Touch type horn system with counting function

Abstract

The invention relates to the field of acoustic equipment, in particular to a touch type horn system with a counting function. The invention overcomes the defects of short service life, unstable quality, old-fashioned appearance and single sound of a conventional automotive horn, and provides a horn system with long service life, stable quality, novel appearance and rich sounds. The horn system comprises a controller, contact horns, a horn trigger line, an althorn line and a sackbut line, wherein the number of the horn contacts is two, one of the horn contacts is connected with the controller through the althorn line, and the other horn contact is connected with the controller through the sackbut line, the horn trigger line is connected to the controller, the controller is provided with a sound type switching key for the counting display and nixie tubes for the sound types, and the use times and the sound type can be stored during power failure. The invention has reasonable design, obvious effects and wide application range.

Description

Technical field [0001] The present invention relates to the field of audio equipment, and in particular to contact-type horn equipment. Background technique [0002] At present, the relays of car horns have coil contacts and static iron core structures. The relay contact generates a magnetic field (electromagnetic force) through the coil, the contact is closed once, and the horn buzzes once. The product manufactured by this mechanical conversion design method has a short service life, unstable quality, and often burns out and does not work. , When the horn is in good condition, the relay does not work normally and cannot protect the horn, thus shortening the working life of the horn, and because of its structural defects, the appearance is not novel, and the frequency is extremely unstable after the contacts are affected by moisture. , Causing the speaker to not work and bring many difficulties, and it can only work with a single sound, and cannot change the sound of the speaker...
