Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a speaker assembly in the related art. The speaker assembly 00 may comprise: the sounding panel 01, the shell 02 and the exciter 03. The casing 02 can be connected with the edge part of the sounding flat plate 01, and a containing cavity 011 can be arranged between the sounding flat plate 01 and the casing 02. The exciter 03 is fixed in the housing cavity 011. The housing 02 may include: a side plate 021, and a bottom plate 022 connected to the side plate 021, the exciter 03 may be fixed to a side of the bottom plate 022 adjacent to the sound emission panel 01. The overall thickness of the speaker unit 00 is the sum of the thickness of the sound emitting panel 01, the overall thickness of the exciter 03, and the thickness of the base plate 022 in the housing 02. This results in a large overall thickness of the speaker unit 00, and when the speaker unit 00 is incorporated in an electronic device, the overall thickness of the electronic device is also large, which is disadvantageous for the thinning of the electronic device.

Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a speaker assembly according to an embodiment of the present application, and fig. 3 is an exploded schematic diagram of the speaker assembly shown in fig. 2. The speaker assembly 000 may include: a sound-emitting panel 100, a stationary case 200, and an exciter 300.

The stationary case 200 in the speaker unit 000 may be connected to an edge portion of the sound emission panel 100, and a receiving cavity 201 is provided between the sound emission panel 100 and the stationary case 200. The stationary case 200 may have a mounting hole 202 communicating with a receiving cavity 201 between the sound emission panel 100 and the stationary case.

For a clearer view of the position relationship between the speaker assembly and the fixing housing, please refer to fig. 4, and fig. 4 is a cross-sectional view of a speaker assembly according to an embodiment of the present application. The exciter 300 in the speaker assembly 000 may have a first portion a1 distributed in the mounting hole 202 in the stationary case 200, and a second portion a2 distributed in the accommodating chamber 201 between the sound emitting panel 100 and the stationary case 200. The first portion a1 of the exciter 300 is fixedly connected to the stationary housing 200 in the mounting hole 202, and the second portion a2 of the exciter 300 is connected to a surface of the sound-emitting panel 100 adjacent to the stationary housing 200. For example, the second portion a2 of the actuator 300 and the surface of the sound board 100 adjacent to the fixed casing 200 may be fixedly connected by adhesion.

For example, the exciter 300 of the speaker unit 000 may be bonded to the surface of the sound emitting panel 100 adjacent to the stationary case 200. Thus, when the exciter 300 vibrates, the vibration of the exciter 300 can be transmitted to the sound emission panel 100 to vibrate the sound emission panel 100 to emit sound. For example, the sound board 100 may be a paper core cellular board, which has the characteristics of light weight and high strength.

In the present embodiment, the fixing case 200 for fixing the exciter 300 in the speaker assembly 000 has the mounting hole 202, the first portion a1 of the exciter 300 is located in the mounting hole 202 and fixedly connected to the fixing case 200, and the second portion a2 of the exciter 300 is located in the accommodating chamber 201 between the sound-emitting panel 100 and the fixing case 200. Thus, the overall thickness of the speaker assembly 000, i.e., the sum of the thickness of the sound emission panel 100 and the thickness of the exciter 300, is made small. When the speaker component 000 in the embodiment of the present application is integrated in an electronic device, the overall thickness of the electronic device can be effectively reduced, which is beneficial to the thinning of the electronic device.

In summary, the present application provides a speaker assembly, which may include: the sound production device comprises a sound production panel, a fixed shell and an exciter. A fixing shell used for fixing an exciter in the loudspeaker assembly is provided with a mounting hole, a first part in the exciter is located in the mounting hole and connected with the fixing shell, and a second part in the exciter is located in an accommodating cavity between a sounding panel and the fixing shell. Thus, the overall thickness of the speaker assembly, i.e., the sum of the thickness of the sound-emitting flat plate and the thickness of the driver, is made small. When the loudspeaker assembly in the embodiment of the application is integrated in the electronic equipment, the whole thickness of the electronic equipment can be effectively reduced, and the electronic equipment is favorably thinned.

Optionally, please refer to fig. 5, fig. 5 is a cross-sectional view of another speaker assembly provided in the embodiments of the present application. The exciter 300 in the speaker assembly 000 may further have: and a third portion a3 located outside the mounting hole 202 in the stationary case 200 and outside the receiving cavity 201 between the sound emission panel 100 and the stationary case 200. In this case, by disposing the third portion a3 in the exciter 300 outside the mounting hole 202 in the stationary housing 200 and outside the accommodating chamber 201, it is possible to secure the stationary housing 200 while the exciter 300 is fixed, so that the thickness of the entire sound-emitting flat panel 100 and the stationary housing 200 is small. Thus, when the speaker module 000 is integrated in an electronic device, the internal space of the electronic device can be effectively saved, which is further advantageous for the thinning of the electronic device.

In the embodiment of the present application, please refer to fig. 5, fig. 6, and fig. 7, fig. 6 is an exploded schematic view of an exciter provided in the embodiment of the present application, and fig. 7 is a structural schematic view of the exciter shown in fig. 6. The exciter 300 in the speaker assembly 000 may include: a toroidal support 301, an actuator body 302 and a plurality of resilient connectors 303. The ring bracket 301 of the exciter 300 is fixedly coupled to the stationary case 200 within the mounting hole 202 of the stationary case 200. At least part of the actuator body 302 may be located within the area enclosed by the toroidal support 301. A plurality of elastic connecting members 303 may be disposed between the annular bracket 301 and the actuator body 302, and both ends of each elastic connecting member 303 are fixedly connected to the annular bracket 301 and the actuator body 302, respectively. Wherein, a first gap B1 may be provided between any two adjacent elastic connectors 303. It should be noted that, in the practical application, it is only necessary to ensure that the radial stiffness of the elastic connection member 303 is greater than the axial stiffness thereof. In this case, the exciter body 302 and the ring bracket 301 are respectively connected by using a plurality of elastic connection members 303 spaced apart along the circumferential direction of the exciter body 302, and the ring bracket 301 is fixedly connected to the stationary case 202. In this manner, the actuator body 302 can be stably fixed to the stationary case 200 by the engagement of the plurality of elastic connection members 303 and the annular bracket 301. In addition, the first gap B1 is formed between any two adjacent elastic connectors 303 in the plurality of elastic connectors 303. Therefore, heat generated during the operation of the exciter body 302 can be dissipated out through the first gap B1 in time, and the service life of the speaker assembly 000 is ensured. In the related art, a closed space is enclosed by the magnetic conduction part, the voice coil, the elastic wave and the sounding flat plate in the exciter, a magnetic circuit of the loudspeaker component can generate a large amount of heat in the working process, the sounding flat plate is a paper core honeycomb plate which is a heat insulation material, and the structure is not favorable for heat dissipation of the magnetic circuit and has the risk of burning out the voice coil in long-term operation.

Alternatively, please refer to fig. 8 and 9, in which fig. 8 is an exploded schematic view of an actuator body according to an embodiment of the present disclosure, and fig. 9 is a sectional view of the actuator body shown in fig. 8. The actuator body 302 in the actuator 300 may include: a voice coil 3021 and a magnetic component 3022. The voice coil 3021 may be fixedly connected to the elastic connector 303, and bonded to a surface of the sound generating flat plate 100 close to the fixing case 200. In this way, when the driver 300 of the speaker unit 000 drives the sound emission panel 100 to emit sound, the voice coil 3021 and the magnetic member 3022 are not directly connected to each other, so that the voice coil 3021 of the driver body 302 is moved in the axial direction of the voice coil 3021 by the magnetic field generated by the magnetic member 3022 after being energized. The plurality of elastic connections 303 elastically deform to follow the voice coil 3021 in the axial direction of the voice coil 3021, and the plurality of elastic connections 303 can restrict the movement of the voice coil 3021 in the radial direction of the voice coil 3021, ensuring that the voice coil 3021 does not collide with the magnetic member 3022. It should be noted that the elastic connection members 303 are elastic waves in the exciter 300, and the elastic connection members 303 may be made of any one of rubber, woven cloth, Polyurethane (PU) and Acrylonitrile Butadiene Styrene (ABS), which is not specifically limited in this embodiment. It should be noted that, in an actual process, the plurality of elastic connection members 303 and the annular bracket 301 may be integrally formed, or the plurality of elastic connection members 303 and the annular bracket 301 may be separately formed and then assembled with the actuator body 302 after being connected into an integral structure, which is not limited in this embodiment of the present invention.

As an example, as shown in fig. 8 and 9, the magnetic component 3022 in the present application may include: a first magnetic conductive member 30221, a magnet 30222, and a second magnetic conductive member 30223 which are laminated in a direction close to the sound emission panel 100. The first magnetic conductive member 30221 has a bearing cavity a1, the magnet 30222 is disposed on the bottom surface of the first magnetic conductive member 30221 in the bearing cavity a1, and the second magnetic conductive member 30223 is disposed on the magnet 30222. The magnet 30222 and the second magnetic conductive member 30223 have a certain gap, i.e., a magnetic air gap, with the inner wall surface of the first magnetic conductive member 30221. First and second magnetically permeable members 30221 and 30223 may be used to direct the magnetic field generated by magnet 30222 into the magnetic air gap to generate a steady magnetic field in the magnetic air gap. By way of example, the magnet 30222 may be a permanent magnet.

In the embodiment of the present application, the voice coil 3021 in the actuator body 302 may include: an annular voice coil former and a conductive coil (not shown) that may be wound around the outside of the voice coil former. One side of the annular voice coil framework close to the sounding flat plate 100 can be bonded with the sounding flat plate 100, and the side of the annular voice coil framework is connected with the elastic connecting piece 303. The conductive coil is used for receiving an audio signal, and when the conductive coil receives the audio signal, the conductive coil generates current. At this time, the conductive coil can drive the voice coil bobbin to move along the direction perpendicular to the sounding flat plate 100 under the magnetic field in the magnetic air gap.

Optionally, please refer to fig. 10, fig. 10 is a top view of an actuator according to an embodiment of the present application. The elastic connection 303 in the actuator 300 may include: a flexible arm 3031, a first sub connector 3032 connected to one end of the flexible arm 3031, and a second sub connector 3033 connected to the other end of the flexible arm 3031. The first sub connector 3032 may be fixedly connected to the actuator body 302, and the second sub connector 3033 may be fixedly connected to the annular support 301. The extending direction of the elastic arm 3031 may intersect with the extending direction of the first sub connector 3032 and may intersect with the extending direction of the second sub connector 3033. In this case, the first sub-connector 3032 and the second sub-connector 3033 are connected by the elastic arms 3031 in the elastic connector 303, respectively, and the extending direction of the elastic arms 3031 intersects the extending direction of the first sub-connector 3032 and intersects the extending direction of the second sub-connector 3033. In other words, in the annular space between the annular bracket 301 and the actuator body 302, compared with the elastic connecting member adopting a straight strip shape, the length of the elastic connecting member 303 in the present application is longer, and thus the connection strength between the actuator body 302 and the annular bracket 301 is ensured. In addition, the joint of the second sub-connector 3033 and the annular bracket 301 is far away from the joint of the first sub-connector 3032 and the actuator body 302, so that the moment arm length between the two joints is increased. In this way, the vibration of the voice coil 3021 connected to the elastic connection member 303 is facilitated, and the sound emission effect of the speaker unit 000 is improved. It should be noted that the structures of the plurality of elastic connection members 303 in the actuator 300 may be the same or different, and the following embodiments of the present application are schematically illustrated by taking the example that the structures of the plurality of elastic connection members 303 are the same.

In the embodiment of the present application, please refer to fig. 9, fig. 11 and fig. 12, fig. 11 is an exploded schematic view of a speaker assembly provided in the embodiment of the present application, and fig. 12 is a sectional view of the speaker assembly shown in fig. 11. The exciter 300 in the speaker assembly 000 may further include: a plurality of connection plates 304. A plurality of connecting plates 304 may be located between the ring-shaped support 301 and the exciter body 302, and both ends of each connecting plate 304 are fixedly connected to the ring-shaped support 301 and the exciter body 302, i.e. one end of the connecting plate 304 is connected to the magnetic component 3022 in the exciter body 302. Wherein, any two adjacent connection plates 304 in the plurality of connection plates 304 may have a second gap C1 therebetween, and the second gap C1 may be in communication with the first gap B1.

In this case, the exciter body 302 and the ring holder 301 are connected by using a plurality of connection plates 304 that are distributed at intervals in the circumferential direction of the exciter body 302, respectively, and the ring holder 301 is fixedly connected to the stationary case 202. In this manner, the actuator body 302 is stably fixed to the stationary case 200 by the engagement of the plurality of connection plates 304 and the ring bracket 301. And the connection plate 304 can be driven by the annular bracket 301 to bend and deform along the axial direction of the voice coil 3021, without generating compressive deformation of the connection plate itself, so as to further prevent the voice coil 3021 from moving along the radial direction of the connection plate, it should be noted that in the practical application process, it is only required to ensure that the radial stiffness of the connection plate 304 is greater than the axial stiffness thereof.

In addition, the second gap C1 is formed between any two adjacent connecting plates 304 in the plurality of connecting plates 304, and the second gap C1 is communicated with the first gap B1 between two adjacent elastic connecting pieces 303. In this way, heat generated by the exciter 300 during operation can be dissipated through the first gap B1 and the second gap C1 in time. That is, it is not necessary to provide a heat dissipation hole on the side surface of the fixing case 200 to dissipate heat generated by the exciter 300, and the overall strength of the fixing case 200 is ensured. For example, the connection plate 304 may be a plate-shaped structure made of Acrylonitrile Butadiene Styrene (ABS), or may be made of other materials, which is not specifically limited in this embodiment. In the related art, the exciter 03 is usually located in the closed accommodating cavity 011 between the sound emission panel 01 and the housing 02, and in order to dissipate heat of the exciter 03, heat dissipation holes (not shown) are usually formed in a side plate 021 of the housing 02. Thus, the overall strength of the housing 02 is liable to be low.

It should be noted that, as shown in fig. 6, 10, 11 and 12, the toroidal support 301 in the exciter 300 may include: a first sub-annular support 3011 and a second sub-annular support 3012 connected to each other. The first sub-annular support 3011 may be fixedly connected to the elastic connection element 303 and the fixing shell 200, respectively, and the second sub-connection 3012 may be fixedly connected to the connection plate 304 and the fixing shell 200, respectively. In an actual process, the first sub-annular support 3011 and the second sub-annular support 3012 may be separately manufactured and then connected to the stationary casing 200, respectively, to implement the installation and fixation of the stationary casing 200 to the exciter 300.

Alternatively, as shown in fig. 11 and 12, the actuator body 302 in the actuator 300 may further include: an auxiliary connecting ring 3023 sleeved on the magnetic component 3022, wherein the auxiliary connecting ring 3023 can be fixedly connected with the connecting plate 304. The auxiliary connecting ring 3023 is fixedly connected to the first magnetic conductive member 30221 of the magnetic component 3022. In this case, by fixedly coupling the connection plate 304 with the auxiliary connection ring 3023, the strength of coupling the magnetic member 3022 coupled with the auxiliary connection ring 3023 with the connection plate 304 is increased, thereby securing the stability of the fixing of the stationary case 200 to the exciter 300. For example, the auxiliary connecting ring 3023 and the connecting plate 304 may be integrally formed, or the auxiliary connecting ring 3023 and the connecting plate 304 may be separately manufactured and then connected, which is not specifically limited in the embodiments of the present invention.

In the present application, since the elastic connection member 303 and the connection plate 304 are connected to the stationary case 200. Therefore, the voice coil 3021 will drive the elastic connection member 303 to move when vibrating, the movement of the elastic connection member 303 is transmitted to the connection plate 304 through the fixed shell 200, and the connection plate 304 can drive the first magnetic conductive member 30221 to vibrate forcedly. The vibration of the first magnetic conductive member 30221 may reversely affect the sound board 100 through the fixing case 200, and the vibration of the sound board 100 may be better excited to improve the middle-high frequency performance. Note that, since the amplitude of the low-frequency sound is large, the amplitude of the medium-high frequency sound is small, and the vibration of the first magnetic conductive member 30221 is small amplitude vibration. Therefore, the first magnetic conductive member 30221 can better excite the middle-high frequency performance of the sound emission panel 100. In the practical application process, the high-medium-high frequency is mainly used for the ultrathin flat panel loudspeaker.

Optionally, please refer to fig. 13, fig. 13 is a bottom view of an actuator according to an embodiment of the present application. The connection plate 304 in the exciter 300 may include: a connecting arm 3041, a third sub-connecting member 3042 connected to one end of the connecting arm 3041, and a fourth sub-connecting member 3043 connected to the other end of the connecting arm 3041. The third sub-link 3042 may be fixedly connected to the actuator body 302, and the fourth sub-link 3043 may be fixedly connected to the annular bracket 301. The extending direction of the connecting arm 3041 may intersect the extending direction of the third sub-link 3042 and the extending direction of the fourth sub-link 3043.

In this case, the third sub-link 3042 and the fourth sub-link 3043 are connected by a connection arm 3041 in the connection plate 304, respectively, and the extension direction of the connection arm 3041 intersects with the extension direction of the third sub-link 3042 and with the extension direction of the fourth sub-link 3043. That is, in the annular space between the annular bracket 301 and the actuator body 302, the length of the connecting plate 304 in the present application is longer than that of a connecting plate in a straight strip shape, so that the connection strength between the actuator body 302 (i.e., the magnetic component therein) and the annular bracket 301 is ensured. In addition, the distance between the joint of the fourth sub-link 3043 and the annular bracket 301 and the joint of the third sub-link 3042 and the actuator body 302 is relatively long, so that the length of the moment arm between the two joints is increased. In this way, the vibration of the actuator body 302 connected to the connection plate 304 is facilitated, and the sound-producing effect of the speaker unit is improved. It should be noted that the structures of the plurality of connecting plates 304 in the exciter 300 may be the same or different, and the following embodiments of the present application are schematically illustrated by taking the example that the structures of the plurality of connecting plates 304 are the same.

In the embodiment of the present application, as shown in fig. 13, the plurality of elastic connectors 303 in the exciter 300 may correspond to the plurality of connection plates 304 one-to-one, and the orthographic projection of each elastic connector 303 in the sound emission panel 100 may be located in the orthographic projection of the corresponding connection plate 304 in the sound emission panel 100. In this case, the orthographic projection of each elastic connector 303 in the sound board 100 can be located in the orthographic projection of the corresponding connecting plate 304 in the sound board 100, that is, the overlapping area of the orthographic projections of the first gap B1 and the second gap C1 in the sound board 100 can be made. In this way, heat generated when the actuator 300 operates can be directly radiated through the first gap B1 and the second gap C1, and the efficiency of radiating heat through the first gap B1 and the second gap C1 is further improved. For example, the number of the elastic connection members 303 and the number of the connection plates 304 may be four, or may be other numbers, which is not specifically limited in the embodiments of the present application. It should be noted that the number of the elastic connection members 303 and the number of the connection plates 304 may be different in other realizable manners.

Optionally, please refer to fig. 14 and 15, in which fig. 14 is a schematic structural diagram of a sound emitting panel provided in an embodiment of the present application, and fig. 15 is an exploded schematic diagram of the sound emitting panel shown in fig. 14. The sound emission panel 100 in the speaker assembly 000 may include: paper core 101, first skin 102 and second skin 103. The first skin 102 covers one surface of the paper core 101, which faces away from the voice coil 3021, and the second skin 103 is arranged opposite to the first skin 102 and covers one surface of the paper core 101, which is close to the voice coil 3021. The paper core 101 is interconnected with a first skin 102 and a second skin 103, respectively, to form the sound board 100. Thus, since the cellular paper core is present in the sound board 100, the sound generated by the vibration of the sound board 100 is in a multi-mode state on the entire surface of the sound board 100, so that the sound board 100 can vibrate in a plurality of positions as a whole, and the front surface of the sound board 100 can sound.

In summary, the present application provides a speaker assembly, which may include: the sound production device comprises a sound production panel, a fixed shell and an exciter. A fixing shell used for fixing an exciter in the loudspeaker assembly is provided with a mounting hole, a first part in the exciter is located in the mounting hole and connected with the fixing shell, and a second part in the exciter is located in an accommodating cavity between a sounding panel and the fixing shell. Thus, the total thickness of the speaker assembly, i.e., the sum of the thickness of the sound emitting panel and the thickness of the driver, is made small. When the loudspeaker assembly in the embodiment of the application is integrated in the electronic equipment, the whole thickness of the electronic equipment can be effectively reduced, and the electronic equipment is favorably thinned.

The embodiment of the application also provides the electronic equipment which can be a liquid crystal television, a plasma television and a laser television. Referring to fig. 16, fig. 16 is a block diagram of an electronic device according to an embodiment of the present disclosure. The electronic device may include: an apparatus body 001, and a speaker unit 000 connected to the apparatus body. The speaker assembly 000 may be any of the speaker assemblies described in the above embodiments. Thus, when the speaker module 000 is mounted in an electronic device, the thickness of the electronic device as a whole can be reduced, which is advantageous for the reduction in thickness of the electronic device. The speaker component 000 may be used to play sound, and the number of the speaker components 000 may be one or more, which is not limited in this embodiment.
