Problems solved by technology

At present, the traditional loudspeaker often needs to install the vibration system and the magnetic circuit system in the installation shell. The upper shell of the installation shell often vibrates (shell vibration) following the magnetic circuit system. At the same time, when the speaker is subjected to external force, the vibration The stability of the system and the magnetic circuit system in the installation shell is also poor

Abstract

The invention provides a loudspeaker. The loudspeaker includes: an installation housing, a vibration system accommodated in the installation housing, and a magnetic circuit system that drives the vibration system to vibrate and sound and has a magnetic gap. The upper housing cover of the installation housing is arranged on the On the magnetic circuit system, it is characterized in that a first connection portion is provided on a side of the upper case facing the magnetic circuit system, and a second connection portion is provided on a side of the magnetic circuit system facing the upper case, so The above housing is fixedly connected with the magnetic circuit system through the first connection part and the second connection part. The speaker is connected and matched through the first connecting part and the second connecting part, so that the upper case and the magnetic circuit system are fixedly matched, and when the speaker makes sound, the case vibration of the upper case is effectively reduced. At the same time, when the loudspeaker is affected by external force, it can also effectively ensure the reliable stability of the internal components of the installation housing.

Description

【Technical field】 [0001] The invention relates to the technical field of sound generating devices, in particular to a loudspeaker. 【Background technique】 [0002] The loudspeaker includes a vibration system and a magnetic circuit system. First, a magnetic gap is formed in the magnetic circuit system, and the vibration system uses a voice coil to place in the magnetic gap. At this time, after power is applied, the voice coil will vibrate in the magnetic gap of the magnetic circuit system at different frequencies, thereby realizing The vibration of the vibration system produces sound. At present, the traditional loudspeaker often needs to install the vibration system and the magnetic circuit system in the installation shell. The upper shell of the installation shell often vibrates (shell vibration) following the magnetic circuit system. At the same time, when the speaker is subjected to external force, the vibration The stability of the system and the magnetic circuit system...
