[0029] Embodiment 1 of the ultra-thin speaker of the present application

[0030] As attached Figure 1-4 As shown, an embodiment of the present application provides an ultra-thin speaker, comprising:

[0031] sound basin 1;

[0032] Magnet 2: arranged on the sound basin 1;

[0033] Voice coil 3 : arranged on the sound cone 1 ; the voice coil 3 generates a magnetic field when energized and interacts with the magnet 2 to generate vibration, thereby driving the sound cone 1 .

[0034] The magnet 2 and the voice coil 3 of the ultra-thin speaker of the present application are both installed on the sound cone 1. Compared with the prior art, the arrangement of parts such as the U cup is reduced, the volume of the internal parts required to be installed with the U cup is reduced, and the weight of the speaker is reduced. At the same time, the magnet 2 is directly installed on the sound cone 1, which not only ensures the sound quality, but also further reduces the thickness of the speaker, so that the height of the entire speaker is effectively reduced, making it smaller in size, easy to install, and applicable to a wide range of scenarios.

[0035] As attached Figure 3 As shown, further, the sound cone 1 is provided with a receiving groove 11 for receiving the magnet 2, and the voice coil 3 is arranged around the outside of the magnet 2. The receiving groove 11 plays a role in positioning and installing the magnet 2, which is convenient for installing the magnet 2 and is firmly installed to prevent the shaking of the magnet 2 from affecting the vibration of the sound cone 1, thereby making the ultra-thin speaker have higher loudness and better sound quality.

[0036] Furthermore, the size of the magnet 2 is not subject to any specific restrictions, and it only needs to be smaller than the size of the sound cone 1 and can be installed on the sound cone 1.

[0037] As attached Figure 3-4 As shown, further, a raised flange 12 is provided in the sound basin 1, and the flange 12 encloses the receiving groove 11, and the voice coil 3 is sleeved on the outer surface of the flange 12. The flange 12 plays a role in positioning and installing the voice coil 3, which is conducive to obtaining a better centering effect for the voice coil 3 during use, and is also conducive to improving the power that the entire speaker can withstand, so that the ultra-thin speaker has higher loudness and better sound quality.

[0038] Furthermore, in this embodiment, the voice coil 3 is mounted on the outer surface of the flange 12, which is the most ideal installation method and convenient for installation, so that the voice coil 3, magnet 2 and other parts are located on the same side end surface of the sound basin 1, which is convenient for hiding parts and controlling sound effects.

[0039] Furthermore, the magnet 2 and the voice coil 3 are fixed to the sound basin 1 by gluing or other methods, which is simple, convenient and firmly fixed.

[0040] As attached Figure 1-4As shown, further, the ultra-thin speaker also includes a terminal 4 and a brocade wire 5 for connecting the voice coil 3 and the terminal 4, and the brocade wire 5 is electrically connected to the voice coil 3 and the terminal 4 respectively. The terminal 4 is used to connect the speaker and the amplifier, and the brocade wire 5 ensures that the audio signal can be transmitted with high quality and low noise, providing clearer and more accurate sound performance, and ensuring the effect of sound quality fidelity.

[0041] As attached Figure 3 As shown, further, the voice coil 3 is provided with a main body 31 and a connecting part 32, the width of the connecting part 32 is smaller than the width of the main body 31, and the connecting part 32 is provided on one side of the lower end of the main body 31, so that the lower end of the main body 31 is formed with a connecting groove 33 located on one side of the connecting part 32, and when connected, the brocade wire 5 is partially inserted into the connecting groove 33 and electrically connected to one side of the connecting part 32, and the other side of the connecting part 32 is against the outer surface of the flange 12. It is convenient to connect the voice coil 3 and the brocade wire 5 to be electrically connected, so that the voice coil 3 is energized to generate a magnetic field and interact with the magnet 2 to generate vibration, thereby driving the sound basin 1.

[0042] Furthermore, it also includes a PCB board 41, which is electrically connected to the terminal 4, so as to facilitate the connection between the speaker and the amplifier, and facilitate wiring and control of input current, voltage, etc.

[0043] As attached Figure 1-4 As shown, further, the sound basin 1 is provided with a plurality of clamping posts 6, and a clamping space 61 for the brocade wire 5 to be clamped is formed between two of the clamping posts 6. The clamping posts 6 are a pair, and are arranged between the voice coil 3 and the terminal 4 at intervals. The clamping posts 6 play a role in positioning and installing the brocade wire 5, which is convenient for installing the brocade wire 5 and is firmly installed to prevent the shaking of the brocade wire 5 from affecting the vibration of the sound basin 1, thereby making the ultra-thin speaker have higher loudness and better sound quality.

[0044] As attached Figure 1-4 As shown, further, the ultra-thin speaker also includes a sound frame 7, and the sound basin 1 is fixed in the sound frame 7. The ultra-thin speaker also includes a connecting edge 8 arranged on the outer periphery of the sound frame 7, and a connecting hole 81 is opened on the connecting edge 8, and the terminal 4 is arranged on the connecting edge 8. The connecting edge 8 is also provided with a mounting position 82 for mounting a PCB board 41 and a terminal 4. The connecting edge 8 is integrally formed with the sound frame 7 or fixedly connected together, and the connecting edge 8 is made of soft rubber material, which is convenient for fixed installation.

[0045] Furthermore, in the prior art, the height of a 2-inch speaker is 20MM. Since the magnet 2 and the voice coil 3 of the ultra-thin speaker of the present application are both installed on the sound cone 1, taking a 4-inch speaker as an example, the overall height of the speaker of the present application is 5mm. Compared with the prior art, the thickness of the speaker is greatly reduced, so that the height of the entire speaker is effectively reduced, making it smaller in size, easy to install, and applicable to a wide range of scenarios.

[0046] Furthermore, the ultra-thin speaker of the present application can be installed on a sleep aid audio system, or on a lamp, etc. Its extremely small thickness and extremely small volume make it suitable for most audio systems and electrical appliances.

[0047] Based on the above-mentioned ultra-thin speaker, the embodiment of the present application also provides an ultra-thin speaker, including the ultra-thin speaker. The magnet 2 and the voice coil 3 of the ultra-thin speaker of the present application are both installed on the sound basin 1, which reduces the setting of parts such as U cups and reduces the volume of parts such as U cups installed inside compared with the prior art, and reduces the weight of the speaker. At the same time, the magnet 2 is directly installed on the sound basin 1, which not only ensures the sound quality, but also further reduces the thickness of the speaker, so that the height of the entire speaker is effectively reduced and the volume is small, which is convenient for installation and carrying.

[0048] Embodiment 2 of the ultra-thin speaker of the present application

[0049] The voice coil 3 in Example 1 is sleeved on the outer surface of the flange 12. Different from Example 1, in Example 2, a raised flange 12 is provided at one end of the sound basin 1 and a mounting groove 13 is correspondingly provided at the other end, and the voice coil 3 is arranged in the mounting groove 13 (not shown in the figure).

[0050] Furthermore, a raised flange 12 is provided at one end of the sound basin 1 and a mounting groove 13 is correspondingly provided at the other end. The flange 12 encloses the receiving groove 11, and the voice coil 3 is arranged in the mounting groove 13. The mounting groove 13 plays a role in positioning and installing the voice coil 3, which is conducive to obtaining a better centering effect of the voice coil 3 during use, and is also conducive to improving the power that the entire speaker can withstand, so that the ultra-thin speaker has a higher loudness and better sound quality. Compared with the voice coil 3 sleeved on the outer side of the flange 12 in the first embodiment, the voice coil 3 arranged in the mounting groove 13 in the second embodiment is closer to the magnet 2, so the ultra-thin speaker of the second embodiment emits a louder sound, and the sound effect intensity is improved.

[0051] Furthermore, the voice coil 3 may also be directly mounted on the magnet 2. The closer the voice coil 3 is to the magnet 2, the louder the sound is, thus improving the sound intensity.

[0052] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application.
