Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and more particularly to a novel anti-slip super-linear loudspeaker. Background Art

[0002] A speaker is a modern electroacoustic component, also known as a loudspeaker, that converts electrical signals into sound. This type of speaker is widely used in various electronic devices and audio systems, including car speakers and audio equipment. Its sound production principle is based on the conversion of electrical energy into sound. When electrical energy is transferred to a coil, the coil interacts with the magnetic field of a magnet, causing the disc to vibrate, thereby producing sound. This device is very common in both electronic and electrical equipment and is a critical component for ensuring communication, entertainment, and warning signal transmission. As consumers pursue a higher bass sound quality, customers are demanding a larger amplitude for speakers to achieve better bass effects.

[0003] However, the existing speakers have the following problems when in use:

[0004] The FPC in traditional superlinear speakers is bonded to the bottom or top of the voice coil. Since the speaker needs the voice coil to vibrate frequently to produce sound, the vibration of the voice coil will drive the FPC to move up and down synchronously, causing the FPC to easily detach from the voice coil, creating the risk of coil decoupling.

[0005] The utility model can fix a proportionally enlarged connecting plate on the bottom of the FPC and connect the connecting plate to the bottom of the voice coil, thereby effectively improving the speaker power and reducing low-frequency distortion under high-power conditions. Utility Model Content

[0006] The present invention aims to solve the technical problems raised by the above-mentioned background technology and provide a novel anti-ring-off super-linear speaker.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a novel anti-coil-off super-linear speaker, comprising: a shell, a bracket fixedly mounted on the bottom of the shell, a basin fixedly connected to the bottom of the bracket, a voice coil arranged in the middle of the bracket, connecting plates arranged on the left and right sides of the bottom of the voice coil, a washer arranged below the voice coil, a magnet arranged below the washer, the shell, bracket and basin forming a complete speaker shell, the voice coil, connecting plate, washer and magnet all being mounted inside the speaker shell formed by the shell, bracket and basin, an embedded groove being provided on the left and right sides of the bottom of the voice coil, and the upper end of the connecting plate being fitted with the embedded groove.

[0008] A further preferred solution is that the housing is located at the uppermost end, and a diaphragm is provided inside the housing.

[0009] A further preferred solution is that connecting columns are fixedly installed at the four corners of the bottom of the bracket, and the connecting columns are embedded in the interior of the connecting plate and fit therewith.

[0010] A further preferred solution is that an installation area is provided in the middle of the upper end of the basin frame, a magnet is fixedly installed in the installation area, support frames are fixedly installed on both left and right sides of the upper end of the basin frame, and the support frames are fixedly connected to the bottom of the connecting plate.

[0011] A further preferred solution is that an FPC is fixedly mounted on the upper end of the connecting plate, the FPC is similar in shape to the connecting plate, and the volumes of the FPC and the connecting plate are proportional, and the innermost side of the upper end of the connecting plate is fixedly connected to the embedded groove.

[0012] A further preferred solution: the connecting plate and the outermost front and rear sides of the upper end of the FPC are both provided with connecting holes, the connecting holes are matched with connecting columns, and the connecting columns pass through the connecting holes on the FPC and the connecting plate in sequence and are fixedly connected thereto.

[0013] Beneficial effects:

[0014] 1. By providing connecting posts and connecting holes, the connecting posts fit into the inside of the connecting plate, and the connecting holes are used to tightly fix the FPC, connecting plate, and bracket together. This precise connection method ensures the accuracy of the spatial position of each component and avoids structural instability caused by relative displacement between components. The connecting posts pass through the connecting holes on the FPC and connecting plate in sequence, forming a stable electrical signal transmission channel. This fixed connection method reduces interference and loss of electrical signals during transmission, ensuring that the signal can be accurately transmitted from the external circuit to the voice coil, and improving the transmission efficiency of electrical signals.

[0015] 2. The embedded slot, connecting plate, and FPC are similar in shape and proportional in size to the connecting plate. The FPC is fixedly mounted on the connecting plate, leaving a blank area where the FPC and the connecting plate meet. This blank area, through its fixed connection with the embedded slot, securely connects the connecting plate to the voice coil. When the speaker is operating, the voice coil vibrates frequently, but the tight connection between the embedded slot and the connecting plate effectively prevents loosening or displacement of the voice coil. This not only reduces structural instability caused by vibration, but also lowers the probability of sound distortion and noise, enabling the speaker to more accurately reproduce sound signals and provide a better audio experience.

[0016] 3. In summary, this new type of anti-coil unseating super-linear speaker is equipped with structures such as connecting columns, voice coils, connecting plates and FPC. The connecting columns firmly fix the bracket, connecting plate and FPC together. They are distributed at the four corners of the bottom of the bracket, ensuring that the force on the entire structure is uniform and can effectively withstand the vibration and external force impact generated when the speaker is working. The embedded groove at the bottom of the voice coil fits with the upper end of the connecting plate, making the connection between the voice coil and the connecting plate tighter. During the operation of the speaker, the frequent vibration of the voice coil will not cause loosening or displacement between it and the connecting plate, thereby ensuring the stability and accuracy of the sound. The FPC is similar in shape to the connecting plate and its volume is proportionally scaled, which not only reduces space waste but also improves the transmission stability of electrical signals.

[0022] The following is a combination of the appended examples of the present invention Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0023] See also Figure 1-4In the embodiment of the present invention, a new type of anti-coil super linear speaker includes: a shell 1, a bracket 2 is fixedly installed on the bottom of the shell 1, a basin frame 3 is fixedly connected to the bottom of the bracket 2, a voice coil 4 is arranged in the middle of the bracket 2, connecting plates 5 are arranged on the left and right sides of the bottom of the voice coil 4, a washer 6 is arranged under the voice coil 4, and a magnet 7 is arranged under the washer 6. The shell 1, the bracket 2 and the basin frame 3 form a complete speaker shell, and the voice coil 4, the connecting plate 5, the washer 6 and the magnet 7 are all installed inside the speaker shell composed of the shell 1, the bracket 2 and the basin frame 3. The voice coil 4 is provided with an embedded groove 401 on the left and right sides of the bottom of the voice coil 4, and the upper end of the connecting plate 5 is matched with the embedded groove 401. The shell 1 is located at the uppermost end, and a diaphragm is arranged inside the shell 1. The shell 1 serves as the topmost protective structure of the speaker and can protect the bottom and other parts. Other components are protected, and the bracket 2 at the bottom is set up with a hollow structure. The voice coil 4 and the connecting plate 5 are installed inside the bracket 2, and then the washer 6 and the magnet 7 are installed at the bottom of the connecting plate 5. Finally, the basin frame 3 is installed at the bottom and connected to the bracket 2, so that it can protect the internal components. Since the voice coil 4 can convert the input electrical signal into mechanical vibration, thereby driving the diaphragm to produce sound, it needs to vibrate frequently during operation. Therefore, embedded grooves 401 are opened on the left and right sides of the bottom of the voice coil 4, which fit with the connecting plate 5, improve the connection stability between the connecting plate 5 and the voice coil 4, and prevent the voice coil from loosening or displacement during operation, which helps to reduce sound distortion and noise, and enables the speaker to more accurately restore the sound signal and provide a better audio experience.

[0024] In the embodiment of the present invention, the four corners of the bottom of the bracket 2 are fixedly installed with connecting columns 201, and the connecting columns 201 are embedded in the interior of the connecting plate 5 and fit therewith. The connecting plate 5 and the outermost front and rear sides of the upper end of the FPC501 are provided with connecting holes 502, and the connecting holes 502 are matched with the connecting columns 201. The connecting columns 201 pass through the connecting holes 502 on the FPC501 and the connecting plate 5 in sequence and are fixedly connected thereto. The upper end of the connecting plate 5 is fixedly installed with the FPC501. The FPC501 is similar in shape to the connecting plate 5, and the volume of the FPC501 is proportional to that of the connecting plate 5. The FPC501 undertakes the important task of transmitting electrical signals in the speaker and is fixed thereto. It is installed on the connecting plate 5, and the appearance and shape of the FPC501 are consistent with the connecting plate 5. In terms of size, it is proportionally scaled by the connecting plate 5, so that the FPC501 can fit better on the connecting plate, reducing space waste and facilitating installation and fixation. Then, a connecting hole 502 is opened at the same position of the FPC501 and the connecting plate 5. When the forward bracket 2 and the connecting plate 5 are installed, the connecting column 201 is sequentially passed through the connecting hole 502 on the FPC501 and the connecting hole 502 on the connecting plate 5 to achieve a fixed connection between the three, ensuring that the electrical signal can be stably transmitted from the external circuit to the voice coil 4, thereby driving the voice coil 4 to produce sound.

[0025] In the embodiment of the present invention, an installation area 301 is provided in the middle of the upper end of the basin frame 3, and a magnet 7 is fixedly installed in the installation area 301. Support frames 302 are fixedly installed on the left and right sides of the upper end of the basin frame 3, and the support frames 302 are fixedly connected to the bottom of the connecting plate 5. The installation area 301 in the middle of the upper end of the basin frame 3 provides a stable installation position for the magnet 7, so that the magnet 7 can accurately cooperate with components such as the voice coil 4 and the washer 6 to form a complete magnetic circuit system, providing the necessary magnetic field for the normal operation of the speaker. Then, the support frames 302 are fixedly installed on the left and right sides of the upper end of the basin frame 3. On the one hand, they are fixedly connected to the bottom of the connecting plate 5 to provide stable support for the connecting plate 5. On the other hand, they also connect the basin frame 3 with other components of the speaker, thereby enhancing the stability of the entire speaker structure.

[0026] In this embodiment of the present invention, the innermost portion of the upper end of the connecting plate 5 is fixedly connected to the embedded groove 401. Because the FPC 501 is proportionally scaled to the connecting plate 5, a gap is left on the upper end of the connecting plate 5, near the voice coil 4. This gap allows for connection to the embedded groove 401 at the bottom of the voice coil 4, helping to improve the stability of the connection between the voice coil 4 and the connecting plate 5. During speaker operation, the voice coil 4 generates strong vibrations, and this connection method can withstand such vibrations, reducing the risk of loosening and displacement, thereby ensuring stable speaker performance. The presence of the gap also creates a tighter connection, reducing loss and interference during signal transmission, improving signal transmission quality, and thus enhancing the speaker's sound quality and sensitivity.

[0027] Working principle: When assembling the speaker, prepare the shell 1, bracket 2, and basin frame 3. The shell 1 is located at the top and serves as the top protective structure of the speaker. The bracket 2 is a hollow structure. The voice coil 4 is installed in the middle of the bracket 2. The embedded grooves 401 on the left and right sides of the bottom of the voice coil 4 are matched with the upper end of the connecting plate 5 for connection to improve the connection stability. The FPC501 is fixedly installed on the upper end of the connecting plate 5. The FPC501 is similar in shape to the connecting plate 5 and the volume is proportional. A connecting hole is opened at the same position of the FPC501 and the connecting plate 5. The connecting columns 201 at the four corners of the bottom of the bracket 2 pass through the connecting holes 502 on the FPC501 and the connecting plate 5 in turn to achieve a fixed connection between the three. Then, the washer 6 and the magnet 7 are installed at the bottom of the connecting plate 5, and the magnet 7 is installed in the installation area in the middle of the upper end of the basin frame 3. The speaker is installed as a whole by means of the FPC 501. When in use, the electrical signal of the external circuit is transmitted to the FPC 501. The FPC 501 transmits the electrical signal to the voice coil 4. The voice coil 4 converts the input electrical signal into mechanical vibration. The vibration of the voice coil 4 drives the diaphragm to produce sound. Since the embedded grooves 401 on the left and right sides of the bottom of the voice coil 4 are matched with the connecting plate 5, the voice coil 4 can be prevented from loosening or displacement during operation, which helps to reduce sound distortion and noise, so that the speaker can restore the sound signal more accurately. The magnet 7 provides a magnetic field, which interacts with the voice coil 4, the washer 6 and other components to form a complete magnetic circuit system. The washer 6 plays a magnetic conductive role, guides the magnetic field, enhances the magnetic flux of the speaker, and improves the sensitivity and output power of the speaker.
