Abstract
The utility model discloses a mobile phone utilizing an external part of an audio output port to emit infrared, which comprises a mobile phone body and an external part of an audio interface. An audio socket is arranged on the mobile phone body, and an infrared pulse module and an audio amplification circuit are arranged on a mobile phone main board inside the mobile phone body. One end of the audio interface external part is an audio plug and the other end of the audio interface external part is an infrared LED (light-emitting diode) light. The audio plug is inserted into the audio socket, and the infrared pulse module is sequentially connected with the audio amplification circuit, the audio plug and the infrared LED light. The mobile phone utilizing the external part of the audio output port to emit infrared can use the audio output port to emit infrared and accordingly use functions of the mobile phone are broadened.
Description
Technical field
The utility model relates to cell phone apparatus, particularly a kind of mobile phone that utilizes the external infrared emission of audio output port.
Background technology
Mobile phone is the invention of American I T giant Motorola Inc. the earliest, using the widest in the world at present is so-called second generation mobile phone (2G), based on the GSM standard in Europe and the CDMA of the U.S., also have the IDEN network formats of Motorola, the PDC that Japan Area uses etc. in addition.They all are digital standards, except can carrying out voice communication, can also receive and dispatch note, WAP (wireless application protocol) etc.In the China's Mainland and Taiwan the most universal with GSM, the CDMA mobile phone is also very popular.Present whole industry is in third generation mobile phone (3G) transition process.
Telephone keypad part mobile phone has also comprised more function such as PDA, game machine, MP3, camera, photography, recording, GPS, online except typical telephony feature, the oriented trend that has the PDA development of cell-phone function.The mouthpiece of phone, earpiece and corresponding microphone, receiver all are contained on the single handle.Being once called as and being mobile phone, portable, mobile telephone, is telephone terminal portable, that can move in a big way.
Present mobile phone has often taken out infrared transmission module for cost squeeze and reduced volume.But the user still can need to use infrared (when wishing to use mobile phone as infrared remote control equipment such as the user) once in a while, can cause great inconvenience.
In view of this, those skilled in the art provide a kind of mobile phone that utilizes the external infrared emission of audio output port at the problems referred to above.
The utility model content
The utility model provides a kind of mobile phone that utilizes the external infrared emission of audio output port, has overcome the difficulty of prior art, can utilize the emission infrared ray of audio output port, has expanded the function of use of mobile phone.
The utility model adopts following technical scheme:
The utility model provides a kind of mobile phone that utilizes the external infrared emission of audio output port, comprise mobile phone body and audio port external piece, described mobile phone body is provided with audio sockets, cell phone mainboard in the described mobile phone body is provided with infrared pulse module and audio amplifier circuit, described audio port external piece one end is an audio jack, the other end is the infrared LEDs lamp, described audio jack is plugged on the described audio sockets, and described infrared pulse module connects described audio amplifier circuit, audio jack and infrared LEDs lamp successively.
Preferably, described mobile phone body is a smart mobile phone.
Owing to adopted above-mentioned technology, compared with prior art, the mobile phone that utilizes the external infrared emission of audio output port of the present utility model can utilize the emission infrared ray of audio output port, has expanded the function of use of mobile phone.
Further specify the utility model below in conjunction with drawings and Examples.

Embodiment
Introduce a kind of specific embodiment of the present utility model below by Fig. 1 to 5.
Embodiment 1
Shown in Figure 4 and 5, a kind of mobile phone that utilizes the external infrared emission of audio output port of the present utility model, comprise mobile phone body 1 and audio port external piece 2, described mobile phone body 1 is provided with audio sockets, cell phone mainboard in the described mobile phone body 1 is provided with infrared pulse module and audio amplifier circuit, described audio port external piece 2 one ends are audio jack 21, the other end is an infrared LEDs lamp 22, described audio jack is plugged on the described audio sockets, and described infrared pulse module connects described audio amplifier circuit, audio jack and infrared LEDs lamp successively.Described mobile phone body 1 is a smart mobile phone.
Actual operating position of the present utility model is as follows:
The mobile phone that utilizes the external infrared emission of audio output port of the present utility model, as shown in Figure 1, adopt the mode of modulation during modulation Infrared Remote-Control Sending data, promptly the carrier wave of data and certain frequency is carried out AND-operation, can improve emission effciency like this and reduce power supply power consumption.Modulated carrier frequencies generally at 30khz between the 60khz, that great majority use is 38kHz, the square wave of duty ratio 1/3.As above figure is exactly that a ultra-red order modulation is converted into the signal of telecommunication afterwards, amplifies the back by the infrared-emitting diode emission via triode, and allows infrared reception original paper receive the also process of demodulation.
From the basic principle basic process that it had as can be seen of infrared emission as shown in Figure 2.
We can understand like this from this process, and ultrared instruction can be regarded a concrete order as, corresponding this a kind of coding of this order.Become pulse signal after the coded modulation.Because pulse signal is very faint, be not enough to promote the infrared LED emission, so, at first can send again through amplifying circuit.
As shown in Figure 3, so we can utilize the function of voice playing to realize similar functions.
The mobile phone of the external infrared emission of audio output port that utilizes of the present utility model utilizes software to simulate ultrared pulse, and as the input of audio amplifier circuit, after the amplification again by audio output port (as the earphone mouth) output.As long as infrared LEDs is installed in the work that can carry out infrared output on the similar equipment of headset plug like this.
As shown in Figure 4, when this device was inserted on the mobile phone, the tonepulse through ovennodulation that can utilize earphone mouth mobile phone to be exported was launched infrared signal.
In summary, owing to adopted above-mentioned technology, the mobile phone that utilizes the external infrared emission of audio output port of the present utility model can utilize the emission infrared ray of audio output port, has expanded the function of use of mobile phone.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
