Description

Technical Field

[0001] This utility model belongs to the field of loudspeakers, specifically relating to a loudspeaker and bone conduction headphones that are resistant to vibration interference. Background Technology

[0002] Bone conduction loudspeakers work by inputting varying audio signals into the voice coil, causing the voice coil to generate electromagnetic force under the influence of a magnet's magnetic field, thus making the loudspeaker vibrate. The vibrating loudspeaker acts directly on the skull (temporal bone), and the vibration is transmitted through the bone to the cochlea (inner ear), where it is ultimately perceived by the auditory nerve.

[0003] Existing loudspeakers typically include a housing, a diaphragm, a magnet, and a voice coil. The voice coil is mounted on the housing, and the magnet is mounted on the diaphragm, which is connected to the housing. The voice coil is usually arranged around the outer periphery of the magnet, so that the magnetic field generated by the voice coil through the audio signal interacts with the magnetic field generated by the magnet, causing the diaphragm and magnet to vibrate together.

[0004] One issue is that the magnetic field generated by the voice coil is relatively dispersed, resulting in weaker vibration intensity in existing loudspeakers. Utility Model Content

[0040] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0041] Example 1:

[0042] like Figures 1-3 As shown, this utility model discloses a vibration-resistant loudspeaker, comprising:

[0043] Outer shell 1;

[0044] The voice coil structure 2 is formed by spiral winding of wire, and the voice coil structure 2 is fixed relative to the outer shell 1.

[0045] The reinforcing component 3 is fixedly disposed relative to the outer shell 1. The reinforcing component 3 is located on the inner periphery of the voice coil structure 2 and has a cylindrical reinforcing part 31.

[0046] The first vibrating plate 41, the fixing part 71 of the first vibrating plate 41 and the outer shell 1 are fixedly arranged;

[0047] The first solid magnetic structure 51 is disposed on the vibration part 73 of the first vibrating plate 41;

[0048] The first solid magnetic structure 51 and the reinforcing part 31 are located on both sides of the vibrating part 73 of the first vibrating plate 41.

[0049] Therefore, 1. An audio signal is transmitted through the voice coil structure 2 to generate an electromagnetic field, which interacts with the solid magnetic field of the first solid magnetic structure 51 to achieve the vibration of the first vibrating plate 41. 2. The reinforcement part 31 built into the inner circumference of the voice coil structure 2 is provided to guide the electromagnetic field generated by the voice coil structure 2, making the electromagnetic field more concentrated, thereby cooperating with the first solid magnetic structure 51 to enhance the interaction force and enhance the vibration intensity of the first vibrating plate 41. 3. Since the reinforcement part 31 is built into the inner circumference of the voice coil structure 2 and occupies the space on the side of the first vibrating plate 41 facing the voice coil structure 2, in order to ensure the effectiveness of the vibration, the first solid magnetic structure 51 is set on the side of the first vibrating plate 41 away from the reinforcement part 31, so that the first solid magnetic structure 51 will not interfere with the reinforcement part 31 during the vibration process.

[0050] Specifically, the outer shell 1 is cylindrical in the vertical direction, so that a cylindrical assembly cavity 11 is formed inside the outer shell 1. The voice coil structure 2, the reinforcing member 3, the first vibrating plate 41 and the first solid magnet structure 51 are all disposed in the assembly cavity 11, so that the internal structure can be protected by the outer shell 1.

[0051] In addition, the upper and lower ends of the assembly cavity 11 are provided with a first opening 111 and a second opening 112 through the outer shell 1. The outer shell 1 is provided with a sealing end cap 61 for closing the first opening 111 and a PCB 62 for closing the second opening 112. The voice coil structure 2 is electrically connected to the PCB 62.

[0052] Therefore, by further sealing the first opening 111 and the second opening 112 by sealing the end cap 61 and pcb62, the internal space of the assembly cavity 11 is less susceptible to external physical interference, making the internal vibration more stable.

[0053] Specifically, the outer peripheral wall of the voice coil structure 2 and the inner peripheral wall of the assembly cavity 11 are fixedly connected by means of adhesive bonding; while the reinforcing member 3 is inserted into the inner peripheral wall of the voice coil structure 2, and the outer peripheral wall of the reinforcing member 3 and the inner peripheral wall of the voice coil structure 2 are fixedly connected by means of adhesive bonding, so that the outer shell 1, the voice coil structure 2, and the reinforcing member 3 are arranged and connected inward in a compliant manner, making the overall structure more orderly.

[0054] In addition, the inner peripheral wall of the assembly cavity 11 is provided with a first positioning part 12 that protrudes inward at the upper end of the voice coil structure 2, and the outer peripheral wall of the reinforcing member 3 is provided with a second positioning part 32 that protrudes outward at the lower end of the voice coil structure 2.

[0055] Therefore, the voice coil structure 2 is inserted into the assembly cavity 11 through the second opening 112 facing upwards and positioned by abutting against the first positioning part 12. Then, the reinforcing member 3 is inserted into the assembly cavity 11 through the second opening 112 facing upwards and inserted into the voice coil structure 2 from the lower end facing upwards. Finally, it is positioned by abutting against the lower end of the voice coil structure 2 by the second positioning part 32.

[0056] Specifically, the reinforcing member 3 includes a cylindrical main body 33; the outer peripheral wall of the main body 33 and the inner peripheral wall of the voice coil structure 2 are fixedly connected; the reinforcing part 31 is located on the inner periphery of the main body 33, and the outer peripheral wall of the reinforcing part 31 and the inner peripheral wall of the main body 33 are fixedly connected by an integrally formed annular connecting piece 331; the second positioning part 32 is integrally formed on the lower end of the outer peripheral wall of the main body 33; wherein, the first vibrating piece 41 is disposed on the upper end of the main body 33.

[0057] More preferably, a second vibrating plate 42 is provided at the lower end of the main body 33, and a second solid magnetic structure 52 is provided on the lower side of the second vibrating plate 42.

[0058] Therefore, the electromagnetic field generated by the voice coil structure 2 not only acts on the first solid magnetic structure 51 to realize the vibration of the first vibrating plate 41, but also acts on the second solid magnetic structure 52 to realize the vibration of the second vibrating plate 42, thereby enhancing the vibration intensity under the dual action of the first vibrating plate 41 and the second vibrating plate 42.

[0059] It should be noted that both the first vibrating plate 41 and the second vibrating plate 42 include a fixing part 71, a vibrating part 73 and a connecting part 72. The fixing part 71 is arranged in a ring shape, the vibrating part 73 is located on the inner periphery of the fixing part 71, and the connecting part 72 fixes the fixing part 71 and the vibrating part 73 together by integral molding.

[0060] In other embodiments, the second vibrating plate 42 and the second solid magnetic structure 52 may be omitted, and the vibration output may be achieved solely through the first vibrating plate 41 and the first solid magnetic structure 51.

[0061] Example 2:

[0062] like Figures 4-6 As shown, this utility model discloses a vibration-resistant loudspeaker, comprising:

[0063] Outer shell 1;

[0064] The voice coil structure 2 is formed by spiral winding of wire, and the voice coil structure 2 is fixed relative to the outer shell 1.

[0065] The reinforcing component 3 is fixedly disposed relative to the outer shell 1. The reinforcing component 3 is located on the inner periphery of the voice coil structure 2 and has a cylindrical reinforcing part 31.

[0066] The first vibrating plate 41, the fixing part 71 of the first vibrating plate 41 and the outer shell 1 are fixedly arranged;

[0067] The first solid magnetic structure 51 is disposed on the vibration part 73 of the first vibrating plate 41;

[0068] The first solid magnetic structure 51 and the reinforcing part 31 are located on both sides of the vibrating part 73 of the first vibrating plate 41.

[0069] Therefore, 1. An audio signal is transmitted through the voice coil structure 2 to generate an electromagnetic field, which interacts with the solid magnetic field of the first solid magnetic structure 51 to achieve the vibration of the first vibrating plate 41. 2. The reinforcement part 31 built into the inner circumference of the voice coil structure 2 is provided to guide the electromagnetic field generated by the voice coil structure 2, making the electromagnetic field more concentrated, thereby cooperating with the first solid magnetic structure 51 to enhance the interaction force and enhance the vibration intensity of the first vibrating plate 41. 3. Since the reinforcement part 31 is built into the inner circumference of the voice coil structure 2 and occupies the space on the side of the first vibrating plate 41 facing the voice coil structure 2, in order to ensure the effectiveness of the vibration, the first solid magnetic structure 51 is set on the side of the first vibrating plate 41 away from the reinforcement part 31, so that the first solid magnetic structure 51 will not interfere with the reinforcement part 31 during the vibration process.

[0070] Specifically, the outer shell 1 includes a third magnetic structure 13, which is arranged in a ring shape to form a first inner cavity 131 on the inner periphery of the third magnetic structure 13. The voice coil structure 2 is at least partially disposed in the first inner cavity 131. The fixing part 71 of the first diaphragm 41 is fixedly disposed at the upper end of the third magnetic structure 13. The first magnetic structure 51 is located on the side of the first diaphragm 41 away from the first inner cavity 131.

[0071] Therefore, the changing electromagnetic field generated by the voice coil structure 2 is superimposed on the constant magnetic field generated by the third solid magnetic structure 13 to drive the first solid magnetic structure 51 to vibrate, and the vibration intensity is greater. In addition, the third solid magnetic structure 13 also provides a mounting position for the first vibrating plate 41, so that no other structure is needed to install the first vibrating plate 41, and the overall structure is simpler.

[0072] In addition, the outer shell 1 in this embodiment also includes a fourth magnetic structure 14, which is located at the lower end of the third magnetic structure 13. The fourth magnetic structure 14 is arranged in a ring shape to form a second inner cavity 141 on the inner periphery of the fourth magnetic structure 14, and the voice coil structure 2 is at least partially disposed in the second inner cavity 141.

[0073] Correspondingly, it also includes:

[0074] The second vibrating plate 42, the fixing part 71 of the second vibrating plate 42 is fixedly disposed at the lower end of the fourth solid magnetic structure 14;

[0075] The second magnetic structure 52 is disposed on the vibration part 73 of the second vibrating plate 42, and the second magnetic structure 52 is located on the lower side of the second vibrating plate 42.

[0076] Therefore, the electromagnetic field generated by the voice coil structure 2 not only combines with the magnetic field generated by the third solid magnetic structure 13 to act on the first solid magnetic structure 51 to realize the vibration of the first vibrating plate 41, but also combines with the magnetic field generated by the fourth solid magnetic structure 14 to act on the second solid magnetic structure 52 to realize the vibration of the second vibrating plate 42, thereby enhancing the vibration intensity under the dual action of the first vibrating plate 41 and the second vibrating plate 42.

[0077] Specifically, the reinforcing member 3 includes an assembly part 34 surrounding the reinforcing part 31, and a third magnetic structure 13 and a fourth magnetic structure 14 are respectively fixedly disposed on both sides of the assembly part 34.

[0078] The assembly part 34 and the third magnetic structure 13 are fixedly connected by glue or the like, the assembly part 34 and the fourth magnetic structure 14 are fixedly connected by glue or the like, the first vibrating plate 41 and the third magnetic structure 13 are fixedly connected by glue or the like, and the second vibrating plate 42 and the fourth magnetic structure 14 are fixedly connected by glue or the like.

[0079] Preferably, the voice coil structure 2 includes a first voice coil portion 21 disposed in the first inner cavity 131 and a second voice coil portion 22 disposed in the second inner cavity 141; the reinforcing portion 31 includes a first portion 311 and a second portion 312, the first portion 311 being inserted into the first inner cavity 131 from the lower end of the third magnetized structure 13 upward, and the second portion 312 being inserted into the second inner cavity 141 from the upper end of the fourth magnetized structure 14 downward.

[0080] This causes the first voice coil portion 21 to conduct magnetism in conjunction with the first part 311 and act on the first solid magnetic structure 51, and the second voice coil portion 22 to conduct magnetism in conjunction with the second part 312 and act on the second solid magnetic structure 52, so that the interaction is closer together to improve the vibration intensity of each vibrating plate.
