Description

A kind of automobile multitone horn

Technical field

The utility model relates to automotive field, is specifically related to a kind of automobile multitone horn.

Background technology

Present motor vehicle loudspeaker is made up of loudspeaker and bass horn, its dull sound is turned a blind eye to and is disliked by the pedestrian already, substantially can not adapt to the requirement of geographical environment, horn-blowing control is carried out in many highway sections in the arterial street, original compound horn be owing to can not regulate volume, do not reach requirement on environmental protection and do not allow to use; Can not satisfy simultaneously modern's individual demand, though the motor vehicle that has has used voice or music alerting pattern when reversing, but it can not play a role in the motor vehicle cruising, and its sound dullness, there is not more washability, and can not send loudspeaker according to the crowd of all ages and classes, can not embody civilized society driver's individual quality and courtesy with courtesy.

Summary of the invention

The purpose of this utility model provides a kind of automobile multitone horn, and these loudspeaker have multiple sound equipment, can play different tuckets at different crowd, and the personalized sound is arranged.

A kind of automobile multitone horn, comprise button bell sound selected control device and receive controller, button bell sound selected control device comprises single-chip microcomputer, be electrically connected on the input circuit of single-chip microcomputer input end, be electrically connected on the radiating circuit of single-chip microcomputer output terminal, be electrically connected on the button inputting circuits of single-chip microcomputer input end, be electrically connected on the power-saving control circuit of single-chip microcomputer; Receive controller, be electrically connected and form by wireless receiving circuit, single-chip microcomputer, language chip circuit, audio frequency effect circuit, loudspeaker successively.

The single-chip microcomputer of button bell sound selected control device also is electrically connected with emission indicating circuit, low pressure indicating circuit, power-saving control circuit.

Wherein the button input circuit is three to take advantage of four matrix form flexible circuit plates, also can be four and takes advantage of four matrix form circuit boards.

The button input circuit is located on the bearing circle, which is provided with a plurality of key contacts, can produce different sound equipments by each key contacts.

About loudspeaker can be made as two.

These loudspeaker have multiple sound equipment, can play different tuckets conveniently at different crowd, and the personalized sound is arranged, and for wireless connections, easy for installation.
