The corresponding TV functions that will realize of each touch key-press, for example volume increases, volume reduces etc., in prior art, no matter whether exist and carry out luminous prompting to touching, touch detection circuit 1 is when touch key-press being detected and be touched, function choosing-item corresponding to touch key-press corresponding to touch detection circuit 1 judgement, and then send corresponding function control signal to functional circuit, functional circuit is carried out the function corresponding with touch key-press.About the detection judgement of this part touch key-press and the control of functional circuit realization, be prior art, repeat no more herein.
Because drive circuit can drive sound circuit, carry out work, by sound circuit, carry out sound prompting, sound prompting is more direct, particularly for the elderly, sound prompting is very effective, has effectively overcome the defect that prompting that flashing light exists is missed.
Fig. 2 is the circuit diagram of the first embodiment of touch cue circuit of the present utility model;
Described touch key-press 3 is capacitance type touch key, and quantity is 7, as S1-S7 in figure, and the following functions option that difference is corresponding: power supply, reset, menu, channel down, channel add, sound subtracts, sound adds.Certainly, the quantity of touch key-press and function can according to circumstances be determined, and do not limit.
Described drive circuit 4 comprises: the triode Q1 of resistance R 1, pull-up resistor R2, NPN type and at least one diode corresponding with the number of described touch key-press, in the present embodiment be: diode D9-D15.Described sound circuit 5 comprises buzzer H1.
Described touch detection circuit 1 comprises a touch detection chip U1, and the model adopting in the present embodiment is JST8D080.JST8D080 had both had common touch measuring ability, also had simple micro controller function simultaneously.Touch and touch input port TS_1-TS_7 comprising of detection chip U1, and touch one to one output port P01-P07 with TS_1-TS_7.It is effective that touch output port P01-P07 is output as high level, when the capacitance type touch key connecting when touch input port is touched capacitance variations, corresponding touch output port can be given tacit consent to output high level, and (this is for touching the inherent function of detection chip U1, without user's later stage programming Control), this is prompting control signal.
Capacitance type touch key S1-S7 is connected to respectively the corresponding touch input port TS_1-TS_7 of described touch detection chip U1 one to one, the touch output port P01-P07 corresponding with described touch input port of described touch detection chip U1 is connected to respectively the positive pole of corresponding diode D9-D15 one to one, after the negative pole parallel connection of all described diode D9-D15, by described resistance R 1, be connected to the base stage of described triode Q1, the grounded emitter of described triode Q1, the collector electrode of described triode Q1 is connected to the negative pole of described buzzer H1, the positive pole of described buzzer H1 is connected to positive source by pull-up resistor R2.
The operation principle of the first embodiment is as follows:
When capacitance type touch key is not touched, touching output port P01-P07 acquiescence is all output low level, and all diode D9-D15 all end, therefore, triode Q1 cut-off, buzzer is not worked.
When certain capacitance type touch key is touched, touch touch input port corresponding to detection chip U1 and its capacitance variations detected, corresponding touch output port output high level, so connected diode current flow, also conducting of triode Q1, so buzzer carries out sounding reminding.
It should be noted that, although had in prior art to utilize and touched the function that detection chip U1 judges concrete touch key-press, but touch output port output high level herein for touching the intrinsic function of detection chip U1, do not need user to fire program in the later stage and control.Therefore, it is to rely on hardware to realize completely that pronunciation is reminded, and reacts rapider.
Introduce another kind of another kind of implementation of the present utility model below, with reference to figure 3.
The second embodiment is from the different of the first embodiment, removed diode D9-D15, touch detection chip U1 and be connected directly to described drive circuit 4 by an output port, in figure 3, the base stage of described triode Q1 is connected to an output port of described touch detection chip U1 by described resistance R 1, pin P21, detects while touching, and the high level signal of pin P21 output is prompting control signal.Other circuit connects with reference to above-mentioned the first embodiment, repeats no more herein.
In prior art, be by an output port, to connect illuminating circuit to carry out luminous prompting.In the present embodiment, with drive circuit and sound circuit combination, substitute illuminating circuit.Original program control does not need to make any change.For example, in prior art, be that an output port connecting luminous diode is anodal, that is to say so when touch action being detected, the output port of this connecting luminous diode output high level, so light-emitting diode carries out luminous prompting.In the present embodiment, on the basis of existing technology, light-emitting diode is removed, the part being connected with output port replace with above-mentioned drive circuit 4 and buzzer, do not need again to fire program and carry out any control change.
The operation principle of the second embodiment is as follows:
When capacitance type touch key is not touched, pin P21 output low level, triode Q1 cut-off, buzzer is not worked.When certain capacitance type touch key is touched, touch touch input port corresponding to detection chip U1 and its capacitance variations detected, pin P21 output high level (realization of this part signal stream is all prior art), so, also conducting of triode Q1, so buzzer carries out sounding reminding.
Although in the second embodiment control procedure less than fast (in prior art of the first embodiment, control program is controlled pin P21 output high level as prompting control signal, the present embodiment makes full use of this point just), but its advantage is, take full advantage of the existing function of prior art, and overall structure is simpler with respect to the first embodiment.
In sum, touch cue circuit of the present utility model and the television set that comprises this touch cue circuit, touched after touch key-press user, can carry out sound prompting by sound circuit.Because sound prompting is more direct, particularly for the elderly, sound prompting is very effective, has effectively overcome the defect that prompting that flashing light exists is missed.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
