Abstract

The invention provides a loudspeaker box, which includes a housing and a sounding unit with a diaphragm housed in the housing. The housing includes a front cover and a rear cover that covers the front cover. The front cover includes a supporting sounding unit. The body has a support on one side of the diaphragm, a sound guide channel that is fixedly connected to the support by injection molding, and a connecting member that is fixedly connected to the support and the back cover. The supporting wall that bends and extends in the direction close to the sounding unit and supports the sounding unit, and the retaining wall that extends from the supporting wall toward the back cover and surrounds the circumference of the sounding unit, the back cover, the support and the The connecting piece is made of metal material. The sounding unit, the supporting piece and the connecting piece together form a front cavity. The sound guide channel connects the front cavity with the outside world. The sounding unit, the front cover and the back cover together form a closed back cavity. The loudspeaker box of the present invention is provided with a metal connecting piece and a back cover, and a support piece and a sound guide channel are added to maximize the back cavity and improve the acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electro-acoustic conversion, in particular to a speaker box and an assembling process thereof. 【Background technique】 [0002] In recent years, with the rapid development of mobile communication technology, consumers are increasingly using mobile communication devices with voice functions, such as cellular phones, handheld game consoles, and laptop computers. As a voice playback device, the design of the speaker box directly affects the voice performance of the mobile communication equipment products of related technologies. In order to meet the requirements of product thinning and high sound quality, the speaker box is required to develop in the direction that is conducive to achieving thinning and high power. [0003] The speaker box of the related art includes a front cover, a rear cover that is covered on the front cover and jointly encloses a receiving space, and a sound-emitting unit received in the receiv...
