Sound processing system

Abstract

The invention relates to the technical field of sound processing, in particular to a sound processing system which is applied to a large-screen mobile terminal. The sound processing system comprises a display device, a border device and a microphone device, wherein at least one sound transmission hole is formed in a contact surface with the display device on the border device; the microphone device is arranged close to the display device, and is kept a predetermined distance away from the border device; the predetermined distance is used for accommodating a rectangular sound transmission tube; and the sound transmission tube is used for connecting a sounding hole of the microphone device and the sound transmission hole. Compared with the prior art, the sound processing system has the advantages that the sound transmission hole does not need to be formed on glass, so that the production process requirement on the glass is lowered greatly, and the glass yield is increased. One rectangular sound transmission hole is adopted, and the sounding hole of the microphone device is connected with the sound transmission hole, so that a sound transmission effect can be achieved by bending the sound transmission tube once without secondary bending; the thickness of the mobile terminal is reduced further; meanwhile, a narrow border design is realized.

Description

technical field [0001] The invention relates to the technical field of sound processing, in particular to a sound processing system applied to a large-screen mobile terminal. Background technique [0002] Most of the display devices of existing large-screen mobile terminals are made of glass material. In order to achieve ultra-thin and narrow frame of the mobile terminal, the camera device of the mobile terminal is installed on the upper end of the display device 1', and the microphone 2' is also It needs to be installed on the upper end of the display device 1', but the installation of the microphone 2' needs to drill a hole on the display device 1'. The hole will cause the yield of the display device 1' (glass material) to drop by 10% in the production process, and its production cost is relatively high. In order to improve the yield of the display device 1' (glass material), such as figure 1 As shown in the sectional view of a mobile terminal, a collection hole 5' for co...

[0002] Most of the display devices of existing large-screen mobile terminals are made of glass material. In order to achieve ultra-thin and narrow frame of the mobile terminal, the camera device of the mobile terminal is installed on the upper end of the display device 1', and the microphone 2' is also It needs to be installed on the upper end of the display device 1', but the installation of the microphone 2' needs to drill a hole on the display device 1'. The hole will cause the yield of the display device 1' (glass material) to drop by 10% in the production process, and its production cost is relatively high. In order to improve the yield of the display device 1' (glass material), such as figure 1 As shown in the sectional view of a mobile terminal, a collection hole 5' for collecting voice information is usually opened at the junction of the display device 1' (glass material) and the frame 3', and then the collection hole 5' is used to collect voice information through the sound guide tube 4'. The voice information of the sound guide is guided to the microphone 2', and the sound guide tube 4' is usually a two-fold pipe. During the installation of the mobile terminal, the bent section of the sound guide tube 4' is parallel to the display device 1', and the sound guide tube 4' 'Usually there is a certain thickness, so the bending section of the sound guide tube 4' will increase the thickness of the mobile terminal, which is not conducive to the ultra-thin design of the mobile terminal. material) perpendicular to the display device 1' (glass material), there is also a certain width between the two sections perpendicular to the display device 1' (glass material), which is also not conducive to the narrow frame 3' design of the display device 1' (glass material)

In order to avoid that the thickness or width of the sound guide tube 4' is not conducive to the realization of ultra-thin and narrow frame design, there is also a direct use of the display device 1' (glass material) as a part of the sound guide tube 4', but the display device 1' (glass material) Material) and the sound guide tube 4' are heterogeneous materials, the sealing performance is relatively poor, and the sound guide effect is low
