Abstract

The utility model discloses a multifunction electronic horn which is an up-to-date electronic horn used for cars and motorcycles, composed of an electronic sounding part (1), an electronic audio amplification part (2), an electronic power amplification part (3) and a loudspeaker (4). The utility model has the functions of the playing of horn sound and music sound and the implementation of loudspeaking. Because the electric imitation sound is used for replacing the contact lighting sounding, the utility model has the advantages of complete functions, little power consumption, long service life, less investment and obvious effect.

Description

Multifunction electronic wind instrument

The utility model is the electronic horn sound device that a kind of automobile, motorcycle are used, this device is made up of electronic sound part (1), audio frequency amplifier section (2), power amplifying part (3), loud speaker (4), has the function that tucket, music sound, enforcement are propagandaed directed to communicate and amplified.

Traditional motor vehicle " electric horn " all is the electromagnetic contact formula, by the contact sparking, makes electromagnet produce intermittently magnetic field, and causes the vibration of elasticity iron plate, thereby send the loudspeaker sound.---noiseless, or cause the contact adhesion---short circuit and burn circuit that damage is easily hit in its contact, and the spark ashes remain in contact surface, causes loose contact.

The purpose of this utility model provides a kind of motor vehicle bicycle electronic horn of update, adopts electronic simulation sound to substitute traditional contact sparking sounding, and it can effectively overcome above-mentioned shortcoming.

Below in conjunction with Fig. 1 embodiment of the present utility model is described:

By electronic music integrated package (IC ₁) send the audio signal of simulating tucket, amplify through electronics amplifying circuit (in the frame of broken lines), again through R ₁, C ₁Be defeated by electronic power amplifier integrated block (IC after the coupling ₃), IC ₃The audio signal that has increased power is coupled voluntarily, mates and be defeated by loud speaker and send clear and melodious loud and clear tucket.IC ₂Be music-integrating block, MIC is the piezoceramics crystal microphone, by knob K ₁Enforcement is to tucket, music sound, the selection of propagandaing directed to communicate.C ₂(47uF), C ₃(470uF) be anti-surge capacity, C ₄(0.IuF), R ₄(47 Ω) and C ₅(0.1uF), R ₆(47 Ω) is speaker protection circuit, C ₆(10uF), C ₇(0.IuF) be filter capacitor, D ₁(IN5408) protection entire circuit.AN is a button, K ₂Be the motor turning lamp switch; K ₂When the button handle was got meta, entire circuit was closed down; K ₂When swinging to 1, without the button control sound equipment; K ₂When the button handle is swung to 2, through the button control sound equipment.When the 6V powered battery, R ₂, R ₃Be respectively 70 Ω, 150 Ω; When the 12V powered battery, R ₂, R ₃Be respectively 300 Ω, 500 Ω.

Compare with tradition " electric horn ", the utility model has following advantage: 1, function is complete; 2, little power consumption; 3, the life-span is long; 4, the sorrow of no short circuit; 5, small investment, instant effect.

" electronic sound " part of Fig. 2, the i.e. IC of Fig. 1 ₁, IC ₂, MIC, be respectively tucket integrated package LH-9300, music-integrating block LH-9300, piezoceramics crystal microphone." audio frequency amplification " part of Fig. 2 is made of the element in Fig. 1 frame of broken lines; Triode 9013,47K potentiometer R ₁, resistance R ₆, R ₇, R ₈Be respectively 1K, 150K, 1K, capacitor C ₁, C ₈, C ₉, C ₁₀Be respectively 3.3uF, 2000P, 47uF, 3.3uF." power amplification " part of Fig. 2, the i.e. IC of Fig. 1 ₃, be double power amplifier integrated package KD-28." loud speaker " of Fig. 2, the i.e. Y of Fig. 1; When power supply DC was 6V, Y was 4 Ω 3W; When power supply DC was 12V, Y was 4 Ω 15W.

The utility model implementary value is big, and economic benefit is very remarkable.Product is widely used on the vehicles such as automobile, motorcycle, bicycle, also can be supporting with toy for children.

Claims

A kind of motor vehicle of update, the electronic horn of bicycle use, adopt electronic simulation sound to substitute traditional contact sparking sounding, it is characterized in that forming by electronic sound part, audio frequency amplifier section, power amplifying part, loud speaker, send the audio signal of simulation tucket by the electronic music integrated package, after the amplification of electronics amplifying circuit, promote loud speaker through the amplification of power amplification integrated package again and send clear and melodious loud and clear tucket.
