Problems solved by technology

[0004] However, existing actuators drive the screen indirectly through the housing
This exciter has a complex structure, a large number of parts, and high production costs.
[0005] In addition, the indirect drive has hysteresis and poor sound production
[0006] In addition, the exciter includes a casing, which makes the volume of the exciter large, which is not conducive to the thinning and miniaturization design of the sound generating device

Abstract

The invention discloses a direct drive type exciter and a screen sounding device. The exciter comprises a magnetic circuit system and a vibration system. The magnetic circuit system connected with thedevice is used for forming a magnetic gap. The vibration system consists of a coil, an elastic support member and a connecting member; the elastic support member includes an outer connecting portion,an inner connecting portion and an elastic portion arranged between the outer connecting portion and the inner connecting portion; a coil and a connecting element are fixed on the two surface of theinner connecting portion respectively; one end, far away from the inner connecting portion, of the coil is inserted into the magnetic gap; one end, far away from the inner connecting portion, of the connecting element is configured to connect a screen; and the outer connecting portion is fixed at a side magnetic circuit part.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic conversion, and more specifically, to a direct-drive exciter and a screen sound generating device. Background technique [0002] In the existing screen sound generating device, an exciter is usually provided. The exciter is fixedly connected with the screen, and is spaced from the housing and other parts of the device. An exciter typically includes a vibrating element and a housing enclosing the vibrating element. The vibrating element may be an electromagnetic vibrating element or a piezoelectric vibrating element. The vibrating element is usually provided with a stator system and a vibrator system. The stator system and the vibrator system are connected. The vibrator system is provided with a mass block. The vibration amplitude of the vibrator system is increased by the mass block. [0003] The housing encapsulates the vibrating element within the cavity. The stator system is fix...
