Embodiment approach

[0035] refer to Figure 2 to Figure 4 , in one embodiment, the sounding diaphragm 210 includes a connecting ring 211, a vibrating inner film 212 and a vibrating outer film 213, the vibrating inner film 212 is sheathed on the outer periphery of the magnetic bowl 320, and the vibrating outer film The membrane 213 is sleeved on the outer periphery of the vibrating inner membrane 212 and spaced apart from the vibrating outer membrane 213, one side of the connecting ring 211 connects the vibrating inner membrane 212 and the vibrating outer membrane 213, and the voice coil support 240 is in contact with the side of the connecting ring 211 away from the vibrating inner membrane 212 and the vibrating outer membrane 213 . Specifically, the vibrating inner membrane 212 and the vibrating outer membrane 213 are spliced ​​through the connecting ring 211 , for example: the vibrating inner membrane 212 and the vibrating outer membrane 213 can both be glued to the connecting ring 211 . At th...

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. The mounting shell is provided with a sound outlet, and the loudspeaker is characterized in that the magnetic circuit system comprises a magnetic bowl piece and a magnetic induction assembly, the magnetic induction assembly is covered with the magnetic bowl piece, a first concave part is arranged on the side face, away from the magnetic induction assembly, of the magnetic bowl piece, a second concave part is arranged on the face, corresponding to the magnetic bowl piece, of the installation shell, the first concave part and thesecond concave part are matched to form a sound outlet channel, and the sound outlet channel is communicated with the sound outlet. According to the loudspeaker, the channel distance of vibration sound waves transmitted from the interior of the mounting shell is shortened, and the high-frequency performance of the vibration sound waves transmitted out of the sound outlet is 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 diaphragm mechanism and a magnetic circuit mechanism. First, a magnetic gap is formed in the magnetic circuit mechanism, and the diaphragm mechanism 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 mechanism at different frequencies, thereby realizing The vibration sound of the diaphragm mechanism is realized. According to different usage requirements, the sound outlet of the speaker is sometimes set on the side of the speaker or the end of the speaker (referring to the end of the speaker and the diaphragm mechanism). Due to the limitation of its own structure, when the traditional loudspeaker emits side sound, the length of the gas guide pipe is relatively long, which affects th...
