Three-dimensional sound guiding cavity structure for cellphone

Abstract

The invention relates to a three-dimensional sound guiding cavity structure for a cellphone, which comprises a cellphone shell and a back cover, and is characterized in that an independent sound cavity shield is arranged outside a loudspeaker arranged in the cellphone shell; and continuous corrugated arc bulges are formed at the inner wall of the inner cavity of the independent sound cavity shield and comprise large and small corrugated arc bulges, which are sequentially and alternately distributed. A sound cavity is independently manufactured on the loudspeaker of the cellphone, the size of the sound cavity is computed according to the low-sound frequency needing to be realized, the sound cavity shield is manufactured by mould opening, cellphone software can smoothly process audio curves, and the independent sound cavity uses a machine rear shell as the sound cavity, thus being more airtight in structure without air leaking; and the energy generated by the loudspeaker is more concentrated and more powerful when people hear the sound, and the corrugated sound cavity inner wall is matched, so the sound effect is further improved. The three-dimensional sound guiding cavity structure for the cellphone is reasonable in design and ingenious in concept and can realize an ideal sound effect feeling by a small improvement.

Description

technical field [0001] The invention relates to the technical field of smart phones, in particular to a three-dimensional sound guiding cavity structure for mobile phones, and in particular to the sound cavity structure thereof. Background technique [0002] The speaker adopts a closed sound chamber, which can produce different sound chambers, high, medium and low. Existing mobile phones use the back cover to achieve a closed sound chamber, but due to the internal structure of the mobile phone, the sound effect is not ideal, especially The bass effect cannot make people feel more shocking. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional sound guide cavity structure for mobile phones, which adds an independent sound cavity cover outside the speaker of the mobile phone, so that the speaker is in a completely independent sealed space, and the energy generated by the speaker is relatively concentrated, and the listening...
