The utility model discloses a following technical scheme realizes above-mentioned mesh, an adjustable loudspeaker of car, including governing system and loudspeaker module, governing system include main control system and with main control system electric connection's noise detection module, detection module and the audio drive module of whistling, noise detection module is used for detecting the car external noise, the detection module of whistling is used for detecting time and frequency of whistling, the input of loudspeaker module passes through audio drive module connects main control system, main control system is through control audio drive module's output is adjusted the sound of loudspeaker module, the detection module of whistling still connects pressure detection module, pressure detection module connects audio drive module, through pressure detection module control the loudspeaker module sound production.

Preferably, the pressure detection modules are provided in plurality and are mounted on a touch area of the steering wheel.

Preferably, the pressure detection module is electrically connected with the whistle detection module through a wake-up module.

Preferably, a set of fixed plate is installed respectively to the both sides of control host computer, and parallel arrangement about every fixed plate of group, and the roof that the control of installation screw rod goes up and down on every fixed plate.

Preferably, the other end of the screw is further provided with an adjusting rotating wheel, wherein the adjusting rotating wheel is arranged at the end part of the screw between the two fixed plates, and the top plate is arranged at the end part of the screw far away from the position between the two fixed plates.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through the noise with time of whistling, the sound of frequency adjustment loudspeaker module, but make the sound of car whistle intelligent adjustment, satisfy the user demand, when the external noise is big, multiplicable loudspeaker sound makes things convenient for more clear of sound propagation, increases and the frequency of whistling along with the time of whistling and uprises, and the sound decibel also follows the increase, is linear transform, warns pedestrian's vehicle more easily.

2. Through the pressure detection module that will install at the steering wheel with the detection module that whistles be connected, pressure detection module awakens up through whistling, after initial whistling, when pressure detection module detected the pressure on the steering wheel, also can open the loudspeaker module and whistling, can put on the button all the time and whistling like this without the navigating mate hand, after initial whistling, still can be through holding the steering wheel and whistling, avoid the one-hand whistling to influence driving safety.

3. Through the roof that can be adjusted by the screw rod to the outside jack-up in main control system both sides installation, only need twist to move the regulation and rotate like this when the main control system installation for the roof moves to the outside, can fix the main control system is unsettled in the installation hole site, is difficult for colliding with the installation hole site, increase of service life.
