Abstract

The invention discloses a novel portable loudspeaker box. The novel portable loudspeaker box comprises a box body and a loudspeaker; the box body is of a hollow structure of which one end is open; a first elastic box cover is arranged on the box body; a sounder of the loudspeaker is located in the cavity of the box body; the first elastic box cover is connected with the top end of the loudspeaker; a folding ring for radiating sound to the outside is formed on the first elastic box cover. The novel portable loudspeaker box is excellent in low frequency performance; airflow noise can be avoided.

Description

technical field [0001] The invention relates to a sound box, in particular to a novel portable sound box. Background technique [0002] With the advancement of science and technology and the continuous improvement of market demand, portable speaker products are becoming more and more popular. While portable sound box products are widely popular, their products are also becoming more and more miniaturized, especially the volume of the box body is becoming smaller and smaller. With such a small volume, in order to obtain better product sound quality, it is necessary to improve the acoustic performance of the speaker performance and the cabinet structure. Due to structural limitations, the common speaker design tends to design the speaker as a closed box without other radiators or an open box with an inverter tube. However, the aforementioned closed box is difficult to obtain better low-frequency performance, while the open box will bring obvious airflow noise when it brings ...
