Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that in the subwoofer dual-drive low-frequency vibrator in the embodiment of the present invention, the low frequency is relative, and various response frequency ranges can be obtained by changing the width or material thickness of the shrapnel. In order to simplify the description, the subsequent embodiments adopt figu...

Abstract

The invention discloses a miniature low-frequency vibrator capable of being directly driven by an audio signal, which belongs to the technical field of vibrators and comprises a base, an upper cover,a side cover, a flexible circuit board, a coil, a magnet, a balancing weight, elastic pieces, an inner welding sheet, an outer welding sheet, an insulating adhesive tape and a buffer body. According to the invention, the magnet and the coil adopt a double-drive structure of which the upper surface and the lower surface are symmetrical, so that components of electromagnetic force in the non-vibration direction are mutually counteracted, and vibration noise is eliminated. The elastic piece adopts a V-shaped structure, so that the effective length of a deformation area is increased, and the response frequency can be lower. The two V-shaped elastic pieces are distributed in a central symmetry manner, so that the operation is more stable. The buffer body is used for preventing the elastic pieces from bearing large impact force and being damaged when the circuit voltage is too high, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of vibrators, in particular to a vibrator whose response frequency is lower than 100 Hz, can be directly driven by audio signals, and embodies the dynamic effect of super bass. Background technique [0002] In electro-acoustic equipment, the audio signal is restored to sound through the vibration of the sound film of the speaker. If you want to reflect the super bass (below 125Hz), you must use a large-diameter speaker. For headphones and small audio equipment, due to the limitation of installation space, it is impossible to install subwoofer speakers, and only mid-frequency speakers can be used, which cannot reflect the dynamic and shocking effect of subwoofers. Contents of the invention [0003] The purpose of the present invention is to solve the defects of insufficient subwoofer performance of other small audio equipment such as headphones, and provide a vibrator with small installation volume and high low frequ...
