Abstract

The invention relates to a speaker sound cavity box with a sound-guiding pipe groove, wherein the speaker sound cavity box with the sound-guiding pipe groove comprises a sound-guiding pipe sound-closing sheet, the rear sound-cavity sound-guiding pipe groove, an antenna bracket rear sound cavity and a speaker main body, and the sound-guiding pipe sound-closing sheet is used for introducing outer sound into the sound cavity box. The speaker sound cavity box with the sound-guiding pipe groove is characterized in that: the rear sound-cavity sound-guiding pipe groove is closed with the sound-guiding pipe sound-closing sheet by hot-melting and is connected with the antenna bracket rear sound cavity; the sound-guiding pipe groove is arranged on the antenna bracket rear sound cavity, and a circular groove which is matched with the speaker main body is retained on an antenna bracket; and the rear sound-cavity sound-guiding pipe groove is communicated with a rear sound cavity body and is connected to the speaker main body, and the internal wall of the sound-guiding pipe groove is smooth. The bottom of the sound cavity box is further provided with rear sound-cavity sound-closing foam which is used for closing the bottom end and for enabling the sound cavity box to form a semi-closed space. The sound cavity box can be applied to a mobile phone, and the sound cavity box is used for realizing the excellent air inlet/outlet positioning for the sound of the mobile phone and for realizing the adjusting of the sound of a speaker.

Description

Technical field [0001] The invention relates to a horn sound cavity box, and further relates to a mobile phone sound cavity box with a sound duct groove. Background technique [0002] At present, the general mobile phone only installs a speaker inside the casing to emit sound, or installs the speaker in a closed or semi-closed sound cavity to emit sound. This design has a very general effect on music, but the sound is loud and there is no so-called sound quality. [0003] However, in general design, the sound cavity box cannot achieve good air inlet and outlet positioning, and the sound of the horn is also difficult to adjust. When applied on a mobile phone, the sound limitation is always difficult to achieve the best vocal effect. Summary of the invention [0004] In view of the above content, it is necessary to provide a sound-guiding-slot horn sound cavity box that realizes good air inlet and outlet positioning, facilitates adjustment of the sound quality of the horn, and is app...
