Abstract

The utility model relates to the technical field of a telephone set, particularly a telephone set by which people can listen to station broadcasting programs. The telephone set is composed of a telephone circuit (1), a radio controller (2) and a radio receiver (radio) (3), wherein the input end of the radio controller (2) is connected to the telephone circuit; the output end of the radio controller is connected to the radio receiver. The radio controller is composed of an element or an integrated circuit. The utility model has the advantage that the radio receiver and the telephone circuit are organically combined by the electronic controller, which causes a radio and a telephone to be integrated. When the telephone is called or is used, the radio closes automatically. The radio does not affect the normal operation of the telephone set.

Description

The radio reception telephone set

(1) technical field: the utility model relates to the telephone set technical field, the especially a kind of telephone set that can listen to station broadcast program function that has.

(2) background technology: general telephone set only can be made a phone call, and function singleness if will listen to the station broadcast program, must be purchased broadcast receiver again, except the increase expense, also takies ornament space like this.

(3) summary of the invention: the purpose of this utility model is can listen to station broadcast program function setting in telephone set, makes radio reception, phone integrated, reduces ornament space.

The utility model is made up of telephone circuit, radio reception controller and radio reception receiver (broadcast receiver), and the input of radio reception controller links to each other with telephone circuit, and the output of radio reception controller links to each other with the radio reception receiver.Described radio reception controller can be by element or/and the IC integrated circuit form; Also can be integrated in the same IC sheet with telephone circuit, radio reception receiver; Can also in the IC sheet that contains telephone circuit, radio reception receiver, connect control by program (software).

The utility model, described radio reception controller can be formed by carrying machine testing circuit, ring detecting circuit, anti-jamming circuit and radio reception control circuit, carrying the input of machine testing circuit is connected with the INUSE of telephone set (carrying the machine signal), the input of ring detecting circuit links to each other with the LINE of telephone set (outside line), the output of carrying machine testing circuit and ring detecting circuit links to each other with the input of radio reception control circuit respectively, and the output of radio reception control circuit links to each other with wireless power supply incoming line.

Good effect of the present utility model is to adopt electronic controller that radio reception receiver and telephone circuit are combined, make radio reception, phone is integrated and broadcast receiver does not influence the operate as normal of telephone set, reduce placing space, thereby realize resource-sharing, increase the added value of telephone set.

(4) description of drawings: Fig. 1 is an electric functional-block diagram of the present utility model; Fig. 2 is the electric functional-block diagram of the radio reception controller of embodiment 1; Fig. 3-Fig. 5 is the electrical schematic diagram of embodiment 1, and wherein: Fig. 3 is a phone part electrical schematic diagram, and Fig. 4 is the electrical schematic diagram of radio reception controller, and Fig. 5 is the electrical schematic diagram of radio reception receiver (broadcast receiver); Fig. 6 is the electrical schematic diagram of embodiment 2 radio reception controllers.

Among the figure, 1, telephone circuit 2, radio reception controller 3, radio reception receiver (broadcast receiver) 21, carry machine testing circuit 22, ring detecting circuit 23, anti-jamming circuit 24, radio reception control circuit 25, broadcast receiver power supply incoming line.

(5) embodiment: embodiment 1, with reference to Fig. 1-Fig. 5, this example is made up of telephone circuit 1, radio reception controller 2 and radio reception receiver (broadcast receiver) 3.Telephone circuit and radio reception receiver do not have specific (special) requirements, and telephone circuit shown in Figure 3 is the plain old telephone machine circuit, and radio reception acceptor circuit shown in Figure 5 is common receiver circuit.Radio reception controller 2 is formed by carrying machine testing circuit 21, ring detecting circuit 22, anti-jamming circuit 23 and radio reception control circuit 24.Carry machine testing circuit 21 by resistance CR ₁With diode CD ₁Be composed in series, ring detecting circuit 22 is by capacitor C C ₁, CC ₂, the sub-CD of bridge rectifier ₅-CD ₈With resistance CR ₂, CR ₄Form; Anti-jamming circuit 23 is by capacitor C C ₃, resistance CR ₃Form; Carrying the input of machine testing circuit is connected with the INUSE of telephone set (carrying the machine signal), the input of ring detecting circuit links to each other with the LINE of telephone set (outside line), and the output of carrying machine testing circuit and ring detecting circuit links to each other with the input of radio reception control circuit respectively; Radio reception control circuit 24 is by transistor CQ ₁, CQ ₂, CQ ₃, capacitor C C ₄, CC ₅, resistance CR ₅-CR ₇Form CQ ₁Base stage respectively with CD ₁And CR ₄Link to each other CQ ₁Collector series connection CR ₆Afterwards and CQ ₂Base stage link to each other CQ ₂Collector electrode and CQ ₃Base stage link to each other, the output of radio reception control circuit is CQ ₃Collector and emitter be serially connected with broadcast receiver power input line road.The model and the parameter of selected each components and parts of this example are marked in the electrical schematic diagram.

The operation principle of radio reception controller is as follows: under the normal ideal case of telephone set, the radio reception receiver is by control switch K ₁Control is as Closing Switch K ₁The time just can listen to program of radio station (cooperate with program by-pass cock) because the CQ in the radio reception this moment control circuit ₁Base stage is an electronegative potential, CQ ₁End CQ ₂, CQ ₃Be conducting, CQ ₃Wireless power supply is connected in conducting; When broadcast receiver in normal operation, when outside line has phone to squeeze into, by CC ₁, CC ₂, CD ₅-CD ₈, CR ₂The testing circuit that constitutes detects bell signal through CC ₃, CR ₃Deliver to radio reception control circuit CQ after the filtering ₁Base stage, make its conducting, CQ ₂End CQ ₃Base stage is a high potential, CQ ₃Also end simultaneously, cut off the broadcast receiver power supply, in order to avoid broadcast receiver disturbs outside line to squeeze into; When broadcast receiver in normal operation, if this telephone set is when carrying machine, INUSE (carrying the machine signal) is in high potential, carries machine testing circuit CR ₁, CD ₁To carry the machine signal and deliver to CQ ₁Base stage, CQ ₁Conducting, CQ ₂End CQ ₃Also end, cut off the broadcast receiver power supply, in order to avoid broadcast receiver disturbs this telephone set and outside line conversation; When the tinkle of bells stops or this machine radio reception controller of finishing using after the on-hook will be delayed time and be turned on broadcast receiver automatically behind the certain hour, the time of time-delay is by delay circuit CR ₅, CC ₄Decision; If want to close broadcast receiver, only need close broadcast receiver mains switch K ₁Get final product.

Embodiment 2, with reference to Fig. 6, this example is on the basis of embodiment 1, the CQ in radio reception control circuit 24 ₃Collector and emitter paralleling switch K ₂,, then only need K switch if want coming bell or making the telephonic broadcast receiver that uses simultaneously ₂Closed getting final product.All the other are all identical with embodiment 1, no longer repeat.
