Description

Technical Field

[0001] The utility model relates to the technical field of electroacoustic converters, in particular to a loudspeaker module. Background Art

[0002] With the continuous development of electronic technology, the performance requirements of portable electronic devices are getting higher and higher, and electronic devices need to be compatible with more and more functions. In addition to the electroacoustic conversion function, some speaker modules also need to have a grounding function. This grounding function is sometimes used to ground the antenna inside the electronic device, and sometimes to conduct static electricity inside the electronic device to the ground.

[0003] At present, this type of speaker module with a grounding function generally requires a grounding spring clip to be clamped on the module housing. Specifically, a clamping hole is provided on the grounding spring clip, and a clamping column that cooperates with the clamping hole is provided on the module housing. However, when the automated equipment assembles the grounding spring clip on the module housing, the edge of the grounding spring clip can easily shorten or flatten the clamping column, making the grounding spring clip not well fixed. Later, during packaging or transportation, the grounding spring clip can easily fall off from the module housing, seriously affecting the structural stability of the speaker module. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a loudspeaker module with a stable structure.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a speaker module, comprising:

[0006] A module housing, wherein the module housing has a tongue plate, and a clamping column is provided on the tongue plate;

[0007] A grounding spring, the grounding spring having an inserting slot and a clamping hole connected to the inserting slot, the clamping hole being engaged with the clamping post, the edge of the grounding spring having a warped portion, and the warped portion having a first guide surface on a side close to the tongue plate;

[0008] During the process of inserting the tongue plate into the inserting slot, the first guide surface and the clamping column are in sliding contact to expand the opening of the inserting slot outward.

[0009] Furthermore, the first guiding surface is an inclined surface or a curved surface.

[0010] Furthermore, the end of the clamping column is provided with a second guide surface for contacting the first guide surface.

[0011] Furthermore, the grounding spring plate includes a first plate, a second plate and a third plate connected in sequence, the first plate is arranged parallel to the third plate, the first plate, the second plate and the third plate are combined to form the plug-in slot, and the first plate and / or the third plate are provided with the snap-in hole.

[0012] Furthermore, there are multiple second plates, and each second plate is connected to the third plate.

[0013] Furthermore, the tongue plate is located at a corner, a long side or a short side of the module housing.

[0014] Furthermore, the edge of the tongue plate is chamfered.

[0015] Furthermore, a contact protrusion is provided on the grounding elastic piece.

[0016] Furthermore, a through hole is provided on the tongue plate, and a through hole communicating with the through hole is provided on the grounding elastic piece.

[0017] Furthermore, the module housing has an inner recess, and the tongue plate is located in the inner recess.

[0018] The beneficial effect of the present invention is that: in the speaker module, the grounding spring has a warped portion. During the process of installing the grounding spring on the module housing, after the warped portion contacts the end of the clamping column, the warped portion can guide the opening of the plug-in slot of the grounding spring to expand outward, so that the clamping column can be more smoothly inserted into the clamping hole, thereby realizing the clamping connection between the grounding spring and the module housing. In this process, due to the existence of the warped portion, the edge of the grounding spring will not shorten or flatten the clamping column, which effectively ensures the stability of the clamping connection between the grounding spring and the module housing, reduces the risk of the grounding spring accidentally falling off from the module housing, and is beneficial to improving the structural stability of the speaker module.

[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0027] Please refer to Figures 1 to 3 , a speaker module, comprising:

[0028] A module housing 1 having a tongue plate 11 on which a clamping column 12 is provided;

[0029] A grounding spring 3 having an insertion slot 31 and a latching hole 32 communicating with the insertion slot 31 . The latching hole 32 engages with the latching post 12 . The edge of the grounding spring 3 has a warped portion 33 . The warped portion 33 has a first guide surface 331 on a side close to the tongue plate 11 .

[0030] When the tongue plate 11 is inserted into the inserting slot 31 , the first guide surface 331 is in sliding contact with the clamping post 12 to expand the opening of the inserting slot 31 outward.

[0031] From the above description, it can be seen that the beneficial effect of the present invention is that: in the present speaker module, the grounding spring clip 3 has a warped portion 33. During the process of installing the grounding spring clip 3 on the module housing 1, after the warped portion 33 contacts the end of the clamping column 12, the warped portion 33 can guide the opening of the plug-in slot 31 of the grounding spring clip 3 to expand outward, so that the clamping column 12 can be more smoothly inserted into the clamping hole 32, thereby realizing the clamping of the grounding spring clip 3 and the module housing 1. In this process, due to the presence of the warped portion 33, the edge of the grounding spring clip 3 will not shorten or flatten the clamping column 12, effectively ensuring the stability of the clamping between the grounding spring clip 3 and the module housing 1, reducing the risk of the grounding spring clip 3 accidentally falling off from the module housing 1, and helping to improve the structural stability of the speaker module.

[0032] Furthermore, the first guiding surface 331 is an inclined surface or a curved surface.

[0033] As can be seen from the above description, the specific structure of the first guide surface 331 can be selected as needed.

[0034] Furthermore, a second guide surface 121 for contacting the first guide surface 331 is provided at the end of the clamping column 12 .

[0035] From the above description, it can be seen that the existence of the second guide surface 121 can set the effective height of the clamping column 12 higher, thereby greatly reducing the risk of the grounding spring 3 accidentally detaching from the tongue plate 11, and further improving the structural stability of the speaker module.

[0036] Furthermore, the grounding spring 3 includes a first plate 34, a second plate 35 and a third plate 36 connected in sequence, the first plate 34 and the third plate 36 are arranged in parallel, the first plate 34, the second plate 35 and the third plate 36 enclose the plug-in slot 31, and the first plate 34 and / or the third plate 36 are provided with the snap-in hole 32.

[0037] As can be seen from the above description, the overall structure of the grounding spring 3 is simple, and the grounding spring 3 and the tongue plate 11 can be connected by either single-sided or double-sided clamping, which can be specifically configured as needed.

[0038] Furthermore, there are multiple second plates 35 , and each second plate 35 is connected to the third plate 36 .

[0039] As can be seen from the above description, providing multiple second plates 35 and third plates 36 can reduce the overall rigidity of the grounding spring 3, and prevent the plug-in slot 31 from being difficult to expand outward when the grounding spring 3 is assembled with the tongue plate 11, so that a greater force is required to assemble the grounding spring 3 to the tongue plate 11. If a greater force is used to assemble the grounding spring 3, the risk of the grounding spring 3 shortening or flattening the positioning column will be increased.

[0040] Furthermore, the tongue plate 11 is located at a corner, a long side or a short side of the module housing 1 .

[0041] It can be seen from the above description that the specific position of the tongue plate 11 on the module housing 1 can be set as needed.

[0042] Furthermore, the edge of the tongue plate 11 is provided with a chamfer 111 .

[0043] As can be seen from the above description, the chamfer 111 can provide guidance for the grounding spring piece 3 when assembling the grounding spring piece 3 , so that the grounding spring piece 3 can be more smoothly engaged with the tongue plate 11 .

[0044] Furthermore, a contact protrusion 37 is provided on the grounding elastic piece 3 .

[0045] As can be seen from the above description, the contact protrusion 37 on the grounding spring 3 enables the grounding spring 3 to be in contact and conductive with the external device more stably.

[0046] Furthermore, a through hole 112 is provided on the tongue plate 11 , and a through hole 38 communicating with the through hole 112 is provided on the grounding elastic piece 3 .

[0047] As can be seen from the above description, after the grounding spring 3 is snapped onto the tongue plate 11 , the through hole 112 is connected to the through hole 38 to form a mounting hole, so that the external structural component can be fixedly connected to the speaker module via the mounting hole.

[0048] Furthermore, the module housing 1 has an inner recess 13 , and the tongue plate 11 is located in the inner recess 13 .

[0049] As can be seen from the above description, the presence of the inner recess 13 can prevent the provision of the tongue plate 11 from causing the overall outline size of the speaker module to become larger, which is conducive to ensuring the miniaturization of the speaker module.
