Abstract

The invention provides a loudspeaker box capable of increasing the effective vibration area, which includes a box body and a sound-generating device. The accommodating cavity is divided into a front cavity and a rear cavity by a partition. The sound hole is connected to the front cavity, and the sound-generating device is suspended in the front cavity. The sound-generating device includes a basin frame with a basin leakage hole, a vibration system and a magnetic circuit system. The upper and lower diaphragms in the accommodation space connected by holes and the upper and lower voice coils respectively inserted into the inner magnetic gap and the outer magnetic gap, the magnetic circuit system includes the inner magnetic part and the inner magnetic gap formed between the inner magnetic part and the inner magnetic part. The middle magnetic part, the outer magnetic part forming the outer magnetic gap with the middle magnetic part, the first pole core fixed on the inner magnetic part, the second pole core fixed on the middle magnetic part and the outer magnetic part and fixed on the The third pole core on the inner magnetic part and the middle magnetic part, the middle magnetic part has an air passage connecting the outer magnetic gap and the inner magnetic gap.

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...
