Now also there is a kind of earphone with auto-switch function, but, the earphone great majority at present with auto-switch function are still to adopt mechanical switch, drive switch to realize conducting and the cut-out of earphone power supply by the opening and closing movement of wearing, this power supply control mode is without control switch manually, but the reliability of switch is poor, at present due to opening and closing movement erroneous judgement to cause power supply to be the probability of normally open very high, still can cause the waste of power supply and the generation of other uncertainty event.
Based on this, how a kind of earphone system that has automatic induction and detect and control function of utility model, can accurately automatically respond to and detect the use state of user to earphone, and then control the break-make of earphone power supply, is the technical problem that the utility model mainly solves.
Summary of the invention
The utility model adopts the problem of mechanical switch poor reliability in order to solve the existing earphone with auto-switch function, a kind of earphone system that has automatic induction detection and control function is provided, adopt the state of wearing of electronic induction detecting unit Test earphone, accuracy is high, can effectively avoid the waste of power supply.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
There is the earphone system that automatic induction detected and controlled function, comprise control unit, also comprise:
For automatically responding to the electronic induction detecting unit of the state of wearing of Test earphone, generate detection signal and be also sent to signal processing unit; Signal processing unit receives the detection signal that electronic induction detecting unit sends, and converts its processing to control unit discernible signal, and is sent to control unit; Described control unit receives after the signal of signal processing unit processes, produces control command and is sent to headset main body circuit unit.
Further, described electronic induction detecting unit is capacitance type sensor.
Or described electronic induction detecting unit is electro-optical pickoff.
Further, described signal processing unit is filtering and amplifying circuit.
Wherein, described control command comprises the control command that switches on or off circuit power for controlling, and wakes the control command of device in sleep or control device sleep up.
Compared with prior art, advantage of the present utility model and good effect are: the earphone system that has automatic induction detection and control function of the present utility model, comprise control unit, electronic induction detecting unit, and signal processing unit, wherein, electronic induction detecting unit is non-mechanical switches, can be directly take the head of human body as target, automatically the state of wearing of induction Test earphone, avoid the not high problem of mechanical switch erroneous judgement, accuracy, easy to use, and really reach energy-conservation object.The headset control method that has automatic induction and detect and control function of the present utility model, has avoided the erroneous judgement that mechanical switch causes by folding or the judgment mode that spaces out, the problem that accuracy is not high, and method reliability is high, energy-conservation.
Read by reference to the accompanying drawings after the detailed description of the utility model execution mode, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment system principle block diagram that the automatic induction of having of proposing of the utility model detected and controlled the earphone system of function.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in more detail.
The utility model provides a kind of earphone system that has automatic induction detection and control function, comprise control unit, electronic induction detecting unit, and signal processing unit, electronic induction detecting unit can be responded to the state of wearing of Test earphone automatically, and corresponding generation detection signal is also sent to signal processing unit; Signal processing unit receives the detection signal that electronic induction detecting unit sends, and converts its processing to control unit discernible signal, and is sent to control unit; Described control unit receives after the signal of signal processing unit processes, produces control command and is sent to headset main body circuit unit.
The earphone system with automatic induction detection and control function of the present utility model is applicable to all with the headphone such as power-supply system, control system.
For making the purpose of this utility model, technical scheme and advantage clearer, by take a kind of general headphone with power-supply system and control system as example, by reference to the accompanying drawings the utility model execution mode is described in further detail below.
Embodiment mono-, shown in Figure 1, the earphone system with automatic induction detection and control function in the present embodiment, comprise control unit, also comprise: electronic induction detecting unit, for automatically responding to the state of wearing of Test earphone, corresponding generation detection signal is also sent to signal processing unit; Signal processing unit, the detection signal sending for receiving electronic induction detecting unit, converts its processing to control unit discernible signal, and is sent to control unit; Described control unit receives after the signal of signal processing unit processes, produces control command and is sent to headset main body circuit unit.Electronic induction detecting unit in the present embodiment is non-mechanical switches, can be directly take the head of human body as target, automatically respond to the state of wearing of Test earphone, avoided the not high problem of mechanical switch erroneous judgement, accuracy, easy to use, and really reach energy-conservation object.
As a specific embodiment, described electronic induction detecting unit is capacitance type sensor, it realizes principle is that the capacitance of this capacitance type sensor causes variation in the time that earphone is worn or extractd, and the variation that described detection signal occurs according to this capacitance generates.
