[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] This utility model provides a loudspeaker 1000, as shown in Figures 1-2. The loudspeaker 1000 includes a base 10, a speaker base 20, a positioning structure 30, and a plurality of first screws 40. The speaker base 20 is mounted on the base 10, and the plurality of first screws 40 are inserted into the speaker base 20 and the base 10 to connect the speaker base 20 and the base 10. The positioning structure 30 includes a positioning hole 31 and a positioning pin 32. The positioning hole 31 is disposed on one of the base 10 and the speaker base 20, and the positioning pin 32 is disposed on the other of the base 10 and the speaker base 20. The positioning pin 32 cooperates with the positioning hole 31 to limit the installation of the speaker base 20 on the base 10. This application can solve the problem of cumbersome assembly of the base 10 and the speaker base 20 in the prior art. The loudspeaker 1000, by setting the positioning structure 30, can reduce the installation difficulty, simplify the installation steps, and improve the assembly efficiency.

[0038] Specifically, a positioning structure 30 is provided between the base 10 and the amplifier socket 20. During installation, the positioning pin 32 cooperates with the positioning hole 31, restricting the range of motion of the amplifier socket 20 on the base 10. This ensures that the amplifier socket 20 can only move in a specific direction during installation, facilitating the insertion of the first screw 40 into the amplifier socket 20 and the base 10, allowing for quick installation of the amplifier socket 20 onto the base 10. Throughout the installation process, the assembler does not need to repeatedly adjust the relative positions of the base 10 and the amplifier socket 20 by moving freely in multiple directions, simplifying the installation process and improving assembly efficiency.

[0039] In a more specific embodiment, the base 10 is provided with a plurality of first connecting holes 11, and the amplifier base 20 is provided with a plurality of through holes 21. Each through hole 21 can be aligned with each first connecting hole 11, so that a plurality of first screws 40 can pass through a through hole 21 and connect with the first connecting hole 11 aligned with the through hole 21, thereby realizing the connection between the amplifier base 20 and the base 10. By setting the positioning pin 32 to cooperate with the positioning hole 31, the lateral movement of the amplifier base 20 on the base 10 on the horizontal plane can be restricted. The amplifier base 20 and the base 10 can only move relative to each other in the unrestricted direction. Thus, by changing the position of the amplifier base or the base in a specific single direction, the assembly personnel can make the positions of the plurality of through holes 21 and the plurality of first connecting holes 11 one by one, so that the plurality of screws 40 can be quickly inserted into the amplifier base 20 and the base 10.

[0040] In this application, the amplifier stand 20 and the base 10 together enclose a sound cavity, which is used to install the dynamic coil unit 50.

[0041] The amplifier stand 20 is used to converge sound waves and amplify sound. The amplifier stand 20 has an inlet on the side facing the base 10, which is located in the sound cavity. The amplifier stand 20 has an outlet on the side facing away from the base 10. The amplifier stand 20 also has an amplification channel inside. The inlet is connected to the outlet through the amplification channel. The moving coil unit 50 vibrates in the sound cavity to generate sound waves. The sound waves enter the amplification channel through the inlet for amplification and convergence, and are transmitted to the outlet to achieve amplification.

[0042] Referring to the figure, in one embodiment, the base 10 includes a base 12 and a washer 13. The base 12 has a receiving groove 121 on the side facing the amplifier base 20, and the washer 13 is received in the receiving groove 121. A positioning hole 31 is provided at the washer 13. The amplifier base 20 has a positioning pin 32 on the side facing the base 10, and the positioning pin 32 is inserted into the positioning hole 31. With this arrangement, the receiving groove 121 and the amplifier base 20 together enclose a sound cavity. The washer 13 is located in the sound cavity, which can effectively amplify and adjust the propagation effect of sound waves. Furthermore, by providing the positioning hole 31 at the washer 13, the positioning pin 32 can be inserted into the positioning hole 31, achieving convenient installation.

[0043] Preferably, the positioning hole 31 is located at the center of the washer 13, which facilitates the installation and alignment of the base 10 and the amplifier base 20 by the assembly personnel.

[0044] Referring to the figure, in one embodiment, the loudspeaker 1000 further includes a moving coil unit 50, which includes a magnet 51 disposed between the washer 13 and the bottom of the receiving groove 121. An opening 14 is provided on the side of the base 10 facing away from the loudspeaker base 20. The loudspeaker 1000 also includes a second screw, which passes sequentially through the opening 14 and the magnet 51, and is threadedly connected to the positioning post 32. This arrangement, with the second screw passing through the opening 14 and the magnet 51, and threadedly connected to the positioning post 32, further improves the connection stability between the loudspeaker base 20 and the base 10 through the generated tightening force. Specifically, the second screw is a screw.

[0045] It is worth mentioning that the magnet 51 is located between the washer 13 and the bottom of the receiving groove 121. The washer 13 can effectively limit the magnetic field distribution of the magnet 51, which is more conducive to the generation of sound waves by the loudspeaker 1000.

[0046] Referring to Figures 1 and 2, in one embodiment, the positioning post 32 includes a limiting section 321 and a connecting section 322. The connecting section 322 is located on the side of the limiting section 321 away from the amplifier base 20. The limiting section 321 is inserted into the positioning hole 31. The magnet 51 has a communicating hole 511, and the connecting section 322 is located in the communicating hole 511. The connecting end has a second connecting hole 3222 for threaded connection with the second screw. With this configuration, the connecting section 322 is located in the communicating hole 511 of the magnet 51, making the positioning post 32 closer to the opening 14, reducing the length of the second screw. The reduction in length can reduce the bending stress on the second screw, further improving the connection stability between the amplifier base 20 and the base 10.

[0047] In one embodiment, the outer contour of the connecting segment 322 is smaller than the inner contour of the connecting hole 511, so as to form a gap 60 space with the hole wall of the connecting hole 511. With this configuration, the gap 60 space can prevent the positioning post 32 from directly contacting the magnet 51, thereby preventing the positioning post 32 from interfering with the distribution of the magnetic field of the magnet 51 and ensuring the amplification effect of the loudspeaker 1000.

[0048] In one embodiment, the magnet 51 includes a first peripheral wall disposed relative to the sidewall of the receiving groove 121, and a movable space 70 is formed between the sidewall and the first peripheral wall. The moving coil unit 50 also includes a coil 52 and a diaphragm 53. The diaphragm 53 is located between the amplifier base 20 and the base 10. The coil 52 is sleeved on the magnet 51 and located in the movable space 70, and the coil 52 is connected to the diaphragm 53. With this configuration, when the coil 52 is energized, according to the principle of electromagnetic induction, the coil 52 moves in the magnetic field generated by the magnet 51, which drives the coil 52 to move, causing the diaphragm 53 to generate sound waves. Furthermore, confining the coil 52 to the movable space 70 ensures that the coil 52 moves in a preset direction, improving the stability and reliability of sound wave generation.

[0049] Referring to Figures 1 and 2, in one embodiment, the moving coil unit 50 further includes a diaphragm 53, and positioning posts 32 are sequentially inserted through the diaphragm 53, the washer 13, and the magnet 51. This arrangement allows the positioning posts 32 to limit the position of the diaphragm 53, helping to ensure the relative position of the diaphragm 53 and the amplifier base 20, and preventing the diaphragm 53 from shifting during vibration. Specifically, the diaphragm 53 has an inner hole 531 at its center, and the positioning posts 32 pass through the inner hole 531.

[0050] Referring to Figures 1 and 2, in one embodiment, the loudspeaker 1000 further includes a bracket 54, which is mounted on the coil 52 and located within the movement space 70. This arrangement enhances the overall strength of the coil 52, prevents deformation, and ensures stability during movement.

[0051] Preferably, the bracket 54 is arranged around the coil 52 to further improve support for the coil 52.

[0052] Referring to Figures 1 and 2, in one embodiment, the loudspeaker 1000 further includes a sealing ring 80, which is sandwiched between the loudspeaker base 20 and the base 10, and surrounds the positioning hole 31. This arrangement allows the sealing ring 80 to seal the positioning hole 31, preventing sound leakage through the positioning hole 31, improving the sealing of the sound cavity, and ensuring the amplification effect.

[0053] Referring to the figure, in one embodiment, the base 10 has a mounting groove 15 on the side facing away from the amplifier base 20. The mounting groove 15 is used to limit the mounting of a temperature sensor. With this configuration, the mounting groove 15 can limit the mounting of the temperature sensor, making it easier for the temperature sensor to detect the internal temperature of the loudspeaker 1000, thereby improving the accuracy and stability of temperature measurement.

[0054] Preferably, the opening 14 is located at the bottom of the mounting groove 15. In this way, the mounting groove 15 can accommodate part of the second screw and also install the temperature sensor, improving the space utilization of the base 10.

[0055] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
