[0001] This utility model belongs to the field of electroacoustic product technology, and in particular relates to a loudspeaker and loudspeaker device. Background Technology

[0002] With the development of technology, loudspeakers are being used in more and more scenarios, such as car loudspeakers and smart TV loudspeakers.

[0003] Currently, the wiring terminals used for electrical connections are located on the outside of the speaker housing and embedded inside the housing. The wiring terminals have electrical connection parts that protrude outside the housing at the corresponding points of the speaker's wires and the wiring harness that connects to the motherboard, making it easy for the speaker's wires and wiring harness to be electrically connected to the wiring terminals. This structure is complex and occupies a lot of space. Moreover, when product upgrades or changes in usage requirements require the replacement of wiring terminals with different structures, the molds for producing the housing need to be redesigned because the wiring terminals are embedded inside the housing, which increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a loudspeaker and loudspeaker device, which aims to solve the problems of large space occupation caused by pre-embedded wiring terminals on the outside of the loudspeaker housing and increased production costs caused by the need to redesign and produce housing molds when replacing wiring terminals with different structures.

[0005] This utility model discloses a loudspeaker, which includes a housing forming a accommodating cavity, a positioning ring, and a sound-generating module fixedly installed on the positioning ring. The positioning ring and the sound-generating module are fixedly installed inside the accommodating cavity, and a circumferential positioning structure is provided between the positioning ring and the housing. It also includes at least two terminals spaced apart along the outer periphery of the positioning ring and corresponding one-to-one with the filaments of the sound-generating module. Each terminal includes a plug portion inserted into the outer periphery of the positioning ring along the axial direction of the positioning ring, an extension portion connected to the plug portion and extending out of the housing, and a clamping portion provided in the plug portion. The filaments are fixed to the plug portion by the clamping portion.

[0006] As an improvement, the housing includes an annular outer shell, the front port of which forms a sound outlet, and a pressure ring fixedly installed at the rear port of the annular outer shell, forming an accommodating cavity between the pressure ring and the front port.

[0007] As an improvement, the insertion portion and the extension portion are bent together, with the extension portion extending out from between the pressure ring and the rear port.

[0008] As an improvement, the outer periphery of the positioning ring is provided with a boss, and a receiving groove is provided on the boss corresponding to each of the terminals. Insertion grooves are provided on the two side walls of the receiving grooves, and the two sides of the insertion part are respectively inserted into the corresponding insertion grooves. The inner side wall of the annular shell is provided with a positioning groove that matches the boss, and the boss and the positioning groove form the circumferential positioning structure.

[0009] As an improvement, the receiving groove is provided with an open end on one side corresponding to the rear port, and the receiving groove is provided with a closed end on one side corresponding to the front port.

[0010] As an improvement, a support groove is provided at the rear port, and a cover plate adapted to the support groove is provided on the pressure ring, with the extension clamped between the cover plate and the bottom surface of the support groove.

[0011] As an improvement, a partition for locking between two adjacent terminals is provided on the bottom surface of the support groove.

[0012] As an improvement, the plug portion and the extension portion of the terminal block are arranged in a straight line, and a serial hole is provided on the pressure ring corresponding to the extension portion, through which the extension portion passes.

[0013] As an improvement, the clamping part is a die-cutting plate protruding from the insertion part and is disposed in the middle of the insertion part.

[0014] This utility model also discloses a loudspeaker device, which includes the loudspeaker and a wiring harness. The wiring harness has wires that correspond one-to-one with the terminals. Each wire at one end of the wiring harness has a quick-connect terminal at its end and a connector at the other end of the wiring harness. Each wire is connected to the connector.

[0015] The beneficial effects achieved by adopting the above technical solution are as follows:

[0016] The loudspeaker of this invention includes a housing forming a accommodating cavity, a positioning ring, and a sound-generating module fixedly mounted on the positioning ring. The positioning ring and the sound-generating module are fixedly mounted inside the accommodating cavity, and a circumferential positioning structure is provided between the positioning ring and the housing. It also includes at least two terminals spaced apart along the outer periphery of the positioning ring and corresponding one-to-one with the filaments of the sound-generating module. Each terminal includes a plug portion inserted into the outer periphery of the positioning ring along the axial direction of the positioning ring, an extension portion connected to the plug portion and extending out of the housing, and a clamping portion provided in the plug portion. The filaments are fixed to the plug portion by the clamping portion. The loudspeaker device of this invention includes a loudspeaker and a wiring harness. The wiring harness has wires corresponding one-to-one with the terminals. Each wire at one end of the wiring harness has a quick-connect terminal, and a connector at the other end of the wiring harness. Each wire is connected to the connector.

[0017] During assembly, the magnetic circuit system and vibration system of the sound-generating module are fixedly installed on the positioning ring. The wires of the sound-generating module are then fixed to the plug-in part via the clamping part, achieving electrical connection between the sound-generating module and the terminal block. The positioning ring and sound-generating module are then fixedly installed inside the housing cavity, allowing the extensions of the terminal blocks to protrude from the housing for easy electrical connection. The installed positioning ring is located inside the housing cavity. Because the plug-in part of the terminal block is inserted into the outer circumference of the positioning ring, only the extension can protrude from the housing, thus reducing space occupation. Furthermore, since the plug-in part of the terminal block is inserted into the outer circumference of the positioning ring, when different terminal block structures are required, only the corresponding plug-in structure needs to be designed on the terminal block, without changing the structure of the housing. This eliminates the need to redesign and produce the housing mold, reducing production costs. This solves the problems of large space occupation due to pre-embedded terminal blocks on the outside of the speaker housing and increased production costs due to the need to redesign and produce the housing mold when changing to different terminal block structures.

[0028] It should be noted that if the directional indications (such as up, down, front, back, etc.) involved in this utility model are only used to explain the relative positional relationship between the components in a certain specific posture, the directional indications will change accordingly if the specific posture changes; if the descriptions of "first", "second", etc. involved in this utility model are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0029] Depend on Figures 1 to 6 As can be seen, the loudspeaker of this utility model includes a housing forming a accommodating cavity, a positioning ring 20, and a sound-generating module 10 fixedly installed on the positioning ring 20. The positioning ring 20 and the sound-generating module 10 are fixedly installed inside the accommodating cavity. A circumferential positioning structure is provided between the positioning ring 20 and the housing. Specifically, the sound-generating module 10 includes a magnetic circuit system and a vibration system respectively fixedly installed on the positioning ring 20. The voice coil of the vibration system is inserted into the magnetic gap of the magnetic circuit system. The voice coil is made of nylon wire. 11 is formed by winding; it also includes at least two terminals 30 spaced apart along the outer periphery of the positioning ring 20, each terminal 30 including a plug portion 31 inserted into the outer periphery of the positioning ring 20 along the axial direction of the positioning ring 20, an extension portion 32 connected to the plug portion 31 and passing through the housing, and a clamping portion 33 provided in the plug portion 31. The brocade wire 11 of the sound-generating module 10 is fixed to the plug portion 31 by the clamping portion 33, wherein the extension portion 32 passes through the housing to realize electrical connection.

[0030] During assembly, the magnetic circuit system and vibration system of the sound-generating module 10 are fixedly installed on the positioning ring 20, and the filament wire 11 of the sound-generating module 10 is fixed to the plug-in part 31 through the clamping part 33 to realize the electrical connection between the sound-generating module 10 and the terminal block 30. Then, the positioning ring 20 and the sound-generating module 10 are fixedly installed inside the accommodating cavity, so that the extension part 32 of the terminal block 30 protrudes out of the housing to facilitate the electrical connection. After installation, the positioning ring 20 is located inside the housing cavity. Since the insertion part 31 of the terminal block 30 is inserted into the outer periphery of the positioning ring 20, only the extension part 32 can protrude from the housing, thereby reducing the space occupied. At the same time, since the insertion part 31 of the terminal block 30 is inserted into the outer periphery of the positioning ring 20, when different terminal block structures are required, only the corresponding insertion structure needs to be designed on the terminal block, without changing the structure of the housing, and therefore without redesigning the mold for producing the housing, which can reduce production costs. The speaker of this utility model solves the problems of large space occupation caused by the terminal block being pre-embedded on the outside of the speaker housing and the increased production costs caused by the need to redesign the mold for producing the housing when replacing different terminal block structures.

[0031] In this utility model, the housing includes an annular outer shell 40, the front port of the annular outer shell 40 forms a sound outlet, and also includes a pressure ring 50 fixedly installed at the rear port of the annular outer shell 40, forming an accommodating cavity between the pressure ring 50 and the front port. The pressure ring 50 is used to fix the sound-generating module 10 and the positioning ring 20 installed together between the pressure ring 50 and the front port of the annular outer shell 40.

[0032] Specifically, the insertion portion 31 and the extension portion 32 of the terminal block 30 are bent together, and the extension portion 32 extends out from between the pressure ring 50 and the rear port of the annular housing 40. Preferably, the insertion portion 31 and the extension portion 32 are arranged perpendicularly.

[0033] During assembly, the positioning ring 20 and the sound-generating module 10, which are installed together, are inserted into the receiving cavity from the rear port of the annular housing 40. The extension 32 of the wiring terminal 30 extends from the side of the rear port of the annular housing 40 to the outside of the annular housing 40. Then, the pressure ring 50 is fixedly installed at the rear port of the annular housing 40, and the positioning ring 20 and the sound-generating module 10 are confined between the pressure ring 50 and the front port of the annular housing 40. Typically, a retaining ring is provided on the inner ring side of the front port of the annular housing 40, and the peripheral side of the sound-generating module 10 is confined between the positioning ring 20 near the front port of the annular housing 40 and the retaining ring. The pressure ring 50, which is fixedly installed at the rear port of the annular housing 40, presses against the positioning ring 20 near the rear port of the annular housing 40.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, a support groove 41 is provided at the rear port of the annular housing 40, and a cover plate 51 adapted to the support groove 41 is provided on the pressure ring 50. The extension 32 of the terminal 30 is clamped between the cover plate 51 and the bottom surface of the support groove 41. Specifically, a partition 42 is provided on the bottom surface of the support groove 41 to lock between two adjacent terminals 30, preventing short circuits between adjacent terminals 30, and also providing support for the cover plate 51.

[0035] like Figure 3 , Figure 4 and Figure 6 As shown, the clamping part 33 is a die-cut pressure plate protruding from the plug-in part 31 and is located in the middle of the plug-in part 31. It can reduce the impact on the strength of the plug-in part 31 and avoid affecting the plug-in installation of the terminal block 30. During assembly, the nylon wire 11 of the sound-generating module 10 is clamped between the clamping part 33 and the plug-in part 31, and then the clamping part 33 is squeezed to deform it, so as to fix the nylon wire 11.

[0036] In some other embodiments, the insertion portion 31 and the extension portion 32 of the terminal block 30 are arranged in a straight line, and a serial hole is provided on the pressure ring 50 corresponding to the extension portion 32, through which the extension portion 32 passes.

[0037] In this utility model, a boss 22 is provided on the outer periphery of the positioning ring 20. A receiving groove 23 is provided on the boss 22 corresponding to each terminal 30. Insertion grooves 24 are provided on the two side walls of the receiving grooves 23. The two sides of the insertion part 31 are respectively inserted into the corresponding insertion grooves 24.

[0038] Specifically, the receiving groove is set as an open end on one side of the rear port of the annular housing 40, and the receiving groove is set as a closed end on one side of the front port of the annular housing 40.

[0039] like Figure 6 As shown, in order to prevent the terminal block 30 from coming out after installation, one-way locking teeth 34 are provided on opposite sides of the plug-in part 31. A locking groove (not shown in the figure) that matches the one-way locking teeth 34 is provided on the bottom surface of the plug-in groove 24. The one-way locking teeth 34 is provided with a locking surface on one side of the opening end of the receiving groove and a guide slope on one side of the closing end of the receiving groove, so that the terminal block 30 can be inserted and cannot be pulled out after insertion.

[0040] Correspondingly, the inner wall of the annular outer shell 40 is provided with a positioning groove that matches the boss 22. The boss 22 and the positioning groove form a circumferential positioning structure, which can be positioned by the cooperation between the boss 22 on the positioning ring 20 and the positioning groove on the inner wall of the annular outer shell 40.

[0041] To facilitate the routing of the brocade thread 11, a wire groove 21 is provided at the front port of the annular housing 40 corresponding to each receiving groove.

[0042] In this invention, two terminals 30 are provided, and the two nylon wires 11 of the sound-generating module 10 are respectively connected to the two terminals 30. Of course, some sound-generating modules 10 are provided with three nylon wires 11, then the corresponding terminals 30 are also provided with three.

[0043] Depend on Figure 7 It is understood that this utility model also discloses a speaker device, which includes the aforementioned speaker and a wiring harness. The wiring harness has wires 60 corresponding one-to-one with the terminals 30. Each wire 60 near the end of the wiring harness has a quick-connect terminal 61 at its end, and a connector (not shown in the figure) is provided at the end of the wiring harness away from the speaker. Each wire 60 is connected to the connector. During electrical connection, the quick-connect terminal 61 of the wire 60 is inserted into the extension 32 of the terminal 30, and then electrically connected to the motherboard of a car, smart TV, etc., through the connector.

[0044] Since the positioning ring 20 is located inside the housing cavity after installation, the insertion part 31 of the terminal block 30 is inserted into the outer periphery of the positioning ring 20, with only the extension part 32 able to protrude from the housing, thus reducing the space occupied. Because the insertion part 31 of the terminal block 30 is inserted into the outer periphery of the positioning ring 20, when different terminal block structures are required, only the corresponding insertion structure needs to be designed on the terminal block, without changing the structure of the housing, and therefore without needing to redesign the housing mold, reducing production costs. This solves the problems of large space occupation due to the terminal block being pre-embedded on the outside of the speaker housing and increased production costs due to the need to redesign the housing mold when replacing different terminal block structures. Simultaneously, the nylon wire 11 of the sound-generating module 10 is electrically connected to the terminal block 30 by crimping, and the wire 60 and terminal block 30 are electrically connected by plugging, eliminating the need for soldering, making installation convenient.

[0045] The above description is only some embodiments of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
