Loudspeakers, loudspeaker assemblies and portable electronic devices

Abstract

The present invention provides a loudspeaker, which is characterized in that it includes a first diaphragm group, a second diaphragm group, and a first voice coil and a second voice coil located between the first diaphragm group and the second diaphragm group. And the magnetic circuit system, the first diaphragm group, the second diaphragm group, the first voice coil and the second voice coil are arranged on the same center line, and the first voice coil is installed on the first diaphragm group , the second voice coil is mounted on the second diaphragm group, the magnetic field generated by the magnetic circuit system intersects the center line, the first voice coil is spaced opposite to the second voice coil, and the first voice coil A voice coil and a second voice coil are at least partly located in the magnetic field generated by the magnetic circuit system and have opposite vibration directions, the first voice coil and the second voice coil are respectively the first diaphragm group and the second diaphragm The groups provide vibration force to make the first diaphragm group and the second diaphragm group emit sound in two opposite directions.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker and a loudspeaker assembly. Background technique [0002] With the development of portable electronic device technology, people have higher and higher requirements for external sound effects of portable electronic devices, such as notebook computers. In order to improve the low-frequency frequency response of the notebook computer, the amplitude design of the micro-speaker of the notebook computer is getting larger and larger. In large-amplitude applications, the vibration of the voice coil and diaphragm of the micro-speaker will stimulate the keyboard to vibrate, which will affect the user's experience of using the keyboard, and will generate noise that will affect the sound quality of the speaker. At present, the vibration of the keyboard is reduced by reducing the amplitude of the voice coil of the speaker, but at the same time, the loudness of the low freq...

AI Technical Summary

Problems solved by technology

In large-amplitude applications, the vibration of the voice coil and diaphragm of the micro-speaker will excite the keyboard to vibrate, which will affect the user's experience of using the keyboard, and will produce noise that will affect the sound quality of the loudspeaker

At present, the vibration of the keyboard is reduced by reducing the amplitude of the voice coil of the speaker, but at the same time, the loudness of the low frequency is reduced, and the sound effect is sacrificed.
