Problems solved by technology

However, in the existing loudspeakers, the magnetic group surrounded by the voice coil is generally composed of a single piece of magnetic steel. The magnetic flux generated by this magnetic group on its periphery is small, and it can only drive one diaphragm to vibrate and sound, and the small magnetic flux causes the drive Insufficient force, which affects the vibration sensitivity of the diaphragm

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a main magnet part, a vibrating system driven by the main magnet part, and a casing used for accommodating the main magnet part and the vibrating system, wherein the main magnet part comprises a first magnetic steel, a first pole core and a second magnetic steel which are sequentially arranged in a superposed manner, and the like poles of the first magnetic steel and the second magnetic steel are opposite to each other; the vibrating system comprises a first vibrating diaphragm fixed to the casing, a first voice coil connected with the first vibrating diaphragm, a second vibrating diaphragm fixed to the casing, and a second voice coil connected with the second vibrating diaphragm; the first vibrating diaphragm and the second vibrating diaphragm are opposite to each other and are arranged in a spaced manner; the main magnet part is arranged between the first vibrating diaphragm and the second vibrating diaphragm and is fixed to the casing; the first voice coil surrounds the main magnet part in a spaced manner, so as to drive the first vibrating diaphragm to vibrate and produce sounds; and the second voice coil surrounds the main magnet part in a spaced manner, so as to drive the second vibrating diaphragm to vibrate and produce sounds.

Description

【Technical field】 [0001] The invention relates to the technical field of electro-acoustic transduction, in particular to a loudspeaker. 【Background technique】 [0002] With the rapid development of science and technology, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to video and audio playback, but also require more requirements for the reliability of audio equipment. Especially with the advent of the 3G era, mobile multimedia technology has also developed. Many audio devices have a variety of entertainment functions, such as video playback, digital cameras, games, GPS navigation, etc., which require more and more sophisticated electronic components in audio devices. and compact. [0003] In audio equipment, a speaker is a commonly used electronic component, mainly used for playing audio signals. However, in the existing loudspeakers, the magnetic group surrounded by the voice coil is generally co...
