Abstract

The invention provides a loudspeaker box capable of increasing an effective vibration area. The sound 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 anda magnetic circuit system. The basin frame is provided with a first leakage hole and a second leakage hole which are communicated with the single leakage holes. The vibration system comprises an upper vibrating diaphragm and a lower vibrating diaphragm which are respectively fixed at two opposite sides of the basin stand and have opposite vibration directions, an upper voice coil for driving theupper vibrating diaphragm to vibrate and sound, a lower voice coil for driving the lower vibrating diaphragm to vibrate and sound, and a skeleton for connecting the lower voice coil and the lower vibrating diaphragm. The upper vibrating diaphragm, the lower vibrating diaphragm and the basin stand enclose to form an accommodating space for accommodating the magnetic circuit system, the magnetic circuit system divides the accommodating space into an upper cavity communicated with the first leakage hole and a lower cavity communicated with the second leakage hole, and the upper cavity and the lower cavity are not communicated with each other.

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...
