Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and more specifically, to a new type of super-linear loudspeaker. Background Art

[0002] A super-linear loudspeaker is a kind of loudspeaker with high performance and high fidelity, which can reduce the distortion of sound and provide a sound reproduction closer to the original audio signal. It usually adopts a special magnetic circuit design and voice coil structure. By optimizing the magnetic field distribution and the movement mode of the voice coil, the loudspeaker can convert electrical energy into sound energy more efficiently when working. Compared with traditional loudspeakers, super-linear loudspeakers can provide more accurate and clear sound output in a wider frequency range.

[0003] However, the existing super-linear loudspeakers have the following problems when in use:

[0004] When it is necessary to output audio signals with a large volume and large amplitude, components such as the diaphragm and voice coil of the loudspeaker may show unstable swaying phenomena. Such swaying not only affects the accuracy and quality of the sound, but also causes additional stress on the overall structure of the loudspeaker. Over time and with the continuous large-amplitude state, some vulnerable parts of the loudspeaker may not be able to withstand this stress, and thus there is a risk of fracture, resulting in damage to the loudspeaker and inability to work properly.

[0005] The utility model can play a role in stably outputting high-quality audio in various working states and avoiding the fracture of the loudspeaker. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the technical problems put forward in the above background art, and provide a new type of super-linear loudspeaker.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A new type of super-linear loudspeaker, including: a base, a diaphragm is fixedly installed on the upper end of the base, an outer elastic arm is fixedly installed on the upper surface of the diaphragm, a connecting seat, a voice coil and a collar are respectively arranged between the base and the diaphragm, the super-linear loudspeaker is formed by combining the base, the diaphragm, the outer elastic arm, the connecting seat, the voice coil and the collar, an inner elastic arm is fixedly connected to the inner side of the outer elastic arm, and a connecting elastic arm is fixedly installed between the outer elastic arm and the inner elastic arm.

[0008] Further preferred scheme: An installation groove is opened inside the base, the base is hollow, the connecting seat is embedded in the installation groove, and the bottom of the connecting seat is located in the middle of the bottom of the base.

[0009] Further preferred solution: The periphery of the diaphragm is attached to and fixedly connected with the outer elastic arm, the inner side of the diaphragm is attached to and fixedly connected with the inner elastic arm, and the bottom of the connecting elastic arm is attached to the upper end of the diaphragm.

[0010] Further preferred solution: A limiting plate is fixedly installed at the upper end of the connecting seat, a voice coil is fixedly installed in the middle of the connecting seat, and the upper end of the voice coil is movably connected with the middle of the bottom of the diaphragm.

[0011] Further preferred solution: A collar is arranged around the surface of the voice coil, the inner side of the collar is attached to and fixedly connected with the outer surface of the voice coil.

[0012] Further preferred solution: The outer surface of the collar is movably connected with the inner side of the limiting plate.

[0013] Beneficial effects:

[0014] 1. By providing an outer elastic arm, when the voice coil moves under the action of an audio current, the diaphragm vibrates accordingly. The outer elastic arm is located around the periphery of the diaphragm and can provide a large range of support and restriction during the vibration of the diaphragm. It can prevent the diaphragm from vibrating excessively and avoid the risk of damage caused by too large an amplitude. At the same time, after the vibration ends, the outer elastic arm uses its elastic restoring force to quickly pull the diaphragm back to the initial position to prepare for the next vibration.

[0015] 2. By providing an inner elastic arm, the inner elastic arm is located at a position close to the center on the inner side of the diaphragm and can more finely adjust the local vibration of the diaphragm. Due to its position close to the center of the diaphragm, it is more effective in controlling high-frequency vibrations. It can improve the high-frequency response of the speaker, make high-frequency sounds clearer and more accurate, and enhance the detail performance. When the voice coil drives the diaphragm to vibrate, the inner elastic arm can quickly adjust the local vibration state of the diaphragm according to the changes in high-frequency signals to ensure the quality of high-frequency sounds.

[0016] 3. By providing a connecting elastic arm, the connecting elastic arm connects the outer elastic arm and the inner elastic arm and plays a role in transmitting and balancing stress. When the diaphragm vibrates in different directions, the connecting elastic arm can effectively transmit and balance the stress between the outer elastic arm and the inner elastic arm to ensure that the vibration of the diaphragm in all directions can be evenly controlled. This can make the sound emitted by the speaker more stable and balanced and reduce distortion caused by uneven stress.

[0017] 4. By providing a collar and a limiting plate, the collar is arranged around the voice coil, fits and is fixedly connected to the outer surface of the voice coil, providing additional support and protection for the voice coil. When the voice coil vibrates under the action of the magnetic field force, the collar can limit the lateral displacement of the voice coil, preventing the voice coil from shifting or deforming during vibration. The limiting plate can ensure that the collar moves within a certain range, avoiding excessive movement of the collar and affecting the normal operation of the speaker. At the same time, the way the collar is movably connected to the limiting plate also avoids stress concentration caused by fixed connection between the collar and the limiting plate, improving the reliability and service life of the speaker;

[0018] 5. In summary, for this new type of super-linear speaker, by providing structures such as an outer elastic arm, an inner elastic arm, and a connecting elastic arm, while increasing the amplitude of the speaker, the elastic arm system can effectively suppress the swaying motion of the speaker. The large-range support and limitation of the outer elastic arm, the fine adjustment of the inner elastic arm, and the stress balance of the connecting elastic arm work together to enable the diaphragm to maintain a stable motion trajectory even during large-amplitude vibration. This greatly reduces the distortion requirements of the speaker, allowing the speaker to maintain high-quality sound output while outputting a larger volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will combine the accompanying drawings in the embodiments of the present invention Figures 1-3 to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0024] Please refer to Figures 1-3, in the embodiment of the present utility model, a novel super-linear loudspeaker includes: a base 1, a diaphragm 2 is fixedly installed on the upper end of the base 1, an outer elastic arm 3 is fixedly installed on the upper surface of the diaphragm 2, a connecting seat 4, a voice coil 5 and a collar 6 are respectively arranged between the base 1 and the diaphragm 2. The super-linear loudspeaker is formed by combining the base 1, the diaphragm 2, the outer elastic arm 3, the connecting seat 4, the voice coil 5 and the collar 6. An inner elastic arm 301 is fixedly connected to the inner side of the outer elastic arm 3, and a connecting elastic arm 302 is fixedly installed between the outer elastic arm 3 and the inner elastic arm 301. The base 1 serves as the support structure of the entire loudspeaker, providing a stable installation foundation for other components, and at the same time playing a certain electromagnetic shielding role to reduce the interference of external electromagnetic fields on the internal components of the loudspeaker. Then, the connecting seat 4 is embedded and installed inside the base 1, the voice coil 5 is installed in the middle of the inside of the connecting seat 4, and at the same time, the collar 6 is installed around the outer surface of the voice coil 5. The collar 6 can play the role of fixing the position of the voice coil 5, protecting the voice coil 5, and at the same time can limit the lateral movement of the voice coil 5 to ensure the accurate position of the voice coil 5 in the magnetic field, thereby improving the performance stability of the loudspeaker. Then, above the voice coil 5, the diaphragm 2 is installed, and the outer elastic arm 3 is fixedly installed on the periphery of the upper surface of the diaphragm 2. The inner elastic arm 301 is installed within the inner ring range of the diaphragm 2, and the two elastic arms are directly fixedly connected by the connecting elastic arm 302. When the voice coil 5 is working, the diaphragm 2 vibrates to push the air to generate sound waves, converting the electrical signal into a sound signal. During the vibration process, the outer elastic arm 3 can limit its movement range to prevent damage caused by excessive vibration, and at the same time help the diaphragm 2 quickly return to the initial position after the vibration ends. It works together with the inner elastic arm 301 and the connecting elastic arm 302 to jointly adjust the vibration characteristics of the diaphragm 2 to achieve more accurate and stable sound output. At the same time, the inner elastic arm 301 is usually located near the center of the diaphragm 2, and can more finely adjust the local vibration of the diaphragm 2, thereby improving the high-frequency response and detail performance of the loudspeaker. The connecting elastic arm 302 can transmit and balance the stress between the outer elastic arm 3 and the inner elastic arm 301 to ensure that the vibration of the diaphragm 2 in all directions can be effectively controlled.

[0025] In the embodiment of the present utility model, an installation groove 101 is opened inside the base 1. The base 1 is provided in a hollow shape. The connecting seat 4 is embedded and installed in the installation groove 101. The bottom of the connecting seat 4 is located in the middle of the bottom of the base 1. A limiting plate 401 is fixedly installed at the upper end of the connecting seat 4. The voice coil 5 is fixedly installed in the middle of the inside of the connecting seat 4. The upper end of the voice coil 5 is movably connected to the middle of the bottom of the diaphragm 2. The size and shape of the installation groove 101 match those of the connecting seat 4, enabling the connecting seat 4 to be accurately embedded therein. This embedded design can improve the installation stability of the connecting seat 4 and prevent it from loosening or displacing during the operation of the loudspeaker. The bottom of the connecting seat 4 is located in the middle of the bottom of the base 1, better balancing the center of gravity of the loudspeaker and improving the stability of the loudspeaker. The limiting plate 401 fixedly installed at the upper end of the connecting seat 4 can limit the vibration range of the voice coil 5, protecting the voice coil 5 and other components to a certain extent and improving the reliability of the loudspeaker.

[0026] In the embodiment of the present utility model, the periphery of the diaphragm 2 is in contact with and fixedly connected to the outer elastic arm 3. The inner side surface of the diaphragm 2 is in contact with and fixedly connected to the inner elastic arm 301. The bottom of the connecting elastic arm 302 is in contact with the upper end of the diaphragm 2. The elastic arms are all made of flexible materials and have a certain flexibility. Therefore, the periphery of the diaphragm 2 is in contact with and fixedly connected to the outer elastic arm 3, ensuring that when the diaphragm 2 vibrates, the outer elastic arm 3 can closely follow the movement of the diaphragm 2, providing stable support and elastic restoring force for the diaphragm 2. At the same time, the inner side surface of the diaphragm 2 is in contact with and fixedly connected to the inner elastic arm 301, enabling the inner elastic arm 301 to more directly affect the local vibration of the diaphragm 2. The inner elastic arm 301 is usually located near the center of the diaphragm 2 and can perform more precise control of high-frequency vibration. The bottom of the connecting elastic arm 302 is in contact with the upper end of the diaphragm 2, playing the role of connecting the outer elastic arm 3 and the inner elastic arm 301, and also providing additional support for the diaphragm 2. This contact method allows the connecting elastic arm 302 to better sense the vibration of the diaphragm 2, thereby more effectively transmitting and balancing the stress between the outer elastic arm 3 and the inner elastic arm 301, and at the same time suppressing the swaying movement of the speaker while increasing the amplitude of the speaker, meeting the requirement of reducing distortion.

[0027] In the embodiment of the present utility model, a collar 6 is arranged around the surface of the voice coil 5. The inner side surface of the collar 6 is in contact with and fixedly connected to the outer surface of the voice coil 5. The outer surface of the collar 6 is movably connected to the inner side surface of the limiting plate 401. The collar 6 is arranged around the voice coil 5 and is in contact with and fixedly connected to its outer surface, which can provide additional support and protection for the voice coil 5. When the voice coil is working, it will vibrate due to the action of the magnetic force. The collar 6 can limit the lateral displacement of the voice coil 5, preventing the voice coil 5 from deviating or deforming during vibration. The outer surface of the collar 6 is movably connected to the inner side surface of the limiting plate 401. This connection method allows the collar 6 to move relative to the limiting plate 401 within a certain range. When the voice coil 5 vibrates, the collar 6 can move along with the voice coil 5, and the limiting plate 401 plays the role of limiting the movement range of the collar 6, while avoiding excessive friction between the collar 5 and the limiting plate 401, reducing energy loss and wear, and also preventing stress concentration caused by the fixed connection between the collar 6 and the limiting plate 401, improving the reliability and service life of the speaker.

[0028] Working principle: When an audio current is input into the speaker, the current enters the voice coil 5 through the connection base 4. Since the voice coil 5 is in a magnetic field, according to the principle of electromagnetic induction, the voice coil 5 is subjected to the action of the Ampere force in the magnetic field and generates motion. The motion of the voice coil 5 drives the diaphragm 2 that is movably connected to it to vibrate. During the vibration of the diaphragm 2, the surrounding air is pushed, thereby generating sound waves, converting the electrical signal into a sound signal. When the diaphragm 2 vibrates, the outer elastic arm 3, the inner elastic arm 301, and the connecting elastic arm 302 work together to provide support and elastic restoring force for the diaphragm 2, limit the movement range of the diaphragm 2, prevent damage caused by excessive vibration, and help the diaphragm 2 quickly return to the initial position after the vibration ends. The inner elastic arm 301 is located near the center of the diaphragm 2 and can more finely adjust the local vibration of the diaphragm, improving the high-frequency response and detail performance of the speaker. At the same time, the collar 6 fits and is fixedly connected to the outer surface of the voice coil 5, providing additional support and protection for the voice coil 5, limiting the lateral displacement of the voice coil 5, ensuring the accurate position of the voice coil 5 in the magnetic field, and improving the performance stability of the speaker. The outer surface of the collar 6 is movably connected to the inner side surface of the limiting plate 401. When the voice coil 5 vibrates, the collar 6 can move along with the voice coil, while the limiting plate 401 limits the movement range of the collar 6, avoiding excessive friction between the collar 6 and the limiting plate 401, reducing energy loss and wear, preventing stress concentration, and improving the reliability and service life of the speaker.
