Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions are used in this specification for the purpose of description only.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used in the description of the present inv...

Abstract

The invention relates to an audio unit and an audio driving mechanism thereof, and relates to the technical field of loudspeakers. The audio driving mechanism comprises an armature, a magnet, a fixing part, a coil, and a driving rod, wherein a rotating part is arranged on the armature; the magnet is arranged close to the side of at least one end surface of the armature; the fixing part is in rotational matching with the rotating part, and arranged on the magnet or arranged on a shell for containing the audio driving mechanism or arranged on a bracket; the coil is used for sleeving the armature; one end of the driving rod is fixedly connected with the armature; the audio unit comprises a vibrating diaphragm, the shell and the audio driving mechanism; the other end of the driving rod is connected with the vibration diaphragm, and the audio driving mechanism and the vibrating diaphragm are arranged in the shell. The audio unit induces and generates the magnetism when an AC signal passes through the coil, the magnetized armature and the magnet are in attraction or repelling, two ends of the armature are driven to synchronously realize up-down tilting through the rotational matching of the rotating part arranged on the armature and the fixing part, and then the driving rod drives the vibrating diaphragm to vibrate, the produced resonant frequency is low, and the low frequency effect is good.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to an audio unit and its audio driving mechanism. Background technique [0002] At present, the audio unit used in moving iron earphones or speakers on the market usually includes a U-shaped armature, magnets on both sides of the free end of the U-shaped armature, and coils wound on the U-shaped armature. When the electrical signal passes through the coil, the coil induces magnetization, thereby magnetizing the U-shaped armature placed in the coil, and the free end of the magnetized U-shaped armature will attract or repel each other with the magnets on the upper and lower sides , vibration occurs, and then the driving rod arranged at the free end of the U-shaped armature drives the diaphragm to vibrate, and the diaphragm agitates the air in the earphone or speaker cavity to produce sound. [0003] However, because the audio unit in the traditional moving iron earphone or speak...
