Acousto-optic amplifying functions are added at the same time for reminding the user of the incoming call, and therefore the aim of preventing the problem that an important call is missed can be realized.
Description
Technical field
The utility model relates to a kind of phone, and is particularly a kind of simultaneously with the phone of acousto-optic sound amplification function.
Background technology
In some particular application, as complicated in common application field settings such as elevator, railway, highway, mine, subways, particularly noise intensity is high, if common incoming ring tone callee often misses the risk of incoming call, make the caller can't in time find the callee, thereby affected the transmission of related emergency information.Summary of the invention
Key in herein summary of the invention and describe paragraph.
The utility model content
Technical problem to be solved in the utility model is how to increase or to strengthen the call reminding mode and come reminding user that phone has been arranged, and shortens the response time, and reduces the user misses important incoming call in complex environment risk.
In order to solve the problems of the technologies described above, the utility model has designed a kind of acousto-optic hands free telephone, comprise that the modules such as MCU, busy tone detecting, the tinkle of bells circuit, the tinkle of bells that amplifies, the tinkle of bells detection, power switch circuit, speaking circuit, power amplifier, the tinkle of bells or microphone signal selection circuit, warning lamp, automatic hand-up auto-pickup, MIC, power supply form, and is characterized in that:
Described the tinkle of bells or microphone signal select circuit to be connected with described speaking circuit with the described the tinkle of bells that amplifies respectively by gating switch, be connected with described power amplifier, and be connected with described MCU, described gating switch is controlled by described MCU to select described the tinkle of bells or the described speaking circuit of amplifying to be connected with described power amplifier;
When described warning lamp has detected incoming call at described the tinkle of bells detection module, controlled by MCU and begin flicker work, reminding user has incoming call;
Described automatic hand-up auto-pickup module is connected with described power switch circuit with MCU, and when MCU monitors incoming call at T when second, all nobody replied, MCU controls described power switch circuit and switches on power, the automatic connecting incoming call of described automatic hand-up auto-pickup module.
Described acousto-optic hands free telephone characterized by further comprising the elimination talk-back circuit.
By increase amplify the tinkle of bells, overtime automatic connection and to call voice amplify design and increase the modes such as incoming call alarm lamp flicker simultaneously multi-faceted reminding users incoming call is arranged, avoid to greatest extent the user and missed the possibility of important incoming call because be not careful, the processing that amplifies that the call voice of sending a telegram here simultaneously increases, also solve simultaneously technical problem that can't not hear calling voice when ambient noise is too large, enlarged the application scenario of this phone.
Description of drawings
Fig. 1 is the telephone system block diagram of acousto-optic hands free telephone.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only 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 obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the telephone system block diagram of acousto-optic hands free telephone, and the groundwork principle is as follows:
When the tinkle of bells detection module detects the phone inlet wire incoming call is arranged, the tinkle of bells detection module is given MCU with incoming telephone signal, and MCU controls power module at once and switches on power to power amplifier, and switches on power for the tinkle of bells circuit, send incoming ring tone, control simultaneously sound circuit and produce the tinkle of bells that amplifies; MCU controls tinkling of pieces of jade sound or microphone signal and selects the module gating the tinkle of bells that amplifies, and the power amplifier module is amplified the tinkle of bells and the tinkle of bells that amplifies being broadcasted away by loudspeaker of amplifying; MCU controls the power supply supply of opening warning lamp simultaneously, makes lamp begin flicker work, and reminding user has incoming call; Realize reminding the function of sending a telegram here by amplify broadcasting and light simultaneously.
In order further to improve this function, consider the people generally to oneself the acoustic information of name all than other sound sensitive, the utility model and then designed to play when the tinkle of bells that amplifies and reach the number of times that presets or time T after second, ring unanswered also, MCU controls power switch circuit, switch on power, the automatic connecting incoming call of automatic hand-up auto-pickup module; MCU controls tinkling of pieces of jade sound or electric signal and the power amplifier connection in the future of microphone signal selection circuit gating speaking circuit simultaneously, and the sound of calling personnel can amplify the caller voice signal by power amplifier, and by loudspeaker, the caller voice signal is broadcasted away.The personnel of calling can realize directly calling the people's that will look for name or directly the information exchange mistake that will pass on.
When realization amplified, MCU output was controlled and is eliminated the input that talk-back circuit turn-offs MIC, avoided generation to utter long and high-pitched sounds.Eliminate talk-back circuit and be made of two PNP triode Q9 and Q6, wherein play the e utmost point ground connection of Q9, the b utmost point of Q9 is connected with the MCU control port, and the c utmost point of Q9 connects and draws resistance to meet VCC and be connected with the b utmost point of Q6; The e of Q6 extremely is connected with the input of MIC, and the c utmost point of Q6 is connected by the speaking circuit of electric capacity with phone.MCU controls the Q9 conducting by the output high level, and the Q6 cut-off makes MIC obtain power supply when amplifying and can't work, and reaches the purpose that consumes echo.
After the other side's on-hook, the busy tone detection module of this telephone set can detect busy tone, automatic hand-up, and microprocessor can hang up the power supply of hands free telephone part, the part circuit that amplifies is quit work, and the power supply of turn-off lamp supplied with.
This telephone set has also been done dial-up circuit, can number of rings is set and dial phone number by dial, carries out usual telephonic communication.
Above disclosed is only a kind of embodiment of the utility model, certainly can not limit with this interest field of the utility model, one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment, and according to the equivalent variations that the utility model claim is done, still belong to the scope that utility model contains.
