Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a vehicle-mounted tweeter. Background Technology

[0002] A tweeter is an audio device specifically designed to produce high-frequency sounds. It works by using an audio signal to drive a voice coil, which generates a magnetic field that causes the diaphragm to vibrate, ultimately producing high-frequency sounds.

[0003] Most existing automotive tweeter diaphragms employ a single-fold surround and hard dome design. While the hard dome effectively suppresses split vibrations in the mid-to-low frequencies, at high frequencies, the single-fold surround at the edges may not keep up with the vibrations of the central dome, leading to split vibrations in the diaphragm and impaired high-frequency response. Furthermore, split vibrations in the high-frequency range can generate resonance peaks, resulting in an uneven frequency response curve and affecting the smoothness of high frequencies, thus limiting the high-frequency extension of the automotive tweeter.

[0004] Therefore, there is an urgent need to design a vehicle tweeter that can effectively suppress high-frequency segmentation vibration and has good high-frequency extension. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle-mounted tweeter that can effectively suppress high-frequency split vibration, while also providing wider high-frequency extension, cleaner treble, and higher fidelity.

[0013] The voice coil can drive the diaphragm to vibrate, and the inner and outer folded rings can simultaneously drive the diaphragm to vibrate and produce sound.

[0014] Optionally, a limiting structure is provided inside the basin frame, the limiting structure being used to limit the movement of the magnetic circuit assembly.

[0015] Optionally, the vehicle-mounted tweeter further includes a wire, the voice coil is connected to the AC power source via the wire, and the frame is provided with a clearance groove, in which the wire can be accommodated.

[0016] Optionally, the vehicle-mounted tweeter also includes a mask that covers the diaphragm and is connected to the frame, the mask being used to protect the diaphragm.

[0017] Optionally, one of the face mask and the basin stand is provided with a first slot, and the other is provided with a first protrusion, the first protrusion being able to engage in the first slot.

[0018] Optionally, the vehicle-mounted tweeter also includes a rear cover disposed below and connected to the frame.

[0022] The beneficial effects of this utility model are:

[0023] The vehicle-mounted tweeter provided by this utility model features an inner folded ring at the top of the hard dome, with one end of the inner bracket fixedly connected to the inner folded ring and the other end fixedly connected to the magnetic circuit assembly. The outer folded ring is fixedly connected to the frame, allowing both the inner and outer folded rings to simultaneously drive the diaphragm to vibrate and produce sound.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] like Figures 1 to 3 As shown, this embodiment provides a vehicle-mounted tweeter, which includes a diaphragm 2, a voice coil 3, an inner support 4, a frame 5, and a magnetic circuit assembly 6. The diaphragm 2 includes an inner folded ring 21, an outer folded ring 22, and a diaphragm 23, with the diaphragm 23 disposed between the inner folded ring 21 and the outer folded ring 22. The voice coil 3 abuts against the diaphragm 2 and can be connected to an external AC power source. The magnetic circuit assembly 6 is disposed at the voice coil 3 and provides a magnetic field for the voice coil 3. The inner support 4 is disposed between the diaphragm 2 and the magnetic circuit assembly 6, with one end fixedly connected to the inner folded ring 21 and the other end fixedly connected to the magnetic circuit assembly 6. The voice coil 3, the inner support 4, and the magnetic circuit assembly 6 are all disposed within the frame 5, and the outer folded ring 22 is fixedly connected to the frame 5. The voice coil 3 can drive the diaphragm 2 to vibrate, and the inner folded ring 21 and the outer folded ring 22 can simultaneously drive the diaphragm 23 to vibrate and produce sound.

[0051] By setting the dome of the hard dome as an inner folded ring 21, and fixing one end of the inner bracket 4 to the inner folded ring 21 and the other end to the magnetic circuit assembly 6, and fixing the outer folded ring 22 to the frame 5, the inner folded ring 21 and the outer folded ring 22 can simultaneously drive the diaphragm 23 to vibrate and produce sound. Compared with the diaphragm structure of a single folded ring plus a hard dome in the prior art, the diaphragm structure provided in this embodiment can effectively suppress high-frequency split vibration, improve high-frequency extension, and make the high frequencies of the vehicle tweeter cleaner and more accurate.

[0052] like Figure 4 and Figure 7 As shown, both the inner folded ring 21 and the outer folded ring 22 are ring structures with a semi-circular cross-section. The part connecting the diaphragm 23 to the inner folded ring 21 is roughly a spherical cap structure, with the top part replaced by the inner folded ring 21. The circular end on the lower side of the spherical cap is folded upwards and connected to the outer folded ring 22. An overlapping structure 24 is also provided on the outer side of the outer folded ring 22. The inner folded ring 21 and the outer folded ring 22 are both structural components made of silk film material, while the diaphragm 23 is a structural component made of aluminum-magnesium alloy material.

[0053] like Figure 1 and Figure 4As shown, the voice coil 3 is a ring-shaped plate structure. The voice coil 3 is located on the lower side of the diaphragm 2 and abuts against the folded part of the diaphragm 23. Thus, when the voice coil 3 vibrates back and forth, it can drive the diaphragm 2 to vibrate back and forth to generate sound waves. Two wires 8 are connected to the voice coil 3, and the voice coil 3 is connected to an external AC power source through the wires 8.

[0054] like Figure 1 and Figure 4 As shown, the magnetic circuit assembly 6 includes a magnetic sheet 61, a magnet 62, and a magnetic cup 63. The magnetic sheet 61, magnet 62, and magnetic cup 63 are all cylindrical structures. The upper cylindrical surface of the magnetic cup 63 is recessed inward to form a receiving groove 631. The magnetic sheet 61 and magnet 62 are both disposed within the receiving groove 631, with the magnetic sheet 61 positioned above the magnet 62. The magnetic circuit assembly 6 is positioned below the diaphragm 2 and has a gap with it. The voice coil 3 is disposed between the diaphragm 2 and the magnetic circuit assembly 6. Part of the voice coil 3 is disposed within the receiving groove 631 and located outside the magnetic sheet 61, while the other part is disposed outside the receiving groove 631 and located in the gap between the magnetic circuit assembly 6 and the diaphragm 2. The magnetic circuit assembly 6 can provide a magnetic field for the voice coil 3. When the alternating current passes through the voice coil 3, the voice coil 3 is subjected to the Lorentz force in the magnetic field generated by the magnetic circuit assembly 6. Under the action of the Lorentz force, the voice coil 3 can move up and down. At the same time, due to the repeated changes in the direction of the alternating current, the direction of the Lorentz force on the voice coil 3 also changes repeatedly, which causes the voice coil 3 to vibrate repeatedly.

[0055] like Figure 1 and Figure 4 As shown, the inner support 4 has a hat-shaped structure, with the top of the hat facing the inner folded ring 21. The inner support 4 is disposed between the diaphragm 2 and the magnetic conductive sheet 61, and is located within the annular ring of the voice coil 3. The top portion of the inner support 4 is fixedly connected to the inner folded ring 21, and the brim portion of the inner support 4 is fixedly connected to the magnetic conductive sheet 61. Optionally, in this embodiment, the inner support 4 is fixedly bonded to both the inner folded ring 21 and the magnetic conductive sheet 61 using adhesive. The adhesive easily flows into the gaps for bonding, making the operation convenient and providing a good bonding effect.

[0056] like Figure 1 , Figure 4 and Figure 6 As shown, the basket frame 5 is generally a ring-shaped shell structure. The voice coil 3, inner support 4, and magnetic circuit assembly 6 are all disposed inside the basket frame 5. The outer folding ring 22 is fixedly connected to the basket frame 5 through the overlapping structure 24 on its outer side. Optionally, in this embodiment, the overlapping structure 24 and the basket frame 5 are fixedly bonded together with adhesive. The adhesive can easily flow into the gaps for bonding, which is convenient to operate and has a good bonding effect.

[0057] Furthermore, in order to limit the movement of the magnetic circuit assembly 6 within the basin holder 5, such as... Figure 4 , Figure 6 and Figure 8As shown, a limiting structure 52 is provided inside the basin frame 5 to limit the magnetic circuit assembly 6.

[0058] Optionally, in this embodiment, the limiting structure 52 is a limiting buckle, and multiple buckles are spaced apart on the inner ring wall of the basin frame 5. The limiting buckle includes a vertical portion and a horizontal portion. The vertical portion is mounted on the inner ring wall of the basin frame 5, and the horizontal portion is located at the upper end of the vertical portion and protrudes away from the inner ring wall. The horizontal portion of the limiting buckle is located above and overlaps the magnetic cup 63, thereby restricting the upward movement of the magnetic circuit assembly 6. It is understood that in some other embodiments, the limiting structure 52 may also adopt other types of structures, such as limiting rings, which are not limited here.

[0059] like Figure 6 As shown, a clearance groove 54 is also provided on the outer ring wall of the frame 5, and the wire 8 can be accommodated in the clearance groove 54. By providing a clearance groove 54 on the frame 5, not only is a passage provided for the wire 8, but the wire 8 is also hidden in the clearance groove 54, which can optimize the overall structure of the vehicle tweeter and avoid the wire 8 occupying extra space, thus making the overall structure of the vehicle tweeter larger.

[0060] like Figure 1 and Figure 4 As shown, the vehicle-mounted tweeter also includes a rear cover 7, which is located below and connected to the frame 5. The rear cover 7 supports the magnetic circuit assembly 6 inside the frame 5. Specifically, the rear cover 7 includes a plate-shaped support portion 71, which supports the magnetic circuit assembly 6 inside the frame 5. The support portion 71 and the limiting structure 52 respectively limit the lower and upper sides of the magnetic circuit assembly 6, thereby fixing the magnetic circuit assembly 6 inside the frame 5. Further, as... Figure 4 As shown, the lower opening end of the frame 5 is also provided with a clearance step 56, and the support part 71 can be set on the clearance step 56, thereby reducing the overall height of the vehicle tweeter.

[0061] Furthermore, such as Figure 6 , Figure 8 , Figure 9 As shown, a conductor 73 is provided on the rear cover 7, and a clamping block 53 is provided on the frame 5. The clamping block 53 has a clamping groove 531. The conductor 73 passes through the clamping groove 531 and forms a clamping space. One end of the wire 8 is electrically connected to the voice coil 3, and the other end is clamped in the clamping space and electrically connected to the conductor 73. The conductor 73 is connected to an external AC power source. Compared with connecting an external AC power source through the wire 8, connecting an external AC power source through the conductor 73 is simpler and more convenient.

[0062] Furthermore, such as Figure 10As shown, the rear cover 7 also has a plug-in interface 721, into which an AC power connector can be inserted and electrically connected to the conductor 73. This design further facilitates the connection between the vehicle-mounted tweeter and an external power source. Specifically, the rear cover 7 also includes a block-shaped plug-in portion 72, with a support portion 71 positioned on the upper side of the plug-in portion 72. Figure 10 As shown, the insertion interface 721 is provided on the insertion portion 72. As... Figure 9 , Figure 10 and Figure 11 As shown, conductor 73 is disposed inside the rear cover 7, with one end of conductor 73 extending from the support 71 for electrical connection with wire 8, and the other end extending into the plug interface 721 for electrical connection with AC power plug.

[0063] Optionally, to achieve the connection between the back cover 7 and the basin stand 5, such as Figure 6 , Figure 8 and Figure 9 As shown, in this embodiment, the basin frame 5 is provided with a second slot 55, and the support part 71 of the rear cover 7 is provided with a second protrusion 711, which can be engaged in the second slot 55. The connection between the rear cover 7 and the basin frame 5 is achieved through the engaging structure, which is not only simple in structure but also facilitates the assembly and disassembly of the rear cover 7 and the basin frame 5.

[0064] Of course, it is understood that in some other embodiments, a second latching protrusion 711 may be provided on the basin frame 5 and a second latching groove 55 may be provided on the rear cover 7, which can achieve the same effect, and no limitation is made here.

[0065] like Figure 1 , Figure 2 and Figure 4 As shown, the vehicle-mounted tweeter also includes a cover 1, which is positioned above the diaphragm 2 and connected to the frame 5. The cover 1 protects the diaphragm 2. Specifically, the cover 1 is roughly a shell structure, with a sound outlet 12 on its top cover, allowing the sound generated by the vibration of the diaphragm 2 to propagate outward through the sound outlet 12. The cover 1 is positioned above the diaphragm 2 and completely covers the outside of the frame 5. Through this arrangement, the cover 1 not only protects the diaphragm 2 and the frame 5 from external influences but also further reduces the overall height of the vehicle-mounted tweeter.

[0066] Optionally, to achieve the connection between the face mask 1 and the basin stand 5, such as Figure 2 , Figure 5 and Figure 6As shown, in this embodiment, the face mask 1 has a first slot 11, and the basin stand 5 has a first protrusion 51, which can be engaged in the first slot 11. The connection between the face mask 1 and the basin stand 5 is achieved through the engaging structure, which is not only simple in structure but also facilitates the assembly and disassembly of the face mask 1 and the basin stand 5.

[0067] Of course, it is understood that in some other embodiments, a first slot 11 may be provided on the basin frame 5 and a first protrusion 51 may be provided on the face mask 1, which can achieve the same effect, and no limitation is made here.

[0068] The vehicle-mounted tweeter provided in this embodiment features an inner folded ring 21 at the dome of the hard dome, with one end of the inner bracket 4 fixedly connected to the inner folded ring 21 and the other end fixedly connected to the magnetic circuit assembly 6. The outer folded ring 22 is fixedly connected to the frame 5. This allows both the inner and outer folded rings 21 and 22 to simultaneously drive the diaphragm 23 to vibrate and produce sound. Compared to the existing diaphragm structure with a single folded ring and hard dome, the diaphragm structure provided in this embodiment effectively suppresses high-frequency breakup vibrations, improves high-frequency extension, and results in cleaner, more accurate high-frequency reproduction of the vehicle-mounted tweeter.

[0069] also, Figure 12 The stress variation curve of the diaphragm 2 cross section under a voltage of 2V in this embodiment is shown, represented by a solid line; Figure 12 The diagram also shows the diaphragm cross-sectional stress variation curve of the proposed technical solution (i.e., single-fold ring with hardened dome design) under the same conditions, represented by a dashed line. Compared with the proposed solution in the background art, it is obvious that the cross-sectional stress variation curve of the technical solution in this embodiment is smoother, that is, the high-frequency segmentation vibration is weaker, which in turn enables a wider high-frequency extension and a better high-frequency response.

[0070] Figure 13 The stress variation curve of the diaphragm 2 cross section under a voltage of 8.9V in this embodiment is shown, represented by a solid line; Figure 13 The diagram also shows the diaphragm cross-sectional stress variation curve of the proposed technical solution (i.e., single-fold ring with hardened dome design) under the same conditions, represented by a dashed line. Compared with the proposed solution in the background art, it is obvious that the cross-sectional stress variation curve of the technical solution in this embodiment is smoother, that is, the high-frequency segmentation vibration is weaker, which in turn enables a wider high-frequency extension and a better high-frequency response.

[0071] Figure 14 The frequency response curve for this embodiment at 2V is shown, represented by a solid line; Figure 14The frequency response curve of the proposed technical solution (i.e., single-fold surround with hard dome design) under the same conditions is also shown, represented by a dashed line. Compared with the proposed solution in the background art, it is obvious that the frequency response curve of the technical solution in this embodiment is higher in the high-frequency range (i.e., after 2kHz), meaning that the high-frequency response of the vehicle tweeter in this embodiment is better.

[0072] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
