The purpose of this utility model is, based on prior remote controller, connect conventional TV audio receiving circuit and electric time-keeping circuit, a kind of regularly open and close function that both had is provided, can control again, the multi-functional TV set remote-controller of conversion TV sets sound accompaniment receive mode, to overcome the deficiencies in the prior art.

Overall structure of the present utility model is:

Circuit on the central layer connects clock control circuit unit (1) and sound accompaniment receiving circuit unit (5) based on the infrared remote controller unit (3) of routine; Its clock control circuit unit is on the acoustics circuit a of conventional electrical timing IC chip, b end, the input C and the power supply E that connect the transistor delay circuit respectively constitute, the output d of clock control circuit, going between with the coding of launching code device by photoelectrical coupler (2) and conventional infrared remote control connects; Conventional one-chip television sound accompaniment receiving circuit unit (5) connects with remote control circuit unit (3) by power supply (4);

The conversion of the function of clock control circuit unit, give contact leads such as the time of putting and time adjusting and connect with push-button switch N, A, T on the telecontrol panel respectively; The output of sound accompaniment receiving circuit unit (5) lead-in wire connects with earphone socket K on the box body, on telecontrol panel also by adorning " earphone-loud speaker " conversion keys A ', on ﹠ off switch DN and time display S.

The draw bail of remote control circuit is:

Based on KS5803 launching code device, constitute conventional remote control circuit unit (3); The clock control circuit unit is to connect conventional transistor delay circuit to constitute on " newspaper makes a noise " circuit of the electronic watch chip with timing function, and its input C is transistor BG ₁Base stage, output d be transistor BG ₄Collector electrode, photoelectrical coupler adopts the IC sheet (N) of conduction impedance less than 300 Ω, its output connects with 3 pin, the 14 pin lead-in wire of KS5803 respectively, the IC sheet of sound accompaniment receiving circuit unit (5) is the TDA7021IC sheet, its 12 pin passes through capacitor C ₁₃Respectively with power supply and earphone socket on corresponding terminals link, the N on the telecontrol panel, A, T key and time display S are corresponding device thereof on the electronic watch core, on the panel contact of DN key, A ' key respectively with 3 pin of KS5803,4,14 pin lead-in wire connects.

Adopt 12 function electronic watch core circuits to connect with transistor BG ₁, BG ₂, BG ₃, BG ₄Be that main delay circuit constitutes the clock control circuit unit, N is the 4N25 photoelectrical coupler, its 1 pin and BG ₄Collector electrode connect, 5 pin, 6 pin connect with 3 pin, 14 pin of KS5803 respectively.

Accompanying drawing of the present utility model has:

Fig. 1 is the circuit structure diagram on the remote controller central layer.

Fig. 2 is the panel layout of remote controller.

Accompanying drawing has provided embodiment of the present utility model, in conjunction with the accompanying drawings it is further specified as follows:

1, clock timed power on/off function:

The electronic watch core that " newspaper makes a noise " function is arranged regularly by harness on central layer.Owing to connected with BG ₁, BG ₂, BG ₃, BG ₄Be main transistor delay circuit, by capacitor C ₁, C ₂The charge and discharge effect make BG ₂, BG ₃Conducting or end, timing electric pulse signal with the output of electronic watch core warning circuit, export remote control to the KS5803 encoder in the infrared emission circuit by photoelectric coupled device N, and emission infrared remote-controlled signal, after device reception supporting in the television set, make television set open and close automatically in the time that electronic watch core sets with it.

During use, remote controller must be placed in the control range of receiving system in the television set.In addition, have only when television set is in the remote-control closedown state, could utilize remote controller to implement timing start-up.

The time of putting and the corresponding attaching of time adjusting button are changed, given to N on the telecontrol panel, A, T key with the function of electronic watch core, and the time display S on the panel is the LCD of electronic watch core.BG ₁, BG ₃Can adopt 3DG6～8 or 3DK ₂Model, BG ₂, BG ₄Be 3CG ₁₄The triode of model.

2, the control transformation function of sound accompaniment reception:

The frequency modulation sound accompaniment emitter that sound accompaniment output attaching in television set matches with the utility model.At three ends or five terminal jack (K) the interpolation lug machine of remote controller, and press A ' key on the panel, TV loudspeaker is quit work, can realize utilizing the sound accompaniment receiving circuit on the remote controller central layer to listen to television field frame."+" on the panel, "-" button are used to regulate volume, press the sound accompaniment that each channel switching key "-"～"+-" can receive different television channels.A ' key on the panel is the switch of sound accompaniment emission, and the operating frequency of this monolithic sound accompaniment receiving circuit is 88-108NHZ.
