Description

Technical Field

[0001] The present invention relates to the technical field of electroacoustic conversion, and in particular to a sound module and an application device. Background Art

[0002] As a commonly used sound-generating device, the sound module is widely used in application devices with sound generation requirements. The sound module is usually fixed by installing the sound unit in a bracket or a casing, and then connecting the casing with an external structural member.

[0003] At present, when the sound unit in the sound module is connected to the bracket, corresponding mounting parts are usually provided on the basin frame of the sound unit and the bracket respectively, and the installation of the sound unit and the bracket is achieved through the cooperation of the corresponding mounting parts. However, since the sound unit needs to be connected to the cable, and the length of the cable is limited, and sound units with different structural designs usually have different installation posture requirements, the existing mounting parts are usually one-to-one designs, so that the sound unit can only be connected to the bracket at a specified angle while satisfying the length of the cable and the installation posture of the sound unit. This results in that among the multiple sound units with different structural designs, each sound unit needs to redesign the structure of the basin frame and the bracket according to its structure, which not only leads to long research and development time, but also leads to low design efficiency. Summary of the invention

[0004] The main purpose of the present invention is to propose a sound module and an application device, aiming to solve the problem in the prior art that each sound unit with different structures needs to redesign the basin frame and bracket, resulting in increased R&D costs, production costs and R&D time, and low design efficiency.

[0010] In one embodiment, the two sides of the bracket are respectively a first side and a second side, the first side is recessed toward the second side to form a limiting groove, the notch of the limiting groove faces away from the second side, and the bottom wall of the limiting groove arranged opposite to the notch forms a mounting hole, the mounting hole is arranged corresponding to the diaphragm assembly of the sound unit, and a plurality of positioning columns are arranged at intervals on the bottom wall around the mounting hole, each of the positioning columns can be aligned and plugged with any of the positioning holes, and a plurality of buckles are arranged at intervals on the side walls of the limiting groove along its circumference.

[0011] In one embodiment, the limiting groove is a circular groove, and the shape of the basin frame is adapted to the shape of the limiting groove.

[0012] In one embodiment, the outer periphery of the basin frame has a mounting edge, and the mounting edge is provided with a plurality of positioning holes at intervals along its circumference, and a plurality of the buckles are located at the notch to form a limiting space with the bottom wall of the groove;

[0013] The sound-emitting unit can rotate relative to the bracket when the mounting edge extends toward the limiting space, so as to drive the mounting edge to rotate so that each positioning column can be aligned with any positioning hole, and the positioning column is plugged into the positioning hole aligned with it after the mounting edge extends into the limiting space; a plurality of buckles are engaged with the mounting edge after the mounting edge extends into the limiting space, so as to limit the mounting edge within the limiting space.

[0014] In one embodiment, the outer edge of the mounting edge is bent in a direction away from the second side to form a folded edge, and a side edge of the folded edge away from the mounting edge is used to press against the buckle after the mounting edge extends into the limiting space.

[0015] In one embodiment, the folded edge is smoothly connected to the outer edge of the mounting edge to form an arc-shaped chamfer, and the arc-shaped chamfer is used to abut against the buckle when the mounting edge extends into the limiting space. The shape of the folded edge matches the shape of the groove side wall of the limiting groove, and the folded edge is used to slide in contact with the groove side wall of the limiting groove when the mounting edge extends into the limiting space.

[0016] In one embodiment, each of the clips extends from the groove side wall of the limiting groove toward the mounting hole, and a side of each of the clips away from the second side is a guide surface, and the guide surface is inclined toward the second side along the extension direction of the clip to form a guide slope, and the guide slope is used to abut against the arc chamfer when the mounting edge extends into the limiting space.

[0017] In one embodiment, a surface of each of the buckles facing the second side is a contact surface, which is arranged parallel to the second side and is used to contact an edge of the folded edge away from the installation edge after the installation edge extends into the limiting space.

[0020] In one embodiment, each of the positioning columns includes a connecting column and a guide head, the connecting column is a cylinder, and each of the positioning holes is a circular hole. One end of the connecting column is connected to the bottom wall of the limiting groove, and the other end is connected to the guide head. The guide head protrudes in a direction away from the connecting column to form an arc-shaped guide surface.

[0021] In one embodiment, a protrusion is formed on the second side of the bracket toward a side away from the limiting groove, and the shape of the protrusion is adapted to the shape of the limiting groove and is arranged corresponding to the limiting groove.

The sounding unit is limited so that it cannot rotate by plugging in the positioning hole and the positioning column, and then the sounding unit is limited so that the positioning hole and the positioning column will not be separated by the buckle and the basin frame, thereby completing the installation between the sounding unit and the cable. When in use, the sounding unit can be rotated to correspond to different mounting holes and mounting columns according to the cable connection position of different sounding unit structures to meet the length requirement and installation posture requirement of the cable, so that the sounding unit of any structure does not need to redesign the bracket and basin frame. The present invention arranges a plurality of positioning holes on the basin frame, arranges a plurality of positioning columns on the bracket, and rotates the sound units so that the sound units with different structural designs can meet the length requirements and installation posture requirements of the cable. There is no need to redesign the basin frame and the bracket for sound units with different structural designs, which greatly reduces the R&D cost and time, and allows multiple sound units to share a set of molds, saving the costs of multiple sets of basin frame molds, parts management, tooling, production line matching costs, etc., thereby improving the design efficiency.

[0038] When the sound unit is connected to the bracket in the prior art, corresponding mounting parts are usually provided on the basin frame of the sound unit and the bracket respectively, and the installation of the sound unit and the bracket is achieved through the cooperation of the corresponding mounting parts. However, since the sound unit needs to be connected to the cable, the length of the cable is limited, and sound units with different structural designs usually have different installation posture requirements, the mounting parts in the prior art are usually one-to-one designs, so that the sound unit can only be connected to the bracket at a specified angle while meeting the cable length and the installation posture of the sound unit. This results in that each sound unit with a different structural design needs to redesign the structure of the basin frame and the bracket according to its structure, which not only leads to an increase in R&D costs and time, but also leads to low design efficiency.

[0039] In order to solve the above problems, the present invention proposes a sound module 100 .

[0040] Please combine Figure 1 , Figure 2 and Figure 6 The sound module 100100 of this embodiment includes a bracket 1 and a sound unit 2, and the bracket 1 is provided with a buckle 16 and a positioning column 15; the sound unit 2 has a basin frame 21, the basin frame 21 is separately provided with the bracket 1, and the basin frame 21 is provided with a plurality of positioning holes 23 at intervals along its circumference; the sound unit 2 can rotate relative to the bracket 1 so that the positioning column 15 can be aligned with and plugged into any positioning hole 23, and the buckle 16 is used to clamp with the basin frame 21 to fix the sound unit 2 to the bracket 1.

[0041] It should be noted that the sound-generating monomer 2 generally refers to a monomer structure having a vibration system, a magnetic circuit system, and a basin frame 21, which drives the diaphragm 26 to vibrate and produce sound by electromagnetic induction through a magnet and a coil. In this embodiment, the sound-generating monomer 2 is used as a speaker monomer for explanation. It can be understood that the size of the mounting hole 14 should be greater than or equal to the size of the diaphragm 26 of the sound-generating monomer 2, so that the diaphragm 26 of the sound-generating monomer 2 is exposed to avoid affecting the sound performance of the sound-generating monomer 2 itself. When the positioning hole 23 on the basin frame 21 of the sound-generating monomer 2 is plugged with different positioning columns 15, the rotation angle of the sound-generating monomer 2 relative to the bracket 1 is also different, thereby adjusting the distance between the wiring harness connection position of the sound-generating monomer 2 and the wiring harness bracket 1, so that the length of the wiring harness can be shortened as much as possible, realizing the optimization of the space layout in the application device, and reducing the overall volume of the sound module 100.

[0042] The technical solution of the present invention is to set the basin frame 21 separately, set the buckle 16 and the positioning column 15 on the bracket 1, and set a plurality of mounting holes 14 on the basin frame 21 of the sound unit 2. During installation, according to the specific structure of the sound unit 2, it is determined to what position the sound unit 2 needs to be rotated to meet the length requirement of the cable, and after the sound unit 2 is rotated to the corresponding position relative to the bracket 1, the positioning hole 23 on the basin frame 21 is aligned with the positioning column 15 on the bracket 1, and the sound unit 2 is pressed toward the bracket 1 so that the positioning hole 23 is plugged into the positioning column 15. The sounding unit 2 is limited by the plugging of the positioning hole 23 and the positioning column 15 so that it cannot rotate, and then the sounding unit 2 is limited by the clamping of the buckle 16 and the basin frame 21 so that the positioning hole 23 and the positioning column 15 will not be separated, thereby completing the installation between the sounding unit 2 and the sounding unit 2. When in use, the sounding unit 2 can be rotated to correspond to different mounting holes 14 and mounting columns according to the cable connection position of different sounding unit 2 structures to meet the length requirements and installation posture requirements of the cable, so that the sounding unit 2 of any structure does not need to be redesigned. The present invention sets a plurality of positioning holes 23 on the basin frame 21 and a plurality of positioning columns 15 on the bracket 1, and rotates the sounding unit 2 so that the sounding units 2 of different structural designs can meet the length requirements and installation posture requirements of the cable, so that there is no need to redesign the basin frame 21 and the bracket 1 for the sounding units 2 of different structural designs, which greatly reduces the R&D cost and R&D time, so that multiple sounding units can share a set of molds, saving the cost of multiple sets of basin frame molds, parts management, tooling, production line matching costs, etc., and improving the design efficiency.

[0043] In one embodiment, there are multiple positioning posts 15 , and the spacing between the multiple positioning posts 15 is uniform, and the spacing between the multiple positioning holes 23 is uniform.

[0044] When the intervals between multiple positioning holes 23 are uniform and the intervals between multiple positioning columns 15 are uniform, after the sound unit 2 is rotated until one positioning hole 23 is aligned with one positioning column 15, all other positioning holes 23 and positioning columns 15 can be aligned, thereby simplifying the alignment process between the sound unit 2 and the bracket 1 and improving assembly efficiency.

[0045] Furthermore, the number of positioning holes 23 is A, the number of positioning columns 15 is B, A=nB, wherein n is a positive integer, and the number of positioning holes 23 is at least equal to the number of positioning columns 15, so that the sound unit can be fully plugged into the bracket. At the same time, when the number A of the positioning holes 23 is a positive integer multiple of the number B of the positioning columns 15, the sound unit 2 can be plugged into all the positioning columns 15 by simply rotating 360 / A°, thereby improving the adjustable angle range of the sound unit 2 and improving the adaptability of the bracket 1 to the sound units 2 with different structural designs.

[0046] Specifically, the value range of n is 3 to 6. It is understandable that when the value of n is too small, the minimum rotatable angle of the sound unit 2 will be limited, and it will not be able to perfectly adapt to the rotation angle required by various sound unit 2 structural designs. When the value range of n is too large, it will lead to too many unnecessary mounting holes 14 and increase the time and cost required for processing the basin frame 21. Therefore, when the value range of n is 3 to 6, it can provide enough rotatable angles to meet the needs of sound units 2 with different structural designs, and can also reduce the cost and time of processing the basin frame 21.

[0047] In one embodiment, the two sides of the bracket 1 are respectively a first side 11 and a second side 12, the first side 11 is recessed toward the second side 12 to form a limiting groove 13, the notch 131 of the limiting groove 13 is away from the second side 12, and the bottom wall 132 of the limiting groove 13 which is arranged opposite to the notch 131 forms a mounting hole 14, the mounting hole 14 is arranged corresponding to the diaphragm 26 assembly of the sound unit 2, the bottom wall 132 is provided with a plurality of positioning columns 15 at intervals around the mounting hole 14, each positioning column 15 can be aligned and plugged with any positioning hole 23, and the side wall 133 of the limiting groove 13 is provided with a plurality of buckles 16 at intervals along its circumference.

[0048] The positioning column 15 is arranged on the bottom wall 132 of the limiting groove 13, and the buckle 16 is arranged on the side wall 133 of the limiting groove 13, so that a limiting space 17 for limiting the sound unit 2 can be enclosed between the bottom wall 132 and the buckle 16. On the one hand, the limiting groove 13 can be used to guide the sound unit 2 through the abutment between the groove side wall 133 and the outer wall of the sound unit 2, so as to facilitate the alignment of the positioning hole 23 on the sound unit 2 and the positioning column 15 on the limiting groove 13. On the other hand, the abutment between the side groove wall of the limiting groove 13 and the outer wall of the sound unit 2 can further limit the sound unit 2 to avoid the sound unit 2 from shifting along its radial direction. The buckle 16 and the basin frame 21 are clamped to limit the sound unit 2 so that it cannot leave the limiting space 17, thereby completing the installation between the sound unit 2 and the bracket 1.

[0049] In one embodiment, the limiting groove 13 is a circular groove, and the shape of the basin frame 21 matches the shape of the limiting groove 13 .

[0050] It can be understood that the limiting groove 13 can be a regular polygonal groove, the shape of the basin frame 21 is adapted to the shape of the limiting groove 13, and the number of positioning holes 23 is the same as the number of sides of the regular polygon, which can also meet the design of adjusting the angle of the sound unit 2 by rotating relative to the bracket 1. However, the regular polygonal structure requires all sides to be aligned during alignment in order to achieve plug-in, which increases the difficulty of assembly. When the limiting groove 13 is a circular groove, no matter how the sound unit 2 is rotated, the basin frame 21 and the limiting groove 13 are always aligned everywhere, thereby reducing the difficulty of assembly and improving assembly efficiency.

[0051] In one embodiment, the outer periphery of the basin frame 21 has a mounting edge 22, and the mounting edge 22 is provided with a plurality of positioning holes 23 at intervals along its circumference, and a plurality of buckles 16 are located at the slot 131 to form a limiting space 17 between the slot bottom wall 132; the sound unit 2 can rotate relative to the bracket 1 when the mounting edge 22 extends toward the limiting space 17, so as to drive the mounting edge 22 to rotate so that each positioning column 15 can be aligned with any positioning hole 23, and the positioning column 15 is plugged into the positioning hole 23 aligned with the mounting edge 22 after the mounting edge 22 extends into the limiting space 17; a plurality of buckles 16 are engaged with the mounting edge 22 after the mounting edge 22 extends into the limiting space 17, so as to limit the mounting edge 22 within the limiting space 17.

[0052] The positioning hole 23 is arranged on the mounting edge 22, and the size of the mounting edge 22 is adapted to the size of the limiting groove 13, so that the mounting edge 22 can be formed by extending and extending at the end of the basin frame 21, and there is no need to set the basin frame 21 as a whole to the size of the limiting groove 13, thereby saving materials and reducing the volume of the sound unit 2. By plugging the mounting edge 22 with the positioning hole 23 and abutting with the buckle 16, the size of the mounting edge 22 can be adjusted according to the size of the limiting space 17, thereby adapting to any size of the limiting space 17 and improving applicability.

[0053] Please combine Figure 2 and Figure 3 In one embodiment, the outer edge of the mounting edge 22 is bent in a direction away from the second side 12 to form a folded edge 24, and the side edge of the folded edge 24 away from the mounting edge 22 is used to press against the buckle 16 after the mounting edge 22 extends into the limiting space 17. It can be understood that in order to reduce the volume and weight of the sound unit 2, the thickness of the mounting edge 22 is less than the thickness of the limiting space 17. If the mounting edge 22 cannot press against both the groove bottom wall 132 of the limiting groove 13 and the buckle 16, the sound unit 2 will be tilted, offset or even fall off. Therefore, the outer edge of the mounting edge 22 is bent in a direction away from the second side 12 to form a folded edge 24, which increases the thickness of the mounting edge 22 without excessively increasing the volume and weight of the sound unit 2, so that the folded edge 24 presses against both the groove bottom wall 132 of the limiting groove 13 and the buckle 16, respectively, to ensure the stability of the installation of the sound unit 2.

[0054] Furthermore, the folded edge 24 is smoothly connected to the outer edge of the mounting edge 22 to form an arc chamfer 25, and the arc chamfer 25 is used to abut against the buckle 16 when the mounting edge 22 extends into the limiting space 17. The shape of the folded edge 24 matches the shape of the groove side wall 133 of the limiting groove 13, and the folded edge 24 is used to slide and contact with the groove side wall 133 of the limiting groove 13 when the mounting edge 22 extends into the limiting space 17.

[0055] The shape of the folded edge 24 is adapted to the shape of the limiting groove 13, and the folded edge 24 can slide and contact with the groove side wall 133, so that the folded edge 24 abuts against the groove side wall 133 of the limiting groove 13 after extending into the limiting space 17, thereby limiting the basin frame 21, and can prevent the basin frame 21 from producing lateral displacement or radial tilt due to external force during use, thereby improving the stability of the connection between the sound unit 2 and the bracket 1, and the arc chamfer 25 reduces the sharp part of the folded edge 24, and the buckle 16 can smoothly contact with the surface of the arc chamfer 25, reducing the assembly resistance, and making it easier for the basin frame 21 to slide into place when it extends into the limiting groove 13.

[0056] Please combine Figure 3 , Figure 6 and Figure 7In one embodiment, each buckle 16 extends from the groove side wall 133 of the limiting groove 13 to the mounting hole 23, and a side of each buckle 16 away from the second side 12 is a guide surface 161, and the guide surface 161 is inclined toward the second side 12 along the extension direction of the buckle 16 to form a guide slope, and the guide slope is used to abut against the arc chamfer 25 when the mounting edge 22 extends into the limiting space 17.

[0057] The contact between the guide slope and the arc chamfer 25 forms a smooth guiding transition area. During the assembly process, the guide slope guides the basin frame 21 to be gradually pressed into place, reducing the assembly resistance. The user does not need to apply excessive force to complete the assembly, thereby improving the assembly efficiency. At the same time, the sliding contact between the guide slope and the arc chamfer 25 effectively disperses the impact force during assembly, avoiding wear or damage to the edge of the buckle 16 or the basin frame 21 due to excessive direct force, thereby improving the product yield of the sound module 100.

[0058] See also Figure 7 In one embodiment, a side of each buckle 16 facing the second side 12 is a contact surface 162, which is arranged parallel to the second side 12 and is used to press against an edge of the folded edge 24 away from the installation edge 22 after the installation edge 22 extends into the limiting space 17.

[0059] The abutment surface 162 is arranged parallel to the second side 12, and the abutment surface 162 abuts against the mounting edge 22, and the folded edge 24 is perpendicular to the mounting edge 22, so that the abutment surface 162 is flush with the end of the folded edge 24 away from the mounting edge 22, so that the mounting edge 22 and the abutment surface 162 are evenly stressed at all locations when they abut, thereby preventing the basin frame 21 from shifting or tilting due to uneven force, and improving the accuracy of the bracket 1 in limiting the sound unit 2.

[0060] Further, the two sides of the guide surface 161 along the extension direction of the groove side wall 133 of the limiting groove 13 are connected to the two sides of the abutting surface 162 along the extension direction of the groove side wall 133 of the limiting groove 13 through two transition surfaces 163, and the spacing between the two transition surfaces 163 is gradually expanded from the guide surface 161 to the abutting surface 162. The spacing between the two transition surfaces 163 is gradually expanded from the guide surface 161 to the abutting surface 162, that is, the size of the abutting surface 162 is larger than the size of the guide surface 161. The larger size of the abutting surface 162 can increase its contact area with the mounting edge 22, thereby dispersing the force per unit area, reducing the pressure of the abutting surface 162, reducing local stress concentration, and improving the anti-deformation ability of the buckle 16, and the inclined design of the transition surface 163 can optimize the overall force distribution of the buckle 16 and improve the strength and stability of the buckle 16.

[0061] In one embodiment, the guide slope extends from the edge of the notch 131 of the limiting groove 13 to the mounting hole 23. The extension of the guide slope from the edge of the notch 131 of the limiting groove 13 to the mounting hole 23 means that when the mounting edge 22 just extends into the limiting groove 13 and contacts the buckle 16, it can be guided by the guide slope, so that the basin frame 21 will not deviate during the pressing process, which reduces the difficulty of assembly and improves the assembly efficiency.

[0062] Please combine Figure 2 and Figures 3 to 6 In one embodiment, the limiting groove 13 is a circular groove, and the shape of the basin frame 21 is adapted to the shape of the limiting groove 13. It can be understood that the limiting groove 13 can be a regular polygonal groove, the shape of the basin frame 21 is adapted to the shape of the limiting groove 13, and the number of positioning holes 23 is the same as the number of sides of the regular polygon, which can also meet the design of adjusting the angle of the sound unit 2 by rotating relative to the bracket 1. However, the regular polygon structure needs to align all sides to achieve plug-in during alignment, which increases the difficulty of assembly. When the limiting groove 13 is a circular groove, no matter how the sound unit 2 is rotated, the basin frame 21 and the limiting groove 13 are always aligned everywhere, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0063] See also Figure 6 In one embodiment, each positioning column 15 includes a connecting column 151 and a guide head 152. The connecting column 151 is a cylinder, and each positioning hole 23 is a circular hole. One end of the connecting column 151 is connected to the groove bottom wall 132 of the limiting groove 13, and the other end is connected to the guide head 152. The guide head 152 protrudes in the direction away from the connecting column 151 to form an arc-shaped guide surface. The connecting column 151 is a cylinder, and the positioning hole 23 is a circular hole, so that the connecting column 151 and the connecting hole can still be plugged in and matched after the sound unit 2 rotates to any angle, which improves the convenience and efficiency of assembly. At the same time, the arc-shaped guide surface of the guide head 152 can play a guiding and aligning role when the positioning hole 23 and the positioning column 15 are just plugged in. There is no need to fully align the positioning column 15 with the positioning hole 23, and the plugging can be completed under the guidance of the guide head 152, which reduces the difficulty of assembly and improves the assembly efficiency.

[0064] Please combine Figure 1 and Figure 5 In one embodiment, a protrusion 18 is formed on the second side 12 of the bracket 1 on the side facing away from the limiting groove 13. The shape of the protrusion 18 matches the shape of the limiting groove 13 and is arranged corresponding to the limiting groove 13. It can be understood that after the limiting groove 13 is formed on the bracket 1, the groove bottom wall 132 of the limiting groove 13 is relatively weak and has a weak pressure bearing capacity, and is easily damaged after being subjected to external force. Therefore, the protrusion 18 is arranged corresponding to the limiting groove 13 to reinforce the groove bottom wall 132 of the limiting groove 13, thereby improving the overall strength and stability of the bracket 1.
