The purpose of this utility model is to provide a kind of screen acoustical generator simple in structure.
The technical solution of the utility model is as follows: a kind of screen acoustical generator, it comprises screen, thereby described screen acoustical generator also is provided with the moving-iron type driver that the driving screen vibration that is positioned at the screen below makes the screen sounding, the direction of vibration normal to screen of described moving-iron type driver.
Preferably, described screen acoustical generator also comprises the shell that forms the accommodating moving-iron type driver of cavity with screen, and described shell comprises the lower house of placing the moving-iron type driver and around the upper shell of screen periphery.
Preferably, described screen acoustical generator also is provided with the strutting piece of support screen, described strutting piece comprise with the interior ring of screen lower surface butt, be folded in the outer shroud between upper shell and the lower house and be connected in the recessed ring section to lower house of ring and outer shroud.
Preferably, described strutting piece is made by rubber or foam, and the cavity that strutting piece consists of screen and shell seals.
Preferably, described moving-iron type driver comprise magnet frame, cooperate the shell fragment that forms receiving space with magnet frame, be fixed on the shell fragment and with the vibrating mass of screen butt, be positioned at magnet frame magnetic core, be positioned at magnet frame and form the magnet of magnetic gap and be positioned at magnetic gap and the coil of wounded core with magnetic core.
Preferably, described magnet frame comprises bottom surface and the sidewall that is connected with the bottom surface, described shell fragment comprises vibration plane, the fixed part of placing vibrating mass and the connecting portion that connects described vibration plane and fixed part, and described connecting portion coats the sidewall of described magnet frame, and described fixed part is fixed on the bottom surface of described magnet frame.
Preferably, described moving-iron type driver has four, and the arrangement that is centrosymmetric.
The beneficial effects of the utility model are: because the screen of screen acoustical generator below is provided with the moving-iron type driver, the vibration of moving-iron type driver can be so that screen vibrates and sounds.
