Description

Technical Field

[0001] The utility model belongs to the technical field of loudspeakers, and in particular relates to a loudspeaker with a synchronous dustproof mechanism. Background Art

[0002] In the existing Chinese patent database, a patent named "A Speaker Shock Absorption Device" is disclosed, with application number CN202021640942.3 and application date 2020-08-10. A speaker shock absorption device includes a base, the upper part of the base is provided with a groove, and a servo motor is fixedly installed on the inner bottom surface of the groove. Beneficial effect: The utility model adopts a protective cover. When the dustproof net needs to be cleaned, the dustproof net is moved to drive the first circular baffle, the second circular baffle and the first fixed plate to move synchronously. During the movement, the rubber brush plate and the connecting plate are folded in half by the first rotating shaft, the second rotating shaft and the third rotating shaft. When the brush end of the rubber brush plate passes through the dustproof net, the dustproof net is rotated. At this time, the entire dustproof net can be cleaned. During this process, the two sets of telescopic springs are in a compressed state. When cleaning is completed, the dustproof net can be loosened. The two sets of telescopic springs are acted upon by their own elastic force to press the dustproof net to return to its original position. Through the provided dustproof cover, the dustproof net can be cleaned without disassembling the dustproof net, which brings convenience to the cleaning and use of the speaker shock absorber device.

[0003] In the prior art, loudspeakers have a problem where external dust and other particles fall into magnetic gaps, causing friction between the dust and the voice coil, resulting in abnormal sound from the loudspeaker. Therefore, this article aims to propose a loudspeaker with a synchronous dustproof mechanism. When the loudspeaker is working, the dustproof baffle is synchronously opened, and when the loudspeaker is not working, the dustproof baffle is synchronously closed, which has a good dustproof effect and will not affect the normal operation of the loudspeaker. Utility Model Content

[0004] The technical problem to be solved by the present invention is how to solve the problem that external dust and the like fall into the magnetic gap in the existing loudspeaker, causing the dust to rub against the voice coil and thus causing the loudspeaker to produce abnormal sounds. In order to improve its shortcomings, the present invention provides a loudspeaker with a synchronous dustproof mechanism.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] A speaker with a synchronous dustproof mechanism includes a box and a speaker body loaded in the box. The dustproof mechanism includes a mounting base arranged on the side of the box of the speaker body. An electric push rod is arranged on the mounting base. The free end of the electric push rod is connected to a first connecting rod. A rotating shaft is inserted into the free end of the first connecting rod. An inner baffle is sleeved on the rotating shaft. The electric push rod and the speaker body are connected to the same electrical signal.

[0007] As a preferred solution, the free end of the first connecting rod is integrally provided with a second connecting rod, and the first connecting rod and the second connecting rod are cooperated to form an inverted V-shaped connecting rod assembly. A third connecting rod is hinged on the mounting seat above the first connecting rod, and an outer baffle is sleeved on the rotating shaft in the third connecting rod. The free end of the third connecting rod is connected to the free end of the second connecting rod via a long connecting rod inclined downward to form a parallel four-bar linkage mechanism.

[0008] As a preferred solution, a dustproof pad is attached to the inner surface of the inner baffle.

[0009] As a preferred solution, the first connecting rod, the second connecting rod, the third connecting rod and the long connecting rod are all lightweight components.

[0010] As a preferred solution, the mounting base includes a bottom plate fixed to the box body, a U-shaped connecting plate is connected to the bottom plate, and the first connecting rod, the second connecting rod, the third connecting rod and the long connecting rod are distributed on both sides of the connecting plate.

[0011] Compared with the prior art, the beneficial effect of the present invention is that due to the setting of the dustproof mechanism and the connection with the speaker body with the same electrical signal, the two work synchronously. When the speaker is working, the dustproof baffle is opened synchronously, and when the speaker is not working, the dustproof baffle is closed synchronously, which effectively improves the dustproof effect. The device is suitable for industrial production and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the present utility model.

[0013] In the figure: 1 box, 2 speaker body, 3 mounting base, 4 electric push rod, 5 first connecting rod, 6 inner baffle, 7 dustproof pad, 8 second connecting rod, 9 third connecting rod, 10 outer baffle, 11 long connecting rod. DETAILED DESCRIPTION

[0014] The technical solution of the present application is further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1The figure shows a speaker with a synchronized dustproof mechanism. The speaker comprises a housing 1 and a speaker body 2 mounted within the housing 1. The dustproof mechanism includes a mounting base 3 positioned on the side of the speaker body 2 on the housing 1. Mounting base 3 is provided with an electric push rod 4. The free end of the push rod 4 is connected to a first connecting rod 5. A rotating shaft is inserted into the free end of the first connecting rod 5, and an inner baffle 6 is sleeved on the rotating shaft. The push rod 4 and the speaker body 2 are connected to the same electrical signal. The free end of the first connecting rod 5 is integrally provided with a second connecting rod 8. The first and second connecting rods 5 and 8 cooperate to form an inverted V-shaped connecting rod assembly. A third connecting rod 9 is hingedly connected to the mounting base 3 above the first connecting rod 5. An outer baffle 10 is sleeved on the rotating shaft within the third connecting rod 9. The free ends of the third connecting rod 9 and the second connecting rod 8 are connected via a long, downward-angled connecting rod 11, forming a parallelogram linkage. A dustproof pad 7 is attached to the inner surface of the inner baffle 6. The dustproof pad 7 prevents the inner baffle 6 from hard contact with the surface of the speaker body 2, which could damage or cause bumps to the speaker body 2. The first connecting rod 5, second connecting rod 8, third connecting rod 9, and long connecting rod 11 are all lightweight components. The mounting base 3 includes a bottom plate 301 fixed to the box body 1. A U-shaped connecting plate 302 is connected to the bottom plate 301. The first connecting rod 5, second connecting rod 8, third connecting rod 9, and long connecting rod 11 are distributed on both sides of the connecting plate 302.

[0016] When the speaker body 2 and the electric push rod 4 receive the electrical signal synchronously, the speaker body 2 works normally. At the same time, the free end of the electric push rod 4 extends after receiving the electrical signal, the first connecting rod 5 and the second connecting rod 8 rotate counterclockwise, and the third connecting rod 9 and the long connecting rod 11 rotate synchronously with the rotation of the second connecting rod 8, so that the inner baffle 6 and the outer baffle 10 are opened together to avoid affecting the sound effect of the speaker body 2. On the contrary, when the speaker body 2 cuts off the electrical signal, the piston rod of the electric push rod 4 is retracted, and the inner baffle 6 and the outer baffle 10 are re-covered on the upper surface of the speaker body 2, among which the inner baffle 6 plays the main dust-proof role, and the outer baffle 10 plays an auxiliary role.

[0017] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solutions disclosed in the present invention, technicians in this field can make some substitutions and deformations of some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
