Description

Technical Field

[0001] This invention relates to the field of acoustic device technology, and in particular to a novel loudspeaker. Background Technology

[0002] In today's society, mobile devices such as smartphones and tablets enrich people's lives, and electroacoustic converters play an indispensable role as audio devices. As consumers' demands for sound quality and loudness increase, the corresponding requirements for speaker performance, such as amplitude, also rise, especially for bass quality and loudness. At the same time, to ensure overall thinness, speakers must be made increasingly thinner, which limits speaker amplitude. Amplitude is a crucial determinant of bass quality and loudness; limited amplitude significantly restricts the improvement of bass quality and loudness, making it difficult to meet the required levels. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a novel loudspeaker that ensures a thin and light design while having a large amplitude.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a novel loudspeaker, comprising:

[0005] Diaphragm;

[0006] A basin frame, on which the diaphragm is mounted;

[0007] A voice coil assembly, the voice coil assembly including a voice coil, the voice coil being installed inside the frame;

[0008] A magnetic circuit assembly, the magnetic circuit assembly including a magnet, the magnet being movably disposed inside the voice coil;

[0009] A support rod is provided with a pivot in the middle of the support rod. The support rod is rotatably mounted on the basin frame through the pivot. One end of the support rod is connected to the magnet, and the other end of the support rod is provided with a supporting part. The supporting part abuts against the diaphragm. The horizontal distance from the supporting part to the pivot is greater than the horizontal distance from the center of gravity of the magnet to the pivot.

[0010] The beneficial effects of this invention are as follows: This novel loudspeaker has a novel structure and strong practicality. By utilizing the lever principle, the small vibration amplitude of the magnetic circuit component is amplified by the support rod and applied to the diaphragm, thereby increasing the diaphragm amplitude and effectively improving the bass sound quality and loudness of the loudspeaker. While increasing the vibration amplitude of the diaphragm, it is not necessary to significantly increase the vibration amplitude of the magnetic circuit component, which is conducive to controlling the size of the loudspeaker and realizing the thinning of electronic products.

[0022] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to Figures 1 to 4 A novel loudspeaker includes a diaphragm 1, a frame 2, a voice coil assembly, a magnetic circuit assembly 4, and a support rod 5. The diaphragm 1 is mounted on the frame 2. The voice coil assembly includes a voice coil 3, which is installed inside the frame 2. The magnetic circuit assembly 4 includes a magnet 41, which is movably disposed inside the voice coil 3. The support rod 5 has a pivot 6 in the middle, and the support rod 5 is rotatably mounted on the frame 2 via the pivot 6. One end of the support rod 5 is connected to the magnet 41, and the other end of the support rod 5 has a supporting part 51 that abuts against the diaphragm 1. The horizontal distance from the supporting part 51 to the pivot 6 is greater than the horizontal distance from the center of gravity of the magnet 41 to the pivot 6.

[0024] As can be seen from the above description, the beneficial effects of the present invention are as follows: The novel speaker structure is novel and highly practical. By utilizing the lever principle, the small vibration amplitude of the magnetic circuit component is amplified by the support rod and applied to the diaphragm, thereby increasing the diaphragm amplitude and effectively improving the bass sound quality and loudness of the speaker. While increasing the vibration amplitude of the diaphragm, it is not necessary to significantly increase the vibration amplitude of the magnetic circuit component, which is beneficial to controlling the size of the speaker and realizing the thinning of electronic products.

[0025] Furthermore, the support rod 5 is parallel to the diaphragm 1, and the abutment part 51 is a top rod, which is arranged perpendicular to the support rod 5.

[0026] As described above, the parallel arrangement of the support rods ensures that the support rods can amplify the amplitude of the vibration of the magnetic circuit assembly to the maximum extent, which is beneficial to improving the acoustic performance of the loudspeaker.

[0027] Furthermore, the top rod abutting the diaphragm 1 is provided with a supporting head 511.

[0028] As can be seen from the above description, the support head can prevent the push rod from damaging or puncturing the surface of the diaphragm when pushing the diaphragm to vibrate.

[0029] Furthermore, the supporting portion 51 abuts against the middle portion of the diaphragm 1.

[0030] As can be seen from the above description, the supporting part abutting against the middle of the diaphragm makes it easier for the diaphragm to vibrate, and at the same time can ensure that the vibration generated by the diaphragm is more uniform.

[0031] Furthermore, the diaphragm 1 has a center patch 11 at its bottom, and the supporting part 51 abuts against the center patch 11.

[0032] As can be seen from the above description, compared with the diaphragm, the middle patch has higher structural strength. When the supporting part pushes the diaphragm to vibrate, the middle patch can effectively protect the diaphragm from being damaged by the supporting part. At the same time, the supporting part abuts against the middle patch, which helps to make the vibration of the diaphragm more uniform.

[0033] Furthermore, the center patch 11 is provided with a spring piece 111, one end of which is connected to the center patch 11, and the other end of which abuts against the support rod 5 near the abutting part 51.

[0034] As described above, the spring is used to reset the support rod, so that when the voice coil is not energized, the support rod can always remain parallel to the diaphragm.

[0035] Furthermore, the magnetic circuit assembly 4 includes two stacked magnets 41, with a pole piece 52 sandwiched between the two magnets 41, and the pole piece 52 is connected to the support rod 5.

[0036] As described above, the use of two magnets in each magnetic circuit assembly can effectively increase the BL value of the speaker, thereby significantly improving the acoustic performance of the speaker.

[0037] Furthermore, the voice coil assembly includes two voice coils 3 arranged side by side, and the voice coils 3 are arranged in a one-to-one correspondence with the magnets 41.

[0038] As described above, setting two voice coils in each set of voice coil components can effectively increase the BL value of the loudspeaker, thereby further improving the acoustic performance of the loudspeaker.

[0039] Furthermore, the support rod 5 is Y-shaped.

[0040] As described above, the Y-shaped support rod can be equipped with two abutment parts at the same time, thereby pushing the diaphragm more stably and evenly.

[0041] Furthermore, there are two support rods 5, which are arranged symmetrically.

[0042] As can be seen from the above description, the symmetrical arrangement of the two support rods can make the thrust from the supporting part on the diaphragm more uniform.

[0043] Example 1

[0044] Please refer to Figures 1 to 4 Embodiment 1 of the present invention is: a novel speaker, which is applied to electronic devices such as mobile phones, speakers, smartwatches, tablet computers, and laptops.

[0045] The novel loudspeaker includes a diaphragm 1, a frame 2, a voice coil assembly, a magnetic circuit assembly 4, and a support rod 5. The diaphragm 1 includes an inner fixing part, a surround part, and an outer fixing part connected sequentially from the inside out. The diaphragm 1 is mounted on the frame 2 via the outer fixing part. The voice coil assembly includes a voice coil 3, which is installed inside the frame 2. The magnetic circuit assembly 4 includes a magnet 41, which is movably disposed inside the voice coil 3. The support rod 5 has a rotating shaft 6 in its middle, allowing it to be rotatably mounted on the frame 2 via the rotating shaft 6. One end of the support rod 5 is connected to the magnet 41, and the other end has a supporting part 51 that abuts against... On the diaphragm 1, the horizontal distance from the supporting part 51 to the rotating shaft 6 is greater than the horizontal distance from the center of gravity of the magnet 41 to the rotating shaft 6. In this embodiment, the magnet 41 is at least partially located inside the voice coil 3. The supporting part 51 abuts against the inner fixing part of the diaphragm 1. The support rod 5 is made of a material with high rigidity. The support rod 5 is an integral structure formed by one-piece machining. The support rod 5 has a through hole in the middle. The rotating shaft 6 passes through the through hole. The two ends of the rotating shaft 6 are respectively connected to the opposite side walls of the frame 2. The rotating shaft 6 is detachably connected to the frame 2. In other embodiments, the support rod 5 and the rotating shaft 6 can also be an integral structure formed by one-piece machining.

[0046] When the voice coil 3 is energized, the input electrical signal passing through the voice coil 3 will create an alternating magnetic field around the voice coil 3. The magnetic circuit assembly 4 located inside the voice coil 3 will vibrate up and down under the influence of the alternating magnetic field. When the magnetic circuit assembly 4 vibrates, it will drive the support rod 5 to swing around the rotating shaft 6. At this time, the other end of the support rod 5 will drive the abutment part 51 to swing up and down and push the diaphragm 1, causing the diaphragm 1 to vibrate. Since the horizontal distance from the abutment part 51 to the rotating shaft 6 is greater than the horizontal distance from the center of gravity of the magnet 41 to the rotating shaft 6, the support rod 5 will transmit the vibration generated by the magnet 41 to the diaphragm 1, and at the same time, amplify the original vibration amplitude of the magnet 41 and transmit it to the diaphragm 1. Compared with the magnet 41 directly driving the diaphragm 1 to vibrate, this solution can effectively increase the amplitude of the diaphragm 1 without significantly increasing the vibration amplitude of the magnetic circuit assembly 4.

[0047] Please refer to Figure 2 and Figure 3There are two support rods 5, which are symmetrically arranged. In this embodiment, the two abutting parts 51 of the two support rods 5 are arranged close to each other and abut against the middle of the diaphragm 1. There are two voice coil assemblies, which are respectively arranged on both sides of the frame 2. There are two magnetic circuit assemblies 4, which are respectively installed on the two support rods 5. The magnetic circuit assemblies 4 and the voice coil assemblies are arranged in a one-to-one correspondence. Preferably, all the voice coils 3 of the two voice coil assemblies are connected in parallel, and the vibration phase and amplitude of the two magnetic circuit assemblies 4 are consistent.

[0048] Optionally, the support rod 5 is parallel to the diaphragm 1, and the abutment part 51 is a top rod. The top rod is arranged perpendicular to the support rod 5. In this embodiment, one end of the top rod is connected to the end of the support rod 5, and the other end of the top rod abuts against the diaphragm 1. The abutment part 51 and the support rod 5 are integrally formed. In other embodiments, the abutment part 51 and the support rod 5 can also be separately formed and connected by fasteners or adhesives.

[0049] To prevent the supporting part 51 from damaging the diaphragm 1 when pushing it, optionally, a supporting head 511 is provided at the point where the push rod abuts the diaphragm 1. The supporting head 51 can increase the contact area between the push rod and the diaphragm 1, thereby preventing the push rod from scratching or even puncturing the surface of the diaphragm 1 during the long-term reciprocating pushing of the diaphragm 1, which would affect the acoustic performance of the speaker.

[0050] The diaphragm 1 has a center patch 11 at its bottom, and the abutting part 51 abuts against the center patch 11. The center patch 11 is disposed on the bottom surface of the inner fixing part of the diaphragm 1. Optionally, the connection between the center patch 11 and the inner fixing part can be hot pressing, injection molding or adhesive bonding. In this embodiment, the center patch 11 is connected to the inner fixing part by adhesive bonding, and the abutting part 51 abuts near the center line of the long side of the center patch 11.

[0051] Please refer to Figure 2 and Figure 4The center patch 11 is provided with a spring piece 111. One end of the spring piece 111 is connected to the center patch 11, and the other end of the spring piece 111 abuts against the support rod 5 near the abutting part 51. Optionally, the spring piece 111 and the center patch 11 are integrally formed. In this embodiment, the spring piece 111 is used to reset the support rod 5, so that when the voice coil 3 is not energized, the support rod 5 always remains parallel to the diaphragm 1. This avoids the support rod 5 from tilting upwards at the end where the abutting part 51 is provided due to the weight of the magnetic circuit assembly 4, which would cause the abutting part 51 to push the diaphragm 1 upwards for a long time, eventually leading to damage or irreversible deformation of the diaphragm 1, thereby affecting the acoustic performance of the new loudspeaker.

[0052] In this embodiment, a supporting piece 112 is provided at the end of the spring piece 111 away from the center patch 11. The supporting piece 112 is parallel to the diaphragm 1 and is arranged along the length direction of the support rod 5. The surface of the supporting piece 112 abuts against the support rod 5 near the supporting part 51. Preferably, the end face of the supporting piece 112 abuts against the supporting part 51. When the supporting part 5 pushes the diaphragm 1 to vibrate, the supporting piece 112 can disperse the thrust of the supporting part 51 on the diaphragm 1 along the spring piece 111, so that the force on the center patch 11 is more uniform, thereby making the vibration of the diaphragm 1 more uniform.

[0053] Please refer to Figure 2 The magnetic circuit assembly 4 includes two stacked magnets 41, with a pole piece 52 sandwiched between the two magnets 41. The pole piece 52 is connected to the support rod 5. In this embodiment, a center washer 42 is provided at the top of the magnet 41 above the pole piece 52, and a center washer 42 is provided at the bottom of the magnet 41 below the pole piece 52. Optionally, the magnet 41 and the center washer 42 are connected by adhesive, and the magnet 41 and the pole piece 52 are connected by adhesive.

[0054] Furthermore, the voice coil assembly includes two voice coils 3 arranged side by side, with each voice coil 3 corresponding to a magnet 41. In this embodiment, a fixed boss 21 is provided inside the frame 2, and the fixed boss 21 is arranged in a ring on the inner wall of the frame 2. The rotating shaft 6 is mounted on the fixed boss 21, and the two voice coils 3 are respectively arranged on the upper and lower sides of the fixed boss 21. The pole piece 52 is located between the two voice coils 3. In other embodiments, a magnet 41 may also be provided, with the middle part of the magnet 41 connected to the support rod 5. The two ends of the magnet 41 are respectively located inside the two voice coils 3. The top and bottom surfaces of the magnet 41 are respectively provided with the center washer 42.

[0055] Please refer to Figure 3The support rod 5 is Y-shaped. In this embodiment, the support rod 5 has two branches, and each branch end is provided with a top rod. The two top rods respectively abut against the two ends of the center line of the long side of the middle patch 11. The middle patch 11 is provided with four spring pieces 111. The four spring pieces 111 are symmetrically arranged, and the four spring pieces 111 correspond one-to-one with the four branches of the two support rods 5.

[0056] In summary, the novel loudspeaker provided by this invention features a novel structure and strong practicality. Utilizing the lever principle, it amplifies the relatively small vibration amplitude of the magnetic circuit assembly via a support rod and applies it to the diaphragm, thereby increasing the diaphragm's amplitude and effectively improving the loudspeaker's bass quality and loudness. While increasing the diaphragm's vibration amplitude, it does not require a significant increase in the vibration amplitude of the magnetic circuit assembly, which is beneficial for controlling the loudspeaker's size and achieving a thinner and lighter electronic product. The parallel arrangement of the support rod ensures that it can amplify the vibration amplitude of the magnetic circuit assembly to the maximum extent, which is beneficial for improving... To enhance the acoustic performance of the loudspeaker, a support head is provided on the support part, which rests against the center plate with higher structural strength. This effectively protects the diaphragm from damage by the support part and promotes more uniform diaphragm vibration. A spring is provided on the center plate for the support rod to return to its original position, so that the support rod can always remain parallel to the diaphragm when the voice coil is not energized, avoiding damage or deformation of the diaphragm and thus affecting the acoustic performance of the loudspeaker. The use of a matching voice coil and magnet can effectively increase the BL value of the loudspeaker, thereby further improving the acoustic performance of the loudspeaker.
