Problems solved by technology

Since the sound outlet is connected to the external connection, if the sound outlet is too large, dust and impurities from the outside will easily enter the shell from the sound outlet, which will easily cause damage to the internal parts of the shell; if the sound outlet is too small, the electroacoustic It is difficult for the sound from the components to come out from the sound hole, which makes the volume of the electro-acoustic components low or no sound, which affects the user's experience

Embodiment 1

[0064] like Figure 1-Figure 2 As shown, in this embodiment, the housing 100 of the mobile phone includes: a display screen cover 110 , a front cover 120 , a first dustproof net 130 and a rear cover 140 . Wherein, the display screen cover 110 is provided with a through hole 111 and the display screen cover 110 is embedded on the outer surface of the front cover 120 , and the sound hole 123 is provided on the front cover 120 . like figure 2 As shown, the sound outlet 123 is opposite to and communicated with the through hole 111 , and the sound can be transmitted to the outside of the casing 100 through the sound outlet 123 . The first dust-proof net 130 is interposed between the front cover 120 and the display screen cover 110 to separate the through hole 111 from the sound outlet 123 , thereby preventing impurities such as dust from entering the sound outlet 123 .

[0065] Further, as figure 2 As shown, the first dustproof net 130 may have a bent portion 131 , and the ben...

Embodiment 2

[0070] like Figure 3-Figure 4 As shown, the difference from Embodiment 1 is that in this embodiment, in the direction from the first opening 124a to the second opening 125a, the cross-sectional area of ​​the first hole segment 124 gradually decreases. Thus, dust can be effectively prevented from accumulating at the sound outlet 123 , thereby reducing the possibility of dust and other impurities blocking the sound outlet 123 , and at the same time increasing the sound outlet area and reducing the sound resistance of the casing 100 .

Abstract

The invention discloses a shell of a terminal, and the terminal. A mounting cavity suitable for accommodating an electroacoustic assembly is formed in the shell; a sound outlet communicating with the mounting cavity is formed in the shell; one end, near the mounting cavity, of the sound outlet is provided with a first opening; one end, far away from the mounting cavity, of the sound outlet is provided with a second opening; and the cross section area of the first opening is larger than that of the second opening. According to the shell of the terminal provided by the invention, the cross section area of the first opening, near the mounting cavity, of the sound outlet is set to be larger than that of the second opening, far away from the mounting cavity, of the air outlet, so sound can be outputted from the sound outlet successfully, external dust can be prevented from entering the shell from the sound outlet or dust can be prevented from being accumulated at the sound outlet, the dustproof property of the shell is improved, the resistance of the shell on sound is reduced and the sound volume of the terminal is increased.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a terminal casing and a terminal. Background technique [0002] In the related art, a mobile terminal (such as a mobile phone) is provided with an electro-acoustic component, and the sound emitted by the electro-acoustic component is transmitted through a through hole in the shell of the terminal. Since the sound outlet is connected to the external connection, if the sound outlet is too large, dust and impurities from the outside will easily enter the shell from the sound outlet, which will easily cause damage to the internal parts of the shell; if the sound outlet is too small, the electroacoustic It is difficult for the sound from the components to come out from the sound hole, so that the volume of the electro-acoustic components is low or there is no sound, which affects the user's experience. Contents of the invention [0003] The present invention aim...
