A reinforced loudspeaker diaphragm

Abstract

A reinforced loudspeaker diaphragm includes a diaphragm body with a suspension edge and a positioning groove beside the suspension edge. An upper clamping plate is positioned above the suspension edge, with reinforcing ribs and a mounting block on the upper clamping plate. A lower clamping plate is positioned below the suspension edge, with a support block on the lower clamping plate. The support block has a connecting hole with a fixing buckle inside the connecting hole. The solid reinforcing ribs, protruding annularly from the surface of the upper clamping plate, enhance the strength of the upper clamping plate. Even slight misalignment of the mold will not affect the use of the reinforcing ribs, reducing the occurrence of diaphragm breakage. The upper and lower clamping plates are respectively attached to the upper and lower surfaces of the suspension edge, forming a support structure that completely encloses the suspension edge. The reinforcing ribs of the upper clamping plate enhance its own strength, and the support block of the lower clamping plate is rigidly connected to the mounting block of the upper clamping plate through the fixing buckle, sharing the vibration stress of the suspension edge.

Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and in particular to a reinforced loudspeaker diaphragm. Background Technology

[0002] As the core component of a loudspeaker, the performance of the loudspeaker diaphragm directly determines the loudspeaker's sound quality, frequency response range, and lifespan. During loudspeaker operation, the diaphragm vibrates at high frequencies under the driving force of the voice coil, realizing the conversion of electrical signals into acoustic signals. Therefore, its rigidity, toughness, mass distribution, and damping characteristics are crucial to the accuracy of sound reproduction. The performance of the diaphragm depends on its geometry and materials. Currently, some diaphragm components have a suspension edge on the outside of the diaphragm to facilitate diaphragm sealing. However, in some larger loudspeakers, the diaphragm body is heavy, and prolonged vibration can easily lead to suspension edge damage. To solve the above problems, a reinforced loudspeaker diaphragm is proposed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the existing speaker diaphragm body is too heavy, and the suspension edge is easily damaged after long-term vibration.

[0004] The present invention adopts the following technical solution:

[0005] A reinforced loudspeaker diaphragm includes a diaphragm body, a suspension edge on the diaphragm body, a positioning groove next to the suspension edge, an upper clamping plate above the suspension edge, a reinforcing rib on the upper clamping plate, a mounting block on the upper clamping plate, a lower clamping plate below the suspension edge, a bearing block on the lower clamping plate, a connecting hole on the bearing block, and a fixing buckle inside the connecting hole;

[0006] Furthermore, the suspension edge is located at the edge of the diaphragm body, and there are several through positioning grooves at the connection between the suspension edge and the diaphragm body. The suspension edge is generally annular, and the cross-section of the suspension edge is arc-shaped. The suspension edge is made of soft material.

[0007] Furthermore, the upper clamping plate is located above the suspended edge, and the upper clamping plate is in contact with the upper surface of the suspended edge. Several mounting blocks are provided on the inner edge of the upper clamping plate. The mounting blocks correspond to the positioning grooves. The mounting blocks have openings for the fasteners to pass through. Several reinforcing ribs are evenly distributed on the upper surface of the upper clamping plate. The reinforcing ribs protrude from the annular protrusions on the surface of the upper clamping plate and are solid structures, used to strengthen the upper clamping plate.

[0008] Furthermore, the lower clamping plate is located below the suspended edge, and the lower clamping plate is in contact with the lower surface of the suspended edge. Several bearing blocks are provided on the inner edge of the lower clamping plate. The bearing blocks correspond to the positioning grooves. The connecting holes on the bearing blocks correspond vertically to the openings on the mounting blocks. The fixing buckles pass through the connecting holes and the openings of the mounting blocks to fix the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are made of rigid materials.

[0009] Furthermore, the fixing buckle is made of an elastic material, one end of the fixing buckle has a flexible conical buckle head for passing through the connecting hole and the opening of the mounting block, and the other end has a limit block that abuts against the bottom end of the bearing block;

[0010] Furthermore, the connection between the diaphragm body and the suspension edge has reinforcing lines to reduce the impact on strength caused by the four notches on the suspension edge.

[0011] The beneficial effects of this utility model are:

[0012] The upper clamping plate is reinforced with a solid structure, which is a ring-shaped protrusion on the surface of the upper clamping plate. This is used to strengthen the upper clamping plate. Even if there is a slight misalignment in the mold, it will not affect the use of the reinforcing rib and reduce the occurrence of diaphragm breakage.

[0013] The upper and lower clamps are attached to the upper and lower surfaces of the suspended edge respectively, forming a support structure that wraps the entire suspended edge. The reinforcing ribs of the upper clamp enhance its strength, and the load-bearing block of the lower clamp and the mounting block of the upper clamp are rigidly connected by a fixing buckle to share the vibration stress of the suspended edge.

[0014] The mechanical locking design of the elastic fastener avoids the aging risk of adhesive bonding and ensures long-term stability under high-frequency vibration.

[0015] By setting reinforcement lines, the potential strength reduction caused by gaps in the suspension edge is effectively compensated, the overall strength of the suspension edge is improved, and damage is avoided during frequent vibrations. Attached Figure Description

[0023] Example 1

[0024] This utility model provides a reinforced loudspeaker diaphragm, including a diaphragm body 1, an annular suspension edge 2 on the diaphragm body 1, the suspension edge 2 being made of a soft material with a circular arc cross-section, and multiple through positioning grooves 3 being provided at the connection between the suspension edge 2 and the diaphragm body 1, while reinforcing lines are embedded in this area to further enhance the mechanical strength at the connection between the suspension edge 2 and the diaphragm, so as to compensate for the local strength reduction caused by opening the positioning grooves 3.

[0025] An upper clamping plate 4 is provided above the suspension edge 2. The upper clamping plate 4 is a ring plate made of rigid material and is attached to the upper surface of the suspension edge 2. The inner edge of the upper clamping plate is provided with mounting blocks 6 corresponding to the number and position of the positioning grooves 3. Each mounting block 6 has a through hole. The surface of the upper clamping plate 4 is provided with annular protruding reinforcing ribs 5. These solid protruding structures can significantly improve the rigidity of the clamping plate and suppress vibration deformation.

[0026] A lower clamping plate 7 is provided below the suspension edge 2. The lower clamping plate 7 is made of rigid material and fits against the lower surface of the suspension edge 2. The inner edge of the lower clamping plate 7 is provided with bearing blocks 8, the number and position of which correspond to the positioning groove 3. Each bearing block 8 has a connecting hole 9, which is coaxially aligned with the through hole of the mounting block 6 of the upper clamping plate 4.

[0027] The upper clamping plate 4 and the lower clamping plate 7 are connected by a fixing buckle 10. The fixing buckle 10 is made of elastic material, with one end being a conical buckle head that can be elastically deformed and the other end being a limiting block. During assembly, the upper and lower clamping plates 7 are placed on both sides of the suspension edge 2, so that the mounting block 6 and the bearing block 8 are aligned through the positioning groove 3. Then, the conical buckle head of the fixing buckle 10 is passed from top to bottom through the connecting hole 9 of the bearing block 8 and the opening of the mounting block 6. After the buckle head elastically opens, it is locked, and the limiting block abuts against the bottom of the bearing block 8, so as to achieve a tight fixation between the upper clamping plate 4 and the lower clamping plate 7.

[0028] Working principle:

[0029] During manufacturing, the suspension edge 2 can be integrally formed with the diaphragm body 1 through injection molding or compression molding to ensure connection strength. Simultaneously, several through-hole positioning grooves 3 are formed at the connection point between the suspension edge 2 and the diaphragm body 1 for precise positioning during subsequent clamping plate installation. The upper clamping plate 4 is attached to the upper surface of the suspension edge 2, with the mounting block 6 on the inner edge of the upper clamping plate 4 aligned with the positioning grooves 3. The opening on the mounting block 6 corresponds vertically to the connection hole 9 of the lower clamping plate 7. Protruding reinforcing ribs 5 are evenly distributed along the annular raised portion of the surface of the upper clamping plate 4 to improve local stiffness and suppress splitting vibration. The lower clamping plate 7 is attached to the lower surface of the suspension edge 2, with the inner edge of the lower clamping plate 7... The bearing block 8 of the edge is aligned with the positioning groove 3, and the connecting hole 9 is aligned with the opening of the upper clamping plate 4. The upper and lower clamping plates 7 are fastened by the elastic fixing buckle 10 passing through the connecting hole 9 and the opening. After the buckle head of the fixing buckle 10 passes through the hole, it unfolds elastically, and the limiting block abuts against the bottom of the bearing block 8 to form a mechanical lock, so that the upper clamping plate 4 and the lower clamping plate 7 wrap around the suspended edge 2, which strengthens the suspended edge 2 and ensures the flatness of the suspended edge 2. During installation, the fixing buckle 10 is inserted into the connecting hole 9 through the conical buckle head to make it retract. After passing through the hole, it automatically springs back and locks, without the need for additional screws or glue. When disassembling, pinch the conical buckle head to merge it and take it out from the opening.
