Abstract
The present invention relates to a peripheral equipment control circuit for a radio telephone, particularly to a circuit which can identify whether the radio telephone is used and control peripheral equipment. An antenna, which inducts electromagnetic waves emitted from the radio telephone, is arranged on the control circuit. The electromagnetic waves become current on the circuit, and after the current is treated by a wave detector, a weak electric potential difference is obtained. The electrical potential difference is amplified by a voltage amplifier to become driving voltage, and thereby, the peripheral equipment, such as automatic switches of earpiece without hand-held audio amplifiers, ring warning devices of ear pieces, automatic controllers of telephone answering machines, etc., is controlled.
Description
Whether the present invention is relevant a kind of dialogue device peripheral equipment control circuit, refer to a kind of electromagnetic wave of picking up the emission of dialogue device especially and differentiate the dialogue device and using, and then control the circuit of its peripheral equipment.
(for example: use mobile phone) is along with the progress of human civilization is popularized day by day for radio, right itself in use, still there are some shortcomings, when for example using onboard, because the hand microphone communication is easy to generate danger, so produced handfree receiver unit, though yet the handfree receiver unit of commonly using can reach certain effect, but when the dialogue device is in holding state, when avoiding closing of the circuit to use, go to open the power supply of handfree receiver unit again and cause some inconvenience and danger, the singing of the stream that the sound amplifying circuit of general Handless and loudspeaker produce has suitable volume usually, thereby the puzzlement driver; And, because the mobile phone user increases day by day, when participate in a conference, cinema, music hall or in other public arenas, the irritating jingle bell sound evil of often making a nuisance of oneself, therefore, how overcoming this problem also is an important topic; As GB, disclosed content in 2224183 and EP, 529798.Again,,, can influence its operation, therefore usually it is seated near somewhere, but when electric bell rings, can't hear if usually carry because mobile phone is heavy for some engineering construction persons ... or the like.
The object of the present invention is to provide a kind of dialogue device peripheral equipment control circuit, whether using in order to differentiate message register, thereby correspondingly its peripheral equipment is being controlled.
General dialogue device (for example mobile phone), transmit when being the signal of machine when receiving base station, promptly emission one high-power signal is given the usefulness of base station as two-way communication automatically, holding state does not promptly have this send action at ordinary times, based on this phenomenon, the present invention designs a kind of control circuit, and whether the someone is machine to differentiate radio telephone, whether just in use, or not at holding state.
Whether a kind of dialogue device of the present invention peripheral equipment control circuit is used to differentiate this radio telephone and uses, and its characteristics are:
Be equiped with an antenna on this control circuit, induction is by the electromagnetic wave of radiophone ejaculation, and this antenna is connected to an end of diode detector, and the other end of this diode detector is held with being connected to; Described antenna links to each other with the input of a voltage amplifier with the contact of diode detector, and the electromagnetic wave signal of being responded to is amplified, and the output of this voltage amplifier links to each other with the peripheral equipment of described dialogue device, so that it is controlled.
Below, be described with reference to the accompanying drawings the embodiment of the invention.
Description of drawings
Fig. 1 is a circuit diagram of the present invention.
Fig. 2 is the another embodiment of the present invention circuit diagram.
Fig. 3 is the another embodiment of the present invention circuit diagram.
Accompanying drawing 1 is an a kind of embodiment of dialogue device Handless sound intensifier automatic switch, mainly be on this control circuit the installing one antenna 10 (this antenna 10 can be metal bar, coil, lead, also can be directly replace) with the pin of Copper Foil on the circuit board or element, make it to respond to the electromagnetic wave of launching by the dialogue device, after antenna 10 is sensed electromagnetic wave, the two ends of antenna 10 promptly can produce the voltage difference that constantly changes back and forth, because these voltage differences are an exchange status, and positive negative value is rough to be equated, so the average potential that is produced still is zero potential.This antenna 10 is connected to an end 22 of a diode 20, and the other end 21 of this diode 20 is held COM with being connected to, because diode 20 only can unidirectional conducting, so when antenna 10 tops hold COM to be negative potential over the ground, the electric current of ground end COM just can flow through this diode 20, and this 0 current potential of locating promptly remains near on the zero potential, when COM is positive potential over the ground on antenna 10 tops, electric current can't be held COM with flowing to, and this 0 average voltage of locating is about 1/2nd positive voltage, that is when this antenna 10 is sensed electromagnetic wave, locate just to have a voltage to produce at this 0, though obtained positive voltage is very faint, but amplification through a voltage amplifier 30, just can form an enough big voltage, again with this driven one switch 40, power pin 51 or voice signal that this switch 40 is connected in the sound signal amplifier 50 of dialogue device Handless sound intensifier input or output end, and whether control connection that this power pin 51 or voice signal input or output end, in running order with the sound signal amplifier 50 that makes this dialogue device Handless sound intensifier, because of dialogue device launching electromagnetic wave constantly when connecting phone, so even this sound signal amplifier 50 of this circuit keeps operating state, but if behind the end of conversation, that is the dialogue device is replied holding state and during acomia radio magnetic wave, this antenna 10 does not just have electromagnetic wave and receives, and the current potential that this circuit is obtained promptly disappears, therefore this switch 40 returns back to open-circuit condition, and the Handless loudspeaker are voiceless sound output.
Aforesaid control circuit, the circuit by antenna 10, diode 20, voltage amplifier 30 and switch 40 are formed can make it reach quiet release manual operation, and guarantee convenience, safety.
Figure 2 shows that another embodiment, output 31 at the voltage amplifier 30 of aforementioned control circuit connects a reflector 60, when the dialogue device in use, as previously mentioned, output 31 at amplifier 30 produces a voltage to start 60 one signals of reflector, after the receiver 70 through carrying receives, is machine attention device 80 (vibrating motor, sound or luminous etc.) with control, make when mobile phone can't be carried because of work relationship, in certain distance, can examine and know that phone is in machine.
Fig. 3 is another embodiment, the output 31 of voltage amplifier 30 directly connects and is machine attention device (vibration, sound or luminous etc.) or telephone answering and recording machine controller 90, when the dialogue device receives, produce voltage output at voltage amplifier 30 outputs 31 as previously mentioned, directly be machine attention device or telephone answering and recording machine controller 90 in order to control, do not disturb other people so that in short distance, realize quiet reception (mobile phone is by quiet), but but the phone of perception simultaneously has the people to be machine, or the may command answer phone is done the action of open and close.
