Permanent magnet 4 is installed in the coil brace 8.Gapped between permanent magnet 4 and coil brace 8, on coil brace 8, be wound with coil 7, coil brace 8 adopts copper, aluminium, iron, stainless steel, alloy or compound substance.By the interaction between permanent magnet 4 and the electromagnetic field, formed a kind of new sound-producing device.Interaction between permanent magnet 4 and the electromagnetic field is finished by coil brace 8 and coil 7 by permanent magnet 4.Be provided with shell fragment bearing support 14 on pedestal 5, be connected with two high-power MOS tubes respectively at shell fragment bearing support 14 two ends, projection is connected with connecting link 6 by shell fragment 13 in the middle of shell fragment bearing support 14, and fixing with permanent magnet nut 15.Semicircle plastic circuit board supporting member 12 is set on pedestal 5, and the screw that pilot hole and fixing circuit board 11 are set in the above is a plurality of.In circuit board supporting member 12, be provided with a plurality of circuit board fixed orifices, circuit control panel 11 is installed in the circuit board supporting member 12, and be connected with coil 7 with power lead 20 respectively with line.Be provided with upper plastic cover 18 in the top of pedestal 5, upper plastic cover 18 links to each other with snail type housing 1, is provided with a plurality of fairleads in the outside of upper plastic cover 18, and on horn 16 horn protective cover 17 is set, horn bracket 19 1 ends are connected with snail type housing 1, and the other end is fixed on the automobile.
Connect in a usual manner between the above loudspeaker parts.Wherein, in the utility model, circuit control panel 11 refers in particular to a horn circuit control system.As shown in Figure 2, it mainly is made of single-chip computer control system 21, stabilized voltage supply 22, input circuit system 23, horn button 24, output circuit system 25, bass level translation drive system 26 and high pitch level translation drive system 27.The alternative sounds that multitone horn produces is to be produced by Single Chip Microcomputer (SCM) system 21 controls, and is communicated with realization with horn button 24 on the vehicle steering.Wherein, stabilized voltage supply 22 gives Single Chip Microcomputer (SCM) system 21 power supplies, the signal of horn button 24 is connected with Single Chip Microcomputer (SCM) system 21 by input circuit system 23, horn button 24 not only can be connected with positive source but also can be connected with power cathode, pass through control high pitch level translation drive system 27 and bass level translation drive system 26 by Single Chip Microcomputer (SCM) system 21, export high and low sound two paths of signals, be connected with loudspeaker 29, bass horn 28 through output circuit system 25 respectively, make the sent high pitch of paired use and the multitone car horn of bass synaeresis.The utility model also can only adopt an output circuit system 25, and matching design has the Single Chip Microcomputer (SCM) system 21 of corresponding program, makes the car horn that sends multiple sound that loudspeaker are only arranged.
Horn button 24 is arranged on the vehicle steering, and as the control knob of voice signal, itself is also as switch conduction input circuit system, and as shown in Figure 3, stabilized voltage supply 22 is through resistance R 1And R 2After the dividing potential drop, export a 6V signal, again through diode D 1To D 4Rectification, the signal after the rectification is delivered to Single Chip Microcomputer (SCM) system 21 by photoelectrical coupler IC.When car horn button 24 was pressed (negative or positive electrode of another termination power of horn button 24 all can), this circuit produced a signal and gives Single Chip Microcomputer (SCM) system 21, and Single Chip Microcomputer (SCM) system 21 is made corresponding processing according to the variation of this signal.Then, Single Chip Microcomputer (SCM) system 21 is again to bass level translation drive system 26 and high pitch level translation drive system 27 output two paths of signals, and bass horn 28, loudspeaker 29 by being connected with bass, high pitch level translation drive system 26,27, produce the various sound of bass, high pitch or synaeresis, and have the good characteristic of tonequality.
As shown in Figure 3, also be connected with a quartz crystal signal source Y on the Single Chip Microcomputer (SCM) system 21, it can make the output signal frequency of Single Chip Microcomputer (SCM) system 21 very stable, thereby makes the frequency stabilization of loudspeaker, tone color melodized.Output circuit system 25 adopts the bi-directional drive mode, as shown in Figure 4, bass level translation drive system 26 is connected an output circuit system 25 respectively with high pitch level translation drive system 27, output circuit system 25 forms the driving circuit of push pull mode work by NMOS power tube PMOS power tube in parallel, but makes all two-way operations of bass horn coil L1 and loudspeaker coil L2.Because the driving circuit of push pull mode work requires dual power supply, and the power supply on the automobile is a single supply, but in order to make bass horn coil L1 and loudspeaker coil L2 two-way operation, the utility model two capacitor C of between the PMOS of Circuits System 25 power tube and NMOS power tube, connecting 1And C 2(C 3And C 4Effect identical), realized the working method of dual power supply.
Output circuit system 25 also can adopt unidirectional drive mode as shown in Figure 5, only connect bass horn coil L1 or loudspeaker coil L2 with a NMOS power tube or a PMOS power tube, make the horn coil one-way only operation, make and to send bass, high pitch or synaeresis, but have different timbres in the car horn of the multiple sound of bi-directional drive.Certainly, the utility model also can adopt other existing output circuit system.
Car horn button 24 of the present utility model can be set the signal that sends kind of alternative sounds surplus in the of 20, and is corresponding, the corresponding signal of kind surplus Single Chip Microcomputer (SCM) system 21 is arranged to handle 20.As shown in Figure 6, when car horn button 24 sends a certain signal input Single Chip Microcomputer (SCM) system 21, program start, through numerical evaluation and judgement, program is exported a respective signal, and signal outputed to bass level translation drive system 26 and high pitch level translation drive system 27, and be connected with bass horn 28 or loudspeaker 29, corresponding sound produced.When pressing horn button 24, be that single loudspeaker or two loudspeaker all send first kind of sound, if uninterruptedly pin 3～5 seconds of horn button continuously, loudspeaker can pipe continuously and be replaced by second kind of sound automatically after 3～5 seconds, return first kind of sound behind the 20 kind of sound.As long as before not changing sound, unclamp horn button 24, will automatically lock this sound.
In sum, that multitone horn provided by the utility model has is contactless, tonequality good, moisture proof, heatproof are wide, little power consumption, long service life, need not external any device, characteristics such as sound in surplus on various car horn buttons, can setting 20, but on widespread use and the various automobile, to be suitable for the function of loudspeaker under the different occasions.
