Abstract
The invention discloses a method for switching radio channels. The method is applied to a system consisting of a headset and a system master chip FM (Frequency Modulation) radio. The method comprises the following steps that: 1, a sensor arranged in the headset can detect whether the headset shakes, and when the headset shakes, the sensor acquires shaking information, converts the shaking information into electric signals and transmits the electric signal to a system master chip; 2, the system master chip judges whether the number of the electric signals generated by shaking in a time period T exceeds a preset threshold N; 3, when the number of the electric signals received in a time period T reaches the preset threshold N, the electric signals are effective input signals, and the electric signals are conveyed to the FM radio; and 4, the FM radio decodes the electric signals and then switches the radio channels. Compared with the prior art, the method disclosed by the invention is simple and convenient because the channels are switched through the shaking of the headset.

Fig. 1 is method flow diagram of the present invention.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present invention and advantage are carried out more deep annotation.
Method flow diagram of the present invention as shown in Figure 1, a kind of method of switching radio channels, described method are applied to may further comprise the steps in the system that earphone, the master chip FM of system broadcast receiver form:
Whether step 1, the built-in transducer Test earphone of earphone produce and rock, and when the earphone generation was rocked, transducer obtained this and rocks information, and changes into the signal of telecommunication, flows to system's master chip;
Step 2, system's master chip judge whether the number of the signal of telecommunication that rocks generation in period of time T surpasses pre-set threshold value N;
Step 3, when the number of the signal of telecommunication of receiving in period of time T reaches pre-set threshold value N, be effective input signal, send this signal of telecommunication to the FM broadcast receiver;
Step 4, FM broadcast receiver are deciphered rear switching radio channels with the signal of telecommunication.
Further, described transducer is gravity sensor, the rocking back and forth of Test earphone.
Further, the described time cycle is the sampled signal cycle, and systemic presupposition is set to 1～2 second.
Further, described pre-set threshold value N obtains the number of the signal of telecommunication for sampling, be the systemic presupposition value, 3～5.
Further, the number that the described effective input signal of step 3 obtains the signal of telecommunication for sampling is positioned at the threshold values interval, and surpassing higher limit or being lower than lower limit is invalid input, for example being lower than 3 rocks, then be judged as the user and touch because of carelessness the earphone misoperation, be judged as invalid input, do not carry out switching channels, when rocking above 5, then having surpassed human physiology operating limit, for example be generally by bus or aircraft acutely rocks, is not manual operation, be judged to be invalid income, do not carry out channel and switch.
A kind of system of method of described switching radio channels comprises:
Whether transducer produces for detection of earphone and to rock, and when earphone produces when rocking, transducer obtains this and rocks information, and changes into the signal of telecommunication, flows to system's master chip;
