Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker diaphragm structure. Background Art

[0002] The loudspeaker diaphragm, also known as a "speaker", is a very commonly used electroacoustic transducer device, which can be seen in all electronic and electrical devices that produce sound. The loudspeaker diaphragm is a transducer device that converts electrical signals into sound signals. The performance of the loudspeaker diaphragm has a great impact on the sound quality. The loudspeaker diaphragm is the weakest device in audio equipment, and for the sound effect, it is also the most important component. There are many types of loudspeaker diaphragms, and the prices vary greatly. Audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects and resonate with the surrounding air to produce sound. The loudspeaker diaphragm is a component in the loudspeaker diaphragm.

[0003] For example, an improved loudspeaker diaphragm with the authorization announcement number CN209218372U. By using the cooperation of an installation seat, a housing, a sealing gasket, a surround, a diaphragm body, a base layer, a damping layer, a first elastic body layer, a foaming layer and a second elastic body layer, the above document solves the problems that the existing improved loudspeaker diaphragm is prone to membrane folding and membrane rupture. The improved loudspeaker diaphragm has the advantages of not being prone to membrane folding and rupture and is worthy of promotion. However, during the use of the loudspeaker diaphragm structure in the above document, due to long-term use, the sealing gasket between the housing of the installation shell and the loudspeaker diaphragm structure is prone to aging after long-term use, resulting in gaps between the housing of the installation shell and the loudspeaker diaphragm structure, allowing dust to enter the interior of the audio, thus causing damage to the audio and affecting its service life;

[0004] At the same time, during the use of the loudspeaker diaphragm structure in the above document, due to the influence of the external environment of the diaphragm, the diaphragm is in contact with moisture and humidity factors for a long time, making the internal structure of the diaphragm prone to erosion and resulting in the aging of the diaphragm. The loudspeaker diaphragm structure in the above document lacks a protection structure, thus leading to the diaphragm being prone to breakage and damage, affecting the use of the loudspeaker diaphragm structure. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the problems that the aging of the sealing gasket easily causes gaps between the housing of the installation shell and the loudspeaker diaphragm structure, allowing dust to enter the interior of the audio and causing damage to the audio, and that the diaphragm is in contact with moisture and humidity factors for a long time, resulting in the aging of the diaphragm, and to propose a loudspeaker diaphragm structure.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] Design a speaker diaphragm structure, including a mounting base and a housing. The left end of the mounting base is fixedly connected to the housing. The outer wall of the housing is fixedly connected to a fixing plate. A sealing gasket is arranged on the right side of the housing. A surround body is arranged on the right side of the sealing gasket. A protection structure is arranged inside the surround body. Both sides of the fixing plate are fixedly connected to a mounting shell through a plurality of fixing bolts. The right end of the sealing gasket abuts tightly against the mounting shell. Sealing structures are arranged on both sides of the fixing plate.

[0008] Preferably, the sealing structure includes a spring. One end of the spring is fixedly connected. The other end of the spring is fixedly connected to a sliding rod. The right ends of a plurality of the sliding rods are fixedly connected to an annular pressing plate. The right end of the annular pressing plate is fixedly connected to a rubber sleeve.

[0009] Preferably, the outer wall of the rubber sleeve abuts tightly against the mounting shell.

[0010] Preferably, the outer walls of a plurality of the sliding rods are all slidably connected to the fixing plate.

[0011] Preferably, the protection structure includes a protection component. The outer end of the protection component is adhered to the surround body. The bottom end of the protection component is adhered to a strengthening component.

[0012] Preferably, the bottom end of the strengthening component is adhered to the diaphragm main body.

[0013] For the speaker diaphragm structure proposed by the present utility model, the beneficial effects are as follows: When the rubber sleeve moves leftward, the rubber sleeve drives the annular pressing plate to move leftward. The annular pressing plate drives the sliding rod to move leftward along the fixing plate. The sliding rod drives the spring to compress. When the sealing gasket ages, the rubber sleeve seals the housing of the speaker diaphragm structure. When there is a gap due to the aging of the rubber sleeve and the mounting shell, the elastic force of the spring acts on the annular pressing plate through the sliding rod. Thus, the annular pressing plate presses the rubber sleeve to make up for the gap, avoiding the situation that when the sealing gasket ages, there is an easy gap between the mounting shell housing and the speaker diaphragm structure, resulting in dust entering the interior of the audio and causing damage to the audio, and improving the service life;

[0014] The material of the protection component is PEVE fluorocarbon resin material, which has excellent weather resistance. The material of the strengthening component is ethylene acrylate rubber, with excellent weather resistance and wear resistance. Thus, the weather resistance of the diaphragm main body is increased, preventing the situation that the diaphragm ages due to long-term contact with moisture and humidity factors.

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the accompanying drawings:

[0022] Embodiment 1:

[0023] Referring to the attached Figures 1-5 : In this embodiment, a loudspeaker diaphragm structure includes a mounting base 1 and a housing 2. The left end of the mounting base 1 is fixedly connected to the housing 2. The outer wall of the housing 2 is fixedly connected to a fixing plate 5. A sealing gasket 6 is arranged on the right side of the housing 2. A folding ring body 7 is arranged on the right side of the sealing gasket 6. A protection structure 3 is arranged inside the folding ring body 7. Both sides of the fixing plate 5 are fixedly connected to a mounting shell 10 through a plurality of fixing bolts 9. The right end of the sealing gasket 6 abuts against the mounting shell 10. Sealing structures 4 are arranged on both sides of the fixing plate 5.

[0024] The sealing structure 4 includes a spring 4a1. One end of the spring 4a1 is fixedly connected. When the housing 2 is installed on the mounting housing 10 through the fixing bolts 9, the rubber sleeve 4a4 is affected by the reaction force of the mounting housing 10, causing the rubber sleeve 4a4 to move leftward. The rubber sleeve 4a4 drives the annular pressing plate 4a3 to move leftward. The annular pressing plate 4a3 drives the slide rod 4a2 to move leftward along the fixing plate 5. The slide rod 4a2 drives the spring 4a1 to compress. When the gasket 6 ages, the housing 2 of the speaker diaphragm structure is sealed by the rubber sleeve 4a4. When a gap appears due to the aging of the rubber sleeve 4a4 and the mounting housing 10, the elastic force of the spring 4a1 acts on the annular pressing plate 4a3 through the slide rod 4a2, so that the annular pressing plate 4a3 presses the rubber sleeve 4a4 to fill the gap. The other end of the spring 4a1 is fixedly connected to the slide rod 4a2. The right ends of multiple slide rods 4a2 are fixedly connected to the annular pressing plate 4a3. The right end of the annular pressing plate 4a3 is fixedly connected to the rubber sleeve 4a4. The outer wall of the rubber sleeve 4a4 abuts tightly against the mounting housing 10. The outer walls of multiple slide rods 4a2 are all slidably connected to the fixing plate 5.

[0025] The protection structure 3 includes a protection component 301. The outer end of the protection component 301 is adhered to the surround 7. The material of the protection component 301 is PEVE fluorocarbon resin material, which has excellent weather resistance. The material of the reinforcement component 302 is ethylene acrylate rubber, with excellent weather resistance and wear resistance, thus increasing the weather resistance of the diaphragm body 8. The bottom end of the protection component 301 is adhered to the reinforcement component 302. The bottom end of the reinforcement component 302 is adhered to the diaphragm body 8.

[0026] Working principle:

[0027] When the housing 2 is installed on the mounting housing 10 through the fixing bolts 9, the rubber sleeve 4a4 is affected by the reaction force of the mounting housing 10, causing the rubber sleeve 4a4 to move leftward. The rubber sleeve 4a4 drives the annular pressing plate 4a3 to move leftward. The annular pressing plate 4a3 drives the slide rod 4a2 to move leftward along the fixing plate 5. The slide rod 4a2 drives the spring 4a1 to compress. When the gasket 6 ages, the housing 2 of the speaker diaphragm structure is sealed by the rubber sleeve 4a4. When a gap appears due to the aging of the rubber sleeve 4a4 and the mounting housing 10, the elastic force of the spring 4a1 acts on the annular pressing plate 4a3 through the slide rod 4a2, so that the annular pressing plate 4a3 presses the rubber sleeve 4a4 to fill the gap, avoiding the situation that when the gasket ages, gaps are likely to appear between the housing of the mounting housing and the speaker diaphragm structure, resulting in dust entering the interior of the speaker and causing damage to the speaker, and improving the service life;

[0028] The material of the protection component 301 is PEVE fluorocarbon resin material, which has excellent weather resistance. The material of the reinforcement component 302 is ethylene acrylate rubber, with excellent weather resistance and wear resistance, thereby increasing the weather resistance of the diaphragm body 8 and preventing the diaphragm from aging due to long-term contact with moisture and humidity factors.

[0029] Embodiment 2:

[0030] Refer to the attached Figures 1-5 : In this embodiment, a loudspeaker diaphragm structure, wherein the sealing structure 4 may further include a round block 4b1, and the inner wall of the round block 4b1 is fixedly connected to the slide rod 4a2. The force-bearing area between the spring and the slide rod 4a2 is increased by the round block 4b1, making the force on the slide rod 4a2 more stable.

[0031] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
