Embodiment 1

[0018] see Figure 1-2 As shown, a kind of sound-tunable speaker dust cover is provided in the present embodiment 1, and the dust cover includes an unwinding roller 1, a winding roller 2, a mesh belt 3, and consists of two horizontal frames 41 and two vertical frames. The frame body 4 that frame 42 constitutes.

[0019] The horizontal frame 41 is provided with two positioning rods 43 arranged perpendicular to the frame body, and the positioning rods 43 adopt flexible rubber rods. The two mullions 42 are telescopic rods with adjustable length, on which bolts 422 are arranged to realize the locking of the telescopic rods.

[0020] The unwinding roller 2 and the winding roller 3 are respectively pivotally connected to two telescopic rods, and are respectively close to a horizontal frame 41. Specifically, the unwinding roller 2 is close to the horizontal frame 41 at the top, and the winding roller 3 is close to the bottom horizontal frame 41. Horizontal frame 41. Knobs 5 are pr...

Embodiment 2

[0025] The structure of this embodiment 2 is substantially the same as that of the embodiment. The difference is that the adjacent meshes are in groups of two, which is suitable for crossover speakers. That is to say, when in use, one piece of mesh cloth corresponds to the tweeter, and another piece of mesh cloth corresponds to the mid-woofer. Since the mesh cloth has a greater influence on high frequencies, the piece of cloth near the unwinding roller in every 0 mesh cloth is open. The porosity is lower than the piece near the winding roll.

Abstract

The invention relates to a tunable speaker dust cover. The tunable speaker dust cover is characterized by comprising an unwinding roller, a wind-up roller, a mesh belt and a frame body composed of two horizontal frames and two vertical frames, wherein the horizontal frames are provided with two locating rods which are arranged vertical to the frame body; the two vertical frames are telescopic rods with adjustable length; the unwinding roller and the wind-up roller are respectively pivoted with the telescopic rods and respectively close to one horizontal frame; the end parts of the unwinding roller and the wind-up roller exposed to the outside of the telescopic rods are both provided with a knob respectively; the mesh belt is composed of two flexible ropes and a plurality of meshes with different aperture ratios, wherein the plurality of meshes are connected between the flexible ropes; the two ends of the flexible ropes are respectively fixed on the unwinding roller and the wind-up roller; the plurality of meshes are mutually spliced; at least one section between the two flexible ropes not smaller than the length area of the telescopic rods is not provided with the meshes.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound-tunable dustproof cover for a sound box. Background technique [0002] The dust cover on the speaker is mainly used to prevent dust and protect the speaker, so as to prevent the speaker's cone from being suffocated or pierced by dust or foreign objects. At the same time, the dust cover is usually dark, and the purpose of this design is also to prevent the direct sunlight on the cone or rubber suspension edge of some speakers, which will make them age. [0003] Although strictly speaking, the use of the dust cover will have a certain degradation effect on the sound of the speaker, and even some HIFI manufacturers directly recommend that the user take off the net cover to use it when listening. However, while the mesh of the dust cover slightly deteriorates the sound of the speaker, it also softens the treble and reduces part of the background noise. Therefore, when t...
