Abstract

The utility model relates to an automatic switching device of for a mobile phone and an MP3 player. The utility model comprises a casing and a circuit board arranged inside the casing, wherein circuits on the circuit board comprise a power supply section, a mobile phone signals inductor section, a single voltage comparator section and a voltage conversion section; the circuits also comprise a four-pole plug and a stereoscopic plug; the four-pole plug is also connected with a microphone with a control switch; an output terminal of the circuits is connected with a stereoscopic socket for an external earphone microphone to plug in. The utility model adopts a battery for power supply and has simpler structure, and can be simultaneously connected with the mobile phone, the MP3 player, a small-size CD player, VCD player and DVD player and other sound sources. The utility model can be automatically switched to the state that the mobile phone is in use when inducting a mobile phone signal while listening to songs stored inside the MP3 player, and is particularly suitable for young people who are somewhat vogue and lead the fashion.

Description

Mobile phone, MP3 player automatic switchover device

Technical field:

The utility model relates to signal coupling technical field, refers in particular to a kind ofly can connect mobile phone and MP3 player simultaneously, and can automatically switch to mobile phone, the MP3 player automatic switchover device of mobile phone user mode when sensing mobile phone signal.

Background technology:

Along with development of science and technology, various electronics and communication product enter into common people's life from the laboratory.Mobile phone is a kind of radio communication product, can be together with each local people contact in the world, reached in unlimited time, the purpose that makes people arbitrarily link up, get in touch of limited region not, so be subjected to people's welcome deeply; The MP3 player is a kind of less player, it also is a kind of novel removable memory, and it can storage file and song, because its volume is little, and each business men also developed the player of different styles, so it is considered to fashion, fashionable product.People (particularly young man) are generally with mobile phone and MP3 player, can listen the song of MP3 player the inside storage in the time of idle,, when needs receive calls or during with the mobile phone dialing phone, the headset that needs to connect the MP3 player is earlier taken, answer or call and read, write and send mobile phone short message or the like again, some people is in order to reduce the radiation of mobile phone, also need to connect headset and then use on the mobile phone, cumbersome, caused bigger inconvenience to people.

Summary of the invention:

The purpose of this utility model is to provide a kind of automatic switchover device that can connect mobile phone and MP3 player simultaneously at the deficiencies in the prior art, can listen to the song of MP3 player the inside generally speaking, when needs use mobile phone, can realize the automatic switchover of mobile phone and MP3 player.

For achieving the above object, the utility model adopts following technical scheme:

It includes shell and places the interior circuit board of shell, include power supply, mobile phone signal inductor, univoltage comparator and voltage transformation part in the circuit of circuit board, also include four utmost point plugs and three-dimensional plug in the circuit, when the mobile phone inductor was sensed mobile phone signal, circuit can cut off automatically by three-dimensional plug input and be transformed into the mobile phone user mode.

Described four utmost point plugs also are connected with the microphone of band control switch.

The output of described circuit connects a three-dimensional socket that is used to peg graft outer headset.

Described power supply of the present utility model adopts the dc-battery power supply.

The utility model structure is comparatively simple, can connect mobile phone and MP3 player (can also be Small-sized C D, VCD, DVD player etc.) simultaneously, sense mobile phone signal during song in listening to the MP3 player, can automatically switch to the mobile phone user mode and the MP3 player is stopped using, be fit to very much than fashion, fashionable young man.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment:

See accompanying drawing 1,2, the utility model includes shell and places the interior circuit board of shell, and shell can adopt common material to be made into various external forms attractive in appearance.

Include power supply 10 in the circuit of circuit board, can respond to the mobile phone signal inductor 20 of mobile phone signal, the univoltage comparator 30 that pulse voltage can be amplified, and pulse voltage can be become the voltage transformation part 40 that galvanic current is pressed, also include all general common 2.5 4 utmost point plugs 50 of general mobile phone and common 3.5 three-dimensional plugs 60 in the circuit, common 2.5 4 utmost point plugs 50 are plugged in the headset socket of mobile phone, common 3.5 three-dimensional plugs 60 are plugged in the headset socket of MP3 player, and common 3.5 three-dimensional plugs 60 are applicable to the MP3 player, Small-sized C D, VCD, player and other sources of sound such as DVD.

Four utmost point plugs 50 also are connected with the microphone 80 of band control switch 70.

The output of circuit connects a three-dimensional socket 90 that is used to peg graft outer headset.Outer headset can be directly used in answering cell phone and MP3 player, and it can be common stereo headset.

With four utmost point plugs 50 be plugged on the mobile phone, three-dimensional plug 60 is plugged on the MP3 player, outer headset is plugged on the three-dimensional socket 90, generally speaking, can listen to the song in the MP3 player.When mobile phone inductor 20 is sensed mobile phone signal, incoming call or short message are for example arranged, univoltage comparator 30 can amplify this pulse voltage, through voltage transformation part 40 pulse voltage being become galvanic current again presses, delivering to audio frequency amplifier U2 then handles, make the audio frequency input circuit of MP3 player be cut off, and the input circuit of four utmost point plugs 50 of mobile phone is started working, can read or write, send short message this moment; Get final product incoming call answering if click control switch 70, realize conversation,, can recover the audio frequency input of MP3 player if end of conversation clicks control switch 70 again by microphone 80.

Power supply of the present utility model adopts the dc-battery power supply.

The utility model structure is comparatively simple, can connect mobile phone and MP3 player simultaneously, sense mobile phone signal during song in listening to the MP3 player, can automatically switch to the mobile phone user mode and the MP3 player is stopped using, as long as when not re-using mobile phone, click control switch 70, can recover the use of MP3 player, be fit to very much young man than fashion, fashion.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
