Problems solved by technology

The conventional subwoofer generally adopts the traditional speaker structure. Although the cost is low and the process is simple, the problem of vibration imbalance often occurs when it is working, resulting in large low-frequency distortion and poor low-frequency sound quality.

Embodiment Construction

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to a push-pull loudspeaker. The loudspeaker comprises a magnetic circuit structure, a connecting base, a first voice coil, a first frame, a second voice coil and a second frame. According to the push-pull loudspeaker, the first voice coil and the second voice coil are arranged in magnetic gaps of the magnetic circuit structure, and the first voice coil and the second voice coil are fixedly connected. Under the action of a magnetic field, the first voice coil and the second voice coil move together to drive a first vibrating diaphragm and a second vibrating diaphragm which are installed in an opposite mode to move together, so that the effect that one of the two vibrating diaphragms is pushed and the other is pulled is achieved, vibrating is more balanced, and low-frequency distortion is reduced; meanwhile, the first vibrating diaphragm, the connecting base and the second vibrating diaphragm form a resonant cavity body, medium-high frequency response components are filtered out, and the low-frequency tone quality is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of loudspeakers, in particular to a push-pull loudspeaker. Background technique [0002] The speaker is a commonly used electro-acoustic transducer, which has been widely used in televisions, computers, automobiles, mobile phones and other equipment. The speaker drives the voice coil tube to move through the magnetic field, thereby driving the diaphragm to emit sound. Conventional subwoofer speakers generally adopt traditional speaker structure. Although the cost is low and the process is simple, the problem of unbalanced vibration often occurs during its operation, resulting in large low-frequency distortion and poor low-frequency sound quality. Summary of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a push-pull speaker, which reduces low-frequency distortion and improves low-frequency sound quality. [0004] A push-pull speaker includes a...
