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 installation housing is provided with a sound outlet, and its characteristics That is, the magnetic circuit system includes a magnetic bowl and a magnetic induction assembly, the magnetic bowl is covered on the magnetic induction assembly, and a first recess is provided on the side of the magnetic bowl away from the magnetic induction assembly , the mounting shell is provided with a second recess on the surface corresponding to the magnetic bowl, the first recess cooperates with the second recess to form a sound outlet channel, and the sound outlet channel and the outlet The sound ports are connected. The loudspeaker shortens the channel distance of the vibration sound wave from the inside of the installation shell, and ensures the high-frequency performance when the vibration sound wave is transmitted out of the sound port.

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...
