Embodiment Construction

[0020] Such as figure 1 , figure 2 and image 3 As shown, the appearance of the active digital ultra-thin surface sound source device is a flat rectangular structure with rounded corners, and its housing is composed of a device base 10 and a fastened and fixed end cover 20 provided on one end thereof. The base body of the device is an integrated bending and welding forming structure of metal profiles, and one end surface thereof forms the sound source end surface of the ultra-thin surface sound source device. The base of the device is provided with a wireless receiver, a controller, a power amplifier, a driver and a sounding diaphragm plate to form the basic drive system of the sound source device, and the plurality of drivers 13 are pasted on the sounding diaphragm plate (not shown in the figure), A bracket 12 is arranged on one end surface of the sound-emitting diaphragm plate, and the driver 13 is fixed on the bracket. A U-shaped bracket 11 is arranged in the base of th...

Abstract

An active digital ultrathin surface sound source device comprises a device base body and a vibration generation diaphragm plate, and is characterized in that a wireless receiver, a controller, a poweramplifier, a driver and a sound production vibration diaphragm plate are arranged in the device base body, and the driver is adhered to the sound production vibration diaphragm plate. The active digital ultrathin surface sound source device is reasonable in structural design, and the cost is effectively saved; the design that the controller and the power amplifier are assembled in the area soundsource device is adopted, the tedious process of externally connecting a power amplifier module is omitted, the installation cost and the material cost of a power transmission cable are saved, meanwhile, due to the integrated module design, the compact assembly structure of the area sound source device is effectively improved, and the sound production effect is improved.

Description

technical field [0001] The invention belongs to ultra-thin surface sound source technology, in particular to an active digital ultra-thin surface sound source device. Background technique [0002] The surface sound source device is a planar sound generating device that can convert electrical signals into sound waves, and is widely used in home theater systems, background music systems, multimedia audio systems, public address systems, etc. In the prior art, the surface sound source device is generally driven by several drivers to drive a vibrating plate to produce sound, and all of them are passive surface sound sources, that is, referring to the principle of ordinary speakers, a separate power amplifier is connected externally to drive the driver to produce sound. Since the signal room of the public broadcasting equipment is generally far away from the loudspeaker device, the cost of the required transmission cable is high, the installation and maintenance are very cumberso...
