Description

Sound selective multiple electronic horn. {Omitted}

The present invention consists of the sound of several horns according to the car type and the newly developed horn sound in the car horn, and the selection and output of the sound are selected according to the ON / OFF setting signal of the horn switch (SW). It relates to a horn sound selective horn that can freely select and run the horn sound desired in the horn of the horn.

The sound of a typical car horn was monotonous and caused excessive noise. In addition, there was a problem in that the second and third horns needed to be mounted according to the type and function of the car, and the sound was attempted by turning ON three times within 1.5 seconds as a means of horn sound switching, but this executed the two-function electronic horn sound. The same error occurs. Other means, such as installing a separate sound switch box or installing a switch for wireless transmission, resulted in economic damage to the car interior and additional mounting.

The present invention is to solve the above problems horn and trombe sound horn according to the car type. COW sound horn. 11 types of horn sounds suitable for the characteristics of each vehicle such as ambulance horn sound are composed, and the sound can be selected and output from one horn, and the sound is different from the normal horn switch ON / OFF time. The switch signal is set and programmed into the CPU. Therefore, the switch signal value is compared and judged by the CPU to operate as a sound change when the set signal is used, and the other switch signal is operated only as the horn sound output, and the malfunction is eliminated by distinguishing it from the 2-function horn sound execution signal. In addition, the horn gate input line is made nonpolar (Patent No. 6635, 49243) (polarity converting unit 100) in mounting on a vehicle, so that it can be connected regardless of the polarity of the vehicle switch wiring, thereby making it suitable for all vehicle types.

Hereinafter, described in detail by the accompanying drawings as follows.

Switch polarity conversion unit 100, signal processing unit CPU 200, frequency generating unit 300, rhythm adjusting unit 400, modulated sound support unit 500, output unit 600 and the mode-specific sound (1) (2) Function electronic horn sound), mode 2 (two functions four steps trombe horn sound), mode 3 (two functions two steps trombe horn sound), mode 4 (electronic sound horn sound), mode 5 (two functions trombe wave horn sound), Mode 6 (twin horn), Mode 7 (six trombe horn), mode 8 (8 rhythm horn), mode 9 (cow horn), mode 10 (boiler horn), mode 11 (ambulance horn) If you touch 3 times (switch ON) once within 0.3 seconds in basic mode 1, the next "Mode 2" is executed, and if you touch 3 times in "Mode 2", "Mode 3" Is executed. When touched three times in "Mode 3", each time it is touched three times in the order of "Mode 5"-"Mode 11" to "Basic Mode 1" in the order that the next "Mode 4" is executed, it is executed in the following operation order. If the touch is made three times once within 0.3 seconds during execution of the above operation, and the switch is ON for more than 1 second without being turned off at the fourth touch, "Basic Mode 1" is executed for 2 seconds, and then 0.5 seconds rested, and then "Mode 2" Is executed for 2 seconds and then rests for 0.5 seconds, then "Mode 4" to "Mode 11" are executed in the order that the next "Mode 3" is executed for 2 seconds, and then "Basic Mode 1" is executed again. "4th touch operation" is executed as "4th touch operation" immediately after touching 4 times in any of the above operation state, the release method is "basic mode 1" state when "touch 3 times" once within 0.3 seconds. Therefore, the ON / OFF signal of the horn switch is set to 1 (3 times in succession once every 0.3 seconds) and 2 (3 consecutive times to turn ON for 2 seconds or more) and 3 (3 times in succession once every 0.3 seconds). Each coded to ON) is programmed to the IC 1 of the CPU 200, and when the horn switch signal is input, the signals are compared at the IC 1 (micro process), and if the setting 1 signal value is set, the basic mode 1 to the next mode 2 order. The sound is switched to, and if the setting 2 signal value, the sound from Mode 1 to Mode 11 is sequentially output for 2 seconds, and when the switch is turned off in the desired mode, the mode sound is selected. If the value of the next setting 3 signal is changed to mode 11 (ambulance car horn sound), it is immediately output as an emergency horn sound.

The termination of mode 11 is reduced to basic mode 1 by the reset 1 signal input, and the generation of sound is selected by IC 1 (micro process) for each type of sound. The IC 2 (C-MOS IC or one-chip process) generates a drive signal according to the rhythm, with 8 independent frequencies in the IC 3, and the sound of noise and goose in the IC 4 (voice assist IC). , Raises the roar of chickens. When the horn switch is pressed, the switch signal voltage is converted into a positive polarity signal by the polarity converting unit 100 regardless of the polarity of the positive and negative polarity, and the gate (IC No. 6 pin) of the IC 1 and the D1 ( Silicon diode) connected to the anode, and the IC 1 is turned on and output as a negative signal for 1 second at pin 1, and the second pin is output as a positive signal for 3 seconds after the gate is turned off. do.

Pins 7, 8, 9, 10, 11, and 12 of the IC 1 are turned on and off in accordance with a set signal, and the cathode of the connected D1 is connected to the photocouplers P3, P4, P5, Each emitter resistor R3, R4, R5, R6, R7, R8 of the photocoupler is connected to the collector of P6, P7, P8 (which can be replaced by three station IC), respectively. Connected in R4 order. The frequency output of the IC (3) is connected to R3 by connecting D5 at pin 8 (416c / s) with a negative square wave, and connected to R4 by connecting D6 at pin 7 (427c / s), number 10 Connect D7 at pin (357c / s) to R5, connect D8 at pin 9 (370c / s) to R6, connect D9 at pin 12 (325c / s) to R7, 11 Connect D10 at pin 341c / s to R8. R3 and R4 are connected to the IC 3 signal sections D5 and D6 and connected to the anodes of D11 and D12. The cathodes of D11 and D12 are connected to R10, and the signals of R10 are amplified by transistors Q1 and Q2 and output to the high sound horn H. R5 and R6 are connected to D7 and D8, and are connected to the anodes of D13 and D14, and the D13 and D14 cathodes are connected to R11, and the R11 signal is output to the midtone horn M by Q3 and Q4. R7 and R8 are connected to D9 and D10 and connected to the anodes of D15 and D16, the cathodes of D15 and D16 are connected to R12, and the signals of R12 are output by the low-pitched sound L by Q5 and Q6. As described above, the operation of each mode is output as high, mid, and low frequencies according to each frequency band.

When the horn is installed in the car and the car horn switch is turned ON, the pin 1 of the IC 1 ((-) potential for 1 second) is connected to the positive pole of the capacitor C1 by mode 1 (two-function electronic horn sound). Pin 2 of IC 2 is positively turned on for 3 seconds after the gate is turned off, and photocouplers P3, P5, and P7 connected to D2, D3, and D4 are turned on. The positive voltages of the resistors R3, R5, and R7 connected to the P3, P5, and P7 are (+) by the pin frequencies 416c / s, 357c / s, and 325c / s of pins 8, 10, and 12 of the IC 3 connected thereto. High frequency (H), middle (M), and low (L) horns are converted to square waves and converted into high-frequency output parts Q1, Q2, and mid-range output parts Q3, Q4 and low-level output parts Q5 and Q6. The horn sound of less than 1 second is grounded by the pin 1 of the IC 1, and the positive pole of the condenser C1 is grounded, and a short horn sound is output. C1 is charged in the OFF state. Therefore, when the horn switch is turned off, the horn sound is generated by R1 connected according to the discharge voltage of C1. In this way, it becomes a two-function electronic horn having a short horn sound and a horn sound remaining. In the next mode, when the horn switch is turned ON with the setting 1 signal, the signal is analyzed in the CPU 200 and the next operation mode 2 is executed.

Mode 2 (2-function 4-stage trombe horn sound) is executed by pin 1 of the IC 1 ((-) voltage for 1 second) connected to the capacitor C1, and C1 is discharged for 1 second. Pin 1 is turned on positively until 3 seconds after gate OFF and P10 connected to pin 7 is momentarily turned on for 0.1 second by the pin 10 clock voltage of the IC 2. The P9 connected to P10 is also turned on momentarily, and the Vcc voltage of the IC 2 becomes negative for 0.1 second by Q7 connected to P9, and the clock signal of the IC 2 is turned off. Therefore, the clock counter is started from 1 to 5, and the counter is turned off by Q7 with the positive of pin 10 on the 5th clock, and repeats 1 to 4 again. With clock 1, pin 3 of IC 2 is turned on for 0.1 second, and the positive (+) signal turned on turns on P3 connected, and R3 connected to P3 is the 8th pin output 416c of frequency generator IC 3. is converted to (+) square wave 416c / s by / s. The sound of 416c / s is output for 0.1 second at the high sound horn (H), and a second 0.1 second clock voltage is generated at pin 2 of the IC 2 in the same order as described above. The clock voltage is output for 0.1 seconds at low horn L by 325c / s connected to P7 ON, and the third 0.1 second clock voltage is again high-pitched by 427c / s connected to P4 ON. In H), sound is output for 0.1 second. Again, the fourth 0.1 second clock voltage outputs a sound for 0.1 second at the low horn L by pin 11 341c / s of the frequency IC 3 connected to the ON of the connected P8. In this way, each different frequency is played as a trombe horn that is output according to the rhythm, and when the horn switch is turned off, the sound gradually decreases during the time when the voltage charged in C1 is dissipated to the bass bias voltage of Q1, Q3, and Q5. It is a horn with disappearing sound. When the switch is turned on for less than 1 second, the positive pole of the capacitor C1 is grounded by pin 1 of the IC 1, and the horn sound is output only as a single sound. Thus, it is a two-function four-stage trombe horn that operates as a horn sound and a short horn sound output in the form of playing according to the rhythm of each sound.

The next mode is mode 3 (two-function two-stage trombe horn) which operates as a two-function two-stage trombe horn sound that outputs two-stage crossover by the connected frequency by interoperating P3 and P7.

Mode 4 (electronic sound horn) simultaneously outputs the frequencies connected to P3, P5, and P7, and outputs the sound of a double horn sound with a sound.

Mode 5 (two function wave sound (world cup cheer rhythm) trombe horn) outputs a positive signal for 0.1 second at pin 2 of IC (1). The signal is output as a wave sound electronic horn sound which simultaneously drives the frequencies connected to P3 and P7 according to the rhythm.

Mode 6 (twin horn) is the frequency of P2, P5, and P7, which is a twin horn sound simultaneously outputted without any noise.

Mode 7 (six trombe horn) turns on each frequency connected to P3, P4, P5, P6, P7, P8 and turns on P12, Q7 connected to the seventh clock on pin 5 of IC (2), according to the rhythm. The six-stage trombe horn, which produces a chord at the frequency of the sound, is output.

Mode 8 (8-stage rhythm electronics) quotes one-time break time when each frequency connected to P3 ~ P8 is operated according to rhythm by turning on P13, Q7 connected to the 8th clock on pin 9 of IC (2). The sound is output as an eight-step rhythm electronic horn that forms harmony.

Mode 9 (cow horn) turns off Q7, IC (2) and IC (3) by IC (1) pin 13 (-) potential, and supports voice 12 pin (-) of IC (1). The earth terminal of the IC 4 is connected. The animal sound signal of the IC 4 (Voice Support IC) is amplified by Q1Q2, Q3Q4 and Q5Q6, and the sound of the soul sound is generated by the high (H), mid (M) and low (L) horns. The sound signal of 4) is divided into the sound of the soul sound, the goose sound, and the sound of the chicken sound, and it can be selected according to the switch change.

Mode 10 (Voyager horn) is a horn that modulated and outputs the signal of the IC 4.

Mode 11 (ambulance horn) crosses each frequency connected to P3 and P7 for about 1 second and is output as an ambulance horn sound. At this time, a pulse of 1.1 c / s is input as a clock signal to IC 14 (C-MOS IC) at pin 17 of the IC 1 at the drive frequency of the counter. Therefore, P11 is turned on by ON for about 1 second of pin 3 of IC 2, ON for 1 second of pin 2 for next second, and ON for next 4 pins of 1 second, and IC 2 is reset by Q7 connected to P11. . Therefore, P3 connected to pin 3 and P7 connected to pin 2 are repeatedly outputted at a frequency of 416c / s and 325c / s in the high and low horn for about 1 second.

As such, it is a useful design that allows the horn sound for each mode to be selected and output by one horn.

The present invention sets a unique signal as a means of sound selection in achieving a purpose by realizing several horn sounds with a pair of horns and systemizing them to be matched according to vehicle types. According to the set signal, various kinds of horn sounds can be selectively output to realize multi-purpose sounds that meet the characteristics of each vehicle, general cars, special cars (disaster cars), ambulance cars, industrial cars, two-wheeled vehicles, yachts and It is possible to have a function as a multi-horn sound output device to suit the horn function of boats and the like. It is possible to freely select and output the horn sound as needed, and to make it easy to mount by activating the horn gate input line, as well as various kinds of horn sounds with one horn without the need to install the horn according to the vehicle application. It can have a function as a multi-horn sound device that can be realized.
