Description

The mobile phone that has multifunctional headphone

Technical field

The utility model belongs to the technical field of mobile terminals, in particular, relates to the mobile phone that earphone is provided with remote controller exactly.

Background technology

People more and more note health problem now, therefore often use the crowd of mobile phone that the electromagnetic radiation that produces in the mobile phone communication is more and more paid close attention to, and in order to make mobile phone away from human body head and the convenient purpose of using, the user has selected the use earphone.And owing to the mobile phone that has the MP3 playing function is universal day by day, the use amount of earphone increases greatly, and the user uses the number of times of earphone also more and more frequent, and earphone has become the standard configuration that must have on a mobile phone.

But present handset earphone can only realize individual palpation key and voice and transmit simple function, if realize making a phone call and check that incoming call etc. is when the fairly simple function of mobile phone end, even using earphone also can only check from the mobile phone end.And have very many mobile phones to have the function that built-in MP3 plays now, action need mobile phone itself control when using this function is finished.Because present earphone can only receive calls, want to realize checking incoming calls record and MP3 music, the user of use earphone still needs to take out mobile phone and carries out feature operation, and is very inconvenient.

Summary of the invention

The purpose of this utility model is exactly can only receive calls for the earphone that solves on the present mobile phone, can not carry out the limitation of other feature operations, a kind of mobile phone that has multifunctional headphone is provided, on earphone, increase a control unit, realize the far-end control of mobile phone basic function, the user is operated easily.

To achieve these goals, the earphone that the utility model comprises mobile phone, is connected with mobile phone by earphone interface, earphone interface comprises data/address bus and sound bus, also comprise the remote controller that is connected with mobile phone by data/address bus on the earphone, display screen that is connected with remote controller and button, and the Mike and the receiver that are connected with mobile phone by the sound bus.

Earphone interface needs transmitting data information and acoustic information, and 10 needle interfaces of choice criteria comprise 10 needle interface slots on the mobile phone, comprise 10 needle interface plugs on the earphone.

Remote controller on the earphone is to have I ²The single-chip microcomputer of C bus, the single-chip microcomputer of the 87LPC762 model of employing Philips.Owing to the requirement of volume and weight, display screen and button all need miniaturization on the earphone, and wherein display screen adopts 16 * 64 double-colored LCD LCDs, and the keyboard region on the earphone has 4 buttons.

The utility model can be widely used on the various mobile phones, and the user of mobile phone finishes mobile phone operation commonly used by the remote controller of earphone, has increased the ease for use of mobile phone products.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is a general structure block diagram of the present utility model;

Fig. 2 is the circuit diagram of remote controller among embodiment of the utility model;

Fig. 3 is the keyboard region circuit diagram that embodiment of the utility model adopts 4 buttons;

Fig. 4 is the interface schematic diagram of mobile phone and earphone in the utility model.

Embodiment

As shown in Figure 1, it is the general structure signal of mobile phone and earphone, earphone 2 is connected on the mobile phone 1 by receiver J-Horner 3, communication between earphone 2 and the mobile phone 1 comprises sound bus and data/address bus, voice data on the mobile phone arrives receiver by the sound bus and plays voice and MP3 data, cellie's sound is converted to the signal of telecommunication by earphone Mike, handles in mobile phone 1 through the sound bus transfer.

Earphone 2 in the utility model also comprises display screen 2-2 part, key zone 2-3 part and remote controller 2-1.Because earphone 2 need be easy to carry about with one and the controller on earphone does not need to realize complicated especially function yet, be subjected to the restriction of weight again, so display screen 2-2 does not need too big, can select picture element for use is 32 * 64 or 16 * 64 common double-colored LCD LCDs, key zone 2-3 partly is provided with 4 buttons, realizes feature operation commonly used.

As Fig. 2, shown in Figure 3, the built-in single-chip microcomputer of the remote controller 2-1 of earphone can be selected the single-chip microcomputer of the 87LPC762 model of Philips, and single-chip microcomputer has 20 pins, its inner integrated I ²The C bus control unit is provided with I ²The C bus is from pattern, receives the data that the mobile phone end transmits.Control datas such as LCD data that the mobile phone end sends and sleep are by this I ²The C bus directly is sent to single-chip microcomputer.

Key zone 2-3 partly is provided with 4 buttons, and the user realizes feature operation commonly used by button, if there is key-press event to take place, sends a signal to the processor of mobile phone end by the GPIO P0.0 of single-chip microcomputer, and mobile phone end processor passes through I ²The C bus reads button data and handles.

LCD display 2-2 on the earphone and key zone 2-3 control by single-chip microcomputer, and the LCD interface is the spi bus mode, and single-chip microcomputer is initialization LCD when control desk powers on, when normal operation I ²The video data of C bus transfer refreshes to LCD.Keyboard adopts the mode of array scanning to read key information, only handles the message of a button simultaneously.Single-chip microcomputer itself is deal with data not, the mobile phone end inserts the back at earphone and sends video data to single-chip microcomputer according to self corresponding state, single-chip microcomputer refreshes the LCD screen according to the video data that sends, single-chip microcomputer is according to the timer keyboard scan array that self is provided with simultaneously, send keyboard array information to mobile phone end, the event handling that the mobile phone end responds according to key information.

LCD display by earphone and button can the operation part cell-phone functions, can realize the operation that some users use always, check time, signal, battery electric quantity, phone directory, message registration and note, incoming call as demonstration, call, select music, realize the functions such as various controls of music.These operations commonly used are finished by the remote controller of earphone, can reduce the mobile phone use amount, increase the ease for use of mobile phone products.

Remote controller 2-1 power supply in the earphone is provided by mobile phone 1, and the mobile phone end just can select whether to power the electric quantity consumption of control single chip computer like this.

As shown in Figure 4, the earphone interface 3 between mobile phone 1 and the earphone 3 need adopt 10 needle interfaces owing to increase data communication, and wherein CON1 adopts standard 10 needle interface slots, is normal component, and pin definitions is corresponding with headset connector.CON2 is the connected mode of earphone cord, can be connected respectively to headset earpiece and Mike (pin one～4) by pin definitions, and remote controller (pin 5～9).Mobile phone 1 control and earphone 3 between carry out communicate to connect.
