The speaker box provided by the present disclosure includes a housing with an accommodation space and a speaker in the accommodation space. The speaker includes a diaphragm for radiating sound. The housing includes a ring-shaped step for fixing the speaker. The step further forms a fastening slot for fixing the speaker. The stop further includes a number of recesses extending from a surface toward the fastening slot along a direction away from the fastening slot. BY virtue of the recesses, without changing the vibration space, the acoustic capacitor of the front cavity is increased, and the harmonic peak is lowered. Acoustic performance is accordingly improved.

Speaker box

The present disclosure a speaker box including: a lower cover; an upper cover enclosing an accommodating space together with the lower cover; a sounding unit accommodated in the accommodating space. The sounding unit and the upper cover together enclose a front chamber, and the sounding unit. The lower cover and the upper cover together enclose a rear chamber. The speaker box further includes an air-permeable spacer assembly sleeved on an end of the sounding unit located in the rear chamber. The air-permeable spacer assembly includes a frame made of sound-absorbing cotton sleeved on the sounding unit, and an air-permeable spacer connected to a side of the frame close to the lower cover. The rear chamber is filled with sound-absorbing particles, and the air-permeable spacer assembly isolates the sounding unit from the sound-absorbing particles. Compared with the related art, the speaker box disclosure has a better low-frequency acoustic performance.

The present disclosure discloses a speaker box, including a housing with an accommodation space. The housing includes an upper case and a lower case. A speaker is received in the accommodation space. The speaker includes a diaphragm for producing sound. The speaker box further includes a passageway, a front sound cavity formed between the diaphragm and the upper case, a front cavity, a receiving slot formed in the upper case recessing from a side of the upper case adjacent to the diaphragm along a direction away from the diaphragm; and an air adsorbing layer received in the receiving slot, a steel piece engaging with the upper case and packaging the air adsorbing layer in the receiving slot, and a number of air adsorbing holes for communicating with the front sound cavity.

The present disclosure provides a speaker box, including an upper cover plate and a lower cover plate which cooperate with each other to form accommodating space and a speaker accommodated in the accommodating space, the speaker includes a diaphragm for vibrating and sounding, the diaphragm and the upper cover plate form a front cavity, the speaker box further includes a sounding channel formed by surrounding of the upper cover plate and the lower cover plate, configured to communicate the front cavity with external environment, and a sounding hole communicated with the sounding channel, the speaker is fixed on the upper cover plate, the sounding hole is provided on the lower cover plate, an extending direction of the sounding channel is perpendicular to a vibration direction of the diaphragm. By adopting the speaker of the present disclosure, the assembling yield is high and the sounding effect is good.

A sealing structure includes a housing and a camera module. The housing defines an annular groove. The cameral module is assembled in the housing. The camera module includes a closed, wave-shaped rib, which includes a plurality of waves. The rib is engaged with a wall of the annular groove to create a seal.
