Optionally, the cross-sectional area of the first hole segment 1214 is gradually increased or kept unchanged in the direction from the sound outlet opening 1212 to the sound inlet opening 1213, in this embodiment, the cross-sectional area is kept unchanged in the direction from the sound outlet opening 1212 to the sound inlet opening 1213 of the first hole segment 1214, the maximum cross-sectional area of the first hole segment 1214 is the cross-sectional area of the side of the first hole segment 1214 away from the sound outlet opening 1212, the second hole segment 1215 is connected to the cross-section of the first hole segment 1214 with the maximum area, and the cross-sectional area gradually increases in the direction from the sound outlet opening 1212 to the sound inlet opening 1213, the maximum cross-sectional area of the second hole section 1215 is the cross-sectional area of the sound inlet opening 1213, the cross-sectional area is larger than the maximum cross-sectional area of the first hole section 1214, so that the sound-emitting holes 1211 can be dust-proof while the size of the sound-emitting opening 1212 is smaller than or equal to the predetermined size, the sound input area of the sound output holes 1211 increases, and the sound output effect of the sound output holes 1211 is improved.
Further, the protective cover 32 of this embodiment further includes a dust-proof net 320, the dust-proof net 320 is attached to the shielding portion 121 at least one side of the shielding portion 121 close to the sound outlet opening 1212 and the sound inlet opening 1213, so that the external dust is adsorbed by the dust-proof net before entering the sound outlet passage 111, and further the external dust is prevented from entering the sound outlet passage 111, thereby improving the dust-proof effect.
Referring to fig. 6, the protective cover 32 of the present embodiment further includes a bottom wall 130, the bottom wall 130 is connected to the peripheral sidewall 120 to form the accommodating space 101, and the bottom wall 130 is disposed opposite to the shielding portion 121.
The protective sheath of the electronic equipment that this embodiment provided, through set up the shielding part that can range upon range of setting with electronic equipment at the all lateral walls of protective sheath, and shielding part is equipped with a plurality of play sound holes that correspond the setting with electronic equipment's play sound passageway, so that the sound that the play sound passageway spreads out to the external world through a plurality of play sound holes, each play sound hole is for going out the sound passageway, it diminishes to go out the sound area, the difficulty that external dust got into out the sound hole has been increased, thereby increase the degree of difficulty that external dust got into the play sound passageway, the dustproof effect to the play sound passageway has been improved, and then the influence that external dust got into the play sound passageway and reduced the play sound effect has been reduced or even eliminated, and further through set up the dust screen near play sound opening and the at least one side of entering the sound opening at the shielding part, prevent external dust from getting into electronic equipment's play sound passageway.
The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
