Abstract

The invention discloses a single sound production device, a sound production device module and an electronic terminal. The single sound production device comprises a vibration system and a magnetic circuit system. The vibration system comprises a vibrating diaphragm and a voice coil fixedly connected with the vibrating diaphragm. The magnetic circuit system comprises a magnetic conductive yoke, and a central magnetic circuit and a side magnetic circuit which are arranged on the magnetic conductive yoke. A magnetic gap is formed between the central magnetic circuit and the side magnetic circuit, and the voice coil is suspended in the magnetic gap. The magnetic conductive yoke comprises a horizontal surface located on the bottom surface, the thickness of the magnetic conductive yoke is gradually increased from a first side to a second side to form an inclined surface located on the top surface, and the central magnetic circuit and the side magnetic circuits are arranged on the inclined surface. The invention aims to provide the single sound production device with improved acoustic performance, acoustic yield and tone quality.

Description

technical field [0001] The invention relates to the technical field of sounding equipment, in particular to a single sounding device, a sounding device module and an electronic terminal using the single sounding device. Background technique [0002] With the widespread application of high-quality smart phones, Pads and other portable electronic products, people have higher requirements for high-fidelity sound quality performance of electronic products that can reproduce various sound effects realistically. Existing electronic equipment is affected by its own thickness and structure, which leads to the installation of speaker units into sound-generating modules such as electronic products, resulting in limitations such as poor sound quality and acoustic performance. [0003] The above is only used to assist the understanding of the technical solution of the present application, and does not mean that it is recognized as the prior art. Contents of the invention [0004] The...
