Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the block diagram according to the earphone interface treatment circuit that is used for portable terminal of the utility model embodiment;
Fig. 2 is the schematic diagram according to corresponding relation between the analog signal of the utility model embodiment and the digital signal.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
According to embodiment of the present utility model, provide a kind of earphone interface treatment circuit for portable terminal.
Fig. 1 is the earphone interface treatment circuit that is used for portable terminal according to the utility model embodiment, and as shown in Figure 1, this circuit comprises: receiver module 10 and modular converter 20, wherein:
Describe below with reference to Fig. 2.At first, corresponding relation between analog signal and the digital signal need to be set.For example: the analog signal representative digit signal 1 of 2KHZ, the analog signal representative digit signal 0 of 1KHZ.Certainly, other corresponding relation can also be set, for example: the analog signal representative digit signal 1 of 4KHZ, the analog signal representative digit signal 0 of 2KHZ, the utility model does not limit this.
After receiver module 10 receives analog signal, modular converter 20 is according to the analog signal that sets in advance and the corresponding relation between the digital signal, and according to frequency shift keying (Frequency Shift Keying, abbreviation FSK) technology is digital signal with described analog signal conversion, and the data-signal of outer handset just enters interior of mobile phone by earphone interface like this.Similarly, modular converter 20 also has the function that the digital signal of interior of mobile phone is converted to analog signal, by earphone interface analog signal is sent to outer handset more afterwards, has realized the purpose of mobile phone by earphone interface and external device data communication.
In an embodiment of the present utility model, described modular converter 20 is arranged at application processor (Application Processor is called for short AP), that is to say, above-mentioned translation process is responsible for by AP.Generally speaking, mobile phone all is by AP or Modem(communication module) carry out data communication with the outside.If with the module of PERCOM peripheral communication be AP, then directly process in this locality.If with the module of PERCOM peripheral communication be Modem, then the bus of AP by interior of mobile phone communicated by letter with Modem, sends data to Modem and processes.In addition, described modular converter 20 can also be the independently module that is arranged on separately in the portable terminal.
In an embodiment of the present utility model, L channel pin or the R channel pin of earphone interface is electrically connected with battery module, like this, just can charge or power by this earphone interface.Certainly, also have the module such as charging module in the circuit and cooperate and charge or power, do not give unnecessary details herein.
