Description

Technical Field

[0001] The invention relates to the technical field of sound box equipment, and in particular to a high-compatibility plug-in component for a loudspeaker. Background Art

[0002] The speaker is a very common sound transmission device in people's production and life. It is a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the speaker's high-compatibility plug-in component will move forward or backward, so the paper plate of the speaker's high-compatibility plug-in component will move with it. This action causes the density of the air to change and produce sound.

[0003] In order to increase the bandwidth and volume of the speaker, multiple sub-speakers with different frequencies and volumes are often set in one speaker. However, with the improvement of people's living standards, the size of the speaker is often required to be smaller and smaller. However, in the prior art, the tweeter is directly soldered on the circuit board, but because the size of the entire speaker is getting smaller and smaller, the soldering piece of the tweeter is very short. When inserted into the circuit board, the body of the tweeter is already close to the circuit board, making it impossible to solder. In addition, in the actual production of speakers, in order to reduce costs and improve production efficiency, the compatibility of various components is very important, that is, while solving the problem of short soldering pieces, the assembly of the original tweeter with long soldering pieces must also be taken into account. Summary of the invention

[0004] In view of this, the present invention provides a high-compatibility plug-in assembly for assembling speakers that is compatible with multiple types of secondary speakers to solve the above-mentioned problem.

[0005] A high-compatibility plug-in assembly for a loudspeaker comprises a circuit board, at least one plug spring inserted on the circuit board, and a loudspeaker bracket inserted on the plug spring. The circuit board is provided with at least two through holes corresponding to the plug-in components and comprises a front side and a back side opposite to the front side. The plug spring is fixedly arranged on the back side of the circuit board and comprises a body, two inserting knives arranged on the body at intervals, and two abutting members arranged on the body at intervals. The body is provided with a through hole. The through hole is opposite to the through hole. The two inserting knives are arranged on both sides of the through hole of the body and the extending direction of the inserting knives is perpendicular to the plane where the through hole is located. The arrangement direction of the two abutting members is perpendicular to the arrangement direction of the two inserting knives and the two abutting members are arranged in mirror symmetry. The abutting member comprises a connecting portion connected to the body, an abutting top portion connected to the connecting portion, and an introduction portion connected to the abutting top portion. The connecting portion is an arc so that the two abutting top portions are arranged opposite to each other and have elasticity. The introduction portion extends from the abutting top portion and extends toward the connecting portion. The introduction portion extends into the through hole on the body. The speaker bracket includes two soldering pieces arranged at intervals. The soldering piece is inserted between the two abutting tops through the through hole from the front side of the circuit board or inserted between the two abutting tops from the back side of the circuit board.

[0006] Furthermore, the speaker bracket also includes a bracket, and the bracket includes a connecting ring and two inserting handles arranged on the connecting ring, and the welding piece is inserted and fixed in the inserting handles.

[0007] Furthermore, the bracket is made of non-metal.

[0008] Furthermore, the two inserting blades of the inserting spring are inserted and fixed on the circuit board and welded on the circuit board.

[0009] Furthermore, the two connecting parts of the plug spring are arranged toward the circuit board.

[0010] Furthermore, the two abutting top portions are spaced apart from each other, and a minimum distance between the two abutting top portions is smaller than a thickness of the welding sheet.

[0011] Furthermore, the through hole is rectangular, and the length of the through hole is smaller than the axial length of the abutting member.

[0012] Furthermore, when the welding piece is inserted into the through hole from the front side of the circuit board and inserted into the abutting member, the end of the welding piece is welded to the two introduction parts.

[0013] Furthermore, the two inserting knives are arranged on both sides of the through hole of the body and the extending direction of the inserting knives is perpendicular to the plane where the through hole is located.

[0014] Furthermore, the arrangement direction of the two abutting members is perpendicular to the arrangement direction of the two inserting knives.

[0015] Compared with the prior art, the high-compatibility plug-in assembly of the speaker provided by the present invention is provided with a perforation on the circuit board and a plug spring arranged on the circuit board, so that the soldering piece of the speaker bracket can be inserted into the plug spring from the front side of the circuit board or from the back side of the circuit board. When the soldering piece of the speaker bracket is inserted from the back side of the circuit board, since there are no large electronic components arranged on the back side of the circuit board, the size of the soldering piece of the speaker bracket can be designed to be the shortest. When the soldering piece of the speaker bracket is relatively long, it can be selected to be inserted into the plug spring from the front side of the circuit board through the perforation of the circuit board, thereby improving the compatibility of the plug-in assembly. In order to fix the soldering piece inserted from the front or back side of the circuit board, the body of the plug spring has a through hole corresponding to the perforation, and the introduction part of the abutting member extends into the through hole, and the two introduction parts are arranged opposite to each other, so that the soldering piece can be inserted between the abutting tops from the introduction part or from the arc-shaped connecting part. At the same time, due to the presence of the two abutting tops, the plug spring and the welding piece are fixed, and the use of solder for welding can be avoided. Therefore, even if the length of the welding piece is the shortest, as long as the plug spring can be inserted and fixed by the abutting top, it is sufficient. It is also because no solder welding is required that the length of the welding point can be designed to be the shortest, which is undoubtedly conducive to reducing the volume of the entire speaker. Of course, it is undoubtedly easier to complete the plug-in fixation for a longer welding piece, so as to achieve compatibility with secondary speakers with welding pieces of different lengths.

[0019] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0020] like Figures 1 to 3As shown, it is a schematic diagram of the structure of a high-compatibility plug assembly of a speaker provided by the present invention. The high-compatibility plug assembly of the speaker includes a circuit board 10, at least one plug spring 20 plugged on the circuit board 10, and a speaker bracket 30 plugged on the plug spring 20. It can be imagined that the speaker also includes some other functional modules, such as a heat dissipation module, an electrical connection component, a mechanical assembly component, a housing, etc., which are well known to those skilled in the art and will not be described in detail here.

[0021] It should also be noted that the speaker is composed of a plurality of sub-speakers, which may be composed of a woofer sub-speaker and a tweeter sub-speaker, or may be composed of only a woofer sub-speaker or only a tweeter sub-speaker. They can be arranged according to actual needs and will not be described in detail here.

[0022] The circuit board 10 itself is a prior art, and is used to provide various circuits. Of course, it is conceivable that the circuit board 10 is also provided with various electronic components, such as resistors, capacitors, inductors, transformers, etc. The circuit board 10 is used to plug in a tweeter or a woofer to provide it with a rated voltage or control signal, etc., which is a prior art and will not be repeated here. In order to distinguish the two sides of the circuit board 10, the circuit board 10 includes a front side 11, a back side 12 with the front side 11, and at least two through holes 13 that penetrate the front side 11 and the back side 12. The electronic components, such as resistors, capacitors, inductors, transformers, etc. are arranged on the front side 11. The plug spring 20 is arranged on the back side 12 to avoid the various electronic components arranged on the front side 11, so that the sub-speaker is arranged on the back side 12, and then the length of the welding piece 32 of the speaker bracket 30 can be designed to be the shortest. The through hole 13 is used for when the soldering piece 32 of the speaker bracket 30 is arranged on the front side 11 of the circuit board 10, the soldering piece 32 passes through the through hole 13 to be inserted into the plug spring 20. In order to adapt to the shape of the soldering piece 32 described below, the through hole 13 is rectangular. Therefore, the through hole 13 corresponds to the plug spring 20, which will be described in detail below.

[0023] The number of the plug springs 20 is set according to actual needs, but there should be at least two for inserting the positive and negative poles of a secondary speaker. The plug spring 20 can be integrally formed, specifically, it can be stamped. The position of the plug spring 20 corresponds to the position of the through hole 13, and it includes a body 21, two insert blades 22 arranged at intervals on the body 21, and two abutment members 23 arranged at intervals on the body 21. The body 21 is used to connect the insert blades 22 and the abutment members 23, and the body 21 is provided with a through hole 24. The through hole 24 is aligned with the through hole 13 so that the soldering piece 32 can pass through the through hole 13 and the through hole 24 to achieve the purpose of fixing. The two insert blades 22 are arranged on both sides of the body 21, specifically, the two insert blades 22 are arranged on both sides of the through hole 24 of the body 21 and the extension direction of the insert blade 22 is perpendicular to the plane where the through hole 24 is located, so that the body 21 is parallel to the plane where the circuit board 10 is located. Of course, it is conceivable that the insert blade 22 is inserted into the circuit board 10, and is electrically connected to the circuit on the circuit board 10 and is soldered together by solder. The insert blade 22 can be set according to actual needs, such as being in the shape of a sharp knife, or being provided with a clamping structure, which will not be repeated here. The arrangement direction of the two abutting members 23 is perpendicular to the arrangement direction of the two insert blades 22, and the two abutting members 23 are arranged in a mirror-symmetrical manner, which is beneficial to saving materials and is also beneficial to manufacturing the insert spring 20. The two abutting members 23 are arranged in a mirror-symmetrical manner to facilitate forming a gap to clamp the welding piece 32. Each of the abutting members 23 includes a connecting portion 231 connected to the body 21, an abutting top portion 232 connected to the connecting portion 231, and an introduction portion 233 connected to the abutting top portion 232. The connecting portion 231 is an arc so that the two abutting top portions 232 are arranged opposite to each other and have elasticity. The arc shape of the connecting portion 231 also allows the introduction portion 233 to extend toward the through hole 24. Since the connecting portion 231 is arc-shaped, the minimum distance between the two connecting portions 231 is the abutting top portion 232. The inserting blade 22 and the abutting member 23 are arranged on the same side of the body 21, so that the two connecting portions 231 of the insertion spring 20 are arranged toward the circuit board 10. The abutting top portion 232 is used to clamp the soldering piece 32, so the minimum distance between the two abutting top portions should be less than the thickness of the soldering piece 32. The introduction portion 233 extends from the abutting top portion 232 and extends toward the connecting portion 231, so that the maximum distance between the two introduction portions 233 is greater than the thickness of the soldering piece 32, and thus when the soldering piece 32 is inserted from the reverse side 12 of the circuit board 10, it is more convenient to insert and avoid mistakes. The axial length of the abutting member 23 is greater than the length of the through hole 13, so as to avoid the soldering piece 32 from being inserted crookedly into the inserted spring 20 and causing poor contact, such as only part of the soldering piece contacting the insertion spring 20.

[0024] The speaker bracket 30 includes a bracket 31 and two welding pieces 32 respectively fixed on the bracket 31. The bracket 31 is a part of the speaker, and its structure and shape can be set according to actual needs. In this embodiment, the bracket 31 includes a connecting ring 311 and two plug handles 312 arranged on the connecting ring 311. The welding piece 32 is inserted and fixed in the plug handle 312. Of course, it is conceivable that the welding piece 32 is also electrically connected to other components of the speaker, such as a coil, etc., through a wire. The welding piece 32 should be made of metal.

[0025] When the speaker bracket 30 is inserted into the insertion spring 20, the soldering piece 32 can be inserted from the front side 11 of the circuit board 10 through the through hole 13 and between the two abutting parts 232, or inserted from the back side 12 of the circuit board 10 between the two abutting parts 232. When the soldering piece 32 is inserted from the front side 11 of the circuit board 10 into the through hole 13 and inserted into the abutting part 232, the end of the soldering piece 32 can be welded to the two introduction parts 233.

[0026] Compared with the prior art, the high-compatibility plug-in assembly of the speaker provided by the present invention is provided with a through hole 13 on the circuit board 10 and a plug spring 20 arranged on the circuit board 10, so that the soldering piece 32 of the speaker bracket 30 can be inserted into the plug spring 20 from the front side of the circuit board 10, or can be inserted into the plug spring 20 from the back side 12 of the circuit board 10. When the soldering piece 32 of the speaker bracket 30 is inserted from the back side 12 of the circuit board 10, since there is no large electronic component arranged on the back side 12 of the circuit board 10, the size of the soldering piece 32 of the speaker bracket 30 can be designed to be the shortest. When the soldering piece 32 of the speaker bracket 30 is relatively long, it can be selected to be inserted into the plug spring 20 from the front side 11 of the circuit board 10 through the through hole 13 of the circuit board 10, thereby improving the compatibility of the plug-in assembly. In order to fix the soldering piece 32 inserted from the front side 11 or the back side 12 of the circuit board 10, the body 21 of the plug spring 20 has a through hole 24 corresponding to the through hole 13, and the introduction portion 233 of the abutting member 23 extends into the through hole 24, and the two introduction portions 233 are arranged opposite to each other, so that the soldering piece 32 can be inserted between the abutting portions 232 from the introduction portion 233, and can also be inserted between the abutting portions 232 from the arc-shaped connecting portion 231. At the same time, due to the existence of the two abutting portions 232, the plug spring 20 and the soldering piece 32 are fixed, and the use of solder for welding can be avoided. Therefore, even if the length of the soldering piece 32 is the shortest, as long as it can be inserted into the plug spring 20 and can be fixed by the abutting portions 232, it is sufficient. It is also because no soldering is required that the length of the soldering piece 32 can be designed to be the shortest, which is undoubtedly conducive to reducing the volume of the entire speaker. Of course, it is undoubtedly easier to complete the plug-in fixation for a longer soldering piece 32, thereby achieving compatibility with sub-speakers having soldering pieces 32 of different lengths.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
