Detailed Description of the Embodiment

[0052] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0053] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "mount", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0054] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0055] In the description of the embodiments of the present application, "a plurality of" means two or more, unless otherwise specifically and precisely defined.

[0056] The terms "first", "second", "third", "fourth", etc. in the specification, claims and above-mentioned drawings of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0057] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0058] As described in the background art, the loudspeaker in the related art has problems such as more internal components, complex structure, and larger installation space required for the loudspeaker.

[0059] A loudspeaker is an electroacoustic device that converts an electrical signal into a sound signal. The loudspeaker includes a frame, a magnetic circuit assembly and a vibration assembly. The magnetic circuit assembly and the vibration assembly are housed in a space surrounded by the frame. The vibration assembly includes a voice coil and a diaphragm connected to the voice coil. When the voice coil receives an audio signal, it can vibrate under the action of the magnetic circuit assembly, and then drive the surrounding air to generate sound through the diaphragm, realizing the conversion of the electrical signal into a sound signal.

[0060] With the demand for better sound quality and acoustic performance, while satisfying the bass, the high-frequency response has also become an important part that cannot be ignored. In the related art, in order to improve the acoustic performance of the loudspeaker, the number of vibration assemblies is usually set to at least two to form at least one high-frequency sound generating unit and at least one low-frequency sound generating unit, and the high-frequency effect and the low-frequency effect are realized by controlling the audio signal, which is equivalent to adding a high-frequency sound generating unit on the basis of a conventional low-frequency sound generating unit.

[0061] However, the voice coils in the high-frequency sound generating unit and the low-frequency sound generating unit all need corresponding diaphragms to vibrate and generate sound, which results in a large number of components and a complex structure, leading to a large installation space required for the loudspeaker, and is not conducive to the lightweight and thin design of the loudspeaker.

[0062] Based on the above technical problems, an embodiment of the present application provides a vibration component and a speaker. In this technical solution, the vibration component includes a diaphragm, a first voice coil, a second voice coil, and a magnetic member. The diaphragm has a first surround and a second surround. The first surround is located within the area surrounded by the second surround, and there is a gap between the first surround and the second surround. The first voice coil is connected to the diaphragm, and the first voice coil is located between the first surround and the second surround, and vibrates under the magnetic force of the magnetic circuit component of the speaker, so that the part of the diaphragm between the first surround and the second surround vibrates under the vibration of the first voice coil, and forms a bass sound generating unit. The second voice coil is used to be disposed on one of the magnetic circuit component and the diaphragm, and the second voice coil corresponds to the first surround. The magnetic member is connected to the diaphragm, and the magnetic member is located within the first surround. The magnetic member is configured to correspond to the second voice coil and vibrate under the magnetic force of the second voice coil, so that the part of the diaphragm within the first surround vibrates under the vibration of the magnetic member, and forms a treble sound generating unit.

[0063] By dividing different regions on the same diaphragm using the first surround and the second surround, and driving the diaphragm between the first surround and the second surround to vibrate and generate sound by the magnetic force between the first voice coil and the magnetic circuit component, and driving the diaphragm inside the first surround to vibrate and generate sound by the magnetic force between the second voice coil and the magnetic member, a bass sound generating unit and a treble sound generating unit can be respectively formed. In this way, the same diaphragm can have different sound generating effects, which is equivalent to the bass sound generating unit and the treble sound generating unit sharing the same diaphragm, reducing the number of components, simplifying the structure of the speaker, making the speaker lighter and thinner, so as to reduce the space required for installing the speaker.

[0064] It should be noted that Figures 1 to 9 schematically shows a simplified diagram of each component in the vibration component and the speaker. The specific structure of the remaining components in the vibration component and the speaker is not limited to Figures 1 to 7 the illustration of Figure 10 and schematically shows the frequency response curve diagrams of the bass sound generating unit and the treble sound generating unit in the vibration component and the speaker of the embodiment of the present application.

[0065] The following will be a detailed description of the present application with reference to the accompanying drawings and specific embodiments:

[0066] Referring to Figure 1 、 Figure 2 and Figure 3 as shown, a vibration component 10 provided by an embodiment of the present application is used for a speaker. The vibration component 10 includes: a diaphragm 100, a first voice coil 200, a second voice coil 300, and a magnetic member 400.

[0067] The diaphragm 100 has a first surround 110 and a second surround 120 thereon. The first surround 110 is located within the area enclosed by the second surround 120, and there is a spacing between the first surround 110 and the second surround 120.

[0068] The first voice coil 200 is connected to the diaphragm 100, and the first voice coil 200 is located between the first surround 110 and the second surround 120, and vibrates under the magnetic force of the magnetic circuit assembly 600 of the speaker, so that the part of the diaphragm 100 between the first surround 110 and the second surround 120 vibrates under the vibration of the first voice coil 200, and a bass sounding unit is formed.

[0069] The second voice coil 300 is used to be arranged on one of the magnetic circuit assembly 600 and the diaphragm 100, and the second voice coil 300 corresponds to the first surround 110.

[0070] The magnetic member 400 is connected to the diaphragm 100, and the magnetic member 400 is located within the first surround 110. The magnetic member 400 is configured to correspond to the second voice coil 300 and vibrate under the magnetic force of the second voice coil 300, so that the part of the diaphragm 100 within the first surround 110 vibrates under the vibration of the magnetic member 400, and a treble sounding unit is formed.

[0071] The first surround 110 and the second surround 120 on the diaphragm 100 are made of the same material and are integrally formed. The integrated diaphragm 100 design can reduce the break points of the diaphragm 100, improve the strength of the diaphragm 100, enhance the acoustic performance of the diaphragm 100, and extend the service life of the diaphragm 100.

[0072] In the above embodiment, by dividing different areas on the same diaphragm 100 by using the first surround 110 and the second surround 120, and driving the diaphragm 100 between the first surround 110 and the second surround 120 to vibrate and sound by the magnetic force between the first voice coil 200 and the magnetic circuit assembly 600, and driving the diaphragm 100 inside the first surround 110 to vibrate and sound by the magnetic force between the second voice coil 300 and the magnetic member 400, a bass sounding unit and a treble sounding unit can be respectively formed, so that the same diaphragm 100 can have different sounding effects, which is equivalent to the bass sounding unit and the treble sounding unit sharing the same diaphragm 100, reducing the number of components, simplifying the structure of the speaker, making the speaker lightweight and thin, so as to reduce the space required for installing the speaker.

[0073] In specific implementation, the magnetic force between the first voice coil 200 and the magnetic circuit component 600 is the Lorentz force, that is, the magnetic circuit component 600 is fixed relative to the speaker, and the first voice coil 200 is subjected to the Lorentz force of the magnetic circuit component 600, thereby generating vibration. The magnetic force between the second voice coil 300 and the magnetic member 400 is the solenoid force, that is, the second voice coil 300 is fixed relative to the speaker, and the magnetic member 400 is subjected to the solenoid force of the second voice coil 300, thereby generating vibration.

[0074] It should be noted that the first folding ring 110 and the second folding ring 120 have different thicknesses and dimensions, so that different regions on the same diaphragm 100 emit high and low sound effects of different audio frequencies. For example, referring to Figure 10 As shown, the diaphragm 100 between the first folding ring 110 and the second folding ring 120 vibrates under the action of the magnetic force between the first voice coil 200 and the magnetic circuit component 600 to form a bass sound generating unit. The diaphragm 100 within the first folding ring 110 forms a treble sound generating unit under the action of the magnetic force between the second voice coil 300 and the magnetic member 400. At different frequency states, the bass sound generating unit and the treble sound generating unit have different response gains. When the frequency rises to the preset frequency, the response gains of the bass sound generating unit and the treble sound generating unit are the same. At this time, when the frequency continues to increase, the response gain of the treble sound generating unit is greater than that of the bass sound generating unit, and the high and low sound effects can be distinguished. The preset frequency at this time can be designed according to the thicknesses and dimensions of the first folding ring 110 and the second folding ring 120, and the embodiments of the present application do not limit this.

[0075] Referring to Figure 4 and Figure 5 As shown, when the sound generating frequency of the speaker is lower than the preset frequency, the diaphragm 100 between the first folding ring 110 and the second folding ring 120 and the diaphragm 100 within the first folding ring 110 vibrate simultaneously, such as Figure 4 vibrating in the direction of the arrow in, to ensure sufficient effective radiation area and improve acoustic performance. When the sound generating frequency of the speaker is higher than the preset frequency, as Figure 5 shown, the response of the diaphragm 100 within the first folding ring 110 is much greater than the response of the diaphragm 100 between the first folding ring 110 and the second folding ring 120. At this time, the diaphragm 100 within the first folding ring 110 vibrates to generate sound.

[0076] In a possible implementation manner, the first folding ring 110 and the second folding ring 120 can be one of a circular shape, a rectangular shape, a triangular shape, and a rhombic shape. As Figure 1 shown, in the embodiments of the present application, both the first folding ring 110 and the second folding ring 120 are rectangles with rounded corners. The embodiments of the present application do not limit the shapes of the first folding ring 110 and the second folding ring 120.

[0077] In a possible implementation, the first voice coil 200 is disposed on one side of the diaphragm 100 facing the magnetic circuit assembly 600. At least a part of the first voice coil 200 is located on the outer peripheral side of the magnetic circuit assembly 600, and there is a spacing between the first voice coil 200 and the magnetic circuit assembly 600.

[0078] In the above embodiment, there is a magnetic force between the magnetic circuit assembly 600 and the first voice coil 200. Disposing the first voice coil 200 on one side of the diaphragm 100 facing the magnetic circuit assembly 600 can enable the first voice coil 200 to stably receive the magnetic force of the magnetic circuit assembly 600, making the force on the first voice coil 200 stable, and can improve the response speed of the first voice coil 200 under the magnetic force of the magnetic circuit assembly 600.

[0079] In a possible implementation, the projection of the second voice coil 300 facing the diaphragm 100 is located within the first surround 110.

[0080] When the second voice coil 300 is disposed on the magnetic circuit assembly 600, it is used to be located within the mounting groove 601 of the magnetic circuit assembly 600.

[0081] When the second voice coil 300 is disposed on the diaphragm 100, it is used to be located within the avoidance groove 602 of the magnetic circuit assembly 600.

[0082] Referring to Figure 2 and Figure 3 As shown, the magnetic circuit assembly 600 has a mounting groove 601 for fixedly mounting the second voice coil 300, thereby improving the stability of the second voice coil 300. Referring to Figure 9 As shown, when the second voice coil 300 is disposed on the diaphragm 100, the magnetic circuit assembly 600 has an avoidance groove 602 to accommodate the second voice coil 300 and avoid interfering with the vibration of the second voice coil 300.

[0083] Continuing to refer to Figure 2 and Figure 3 As shown, the magnetic member 400 is disposed on one side of the diaphragm 100 facing away from the magnetic circuit assembly 600. In this way, the magnetic member 400 vibrates under the magnetic force of the second voice coil 300, and then drives the diaphragm 100 within the first surround 110 to vibrate. Disposing the magnetic member 400 on one side of the diaphragm 100 facing away from the magnetic circuit assembly 600 can improve the stability of the vibration of the diaphragm 100 within the first surround 110, and moreover, the magnetic member 400 can have the effect of pressing on the diaphragm 100 to avoid deformation of the diaphragm 100 within the first surround 110, thereby extending the service life of the diaphragm 100.

[0084] In a possible implementation, please continue to refer to Figure 1 、 Figure 2 and Figure 3As shown, the protruding directions of the first fold ring 110 and the second fold ring 120 are consistent, and both the first fold ring 110 and the second fold ring 120 protrude toward the side away from the magnetic circuit assembly 600 .

[0085] In the above embodiment, the protruding directions of the first fold ring 110 and the second fold ring 120 are ensured to be consistent, so that the part of the diaphragm 100 between the first fold ring 110 and the second fold ring 120 and the part of the diaphragm 100 inside the first fold ring 110 have the same stress, thereby avoiding deformation of the diaphragm 100 and avoiding reverse vibration of the diaphragm 100.

[0086] The first fold ring 110 and the second fold ring 120 both protrude toward the side away from the magnetic circuit assembly 600, which can increase the space between the diaphragm 100 and the magnetic circuit assembly 600 to adapt to the arrangement of other components while avoiding friction interference between the diaphragm 100 and the magnetic circuit assembly 600.

[0087] In a possible implementation, a back plate 500 is further included, and the back plate 500 is disposed on the diaphragm 100 and is located on the side of the diaphragm 100 away from the magnetic circuit assembly 600. Specifically, the back plate 500 is annularly wound between the first fold ring 110 and the second fold ring 120, and the back plate 500 corresponds to a portion of the diaphragm 100 between the first fold ring 110 and the second fold ring 120. The back plate 500 has a pressing effect on the diaphragm 100, thereby preventing the diaphragm 100 from being deformed and improving the stability of the diaphragm 100.

[0088] In order to improve the connection stability of the diaphragm 100 , the diaphragm 100 further has a connection portion 130 , which is connected to the second fold ring 120 , and the connection portion 130 is circumferentially arranged on the outer edge of the second fold ring 120 .

[0089] The connection portion 130 is used to connect to the frame 700 of the speaker.

[0090] Such an arrangement is equivalent to increasing the connection contact area between the diaphragm 100 and the frame 700 of the speaker, making the connection between the diaphragm 100 and the frame 700 more stable.

[0091] In a possible implementation, the present application further provides a speaker, comprising a speaker body and any one of the above-mentioned vibration components 10, wherein the vibration component 10 is connected to the speaker body. The specific structure of the vibration component 10 has been described above and will not be repeated here. It should be noted that the speaker comprises any one of the above-mentioned vibration components 10, that is, it has all the beneficial technical effects of the above-mentioned vibration components 10, can simplify the structure, and thus reduce the occupied space required when installing the speaker.

[0092] In a possible implementation, the speaker body includes:

[0093] The magnetic circuit component 600, at least a part of the magnetic circuit component 600 is arranged in the first voice coil 200 of the vibration component 10. An installation groove 601 or an avoidance groove 602 corresponding to the second voice coil 300 of the vibration component 10 is formed on one side of the magnetic circuit component 600 facing the diaphragm 100 of the vibration component 10.

[0094] Referring to Figure 3 , Figure 8 and Figure 9 As shown, the magnetic circuit component 600 includes a first washer 610, a first magnet 620 and a second washer 630. The first washer 610 is connected to the bottom of the frame 700 of the speaker. The two opposite sides of the first magnet 620 are respectively connected to the first washer 610 and the second washer 630. The first magnet 620 is configured to apply a magnetic force to the first voice coil 200 of the vibration component 10, so that the first voice coil 200 vibrates under the action of the magnetic force of the first magnet 620.

[0095] Optionally, continuing to refer to Figure 8 As shown, there is no specific limitation on the depth of the installation groove 601 here, and there is also no limitation on the thickness of the second voice coil 300, which can be designed according to specific sound generation requirements. The installation groove 601 can be formed only on the second washer 630, or can penetrate the second washer 630 and extend into the magnet. In order to improve the magnetic force stabilizing the second voice coil 300, referring to Figure 8 As shown, a center washer can also be arranged between the second voice coils 300 to achieve a magnetic stabilizing effect and make the vibration of the magnetic part 400 more stable.

[0096] Optionally, referring to Figure 9 As shown, the second voice coil 300 is connected to the diaphragm 100. Avoidance grooves 602 are formed at positions corresponding to the second voice coil 300 on the magnet and the second washer 630 to accommodate the second voice coil 300 and prevent the second voice coil 300 from interfering during vibration.

[0097] Furthermore, as Figure 9 shown, when the second voice coil 300 is connected to the diaphragm 100, the magnetic part 400 can be a non-magnetic plate body at this time, which can reduce the manufacturing cost. At this time, the second voice coil 300 only needs to vibrate under the action of the magnetic force of the first magnet 620.

[0098] In a possible implementation manner, referring to Figure 3 As shown, the magnetic circuit component 600 further includes a second magnet 640 and a third washer 650. One side of the second magnet 640 is connected to the first washer 610, and the other side is connected to the third washer 650, which is equivalent to the second magnet 640 being clamped between the first washer 610 and the third washer 650.

[0099] The second magnet 640 and the third washer 650 are circumferentially arranged outside the first magnet 620, and there is a spacing between the first magnet 620 and the second magnet 640, so that the first voice coil 200 of the vibration assembly 10 vibrates between the first magnet 620 and the second magnet 640.

[0100] By adding the second magnet 640 and the third washer 650, the magnetic field distribution of the first magnet 620 can be further stabilized and improved, so that the force on the first voice coil 200 or the second voice coil 300 is stable.

[0101] Here, with reference to Figure 6 and Figure 7 As shown, the pole distributions of the first magnet 620, the second magnet 640, and the magnetic member 400 are related technologies in the related art, and the present application does not limit this.

[0102] The first washer 610, the second washer 630, and the third washer 650 can be carbon steel plates, which are existing technologies in the related art, and the present application does not limit the first washer 610, the second washer 630, and the third washer 650.

[0103] In a possible implementation manner, the loudspeaker body further includes:

[0104] A frame 700, the frame 700 is connected to the diaphragm 100 of the vibration assembly 10. Specifically, the top of the frame 700 is connected to the connecting portion 130 of the diaphragm 100.

[0105] A plurality of suspensions 800, one end of the suspension 800 is connected to the frame 700, the other end of the suspension 800 is connected to the first voice coil 200 of the vibration assembly 10, and the plurality of suspensions 800 surround the circumferential side of the first voice coil 200.

[0106] In the above implementation manner, the suspension 800 is a connecting piece with a certain elastic effect, and the number of the suspensions 800 can be designed according to actual needs. In order to improve the stability of the first voice coil 200, the plurality of suspensions 800 are evenly wound around the circumferential side of the first voice coil 200.

[0107] The implementation principle of a vibration component 10 and a loudspeaker according to an embodiment of the present application is as follows: The vibration component 10 includes a diaphragm 100, a first voice coil 200, a second voice coil 300, and a magnetic member 400. The diaphragm 100 has a first surround 110 and a second surround 120. The first surround 110 is located within the area surrounded by the second surround 120, and there is a spacing between the first surround 110 and the second surround 120. The first voice coil 200 is connected to the diaphragm 100, and the first voice coil 200 is located between the first surround 110 and the second surround 120, and vibrates under the magnetic force of the magnetic circuit component 600 of the loudspeaker, so that a part of the diaphragm 100 between the first surround 110 and the second surround 120 vibrates under the vibration of the first voice coil 200, and a bass sound generating unit is formed. The second voice coil 300 is used to be disposed on one of the magnetic circuit component 600 and the diaphragm 100, and the second voice coil 300 corresponds to the first surround 110. The magnetic member 400 is connected to the diaphragm 100, and the magnetic member 400 is located within the first surround 110. The magnetic member 400 is configured to correspond to the second voice coil 300 and vibrate under the magnetic force of the second voice coil 300, so that a part of the diaphragm 100 within the first surround 110 vibrates under the vibration of the magnetic member 400, and a treble sound generating unit is formed.

[0108] By dividing different regions on the same diaphragm 100 by using the first surround 110 and the second surround 120, and driving the diaphragm 100 between the first surround 110 and the second surround 120 to vibrate and generate sound by the magnetic force between the first voice coil 200 and the magnetic circuit component 600, and driving the diaphragm 100 inside the first surround 110 to vibrate and generate sound by the magnetic force between the second voice coil 300 and the magnetic member 400, a bass sound generating unit and a treble sound generating unit can be respectively formed, so that the same diaphragm 100 can have different sound generating effects, which is equivalent to the bass sound generating unit and the treble sound generating unit sharing the same diaphragm 100, reducing the number of components, simplifying the structure of the loudspeaker, making the loudspeaker lighter and thinner, and reducing the space required for installing the loudspeaker.
