Description

Technical Field

[0001] The utility model relates to the technical field of sound - producing devices, in particular to a diaphragm suspension structure and a sound - producing device. Background Art

[0002] With the development of technology, a planar diaphragm loudspeaker has become increasingly popular among users because it has no cabinet resonance and a more natural sound propagation. Its principle is to apply an audio current to a conductive film placed in a magnetic field. When the energized conductive film passes through the magnetic field, it will be affected by the magnetic force. By changing the direction and magnitude of the audio current, the direction and magnitude of the magnetic force on the conductive film also change, so that the conductive film vibrates under the force and emits sound. However, although conventional planar diaphragm loudspeakers can perfectly reproduce high - frequency and ultra - high - frequency signals, and have unique timbre and sound quality, they may also face some challenges, such as limitations in low - frequency response. Therefore, when used, conventional planar diaphragm loudspeakers cannot perfectly cover the high, middle, and low audio spectra, thus failing to meet the user's needs. Summary of the Utility Model

[0041] The diaphragm has two opposite sides. The low-frequency sound waves emitted by the diaphragm are more likely to diffract around the edge of the diaphragm. The sound waves on one side will diffract towards the other side. The phase difference between the sound waves on the front and back sides is 180 degrees. Therefore, when the sound waves meet at the two opposite sides, cancellation will occur. The directivity of the high-frequency sound is better, and the high-frequency sound waves are not likely to diffract. Therefore, most planar diaphragm speakers can emit good high-frequency sound quality, but the emitted low-frequency sound quality is not good.

[0042] In view of this, the inventor considered blocking the diffraction of the low-frequency sound at the edge of the diaphragm, reducing the mutual cancellation of the low-frequency sound on the opposite sides of the diaphragm, thereby increasing the low-frequency effect of the sound-emitting device. However, in this case, it is required that there is an entity blocking the transmission of the low-frequency sound waves at the edge where the low-frequency sound diffracts along the diaphragm, and the length of the entity cannot be too short, otherwise it cannot effectively block the propagation of the low-frequency sound waves. Here, it can be understood that the height of the entity should be equal to or higher than the height of the diaphragm. Then, in many scenarios with space limitations, this solution is subject to certain limitations. The larger the area of the entity blocking the low-frequency diffraction, the larger the volume of the diaphragm suspension structure will be, resulting in a larger volume of the sound-emitting device and inconvenient use.

[0043] Based on this, the inventor of the present utility model designed the solutions of the embodiments provided in this application, setting one side edge of the diaphragm along the length direction as the fixed side edge and the other side edge as the free side edge. The fixed side edge is in a state of supporting the entire diaphragm, and there is an entity capable of blocking the sound waves on the side of the fixed side edge away from the free side edge. The low-frequency sound emitted by the fixed side edge is blocked by the entity and cannot diffract, thereby avoiding the front-back cancellation of some low-frequency sound waves and enhancing the low-frequency effect. In addition, the fixed side edge can be set on the wall or any entity with a certain length, thereby using the structure at the installation position to further reduce the volume of the diaphragm suspension structure. The diaphragm suspension structure can not only compensate for the low-frequency sound but also provide stable support for the diaphragm.

[0048] Embodiment 1:

[0049] Before a detailed description of the diaphragm suspension structure 1 of the embodiments of this application, a brief introduction to the sound generation principle of the diaphragm 10 is given first, so that readers can better understand the solutions of the embodiments of this application.

[0050] The magnet has an S pole (South Pole) and an N pole (North Pole). Two magnets are arranged with the same poles facing each other. Please refer to Figure 1 , the magnetic induction lines will be affected by the magnetic poles of the other party and tend to move away from the magnetic poles of the other party, resulting in the magnetic field direction at the opposing gap between the two magnets with the same poles facing each other gradually tending to be perpendicular to the outgoing direction, that is, parallel to the opposing magnetic pole surfaces. Then, please refer to Figure 2 , multiple pairs of magnets with the same poles facing each other are arranged at intervals, and the magnetic poles of adjacent pairs of opposing magnets are opposite. Then, a stable and relatively strong magnetic field will be generated at the opposing gap between adjacent pairs of magnets with the same poles facing each other. The diaphragm 10 is arranged at the opposing gap. The diaphragm 10 has a conductive circuit 13. When there is current passing through the conductive circuit 13, the conductive circuit 13 will be vibrated by the magnetic field, thereby driving the diaphragm 10 to vibrate and generate sound.

[0051] It can be understood that sound has high-frequency sound waves and low-frequency sound waves. Among them, the high-frequency sound waves have short wavelengths, strong directivity, and weak diffraction ability; while the low-frequency sound waves have long wavelengths and are prone to diffraction. Since the phase difference of the sound waves on the front and back sides is 180 degrees, the sound waves diffracted in front of and behind the diaphragm will cancel each other out when they meet at the edge of the diaphragm. Therefore, if relatively light suspension ribbons or thin wires are used to support the edge of the diaphragm on both long sides of the diaphragm 10, making the edge of the diaphragm 10 in an open state, the situation of low-frequency diffracted sound waves being cancelled will inevitably occur, resulting in poor bass sound quality of the speaker.

[0052] This embodiment provides a diaphragm suspension structure 1, which can avoid the low-frequency diffraction of one side of the diaphragm without affecting the vibration and sound generation of the diaphragm, thereby improving the bass sound quality of the speaker to solve the above problems.

[0053] Specifically, as Figure 3 shown, the diaphragm suspension structure 1 provided in this embodiment includes a diaphragm 10, a fixing component 20, and a plurality of magnet groups 30 (not shown in the figure) located on the fixing component 20. The magnet group 30 includes two magnets 31 with opposite poles facing each other, so as to generate a stable magnetic field in the opposing gap. The conductive circuit 13 on the diaphragm 10 is located in the magnetic field. When an electric current passes through, the conductive circuit is forced to drive the diaphragm to vibrate and generate sound. Along the short side direction of the diaphragm 10, the diaphragm 10 has opposite free sides 12 and fixed sides 11. The fixed side 11 can be directly set on the entity or set on the fixing component 20. Whether the fixed side 11 is directly set on the entity or set on the fixing component 20, there should be no gap between the fixed side 11 and the entity to prevent low-frequency sound wave diffraction. When the fixed side 11 is set on the fixing component 20, there will be two situations. The first situation is that the entire edge of the fixed side 11 is fixedly set on the fixing component 20, the fixing component 20 is in contact with the entity, and the fixed side 11 is fixedly set with the fixing component 20, and there is no relative displacement between the fixed side 11 and the fixing component 20, so as to ensure that there is no gap between the fixed side 11 and the entity. The second situation is that the fixed side 11 is softly fixed with the fixing component 20 and can have relative displacement. However, when the fixed side 11 has relative displacement with respect to the fixing component 20, the edge of the fixed side 11 always remains in contact with the fixing component 20, ensuring that low-frequency sound waves will not diffract around the edge of the fixed side 11 without interfering with the vibration and sound generation of the diaphragm.

[0054] The application scope of the diaphragm suspension structure 1 of the embodiment of the present application includes but is not limited to desktop audio, home theater audio, large conference room audio, both sides of the screen, etc. In order to ensure a good auditory system, the diaphragm suspension structure 1 can be provided on both sides of the entity. When applied to desktop audio, the entity can be a component related to the power amplifier circuit, and the diaphragm suspension structure can be produced together with the desktop audio and directly installed on both sides of the entity before leaving the factory; when applied to a home theater, the diaphragm suspension structure 1 can be located on both sides of the suspended TV screen, or the walls on both sides of the projection screen can be provided with the diaphragm suspension structure 1, where the walls on both sides of the projection screen are the walls perpendicular to the wall where the projection screen is located, and the diaphragm 10 is parallel to the wall where the projection screen is located, so that a more natural sound without box resonance can be enjoyed during the viewing process, and the viewing experience can be improved; when applied to a large conference room, the diaphragm suspension structure 1 can be provided on the walls on the left and right sides of the frontmost display screen, or the diaphragm suspension structure 1 can be provided on the walls on both sides perpendicular to the display screen. When applied to a screen, the left and right sides of the screen are provided with a diaphragm suspension structure 1. The screen can be located in a Zen room, tea room, chess room, etc. At this time, some soothing light music can be played to relax the mood. At the same time, people can have a more private space when playing chess, drinking tea, and discussing business in front of the screen; the two sides of the picture frame of the display painting can also be provided with a diaphragm suspension structure 1. When people are in front of the display painting to observe, they are in the best listening area and can hear the explanation information of the display painting; the wall surfaces on both sides of a protruding wall can also be provided with a diaphragm suspension structure 1, and the front of the wall can be provided with display elements. Etc., as long as the installation of the diaphragm suspension structure 1 can be met and there is no gap between the edge of the diaphragm 10 and the entity.

[0055] In some specific embodiments of the present application, Figures 4a to 4b The structural diagram of the diaphragm suspension structure 1 is shown to provide a detailed description of how to fix the diaphragm when the diaphragm suspension structure 1 is required on both sides of the entity such as a screen or a television.

[0056] The fixing assembly 20 includes a plurality of stacked fixing frames 21, and the fixing frames 21 have two opposite sides, one side is a fixing side 221, and the other side is a diaphragm mounting side 222, wherein a clamping groove is provided on the fixing side 221, and the side edge of the entity is accommodated in the clamping groove, and a plurality of transparent threaded holes are provided at intervals on the two side walls of the clamping groove, and the wing bolts are screwed into the threaded holes and pass through the threaded holes to abut against the front side edge of the entity, thereby fixing the fixing assembly 20 on the side edge of the entity. A handle that can be screwed by the operator is provided at the limiting head of the wing-shaped bolt, so that the operator can operate the installation and removal of the fixing frame conveniently.

[0057] In some embodiments of the present application, Figure 4aAs shown, a plurality of fixing brackets 21 are stacked in sequence in the height direction to form a fixing assembly. In some other embodiments, such as Figure 4b the fixing bracket 21 shown, there are two fixing brackets 21, and one fixing bracket 21 is provided on each side of the diaphragm 10. As long as the support for the diaphragm and the opposing magnets can be achieved, no specific limitation is made in this embodiment.

[0058] A diaphragm mounting groove 223 is provided on the diaphragm mounting side 222, and magnet mounting grooves with opposite openings are provided on the two side walls of the diaphragm mounting groove 223. Two magnets 31 with the same poles opposing are respectively arranged in the corresponding magnet mounting grooves, and a stable magnetic field is generated in a partial area within the diaphragm mounting groove 223, so that the conductive circuit 13 on the diaphragm 10 is located in the magnetic field. The fixing assembly 20 further includes a diaphragm clamp 22, and the diaphragm clamp 22 is arranged on the inner side wall of the diaphragm mounting groove 223 close to the fixed side. The edge of the fixed side 11 of the diaphragm 10 can be directly clamped on the diaphragm clamp 22 and abutted against the inner side surface of the diaphragm clamp 22, thereby avoiding the diffraction of low-frequency sound waves. Alternatively, a soft buffer abutting member 23 is provided on the clamping body of the diaphragm clamp 22, and the fixed side 11 is clamped between the two abutting members 23, which not only ensures the stable support of the diaphragm 10 but also ensures that the diaphragm 10 does not come into hard contact with the diaphragm clamp 22 to generate abnormal sounds, and further ensures that the diaphragm clamp 22 can be fitted with the diaphragm without gaps. The abutting member 23 can have a certain adhesiveness, so that the diaphragm 10 will not further separate from the abutting member 23. The abutting member 23 can be made of composite materials such as sponge, glue or EVA to reduce the noise generated by the hard contact between the diaphragm 10 and the diaphragm clamp 22. The free side 12 of the diaphragm 10 can be either not suspended or suspended with a lightweight elastic / viscoelastic rope to provide a certain restraint and restoring force. Interlayer glue can be provided between the side wall of the clamping groove and the side of the entity, and between the diaphragm clamp 22 and the inner side wall of the diaphragm mounting groove 223, which can not only prevent the generation of gaps but also play a buffering role for vibration impacts.

[0059] When the entity 2 is a wall, such as Figure 4aAs shown, the fixing component 20 includes a plurality of fixing frames 21 stacked in sequence in the height direction. At least a pair of magnet mounting grooves are provided on the fixing frame 21 to accommodate the opposed magnets 31. The opposed magnets 31 generate a stable magnetic field at the opposed gap, and the conductive circuit 13 on the diaphragm 10 is located at the opposed gap. In some embodiments of the present application, the fixing component 20 further includes a diaphragm clamp 22 located between two fixing frames 21. The diaphragm clamp 22 is in contact with the fixing frame 21. The fixing frame 21 abuts against the wall and is fixed to the wall. The fixing method can be screw fixing or embedding in the wall. This embodiment does not make specific limitations as long as the fixing frame 21 can be fixed to the wall. The fixing side 11 is clamped on the diaphragm clamp 22 and abuts against the inner side surface of the diaphragm clamp 22. Further, in some embodiments of the present application, the clamping body of the diaphragm clamp 22 is provided with an abutting member 23 having a certain buffering effect. The fixing side 11 is clamped between two abutting members 23, which not only ensures the stable support of the diaphragm 10, but also ensures that the diaphragm 10 will not have hard contact with the diaphragm clamp 22 to generate abnormal sounds. In addition, it ensures that the diaphragm clamp 22 can be in contact with the diaphragm without gaps. The abutting member 23 can have a certain viscosity so that the diaphragm 10 will not separate from the abutting member 23. The abutting member 23 can be made of composite materials such as sponge, glue or EVA. An interlayer glue or a soft composite material for preventing hard contact is provided between the fixing frame 21 and the wall, which can not only ensure that there is no gap between the fixing frame 21 and the wall, but also play a buffering role in preventing vibration impact between the fixing frame 21 and the wall.

[0060] In some embodiments of the present application, another feasible structure of the diaphragm suspension structure 1 includes a diaphragm 10 and a fixing component 20 that provides support for the diaphragm 10. Conductive circuits 13 are provided on both sides of the diaphragm 10 along the long side direction. The fixing component 20 is located in the center of the two conductive circuits 13. When current passes through the conductive circuits 13 on both sides, the two sides of the diaphragm 10 vibrate and emit sound simultaneously, which is used as the left and right channels. When the sound signals of the left and right channels are the same, the vibrations are the same, that is, the sound waves generated on the left and right sides are in the same phase and can be superimposed on each other without cancellation. Therefore, the bass effect is good. When the sound signals of the left and right channels are inconsistent, the diaphragms on the left and right sides increase the distance for the diffraction of the sound waves of each other, and the diffraction of the low frequency will also be reduced. This situation is applicable to small audio devices such as desktop speakers.

[0061] To meet the support requirements of the above small audio devices, in some embodiments of the present application, there are various feasible structures for the fixing component 20, such as Figures 5 to 6As shown, one of them is that the fixing component 20 includes a support rod 24, a base 25 located at the bottom end of the support rod 24 and abutting against the surface to be installed, and fixing frames 21 stacked in the height direction on both sides of the support rod 24. The fixing frames 21 are provided with magnet mounting grooves with opposite openings, and two magnets 31 with opposite poles facing each other are arranged in the magnet mounting grooves on the corresponding side, so that the conductive circuit 13 is located in a stable magnetic field. The base 25 can provide stable support for the support rod 24, so that the support rod 24 can be firmly located at the installation position to be installed, and thus the support rod 24 can support the fixing frames 21.

[0062] The diaphragm 10 is made of a hard material so that it can meet the overall support requirements when it is suspended unilaterally.

[0063] It can be understood that in order to prevent affecting the stability of the magnetic field, the entity and the fixing component are both made of non-magnetic materials.

[0064] Embodiment 2:

[0065] This embodiment provides a sound-emitting device, such as Figures 2 to 4b As shown, the sound-emitting device includes a central display piece and the diaphragm suspension structure 1 provided in Embodiment 1. The length direction of the central display piece is the left-right direction. The diaphragm suspension structure 1 is provided on at least one side of the central display piece in the left-right direction. It can be that there is only the diaphragm suspension structure 1 on one side or there are diaphragm suspension structures 1 on both sides. The central display piece can be a screen. When one side edge of the screen has the diaphragm suspension structure 1, since the screen has a certain length in the left-right direction, it can block the bass cancellation on one side when the unilateral diaphragm 10 emits sound. When there are diaphragm suspension structures 1 on both sides of the screen and the two side diaphragms 10 vibrate and emit sound, they respectively undertake the audio tasks of two channels. There is no problem of low-frequency cancellation on the side close to the middle for both side diaphragms. Since the audio device does not have an enclosed box, a good listening experience can be obtained in both the front and back directions perpendicular to the diaphragm. This screen can be applied to public places such as tea rooms, meditation rooms, or high-class restaurants. The central display piece can also be a display painting. The diaphragm suspension structures 1 are provided on both sides of the display painting in the left-right direction, making the display painting a sound-emitting display painting, and the sound emitted can be an explanation of the display painting. The central display piece can also be a screen, and the diaphragm suspension structure 1 is located on the walls on both sides of the screen and is perpendicular to the walls. This screen can be a movie screen, a corporate promotion screen, a conference screen, etc. The screen can be an electronic screen or a cloth projection screen. The specific reference of the central display piece in this embodiment is not specifically limited here.
