Loudspeaker and earphone

Abstract

The application discloses a loudspeaker and earphone, and belongs to the technical field of electronic equipment. The loudspeaker comprises a voice coil, a first lead-out wire and a first supporting piece. The first lead-out wire is connected with the voice coil and supported on the first supporting piece. The first lead-out wire forms a first overhanging part between the first supporting piece and the voice coil. The first overhanging part comprises a first arc-shaped transition section. The first arc-shaped transition section is arc-shapedly bent towards one side of the first edge away from the second edge. The length of the first arc-shaped transition section is not less than one third of the total length of the first overhanging part. The loudspeaker provided by the application is characterized in that the first arc-shaped transition section is arc-shapedly bent towards one side of the first edge away from the second edge, and the length of the first arc-shaped transition section is not less than one third of the total length of the first overhanging part. As a result, the first overhanging part has a longer outwardly protruding curved section, and the first overhanging part can be far away from the first edge, thereby reducing the possibility that the first lead-out wire and the voice coil interfere with each other and generate noise.

Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a speaker and headphones. Background Technology

[0002] A loudspeaker converts audio electrical signals into sound waves. A loudspeaker may include a magnetic circuit assembly, a diaphragm, a voice coil, and lead wires. The voice coil is positioned within the magnetic field of the magnetic circuit assembly and is connected to the diaphragm. The lead wires are connected to the voice coil. When an audio electrical signal is input to the voice coil through the lead wires, the energized voice coil, situated in the magnetic field, drives the diaphragm to vibrate under the influence of electromagnetic force. The vibration of the diaphragm pushes surrounding air molecules to form sound waves with varying density, thus producing sound. In related technologies, the lead wires are prone to interference with the voice coil, generating noise. Utility Model Content

[0003] This application provides a speaker and headphones that can solve the technical problem that the lead wires easily interfere with the voice coil, resulting in noise.

[0004] To address the aforementioned technical problems, this application provides a loudspeaker comprising a voice coil, a first lead wire, and a first support member. On a first reference plane perpendicular to the vibration direction of the loudspeaker, the voice coil has a first direction and a second direction orthogonal to each other. The voice coil includes a first side, a second side, a third side, and a fourth side. The first and second sides are arranged along the first direction and spaced apart from each other along the second direction. The third and fourth sides are spaced apart from each other along the first direction and respectively connect to the first and second sides. The first support member is located on the side of the first side away from the second side. The first lead wire connects to the voice coil and is supported by the first support member. The first lead wire forms a first suspended portion between the first support member and the voice coil. The first suspended portion includes a first arc-shaped transition section. Viewed along the vibration direction, the first arc-shaped transition section curves in an arc towards the side of the first side away from the second side, and the length of the first arc-shaped transition section is not less than one-third of the total length of the first suspended portion.

[0005] This application also provides an earphone, which includes a speaker as described above.

[0006] The loudspeaker provided in this application has a first arc-shaped transition section that bends in an arc towards the side away from the second side, and the length of the first arc-shaped transition section is not less than one-third of the total length of the first suspended part. This allows the first suspended part to have a longer outwardly protruding curved section, and the first suspended part can be far away from the first side, thereby reducing the possibility of interference between the first lead wire and the voice coil, which would generate noise.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This application provides a loudspeaker. Please refer to [link / reference]. Figure 1 , Figure 2 The loudspeaker 100 may include a magnetic circuit assembly 20, a voice coil assembly 30, and a frame assembly 40. The magnetic circuit assembly 20 and the voice coil assembly 30 are both mounted on the frame assembly 40.

[0020] The magnetic circuit assembly 20 is used to generate a magnetic field. Exemplarily, the magnetic circuit assembly 20 includes a magnet, such as ferrite or neodymium iron boron.

[0021] Please see Figure 2 , Figure 3The voice coil assembly 30 includes a diaphragm 31, a voice coil 32, and a first lead 33. The voice coil 32 is disposed in the magnetic field generated by the magnetic circuit assembly 20 and connected to the diaphragm 31. Upon receiving an audio electrical signal, the voice coil 32 can drive the diaphragm 31 to vibrate within the magnetic field. One end of the first lead 33 is connected to the voice coil 32, and the other end is connected to the circuit board (not shown) of the speaker 100. The first lead 33 is used to input an audio electrical signal to the voice coil 32. When an audio electrical signal is input to the voice coil 32 through the first lead 33, the energized voice coil 32, located in the magnetic field, drives the diaphragm 31 to vibrate under the action of electromagnetic force. The vibration of the diaphragm 31 pushes the surrounding air molecules to form sound waves with varying density, thus producing sound.

[0022] Please see Figure 2 , Figure 3 The basket frame assembly 40 may include a basket frame 43 and a first support member 41. The basket frame 43 can be used to support the magnetic circuit assembly 20 and the voice coil assembly 30. The first support member 41 is used to support the first lead wire 33. The first support member 41 may protrude from the side of the basket frame 43 near the voice coil 32, or it may be part of the basket frame 43; this application does not limit this.

[0023] Please see Figures 2-4 On a first reference plane perpendicular to the vibration direction of the loudspeaker 100, the voice coil 32 has a first direction and a second direction orthogonal to each other. Due to limitations in the manufacturing process, the parallelism or perpendicularity in this application may have a deviation of ±5°. Exemplarily, the vibration direction may be... Figure 2 The Z-axis direction in the diagram, the first direction can be... Figure 4 The X-axis direction, the second direction can be Figure 4 The Y-axis direction is specified. The voice coil 32 includes a first side 321, a second side 322, a third side 323, and a fourth side 324. The first side 321 and the second side 322 are arranged along a first direction and spaced apart from each other along a second direction. The third side 323 and the fourth side 324 are spaced apart from each other along the first direction and respectively connect the first side 321 and the second side 322. The first side 321 and the second side 322 can be parallel to a reference line along the first direction, or they can be curved relative to the reference line along the first direction. The transition between two adjacent sides of the voice coil 32 can be an arc.

[0024] Please see Figure 3 , Figure 4The first support member 41 is located on the side of the first side 321 opposite to the second side 322, and the first lead wire 33 is supported on the first support member 41. The first lead wire 33 forms a first suspended portion 331 between the first support member 41 and the voice coil 32. The first suspended portion 331 has a certain distance from other components so that the first lead wire 33 is not likely to interfere with other components during the movement of the voice coil 32.

[0025] Please see Figure 4 The first suspended portion 331 includes a first arc-shaped transition segment 3311. Viewed along the vibration direction, the first arc-shaped transition segment 3311 curves in an arc towards the side of the first side 321 away from the second side 322, and the length of the first arc-shaped transition segment 3311 is not less than one-third of the total length of the first suspended portion 331. Here, "arc-shaped" refers to a line segment whose curvature is not zero; correspondingly, the length of the first arc-shaped transition segment 3311 refers to the length of a continuous line segment on the first suspended portion 331 where the curvature at each point is not zero. The arc-shaped curve of the first arc-shaped transition segment 3311 towards the side of the first side 321 away from the second side 322 means that, viewed along a second direction from the second side 322 to the first side 321, the first arc-shaped transition segment 3311 exhibits an outwardly protruding curved shape.

[0026] The loudspeaker 100 provided in this application is provided with a first arc-shaped transition section 3311 that bends in an arc towards the side of the first side 321 away from the second side 322, and the length of the first arc-shaped transition section 3311 is not less than one-third of the total length of the first suspended portion 331, so that the first suspended portion 331 has a longer outwardly protruding curved section, and the first suspended portion 331 can be far away from the first side 321, thereby reducing the possibility of interference between the first lead wire 33 and the voice coil 32 and the generation of noise.

[0027] In some embodiments, the ratio of the length of the first arc-shaped transition segment 3311 to the total length of the first suspended portion 331 can be 1 / 3, 1 / 2, 2 / 3, 4 / 5 or 1, and no specific limitation is made here.

[0028] In some embodiments, such as Figure 1 , Figure 2 As shown, the loudspeaker 100 may also include a housing assembly 10, a magnetic circuit assembly 20, a voice coil assembly 30, and a frame assembly 40, all of which are installed inside the housing assembly 10. An acoustic cavity 11 is formed between the housing assembly 10 and the diaphragm 31, and the housing assembly 10 is provided with a sound outlet 12 communicating with the acoustic cavity 11, through which sound can be output.

[0029] Please see Figure 4In some embodiments, one end of the first arc-shaped transition segment 3311 is connected to the voice coil 32, and the curvature of at least a portion of the first arc-shaped transition segment 3311 near the connection point with the voice coil 32 is greater than the curvature of other segments away from the connection point. This configuration has two advantages: firstly, the curvature of at least a portion of the first arc-shaped transition segment 3311 near the connection point with the voice coil 32 is relatively large, causing the connection segment of the first arc-shaped transition segment 3311 to move away from the voice coil 32 rapidly at a large slope, which helps reduce the possibility of interference between the first lead 33 and the voice coil 32, resulting in noise; secondly, the curvature of other segments of the first arc-shaped transition segment 3311 away from the connection point with the voice coil 32 is relatively small, preventing the distance between the first arc-shaped transition segment 3311 and the first side 321 from being too large, which helps reduce the size of the speaker 100.

[0030] In some embodiments, such as Figure 4 As shown, one end of the first arc-shaped transition section 3311 is connected to the voice coil 32, and the other end is supported by the first support member 41. At this time, the ratio of the length of the first arc-shaped transition section 3311 to the total length of the first suspended portion 331 is close to 1, meaning that the first suspended portion 331 is curved in an arc towards the side of the first side 321 away from the second side 322. With this configuration, the first suspended portion 331 has the largest outwardly protruding curved section, allowing it to move away from the first side 321, thereby reducing the possibility of interference between the first lead 33 and the voice coil 32, which could generate noise.

[0031] In some embodiments, such as Figure 5 , Figure 6 As shown, the first suspended portion 331 also includes a first bent connecting segment 512. The first bent connecting segment 512 connects the first arc-shaped transition segment 3311 and the voice coil 32, and is bent towards the voice coil 32 relative to the first arc-shaped transition segment 3311. The length of the first bent connecting segment 512 is less than the length of the first arc-shaped transition segment 3311. The first bent connecting segment 512 can be a straight line or a curve. When the first bent connecting segment 512 is a straight line, there is an angle between the lines connecting the two ends of the first bent connecting segment 512 and the first arc-shaped transition segment 3311, such as... Figure 5 As shown; when the first bent connecting segment 512 is a curve, the bending direction of the first bent connecting segment 512 can be different from the bending direction of the first arc-shaped transition segment 3311, such as... Figure 6As shown. The first arc-shaped transition section 3311 is indirectly connected to the voice coil 32 through a short first bent connecting section 512, and the first bent connecting section 512 bends towards the voice coil 32, so that the first bent connecting section 512 is spaced between the first arc-shaped transition section 3311 and the voice coil 32. The first arc-shaped transition section 3311 can be further away from the voice coil 32, thereby reducing the possibility of interference between the first lead 33 and the voice coil 32 and the generation of noise.

[0032] Please see Figure 5 In some embodiments, the extension component of the first bent connecting segment 512 along the first direction is smaller than the extension component of the first arc-shaped transition segment 3311 along the first direction, and the extension component of the first bent connecting segment 512 along the second direction is larger than the extension component of the first arc-shaped transition segment 3311 along the second direction. This configuration has two advantages: firstly, the larger extension component of the first bent connecting segment 512 along the second direction allows the first arc-shaped transition segment 3311 to move rapidly away from the voice coil 32 at a larger slope, thereby reducing the possibility of interference between the first lead 33 and the voice coil 32, resulting in noise; secondly, the larger extension component of the first arc-shaped transition segment 3311 along the first direction allows full utilization of the first direction dimension of the voice coil 32 to increase the size of the first suspended portion 331, thereby reducing the bending stiffness of the first suspended portion 331. This allows the first suspended portion 331 to move synchronously with the voice coil 32, which helps reduce interference between the first lead 33 and the voice coil 32 due to asynchronous movement, thus reducing the possibility of noise generation.

[0033] like Figure 5 As shown, in some embodiments, the projection of the first arcuate transition segment 3311 along the second direction may fall between the third side 323 and the fourth side 324. Taking the end of the first bent connecting segment 512 near the voice coil 32 as a reference point, the first bent connecting segment 512 has an extension component along the first direction toward the first support member 41 and an extension component along the second direction toward the side of the first side 321 away from the second side 322. The line connecting the two ends of the first arcuate transition segment 3311 has a first angle α1 with the first direction, and the line connecting the two ends of the first bent connecting segment 512 has a second angle α2 with the first direction, the second angle α2 being greater than the first angle α1. With this configuration, on the one hand, the angle formed by the line connecting the two ends of the first bent connecting section 512 and the first direction is relatively large, so that the first suspended part 331 moves away from the voice coil 32 at a large slope, which helps to reduce the possibility of interference between the first lead-out line 33 and the voice coil 32 and the noise generated; on the other hand, the angle formed by the line connecting the two ends of the first arc transition section 3311 and the first direction is relatively small, so that the distance between the first arc transition section 3311 and the first side 321 is not too large, which helps to reduce the size of the speaker 100.

[0034] Please see Figure 6 In some embodiments, the projection of the first arc-shaped transition segment 3311 along the second direction can partially fall outside the third side 323 and the fourth side 324. Taking the end of the first bent connecting segment 512 near the voice coil 32 as a reference point, the first bent connecting segment 512 has an extension component along the first direction away from the first support member 41 and an extension component along the second direction toward the first side 321 away from the second side 322. Setting the first bent connecting segment 512 to have an extension component along the second direction toward the first side 321 away from the second side 322, so that the projection of the first arc-shaped transition segment 3311 along the second direction can partially fall outside the third side 323 and the fourth side 324, can further increase the size of the first suspended portion 331, thereby reducing the bending stiffness of the first suspended portion 331, so that the first suspended portion 331 can move synchronously with the voice coil 32, which helps to reduce interference between the first lead wire 33 and the voice coil 32 due to asynchronous movement, thereby reducing the possibility of generating noise.

[0035] In some embodiments, such as Figure 6 As shown, the line connecting the two ends of the first arc-shaped transition section 3311 forms a first angle α1 with the first direction, and the line connecting the two ends of the first bent connecting section 512 forms a second angle α2 with the first direction, the second angle α2 being greater than the first angle α1. This arrangement has two advantages: firstly, the angle between the line connecting the two ends of the first bent connecting section 512 and the first direction is relatively large, causing the first suspended portion 331 to move away from the voice coil 32 quickly at a large slope, which helps reduce the possibility of interference between the first lead-out line 33 and the voice coil 32, resulting in noise; secondly, the angle between the line connecting the two ends of the first arc-shaped transition section 3311 and the first direction is relatively small, preventing the distance between the first arc-shaped transition section 3311 and the first side 321 from being too large, which helps reduce the size of the speaker 100.

[0036] In some embodiments, the first bent connecting segment 512 may be connected to the first side 321. Alternatively, see [link to relevant documentation]. Figure 6In some embodiments, the first bent connecting segment 512 is located on the side of the third side 323 away from the fourth side 324, and the first bent connecting segment 512 is curved toward the side of the first side 321 toward the second side 322. That is, the first bent connecting segment 512 can be connected to the connection part between the first side 321 and the third side 323. With this configuration, on the one hand, the first bent connecting section 512 is located on the side of the third side 323 away from the fourth side 324. This allows for full utilization of the dimension of the voice coil 32 in the first direction to increase the dimension of the first suspended portion 331, thereby reducing the bending stiffness of the first suspended portion 331. This enables the first suspended portion 331 to move synchronously with the voice coil 32, which helps reduce interference between the first lead wire 33 and the voice coil 32 due to asynchronous movement, thus reducing the possibility of generating noise. On the other hand, the first bent connecting section 512 bends in an arc towards the side of the first side 321 toward the second side 322, which increases the distance between the first arc transition section 3311 and the first bent connecting section 512 in the second direction, thereby reducing the possibility of interference between the first arc transition section 3311 and the first bent connecting section 512, resulting in noise.

[0037] In some embodiments, the dimension of the voice coil 32 in the first direction is equal to the dimension in the second direction. The voice coil 32 may be generally cubic in shape.

[0038] In some embodiments, such as Figure 5 As shown, the voice coil 32 has a larger dimension in the first direction than in the second direction. The voice coil 32 can be approximately cuboid in shape, having two long sides and two short sides. The connection point between the first suspended portion 331 and the voice coil 32 is located near the third side 323, and the first support member 41 is located near the fourth side 324. The length of the first suspended portion 331 is not less than 60% of the maximum length of the voice coil 32 along the first direction. This arrangement fully utilizes the dimension of the voice coil 32 in the first direction to increase the size of the first suspended portion 331, thereby reducing the bending stiffness of the first suspended portion 331. This allows the first suspended portion 331 to move synchronously with the voice coil 32, which helps reduce interference between the first lead 33 and the voice coil 32 due to asynchronous movement, thus reducing the possibility of noise generation. For example, the length of the first suspended portion 331 can be 60%, 68%, 75%, 83%, or 90% of the maximum length of the voice coil 32 along the first direction.

[0039] Please see Figure 5In some embodiments, the first lead 33 further includes a first lead portion 332 connected to the first suspended portion 331 at the first support member 41. Compared to the first lead portion 332, the periphery of the first suspended portion 331 is further provided with a covering layer. The first lead portion 332 can be connected to a circuit board so that the first lead 33 can input audio electrical signals to the voice coil 32. Both the first suspended portion 331 and the first lead portion 332 can be provided with a main insulating layer (such as polytetrafluoroethylene, PTFE), and the covering layer of the first suspended portion 331 can be an additional layer disposed outside the main insulating layer. The covering layer can adjust the bending stiffness of the first suspended portion 331, making the bending stiffness of the first suspended portion 331 appropriate. On the one hand, the bending stiffness of the first suspended portion 331 will not be too large, so that the first suspended portion 331 can move synchronously with the voice coil 32, which helps to reduce interference between the first lead wire 33 and the voice coil 32 due to asynchronous movement, thereby reducing the possibility of generating noise. On the other hand, the bending stiffness of the first suspended portion 331 will not be too small, so that the first suspended portion 331 will not interfere with other components due to excessive deformation during the movement of the voice coil 32, thereby reducing the possibility of generating noise.

[0040] In some embodiments, the covering layer may be adhesive tape wrapped around the periphery of the first suspended portion 331 to make the bending stiffness of the first suspended portion 331 suitable, thereby reducing the possibility of generating noise.

[0041] In some embodiments, the coating layer is a silicone oil coating. This configuration has two advantages: firstly, the silicone oil coating can make the bending stiffness of the first suspended portion 331 suitable, thereby reducing the possibility of noise generation; secondly, since the silicone oil coating has good elasticity, it can buffer the stress of the first suspended portion 331 during bending and vibration, which helps to reduce the risk of fatigue fracture of the first suspended portion 331.

[0042] Please see Figures 3-5In some embodiments, the voice coil assembly 30 includes a second lead 34, and the frame assembly 40 includes a second support 42 located on the side of the second side 322 opposite to the first side 321. The second lead 34 connects to the voice coil 32 and is supported by the second support 42. The second lead 34 can be connected to a circuit board, and the first lead 33 and the second lead 34 form a loop to input an audio electrical signal to the voice coil 32. The first lead 33 and the second lead 34 can be located on the same side of one of the long sides of the voice coil 32. Alternatively, the first lead 33 and the second lead 34, as well as the first support 41 and the second support 42, are mirror-symmetrical with respect to a second reference plane disposed along the vibration direction of the loudspeaker 100. This configuration allows the first lead 33 and the second lead 34 to be located on different sides of the two long sides of the voice coil 32. The two long sides of the voice coil 32 are isolated between the first lead 33 and the second lead 34, which can prevent interference between the first lead 33 and the second lead 34, thereby reducing the possibility of generating noise.

[0043] This application provides an earphone. Please refer to [link / reference]. Figure 7 The headphones 500 include the speaker 100 as described above. The speaker 100 is used to convert electrical signals into mechanical vibrations, which in turn drive surrounding air molecules to form sound waves with varying density, thereby producing sound. The headphones 500 can be either open-back or in-ear headphones.

[0044] In some embodiments, such as Figure 7 , Figure 8 As shown, the headphones 500 may also include a wearing component 200. The speaker 100 is connected to the wearing component 200, which is used to place the speaker 100 in or near the user's ear so that the user can hear sound through the headphones 500. The wearing component 200 may be wrapped around the user's head, such as... Figure 8 As shown, the headphones 500 are over-ear headphones; the wearing component 200 can also be attached between the user's ear and head, such as... Figure 7 As shown, the earphone 500 is an ear-hook type earphone; the wearing component 200 can also be clipped onto the user's ear, that is, the earphone 500 is an ear clip type earphone, which is not specifically limited here.

[0045] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application.
