Abstract

The invention discloses a sound cavity structure and a mobile terminal. The sound cavity structure comprises a shell and a circuit board, a loudspeaker and a supporting plate which are arranged in the shell. The shell comprises a first shell body and a second shell body which are mutually connected. The first shell body is provided with a sound outlet hole penetrating through the first shell body. The internal side of the first shell body is provided with a front cavity channel communicated with the sound outlet hole. The internal side of the second shell body is provided with a slot body used for accommodating the loudspeaker. The mobile terminal comprises the sound cavity structure and a display screen. The display screen is installed at the external side of the second shell body. The sound cavity structure can be applied to the technical field of communication electronics, the defects in the prior art can be effectively overcome by applying the sound cavity structure, an independent application of the integrated BOX can be replaced by the optimized connection arrangement of the component, the limitation caused by the mould manufacturing period and the manufacturing cost of the integrated BOX can be eliminated, the concrete composition of the sound cavity structure can be optimized, the sealing problem caused by the integrated BOX can be avoided and the overall sealing performance of the structure can be enhanced.

Description

technical field [0001] The invention relates to the technical field of communication electronics, in particular to a sound chamber structure and a mobile terminal. Background technique [0002] At present, on smartphones, the integrated box design scheme that seals the speaker separately in a closed sound cavity is becoming more and more popular; among them, the speaker side sound output method mainly adopts the integrated BOX method. In the application of the box integrated sound cavity mentioned above, the mobile phone shell and the box are mostly connected by screws, and the rear shell is connected with the box sound cavity by screws and is set as an integrated structure; the installation process of each component of the box and the rear shell is manual. It is cumbersome and the workload is heavy. [0003] In addition, the above-mentioned box integrated sound cavity needs to customize a special mold, the cost of the above-mentioned special mold is high and the mold manuf...
