Embodiment Construction

[0049] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will facilitate further understanding of the present invention in any form of techniques, but will not limit the invention in any form. It should be noted that several variations and improvements can also be made without departing from the concept of the present invention. These are all of the scope of protection of the present invention.

[0050] The embodiment of the present invention discloses a new type of car vocalization technology, such as figure 1 and figure 2 As shown, including a vehicle vocal system, the system includes a vibrator mechanism, a control module 107, a vehicle bus / upper machine, and a vehicle power module 112. " / " Is expressed as "or". The vibrator is connected to the control module 107. The vibrator mechanism includes a first vibrator 103, a second vibrator 104, a vibrator upper surface 101, and a vibrator lower surface 102. The...

Abstract

The invention provides a vehicle sound production system and method. The vehicle sound production system comprises a vibrator mechanism and a control module connected with the vibrator mechanism. The control module controls the vibrator mechanism to be powered on and powered off. And the vibrator mechanism acts according to the power-on and power-off of the vibrator mechanism to generate sound. According to the invention, water-carrying air can be prevented from entering a sound production area, water vapor condensation is prevented from damaging the vibrator, the problem that the prior art is not waterproof is solved, the problem that an automobile low-speed pedestrian early warning system or a multimedia outgoing system needs to be additionally provided with a loudspeaker is solved, and the cost is reduced; aluminum sheets are used as materials of the oscillator upper surface and the oscillator lower surface, and the upper plane and the lower plane form a shielding cover, so that the anti-EMC capability is remarkably improved.

Description

Technical field [0001] The present invention relates to the technical field of automotive vocal systems, and in particular, to a vehicle phonum system and method. In particular, it is preferred to relate to a new type of car phonum. Background technique [0002] The first vibrator 103 and the second vibrator 104 are constantly absorbed to generate a vibration frequency and sound. It can be used to mount the light fixture, bumper, outer display, etc. of the vehicle, replacing the conventional speaker. However, since the surface sound technology requires a small gap between the vibrators, for the existing light structure, such as the gap between the decorative frame and the outer lens, and the light of the lamp is high, the vibrator and its mounting structure It is not visible to the outside of the headlights. Second, the vibrator of the surface sound technology needs to be used in the waterproof state, and when the internal humidity of the lamp is large, the vibrator will face wat...
