utility model discloses an above-mentioned technical problem is solved through following technical scheme:

an extended earphone, comprising: the earphone comprises a plug, a general audio line, a first branch line, a second branch line, a deconcentrator, a left earplug, a right earplug and a protective sleeve, wherein one end of the general audio line is connected to the plug, the other end of the general audio line is connected to one ends of the first branch line and the second branch line through the protective sleeve, the other end of the first branch line is connected to the left earplug, the other end of the second branch line is connected to the right earplug, the deconcentrator is connected to the general audio line, and the deconcentrator is used for connecting the plug of an external earphone.

Preferably, the outer side of the deconcentrator is connected with a magic tape.

Preferably, the socket of the splitter is connected with a dustproof plug.

Preferably, a combiner is connected to the first branch line, and the combiner can be connected to the second branch line.

Preferably, the back surface of the left earplug is provided with a first magnet, the back surface of the right earplug is provided with a second magnet, and the first magnet and the second magnet can be mutually adsorbed.

On the basis of the common knowledge in the field, the above preferred conditions can be combined at will to obtain the preferred embodiments of the present invention.

The utility model discloses an actively advance the effect and lie in: the deconcentrator on the earphone can be used for expanding the audio signal to a plurality of earphones, so that the purpose that a plurality of people share the same audio frequency is achieved.

Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

in fig. 1, an extended earphone is shown, which comprises: a plug 100, a bus audio cord 200, a first leg 210, a second leg 220, a splitter 300, a left earpiece 400, a right earpiece 500, and a protective sleeve 600. One end of the bus audio line 200 is connected to the plug 100, the other end of the bus audio line 200 is connected to one end of the first branch line 210 and one end of the second branch line 220 through the protective sleeve 600, the other end of the first branch line 210 is connected to the left ear plug 400, the other end of the second branch line 220 is connected to the right ear plug 500, the splitter 300 is connected to the bus audio line 200, and the splitter 300 is used for connecting the plug 100 of the external earphone. The protective sleeve 600 can protect the connectors of the first branch line 210, the second branch line 220 and the main audio line 200, avoid the damage of the connecting structure and improve the reliability of the earphone.

In this scheme, extension formula earphone self can receive electronic equipment's electronic signal and convert the sound signal transmission to the listener in through the loudspeaker in left earplug 400 and the right earplug 500, and outside earphone can be through inserting deconcentrator 300 in, can receive electronic signal and convert the sound signal simultaneously, realizes the purpose of many people sharing audio frequency simultaneously. Theoretically, a plurality of extension earphones are connected in sequence, and wireless extension of audio signals can be achieved. In this embodiment, after actual tests are performed, after a plurality of expansion type earphones are connected in sequence, voltage signals of a left sound channel and a right sound channel of the earphones are attenuated to a certain extent, and the volume is also attenuated to a certain extent.

In order to protect the connection reliability between the splitter 300 and the bus audio line 200, a magic tape 310 is connected to the outside of the splitter 300. In addition, when the earphone cord is collected, the wound earphone cord can be tied together by using the magic tape 310, so that the earphone cord is prevented from being wound on other objects and being difficult to unwind.

In addition, a dust plug 320 is connected to the socket of the splitter 300. The dust plug 320 can prevent dust or liquid from entering into the splitter 300, thereby preventing the splitter 300 from being damaged.

The first branch line 210 is connected to a combiner 230, and the combiner 230 can be connected to the second branch line 220. The first branch 210 and the second branch 220 are connected by the combiner 230 after the listener has plugged the earplugs into the ears, thereby preventing the earphone cord from being excessively messy.

In this embodiment, the back surface of the left earplug 400 has the first magnet 410, the back surface of the right earplug 500 has the second magnet 510, and the first magnet 410 and the second magnet 510 can be attracted to each other. When the earphone is not used, the first magnet 410 and the second magnet 510 are attracted together, so that the disorder of the earphone wire is further avoided. In other earphones, the first magnet 410 and the second magnet 510 may be combined with a controller of the earphone, i.e., the volume is automatically turned off when the first magnet 410 and the second magnet 510 are attracted together.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
