Following conjunction with figs. is introduced element of the present invention and embodiment in detail:
At first see also shown in Figure 2, it is the scheme drawing that connects of the present invention and auto audio equipment, vehicular telephone, the main Handless main body of forming by circuit such as an electronic switch 21, a power supply and charge circuit 22, an amplifier and tonequality treatment circuit 23, source of sound Controlled CPU 24 2, cooperate a signal wire (SW) 3 to form, wherein:
One electronic switch 21 is to be subjected to the triggering of source of sound Controlled CPU 24 and to control loudspeaker 41 sound sources and be auto audio equipment 4 or vehicular telephone 5, and when vehicular telephone 5 incoming calls SELF CL auto audio equipment 4, start auto audio equipment 4 when treating talk-through more automatically;
One power supply and charge circuit 22 provide vehicular telephone 5 suitable power supply and charge power supply, can charge at any time for the battery of vehicular telephone 5;
One amplifier and tonequality treatment circuit 23 with the incoming signal amplification of vehicular telephone 5, use for the pronunciation of rear end output, and eliminate input echo and noise, reduce former sound distortion;
One source of sound Controlled CPU 24, when connecting vehicular telephone 5 and Handless main body 2 for signal wire (SW) 3, the signal voltage of its input source of sound Controlled CPU 24, no matter be HI (A1), LO (A2) or tandem signal (A3) are (as Fig. 3,4, shown in 5) all be made as initial value (being the standby value), and when vehicular telephone 5 output signals when changing (be standby signal) voltage inversion changes (as Fig. 3,4, shown in 5, be that HI (A1) changes LO (B1), LO (A2) changes HI (B2) or the cpu circuit of tandem signal in signal wire (SW) changes for LO or the HI signal exported), promptly export a signal control electronic switch 21, vehicular telephone 5 caller voices are changeed by loudspeaker 41 outputs, and closing automobile sound equipment 4;
One signal wire (SW) 3, but be winding body 31 (seeing also shown in Figure 6) with a suitable length, one end is provided with the vehicular telephone plug 32 of corresponding vehicular telephone 5 signal output sockets, for the signal output socket that is plugged in vehicular telephone 5, plug 32 front ends are provided with the conductor 321 of corresponding vehicular telephone 5 each output point of socket, arrangement by this conductor 321 is inserted point with the various vehicular telephone 5 of correspondence, other end then is provided with one can be for the Signal plug 33 that plugs Handless main body 2, in addition, in the vehicular telephone plug 32, on the circuit of corresponding vehicular telephone 5 voltage standards, it is corresponding with power supply and charge circuit 22 to be provided with a suitable divider resistance, to obtain the suitable supply of vehicular telephone power supply and charging, and the circuit of corresponding vehicular telephone sound standard is provided with one or suitable divider resistance or the electric capacity of a combination and (can adjusts the magnitude of voltage of sound import, and this electric capacity (or resistance) value can be regulated to infinitely great interval by zero), corresponding with amplifying circuit 23 to obtain a suitable sound input value, in addition at no obvious HI, be provided with a cpu circuit in the plug of the vehicular telephone type that LO changes, for judging the tandem signal, and (be about to former tandem signal on behalf of the output action signal, transfer general simple high or low voltage signal to), use for the judgement of rear end.
See also shown in Figure 7, combination by said elements, cooperate auto audio equipment 4 so that the function of Handless to be provided, the sound that Handless main body 2 can be installed on auto audio equipment 4 during use goes out end 43 and automotive acoustic speaker 41, in the middle of 42 and in the middle of auto audio equipment power input 44 and the power supply source 45, with problem (because mounting means and the structure right and wrong emphasis of the present invention place of avoiding installing thereof, so seldom give unnecessary details), see also Fig. 3,4, shown in 5, the signal of terminal output when general vehicular telephone 5 standbies (A) and incoming call (B), be broadly divided into three kinds, first, two kinds is the variation of simple high (A1) low (B1) or low (A2) high (B2) voltage, the third is continuous tandem signal, has only the variation of signal when standby (A3) and incoming call (B3), can install a cpu circuit as differentiation this moment in signal wire (SW) 3, when detecting the tandem signal of standby, cpu circuit is just exported the signal of a LO or HI, to get the tandem signal that substitutes vehicular telephone, if when detecting the tandem signal of incoming call, cpu circuit then can transfer out the substitution signal of HI or LO, therefore with vehicular telephone plug 32 eye-splices of signal wire (SW) 3 after on vehicular telephone 5 signal terminals, when vehicular telephone 5 is gone up in signal wire (SW) 3 connections, the signal of vehicular telephone 5 input source of sound Controlled CPU 24 is no matter be high, low simple voltage (the tandem signal then processing of the cpu circuit in signal wire (SW) also transfers simple high or low voltage to) all is used as initial value (being the standby value), if the signal of the input source of sound Controlled CPU 24 of the signal terminal of vehicular telephone 5 incoming calls, transfer to low by height, low transferring to when high, assert that promptly vehicular telephone is for coming electricity condition, source of sound Controlled CPU 24 is then exported a signal control electronic switch 21, transfer to auto audio equipment 4 quiet or closing automobile sound equipment 4 power supplys, and the input end of automotive acoustic speaker 41 connected Handless main body 2, and caller voice is adjusted by amplifier and tonequality treatment circuit 23, after reducing the call tone quality distortion, play by loudspeaker 41 by the switching of electronic switch 21.After vehicular telephone 5 was finished using, when the standby signal of vehicular telephone 5 was replied initial value, its source of sound Controlled CPU 24 triggered control signal and gives electronic switch 21, will export source of sound and go back to auto audio equipment 4 by amplifier and tonequality treatment circuit 23.
See also shown in Figure 8ly, required circuit (resistance, electric capacity or cpu circuit etc.) in the signal wire (SW) can place separately in the plug 33 of signal wire (SW) 3, or mode that can signal box 34, is connected to 32,33 of two plugs of signal wire (SW) 3.
In sum, of the present invention simple in structure, can be by the judgement of the circuit in the signal wire (SW) (resistance, electric capacity or cpu circuit etc.) processing and source of sound Controlled CPU, solve the decision problem of each the vehicular telephone standby of each factory, incoming call voltage standard fully, and cooperate the Handless main body, when providing vehicular telephone on car, to use, can significantly improve quality and the safety and the comfort feature of conversation, to reach real general-duty purpose, the enhancement on the historical facts or anecdotes tool effect.
