The present application discloses a sounding device including a base, and a vibration system and a magnetic circuit system fixed on the base. The vibration system includes a first diaphragm held on the base, and a voice coil of driving the first diaphragm to make a sound through vibration. The magnetic circuit system has a yoke and a magnetic body part fixed on the yoke. The yoke includes a main body arranged opposite to and apart from the base, and a turnup part fixed to the base. The magnetic circuit system further includes a breathable isolator attached to the turnup part and covering the through hole. Compared with the related art, the sounding device disclosed by the present application can prevent magnets from being separated from the yoke in a dropping experiment.

Sounding device

A speaker box includes an upper shell and a lower shell that define a receiving space, and a speaker unit received in the receiving space and dividing the receiving space into front and rear cavities. The speaker unit includes a diaphragm spaced apart from the upper shell to form a front acoustic cavity. The upper shell is formed with a sound transmitting channel communicating the front acoustic cavity with the outside. The upper shell includes a top wall, and a support wall extending from the top wall towards the lower shell. The speaker box further includes a partition wall extending from the top wall towards the lower shell, and a cover plate extending from the partition wall towards the support wall. The partition wall, the cover plate and the support wall define at least two resonant cavities spaced apart from each other and in communication with the front cavity.

Speaker box

A speaker box is provided in the present disclosure. The speaker box comprises a shell, a speaker, a sound guiding channel, an auxiliary sound cavity, a baffle and a cover plate. The diaphragm separates the receiving space into a front sound cavity and a rear cavity, the sound guiding channel connects the front sound cavity with the outside and forms a front cavity. The auxiliary sound cavity is provided with a first through hole communicating with the front cavity and a second through hole communicating with the outside, and the baffle is completely covered the first through hole. The baffle is provided with a channel therethrough and the auxiliary sound cavity is communicated with the front cavity through the channel. The cover plate completely covers the second through hole. Compared with the related art, the high frequency acoustic performance of the speaker box of the present disclosure is excellent.

Speaker box includes auxiliary sound cavity used as resonator

The present disclosure provides a speaker box which comprises a shell, a support wall, a sound guiding channel, a surrounding wall and a cover plate. The speaker is fixed to support the support wall. The diaphragm of the speaker partitions the receiving space into a front sound cavity and a rear cavity, the sound guiding channel communicates the front sound cavity with the outside and forms a front cavity together with the front sound cavity, the shell, the surrounding wall, the support wall and the cover plate are jointly enclosed as an auxiliary acoustic cavity. The support wall is provided with at least two through-holes intervals, and the auxiliary acoustic cavity is communicated with the front cavity through the through-hole to form a resonant cavity structure of the front cavity. Compared with the related art, the high frequency acoustic performance of the speaker box of the present disclosure is excellent.

The present disclosure provides a speaker box including a shell, a speaker box, a support wall formed by the inner extension of the shell, and a sound guide channel formed in the receiving space. The speaker is fixed to the support wall. The speaker box includes a surrounding wall formed by the inner extension of the shell and a cover plate arranged on the surrounding wall. The shell, surrounding wall, support wall and cover plate are jointly enclosed as auxiliary sound cavity. The support wall is provided with a through-hole, and the auxiliary sound cavity is communicated with the front cavity through the through-hole to form the resonant cavity structure. The speaker box further includes a leakage to achieve the sound pressure balance inside and outside of the shell.
