Fig. 1 is the perspective structure schematic diagram of the utility model inductive microphone preferred embodiment;
Fig. 2 is the module connection diagram of the circuit preferred embodiment of the utility model inductive microphone;
Fig. 3 is the circuit principle structure figure of the utility model inductive microphone circuit preferred embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Inductive microphone of the present utility model as shown in Figure 1, this microphone comprises conduction hand holding handle 1, described conduction hand holding handle 1 inside is provided with the microphone switch module and the touch sensible chip of electrical connection, described touch sensible chip is connected with touch sensitive point on the described conduction hand holding handle, and described microphone switch module is connected with the mains switch of described inductive microphone.Described microphone switch module and touch sensible chip all are positioned on the inductive microphone circuit 2, and inductive microphone circuit 2 is electrically connected by being connected electric wire 3 with described conduction hand holding handle 1.Also comprise the pick-up head 4 that is connected on the described conduction hand holding handle 1 on this inductive microphone, the voicefrequency circuit of described inductive microphone, supplying cell, described microphone switch module and touch sensible chip all are arranged at the inside of described conduction hand holding handle 1.
Pick-up head 4 places the upper end of conduction hand holding handle 1, is used to gather sound; Described voicefrequency circuit is that the sound that pick-up head 4 collects is handled, supplying cell and the power supply circuits that match are used for to inductive microphone circuit 2 power supply, and inductive microphone circuit 2 is used to realize switched by human body touch or non-touch the switching-on and switching-off state of inductive microphone.Also can respond to shell, depend on the hand holding handle outside, be used to gather the signal of human body touch at the sheathed again human body touch in the hand holding handle outside of existing microphone.
As shown in Figures 2 and 3, the circuit of inductive microphone of the present utility model comprises touch sensitive point, touch sensible chip, microphone switch module and power switching module; Wherein said touch sensitive point is arranged on the inductive microphone, is used to respond to the human body touch signal; Described touch sensible chip is connected with described touch sensitive point, is used to receive the induced signal of described touch sensitive point, and is translated into the receivable signal of described microphone switch module; Described microphone switch module is connected with described touch sensible chip, is used to receive the signal of described touch sensible chip, and judges whether to open inductive microphone; Described power switching module is connected with described microphone switch module, is used to control the operating circuit closure or openness of described inductive microphone.
When the spokesman hangs on, touch described touch sensitive point, described touch sensible chip receives induced signal, and this induced signal is sent to described microphone switch module, described microphone switch module is sent the signal of connecting the inductive microphone working power, inductive microphone is opened automatically, started working; When the spokesman put down microphone, described touch sensitive point did not receive induced signal, and then microphone automatic disconnection working power is closed automatically.Whether the utility model hangs on by the induction human body, reaches the function that opens and closes automatically microphone, and mode of operation is intelligence more, and prolonged the service time of battery in the wireless microphone, has saved the energy.Also can save simultaneously the device of manual toggle switch, reduce probability of malfunction.
The utility model can adopt in the single-chip microcomputer STC11 series one as the microphone switch module; Adopt touch sensible chip TCH01 as the touch sensible chip.In preferred embodiment as shown in Figure 2, single-chip microcomputer adopts STC11F04, and the touch sensible chip adopts TCH01A/H, and connects by the K1 pin of representing among Fig. 2, described touch sensitive point adopts induction metal plate, and this induction metal plate is connected to the pin P2 place among Fig. 2.Because single-chip microcomputer STC11F04 and chip TCH01A/H all have chip of the prior art, its pin definitions and parameter can be referring to its databooks, so do not repeat them here.
Be example with circuit shown in Figure 3 below, the method and the process of its induction are described: when human body not during the contact induction microphone, the pin KEY(of chip TCH01A/H is the touch-control pin) can not respond to voltage, pin OUT(is pin K1) output low level, and be connected with the P37 pin of single-chip microcomputer STC11F04, make the P17 pin output high level of single-chip microcomputer STC11F04, the time that its high level continues is about 3 seconds; Simultaneously, the P16 pin output low level of single-chip microcomputer STC11F04 is closed MPS microphone power supply.When human body touches inductive microphone, the pin KEY of chip TCH01A/H induces the weak voltage about 20 millivolts, pin OUT exports high level, at this moment, 3 seconds the high level of P17 pin output of single-chip microcomputer STC11F04, the P16 pin output high level of single-chip microcomputer STC11F04 is opened MPS microphone power supply, starts working.Described high level is 5 volts in this preferred embodiment.
The foregoing description only is a preferred embodiment of the present utility model, certainly the utility model also can adopt other microphone switch module and touch sensible chip, answer the on-off function of human body contact and control microphone as long as can realize sense of control, and be not limited to circuit elements device shown in Figure 3.
The utility model adopts the switch of human body touch induction sensing technology control wireless microphone, can avoid prolonging the useful life of microphone battery because the spokesman forgets the energy waste of closing MPS microphone power supply and causing; And switch frequent occasion the spokesman, each spokesman need not the switch of frequent operation microphone.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
