Abstract

The invention provides a loudspeaker box capable of increasing an effective vibration area. The loudspeaker box comprises a box body with an accommodating cavity and a sound production device, the accommodating cavity is divided into a front cavity and a rear cavity by a partition plate; a single leakage hole communicated with the rear cavity is formed in the partition plate; a sound outlet hole communicated with the front cavity is formed in the box body in a penetrating manner; the sounding device is suspended in the front cavity; the sounding device comprises a basin stand, a vibration system and a magnetic circuit system. A leakage hole communicated with the single leakage hole is formed in the basin frame; the vibration system comprises a basin stand, an upper vibrating diaphragm, a lower vibrating diaphragm, an upper voice coil, a lower voice coil and a skeleton connecting the lower voice coil and the lower diaphragm, wherein the upper vibrating diagraphram the lower vibrating diaphragm are opposite in vibration directions; the magnetic circuit system comprises a clamping plate, a first magnetic part, a second magnetic part forming an inner magnetic gap with the first magnetic part, and a third magnetic part forming an outer magnetic gap with the second magnetic part. The third magnetic part is provided with a leakage channel communicated with the outer magnetic gap and the leakage hole, the upper voice coil is inserted into the inner magnetic gap, the lower voice coil is inserted into the outer magnetic gap, and the clamping plate is provided with an avoidance hole for avoiding the framework.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a speaker box applied to portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, speaker boxes for playing sound are widely used in current smart mobile devices. [0003] The loudspeaker box includes a box body with an accommodating cavity and a sound-generating device arranged in the box body, and a sound hole is run through the box body. The sound emitting device in the related art has only one sound emitting surface, which is not conducive to the improvement of the sensitivity of the speaker box. [0004] Therefore, it is nec...
