Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and more particularly to a simple buckle loudspeaker. Background Art

[0002] Traditional speaker covers are assembled using glue. However, the viscosity of the glue significantly impacts reliability and creates the risk of detachment. This is especially true for speakers with dual magnetic circuits, where the upper and lower magnetic circuits repel each other. This creates a certain repulsive force when the upper and lower covers are assembled. The larger the magnets, the greater the repulsive force, which can even exceed 10N. Therefore, traditional glue alone is no longer sufficient. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combine Figure 1-Figure 3 In this embodiment, the simple snap-on speaker includes a cover 1 and a lower cover 2. The upper cover 1 is provided with a first thin wall 12, and the lower cover 2 is provided with a second thin wall 22. The upper cover 1 and the lower cover 2 are covered by a snap-on structure. The snap-on structure includes a first snap-on structure 11 provided on the first thin wall 12 and a second snap-on structure 21 provided on the second thin wall 22. The second snap-on structure 21 is provided with a snap-on surface 211 that abuts against the first snap-on structure 11. The first snap-on structure 11 is located below the snap-on surface 211. The space enclosed by the upper cover 1 and the lower cover 2 is provided with an upper magnetic circuit 3, a diaphragm 4, a voice coil 5 and a lower magnetic circuit 6 from top to bottom.

[0027] The upper cover 1 is made of plastic and has a certain degree of deformation. The bottom of the upper cover 1 is a flat structure for accommodating magnets, with a hole in the middle for the speaker's sound outlet. The lower cover 2 is also made of plastic and has a certain degree of deformation. The bottom of the lower cover is a flat structure for accommodating magnets, with a hole in the middle for air release or a sealed structure.

[0028] The thickness of the first thin wall 12 is between 0.5-2 mm, and the thickness of the second thin wall 22 is between 1-2 mm. If it is too thin, it is easy to break, and if it is too thick, it is not easy to deform. The thickness of the first locking structure 11 is greater than 0.3 mm. If it is too thin, the first locking structure 11 is easy to break. The accommodation depth of the second locking structure 21 is greater than 0.4 mm, and is used to engage with the first locking structure 11.

[0029] An upper magnetic circuit 3, a diaphragm 4, a voice coil 5 and a lower magnetic circuit 6 are arranged in sequence from top to bottom in the space enclosed by the upper cover 1 and the lower cover 2.

[0030] In this embodiment, the first locking structure 11 is a locking strip protruding from the outer wall of the upper cover 1, and the locking strip includes a first contact surface 111 and a second contact surface 112. The first contact surface 111 is in contact with the buckling surface 211. Under the resistance of the buckling surface 211, the first contact surface 111 cannot be separated from the second locking structure 21, thereby preventing the upper cover 1 and the lower cover 2 from falling off. The angle between the first contact surface 111 and the second contact surface 112 is an acute angle of 80-90°, and the acute angle is rounded. An inward groove can be provided on the second contact surface 112. During installation, the groove can assist deformation to facilitate the installation of the first locking structure 11. When the first locking structure 11 is subjected to upward force, it is pushed to deform in the opposite direction, increasing the width of the first locking structure 11, thereby preventing the upper cover 1 from falling off.

[0031] In this embodiment, the second locking structure 21 also includes a contact surface 212. The contact surface 212 and the buckling surface 211 form a concave locking groove. The inner corner of the locking groove is a pointed structure. The first locking structure 11 is engaged with the locking groove, and the contact surface 212 is in contact with the second contact surface 112. The upper cover 1 and the lower cover 2 are fixed by a double-sided bonding method. The upper cover 1 has better support, can prevent the upper cover 1 from shaking, and avoid the upper cover 1 from loosening.

[0032] Working process: Install the upper magnetic circuit 3, diaphragm 4, voice coil 5 and lower magnetic circuit 6 into the lower cover 2 in reverse order, and press the first locking structure 11 into the second locking structure 21 to complete the installation.

[0033] Example 2:

[0034] Combine Figure 4-Figure 5 In this embodiment, the first locking structure 11 is a locking strip protruding from the outer wall of the upper cover 1. The locking strip includes a third contact surface 113 and a first supporting surface 114. The third contact surface 113 is in contact with the buckling surface 211. The first locking structure 11 is only in contact with the buckling surface 211 through the third contact surface 113. The buckling surface 211 limits the first locking structure 11 from above. The angle between the third contact surface 113 and the first supporting surface 114 is an acute angle of 30-50°.

[0035] In this embodiment, the second locking structure 21 also includes a second supporting surface 213. The second supporting surface 213 and the locking surface 211 constitute a convex strip with a triangular cross-section protruding from the inner wall of the lower cover 2. The second locking structure 21 supports the top of the first locking structure 11, and the slope of the locking surface 211 is gentler, providing greater support force on the third contact surface 113.

[0036] In this embodiment, the third contact surface 113 and the locking surface 211 are provided with wedge-shaped grooves that match each other, and the wedge-shaped grooves on the third contact surface 113 and the locking surface 211 are hooked together, thereby increasing the surface area of ​​the third contact surface 113 and the locking surface 211, thereby improving the contact surface between the two.

[0037] In this embodiment, other structures are the same as those in the first embodiment.

[0038] Example 3:

[0039] Combine Figure 6-Figure 7 In this embodiment, the first locking structure 11 is a locking strip flush with the surface of the upper cover 1. A fourth contact surface 115 and a vertical surface 116 are provided on the locking strip. The fourth contact surface 115 contacts the buckling surface 211. The fourth contact surface 115 is a planar structure, and the angle between the fourth contact surface 115 and the vertical surface 116 is a right angle.

[0040] In this embodiment, the second locking structure 21 also includes a third supporting surface 214, the angle between the third supporting surface 214 and the locking surface 211 is a right angle, the vertical surface 116 is close to the third supporting surface 214, the third supporting surface 214 and the locking surface 211 completely wrap the fourth contact surface 115 and the vertical surface 116, and the second locking structure 21 and the first locking structure 11 are offset by plane, which has better stability.

[0041] In this embodiment, the fourth contact surface 115 and the locking surface 211 are both rough surfaces, which increase friction while improving the stability of the upper cover 1 and the lower cover 2. Moreover, because the fourth contact surface 115 is a planar structure, it is equivalent to an extension of the upper cover 1, so that the upper cover 1 is completely embedded in the lower cover 2 after installation, reducing the external force on the upper cover 1.

[0042] In this embodiment, the first thin wall 12 and the first engaging structure 11 can be understood as an integral structure, and other structures are the same as those in the first embodiment.

[0043] To sum up: the utility model is a simple snap-on speaker, the upper cover 1 and the lower cover 2 adopt a snap-on structure, the snap-on structure includes a first snap-on structure 11 arranged on the outer wall of the upper cover 1 and a second snap-on structure 21 arranged on the inner wall of the lower cover 2, wherein the second snap-on structure 21 provides a snap-on surface 211 which is abutted against the second snap-on structure 21 to fasten the position of the upper cover 1. When the upper cover 1 and the lower cover 2 are assembled, the upper cover 1 and the lower cover 2 are snapped together by pressing, which makes the assembly more convenient. The first thin wall 12 and the second thin wall 22 provide deformation space for it. Compared with gluing and fixing, which requires waiting for the glue to dry, this hook-on matching method can increase the efficiency by 80%, and the combination is more firm. Glue can also be applied before installation to increase the overall firmness. Because of the clamping of the snap-on structure, there is no need to wait for the glue to dry.
