Abstract

The invention provides a loudspeaker module and a projection machine. The loudspeaker module comprises a chassis, a plurality of first buffer parts, a loudspeaker and a plurality of second buffer parts, wherein the chassis comprises a plurality of first support pillars; each first buffer part is arranged on one of the first support pillars; the loudspeaker is connected to the first buffer parts; and the second buffer parts are connected to the periphery of the chassis. In virtue of a double-layer vibration-proof structure consisting of the first buffer parts and the second buffer parts, the vibration generated by the loudspeaker can be effectively absorbed.

Description

technical field [0001] The present invention relates to a loudspeaker module and a projector, in particular to a loudspeaker module capable of providing good shockproof effect and a projector equipped with the loudspeaker module. Background technique [0002] Recently, projectors have been widely used. In addition to being used for conference reports in general offices, projectors are also often used in various seminars or academic courses due to their audio-visual playback capabilities. Generally speaking, in addition to the projection module for displaying images, the projector is also equipped with speakers for outputting sound. The speaker will vibrate when outputting sound, causing the projection module and the speaker to resonate. Therefore, the projected picture of the projector will vibrate due to the vibration of the speaker, thereby affecting the stability of the projected picture. Contents of the invention [0003] One object of the present invention is to pr...
