Description

Novel motor vehicle horn device

Technical Field

The utility model belongs to motor vehicle loudspeaker field, concretely relates to motor vehicle loudspeaker device through bluetooth agreement broadcast audio frequency.

Background

The prior known motor vehicle horn is divided into an air horn and an electric horn according to sound power; the shape of the device is divided into three types, namely a cylinder shape, a spiral shape and a basin shape; the loudspeaker is divided into a high pitch loudspeaker and a low pitch loudspeaker according to the sound production frequency. The traditional automobile electric horn is used for generating sound by vibration of a metal diaphragm. The electric horn for automobile consists of iron core, magnetic coil, contact, armature, diaphragm, etc. When a driver presses a horn switch, current passes through a coil through a contact, the coil generates magnetic force to suck down a self armature, the diaphragm is forced to move, the armature moves to disconnect the contact, the current is interrupted, the magnetic force of the coil disappears, and the diaphragm and the armature recover to the original position under the action of the elasticity of the diaphragm and a spring piece. The contact closing circuit is again turned on, and current flows through the coil through the contacts to generate magnetic force, and the above actions are repeated. The diaphragm is repeatedly vibrated in this way, and sounds are produced. The soundboard is rigidly connected with the diaphragm, so that the sound generated by vibration is more pleasant. Regardless of the type of horn, the sound is single and harsh.

The automobile horn is used for early warning of special road sections and warning under certain emergency conditions so as to ensure traffic safety. Whereas prior art vehicle horns snap suddenly when they are closer to a pedestrian, producing a high decibel sound that stimulates the eardrum.

Therefore, there is an urgent need for a horn system that can use pre-prepared music, particularly soothing music, as a car alert tone.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has:

1. the utility model discloses a motor vehicle loudspeaker of loudspeaker system through bluetooth setting tone, the driver can be local with the transmission of the prefabricated audio file of oneself to loudspeaker through the bluetooth, and prefabricated audio file can be the music of various tones of various volumes even happy and listened to more make the use utensil individual character of loudspeaker, have more the flexibility that adapts to service environment.

2. The utility model discloses can be with the pronunciation accurate digital audio file that changes into at bluetooth control application terminal, transmit motor vehicle horn device and trigger the broadcast through the bluetooth. The bluetooth control application terminal can send and look for the signal, and this novel motor vehicle horn device can trigger the prefabricated audio file of broadcast after receiving and look for the signal to reach the purpose of looking for the car.

fig. 2 is a schematic structural view of the horn device of the present invention shared by a conventional horn device of a motor vehicle.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It is to be understood that the block diagrams and specific examples are set forth herein for purposes of explanation only and are not intended as limitations on the present invention.

Example 1

As shown in fig. 1, the utility model provides a novel motor vehicle horn device, including power module, audio file storage play module and sound production unit, power module is the power supply of audio file storage play module, and when audio file storage play module was triggered, audio signal transmission to the sound production unit broadcast with the audio file of storage. The stored audio module can be stored locally or an audio file received by the communication device and the audio file storage and playing module through communication. The audio file storage and play module is triggered by the horn trigger switch.

The audio file storage and playing module supports MP3.WAV format hard decoding, various decoding and playing chips can be adopted, the Bluetooth receiving and setting module stores the received digital audio file into a storage space, when a playing control signal sends out a signal, the stored digital audio file can be converted into an analog audio signal by the decoding chip after being converted by an audio DAC, and the analog audio signal is pushed to an audio power amplifier module for playing.
