Abstract

The invention discloses a handheld digital device structure with expandable sound chambers and speakers in the technical field of electronic devices. The handheld digital device structure comprises a first speaker, a second speaker, a pcb (Printed Circuit Board), a first sound chamber wall, a second sound chamber wall and sound chamber sealing covers, wherein the first sound chamber wall and the pcb form a first sound chamber space, and the first sound chamber wall and the second sound chamber wall form a second sound chamber space; one end of the first sound chamber wall is provided with a first opening, and the first speaker is arranged in the first sound chamber space and is electrically connected with the pcb; the sound outlet of the first speaker is arranged towards the first opening of the first sound chamber wall and is in tight fit and connection with the first opening, and the other end of the first sound chamber wall is provided with a through hole which is selectively sealed by the sound chamber sealing cover; the sound chamber sealing cover props against the first sound chamber wall through an elastic element, and a second opening is formed in the second sound chamber wall; and the second speaker is arranged in the second sound chamber space and is electrically connected with the pcb, and the sound outlet of the second speaker is arranged towards the second opening of the second sound chamber wall and is in tight fit and connection with the second opening.

Description

Technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a handheld digital equipment structure with an expandable sound cavity and a speaker. Background technique [0002] The sound quality and sound effect of a speaker is very much related to the size of the speaker cavity. The size of the back cavity has a huge impact on the low-frequency part of the sound, and the low-frequency part of the sound has a strong influence on the sound quality. The larger the back cavity, the more prominent the bass, and subjectively, the sound will be more pleasing. Therefore, the expanded sound cavity can greatly improve the overall sound effect. In recent years, it is very common to use handheld digital devices such as notebook computers, mobile phones, and walkmans with sound chambers to make calls, listen to music, and perform sound processing. In order to be more convenient to use, these handheld digital devices are made smaller...
