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 comprises a mounting shell, a vibration system accommodated in the mounting shell and a magnetic circuit system which drives the vibration systemto vibrate and produce sound and is provided with a magnetic gap, and an upper shell of the mounting shell covers the magnetic circuit system. The loudspeaker is characterized in that a first connecting part is arranged on the face, facing the magnetic circuit system, of the upper shell, a second connecting part is arranged on the face, facing the upper shell, of the magnetic circuit system, and the upper shell and the magnetic circuit system are fixedly connected in a matched mode through the first connecting part and the second connecting part. The loudspeaker is connected and matched with the second connecting part through the first connecting part, so that the upper shell is fixedly matched with the magnetic circuit system, and when the loudspeaker makes a sound, the shell vibration ofthe upper shell is effectively reduced. Meanwhile, when the loudspeaker is influenced by external force, the reliability and stability of internal parts of the mounting shell can be effectively ensured.

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...
