DETAILED DESCRIPTION

[0033] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0038] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] With the development of display device technology, users have gradually increased their requirements for the visual and auditory effects of display devices such as televisions. Visually, thinning of display devices such as televisions is an industry trend. Auditorily, display devices usually use built-in speakers to output sound signals.

[0040] However, as display devices become thinner, the installation space of the speakers on the display devices becomes smaller and smaller, and the sound quality of the display devices becomes worse and worse, thus failing to meet user requirements.

[0041] In the related art, the speakers used in display devices usually output sound through physical vibration. The output volume is achieved by the diaphragm or vibrating body itself. There needs to be a vibration gap between the diaphragm and the internal components of the display device, and the volume of the diaphragm affects the intensity of the output volume. Therefore, the volume of traditional speakers cannot be reduced and must occupy the internal space of the display device, which is not conducive to the thinning of the display device.

[0042] In addition, due to the limited space inside the display device, the volume of the speaker cannot be increased arbitrarily, thus limiting the intensity of the sound field output by the speaker inside the display device. In display devices such as televisions, multiple groups of different speakers are usually set at different positions to create different sound field patterns, which increases the number of speakers required for the display device, making the problem of speakers occupying the internal space of the display device more serious.

[0043] Due to the above reasons, the speakers used in the display devices in the related art have the disadvantages of occupying space and insufficient output sound field strength. Therefore, how to solve the above problems through structural improvement has become one of the important issues to meet the dual requirements of hearing and vision of display devices.

[0044] The sound-generating structure in the display device is a speaker. Figure 1 The cross-sectional schematic diagram of a speaker in a display device in the related art is shown, and the speaker is installed on the side of the rear shell 004 of the display device facing the display module 005.

[0045] The sound box includes a box shell 002, a sound guide baffle 001, and a speaker 003, wherein the box shell 002 is close to the display module 005, and the sound guide baffle 001 is close to the rear shell 004; the box shell 002 and the sound guide baffle 001 are both rigid components, and the two together enclose a receiving cavity; the speaker 003 is located in the receiving cavity and is installed on the box shell 002. As the diaphragm of the speaker 003 vibrates toward the rear shell 004, the sound guide baffle 001 guides the sound waves of the speaker 003, for example, to the side of the display device.

[0046] There is a gap a between the sound guide baffle 001 and the diaphragm of the speaker 003, there is also a gap b between the sound guide baffle 001 and the rear shell 004, and the sound guide baffle 001 itself has thickness, which results in a larger thickness of the entire speaker box.

[0047] Since the frame of the display device in the related art is narrow, there is not enough space to arrange the speaker. Therefore, the speaker must be set on the back of the display module. The diaphragm of the speaker has a large diameter, and the surface where the diameter of the diaphragm of the speaker is located is parallel to the display surface of the display device. Therefore, the diaphragm requires a certain vibration interval, so that the interval a cannot be omitted; since the speaker emits sound backwards, it is necessary to set a guiding member (such as a sound guide baffle 001) to guide the sound waves, that is, the guiding member cannot be omitted. In order to avoid the contact between the guiding member and other components of the display device (such as the back shell) and generate noise, a gap also needs to be reserved between the guiding member and the other components, that is, the interval b cannot be omitted. In this way, the speaker needs to provide a chamber to install the speaker, and provide a vibration interval and installation space for the guiding member, resulting in the thickness of the speaker cannot be reduced.

[0048] The researchers and developers of this application have conducted a detailed study on the components in the structure of the speaker that realize vibration and sound generation, and re-examined and analyzed the necessity of each component for the realization of the speaker function: for the speaker structure, the speaker is indispensable as a sound-generating element; it is necessary to provide an installation position for the speaker; it is necessary to form a sound cavity and side sound outlets, and provide a vibration interval for the speaker.

[0049] Through analysis, the R&D personnel of this application believe that the attached Figure 1 The sound guide baffle 001 can be omitted, and omitting the sound guide baffle 001 can save the thickness of the sound guide baffle itself and the interval b, which contributes greatly to reducing the thickness of the sound box. How to form a sound wave guiding structure becomes a new problem.

[0050] The researchers of this application continue to study the display device and its speaker structure in the related technology. The rear shell of the display device, as an appearance part, plays the role of shielding the internal structure of the display device, and its structural stability is very important. Therefore, there is usually a gap between the rear shell and the speaker, which can not only prevent the sound wave vibration of the speaker from affecting the structural stability of the whole device, but also reduce the possibility of noise generated by the vibration of the rear shell.

[0051] The researchers of this application continue to analyze the speaker structure in related technologies, such as Figure 1 As shown, the sound guide baffle 001 is opposite to the rear shell 004 and there is a gap between them. At least part of the rear shell 004 is plate-shaped, similar to the structure of the sound guide baffle 001. Therefore, the researchers of this application believe that the sound guide baffle 001 can be replaced by the rear shell 004 to guide the sound waves so that the sound is emitted from the side of the speaker. But this brings a new problem: the rear shell is subjected to the vibration of sound waves, how to reduce the possibility of noise and ensure the acoustic effect.

[0052] The researchers of this application conducted experiments by directly connecting the box shell to the back shell and found that the back shell vibrated greatly, which not only affected the stability of the whole structure, but also caused poor acoustic effects of the display device. This is because both the box shell and the back shell are rigid parts. Under the action of vibration, the two are in hard contact and generate noise. In addition, the box shell, as the installation part of the speaker, and the back shell, as the appearance part, both need to have rigid characteristics.

[0053] Therefore, the researchers of the present application considered realizing an elastic connection between the box shell and the back shell by means of an elastic component; considering the closedness of the accommodating cavity at positions other than the sound outlet, in order to reduce the possibility of sound leakage at positions other than the sound outlet, the researchers of the present application arranged an elastic sound guide between the box shell and the back shell, and formed a sound cavity with a sound outlet by utilizing the back shell, the sound guide and the box shell. The sound guide closes the positions between the box shell and the back shell except the sound outlet, thereby reducing the possibility of sound leakage in the sound cavity and concentrating the sound waves as much as possible from the sound outlet. , which is beneficial to improving the acoustic effect; when the sound wave is transmitted to the back shell, due to the elasticity of the sound guide, the sound guide elastically deforms to absorb part of the sound wave energy on the back shell, reduce the vibration force of the back shell, and ensure the stability of the back shell connection structure; it is beneficial to reduce the possibility of noise generated by vibration of the back shell and ensure the acoustic effect; and, when the sound wave is transmitted to the sound guide, the sound guide can not only guide the sound wave to the sound outlet, but also absorb part of the sound wave energy and reduce the reflection of the sound wave, so that the sound response in each frequency band is smoother and the sound quality effect is better.

[0054] Since the sound guide baffle is removed, the thickness of the sound guide baffle is saved, the gap between the sound guide baffle and the rear shell is saved, and the thickness of the speaker box is reduced. Therefore, the display device of the embodiment of the present application has a speaker box with a small thickness, which is conducive to the thin and light design of the display device; and it can also have good sound quality.

[0071] Combination Figure 4 The display device 10 provided in some embodiments of the present application includes a display module 100, which is used to display image information such as text and images. The display module 100 has a display side and a back side opposite to each other along the thickness direction of the display device, wherein the display side of the display module 100 faces the front side of the display device.

[0072] In some embodiments, the display module 100 includes a display panel, and the display panel is configured to display image information such as text, images, etc. Exemplarily, the display panel may be a liquid crystal display panel.

[0073] In some embodiments, the display module 100 further includes a backlight assembly, which is located on one side of the display panel and provides backlight for the display panel, so that the display panel can modulate the backlight as needed to display different images.

[0074] In some embodiments, the display device 10 includes a rear case 200, which is located at the back side of the display module 100. The rear case 200 may be an outer shell of the display device 10, and the material of the rear case 200 may be plastic, metal, etc.

[0075] There may be a gap between the rear case 200 and the display module 100 , so that control components, cables, etc. of the display device 10 may be disposed between the rear case 200 and the display module 100 , thereby simplifying the appearance of the display device.

[0076] In some embodiments, the display device 10 includes a first speaker 300 , which is a sound-emitting component of the display device 10 and is disposed between the rear housing 200 and the display module 100 .

[0077] Continue to refer to Figure 4 In some embodiments, the first sound box 300 includes a first speaker 320 , which is a sound-emitting element of the first sound box 300 .

[0078] In some embodiments, the first speaker 320 is a mid-range speaker. Exemplarily, the sound wave frequency range of the first speaker 320 is 200 Hz to 8 KHz, or the sound wave frequency range of the first speaker 320 is 200 Hz to 10 KHz.

[0079] In some embodiments, the first speaker 320 is a full-range speaker or a mid-high frequency speaker. Exemplarily, the sound wave frequency range of the first speaker 320 is 200 Hz to 20 KHz.

[0080] Exemplarily, the first speaker 320 may include a diaphragm, a magnetic group, a bracket, a basin, a voice coil, etc. The bracket is used to install the diaphragm, the magnetic group, the basin, and the voice coil, etc. The diaphragm vibrates in cooperation with the magnetic group and the voice coil, thereby producing sound.

[0081] In some embodiments, the first sound box 300 includes a box casing 310 , which is an outer shell of the first sound box 300 and provides a mounting position for the first speaker 320 .

[0082] In some embodiments, the box shell 310 may be an injection molded shell. For example, the box shell 310 is a plastic shell that is injection molded and is easy to prepare.

[0083] In some embodiments, the box shell 310 can be a metal shell with high structural strength. When having the same structural strength, the metal box shell 310 can be thinner, which is beneficial to reducing the thickness of the first speaker 300. Moreover, the metal box shell 310 can contact the magnetic group of the first speaker 320, which is beneficial to increase the heat dissipation area of ​​the first speaker 320, thereby improving the heat dissipation effect of the first speaker 320.

[0084] In some embodiments, the non-metallic shell portion can be an injection molded shell portion, such as a plastic shell portion, and the metal shell portion serves as an insert during injection molding of the injection molded shell portion, and is integrally formed with the injection molded shell portion. Not only does it have high structural strength, but the metal shell portion of the box shell 310 is in contact with the magnetic group of the first speaker 320. For example, the metal shell portion is in contact with the magnetic yoke of the first speaker 320, which is beneficial to improving the heat dissipation effect of the first speaker 320.

[0085] In some embodiments, the box shell 310 is installed on the back plate of the display device, and the back plate of the display device is located between the backlight assembly and the rear shell 200, and the back plate can provide an installation position for the backlight assembly. In this way, the box shell 310 can be installed on the back plate, and then the rear shell 200 is assembled, so that the assembly of the display device is simple; and it is convenient to electrically connect the first speaker 300 to the main control board of the display device, and when the rear shell 200 is disassembled, there is no need to disassemble the first speaker 300, and the disassembly is simple and convenient.

[0086] In some embodiments, the box shell 310 and the back panel are elastically connected, and the sound wave vibration force on the box shell 310 is converted into an elastic force between the box shell 310 and the back panel, which can avoid the noise caused by the rigid contact between the box shell 310 and the back panel, and can reduce the vibration noise between the box shell 310 and the back panel, which is beneficial to improving the acoustic effect of the display device 10.

[0087] Exemplary, combined Figure 5 The box shell 310 is provided with a fixing hole 311, and an elastic ring 312 is provided in the fixing hole 311. The circumferential side surface of the elastic ring 312 is provided with an annular groove, so that the elastic ring 312 is sleeved on the edge of the fixing hole 311; the elastic ring 312 is provided with a through hole, so that the fastener passes through the through hole and is fixedly connected to the rear shell 200. In this way, not only can the box shell 310 and the back plate be elastically connected in the axial direction of the fixing hole 311, but also the box shell 310 and the fastener can be elastically connected in the circumferential direction of the fixing hole 311, so as to avoid rigid contact between the box shell 310 and the back plate, and also avoid rigid contact between the box shell 310 and the fastener.

[0088] In related technologies, for example Figure 1 In the structure shown, the box shell 002 is installed on the rear shell 004. Due to the existence of the sound guide baffle 001, the distance between the box shell 002 and the sound guide baffle 001 is relatively large, and the height of the column forming the threaded hole on the rear shell 004 is relatively large, which not only requires more materials, but also has great difficulty in molding and demoulding when the rear shell 004 is formed by injection molding.

[0089] Compared with the related art, the spacing between the box shell 310 and the rear shell 200 in some embodiments of the present application is smaller, which helps to reduce the difficulty of connecting the fasteners with the threaded holes and improve the assembly efficiency; and the height of the column forming the threaded holes on the rear shell 200 is smaller, which reduces the material consumption and helps to improve the structural stability; when the rear shell 200 is an injection molded part, it helps to reduce the difficulty of molding.

[0090] In some embodiments, the first speaker 320 is mounted on a side of the housing 310 facing the rear housing 200 , such that the first speaker 320 is directly opposite to the rear housing 200 .

[0091] Since the diaphragm needs to vibrate back and forth to produce sound, a vibration space needs to be reserved for the diaphragm of the first speaker 320. In some embodiments of the present application, there is a gap between the diaphragm of the first speaker 320 and the rear housing 200, so that the diaphragm vibrates back and forth in the gap to produce sound.

[0092] The diaphragm of the first speaker 320 faces the rear case 200 of the display device 10 , so that the first speaker 320 emits sound toward the rear side of the display device 10 , which makes the acoustic effect of the display device 10 poor and affects the hearing effect.

[0093] To this end, in some embodiments, the display device 10 includes a first sound guide 400, which is used to guide backward sound waves to the side so that the sound waves are emitted from the side of the display device 10, for example, the top side, the bottom side, the left side or the right side of the display device 10, so as to improve the acoustic effect of the display device 10.

[0094] The first sound guide member 400 is located between the box shell 310 and the rear shell 200 , and the first sound guide member 400 contacts the box shell 310 and the rear shell 200 respectively. The first sound guide member 400 , the box shell 310 and the rear shell 200 together form a first sound cavity 301 , providing an installation space for the first speaker 320 .

[0095] In some embodiments, in combination Figures 4 to 6 A mounting groove 313 is formed on the box shell 310, and the mounting groove 313 has a first opening facing the rear shell 200; the first speaker 320 is installed in the mounting groove 313, so that the thickness of the first speaker 320 occupies the thickness space of the box shell 310, which is conducive to reducing the thickness of the first speaker 300.

[0096] In some embodiments of the present application, the first speaker 320 is located in the first sound cavity 301, the first sound guide 400 forms at least part of the first sound outlet 302, and the first sound outlet 302 is connected to the first sound cavity 301. In this way, at least part of the sound waves of the first speaker 320 are transmitted through the first sound outlet 302 under the restriction of the first sound guide 400 and the rear shell 200, so as to realize the side sound output of the first speaker 300.

[0097] The side sound outlet of the first speaker 300 can be understood as that the first speaker 300 has a front side and a rear side along the thickness direction of the display device, and the first sound outlet 302 is arranged on other sides of the first speaker 300 except the front side and the rear side, such as the bottom side.

[0098] Therefore, in the display device of the embodiment of the present application, the first sound box 300 eliminates the sound guide baffle in the existing sound box, and uses the box shell 310, the first sound guide member 400 and the rear shell 200 to jointly enclose a first sound cavity 301 for accommodating the first speaker 320. The diaphragm of the first speaker 320 sounds toward the rear shell 200, and the first sound cavity 301 is used to guide the sound waves to the first sound outlet 302 so that the sound waves are transmitted, thereby ensuring the sound effect of the first sound box 300. Since the sound guide baffle is eliminated, the thickness of the sound guide baffle is saved, the gap between the sound guide baffle and the rear shell is saved, and the thickness of the sound box is reduced.

[0099] Combination Figure 6 , the first sound guide 400 is located outside the first speaker 320, so that the first speaker 320 is located in the first sound cavity 301. In some embodiments, the first sound guide 400 can be only arranged around the outside of the diaphragm of the first speaker 320, and in this case, the first sound guide 400 can contact the basin frame of the first speaker 320.

[0100] In some embodiments, the first sound guide member 400 is provided with a notch or a break to form the first sound outlet 302 alone, and the structure is simple.

[0101] In other embodiments, the first sound guide 400 and the box shell 310 together define the first sound outlet 302 , which helps to increase the sound outlet area of ​​the first sound outlet 302 .

[0102] Continue to refer to Figure 5 and Figure 6 In some embodiments, the first sound guide 400 is formed with a break 401, and the first sound guide 400 is an open ring, so that the first sound guide 400 is half-surrounded by the outside of the first speaker 320. The break 401 forms at least a portion of the first sound outlet 302. In this way, the first sound guide 400 can be formed by splicing multiple sections of strip-shaped sound guides, and the break 401 is formed at the same time, which not only makes the formation structure of the first sound guide 400 simple, without the need to additionally design a mold to process the first sound guide 400; but also helps to improve the flexibility of the size and shape of the first sound guide 400, and form sound cavities of different sizes and shapes.

[0103] In some embodiments, the length of the cutout 401 formed by the first sound guide 400 may have a certain deviation from the diameter of the diaphragm of the first speaker 320. For example, the length of the cutout 401 is slightly larger than the diameter of the diaphragm, which will not block the transmission of sound waves, and can also prevent the cutout 401 from being too large, causing the sound waves to disperse, and affecting the structural strength of the first sound guide 400. For another example, the length of the cutout 401 is slightly smaller than the diameter of the diaphragm, and its blocking effect on the sound waves can be ignored, thereby ensuring the structural strength and support of the first sound guide 400.

[0104] In some embodiments, the mounting groove 313 extends to one side edge of the box shell 310, so that the mounting groove 313 forms a second opening facing the side of the box shell 310. The side of the box shell 310 here refers to the side other than the front side and the rear side of the box shell 310. In this way, the first speaker 320 is close to the edge of the box shell 310, which is convenient for lateral sound output.

[0105] In some embodiments, the second opening of the mounting groove 313 is at least partially opposite to the break 401 of the first sound guide 400. With this arrangement, the second opening and the break 401 together form the first sound outlet 302, which can increase the sound outlet area of ​​the first sound outlet 302, thereby improving the sound effect; and the first sound outlet 302 has no blocking structure, thereby improving the sound effect.

[0106] Exemplarily, the two ends of the first sound guide 400 are respectively located at the two ends of the second opening, so that the break 401 of the first sound guide 400 is opposite to the second opening, which can not only ensure the sound outlet area, but also avoid the sound outlet area being too large to cause dust and other impurities to enter the sound cavity.

[0107] In some embodiments of the present application, the mounting groove 313 formed on the box shell 310 omits part of the side wall. For example, when the mounting groove 313 is a rectangular groove, it has a groove bottom wall and three groove side walls, and the groove bottom wall is opposite to the rear shell 200; the mounting groove 313 has no groove side wall on the side corresponding to the first sound outlet 302, which not only makes the structure of the box shell 310 simple, but also facilitates processing.

[0108] Regarding the structure in which a sound outlet is arranged on the side wall of the installation groove 313, due to the limited size of the side wall and high processing accuracy requirements, the processing difficulty and cost of the box shell are high; and in order to facilitate the processing of the sound outlet on the side wall, part of the side wall is thickened to obtain sufficient processing space for the sound outlet, which is contrary to the original design intention of the thin speaker in some embodiments of the present application.

[0109] In some embodiments of the present application, a mounting groove 313 is provided in the box shell 310 to accommodate a portion of the thickness of the first speaker 320; and an elastic first sound guide member 400 is provided between the box shell 310 and the rear shell 200 to accommodate a portion of the thickness of the first speaker 320, without reserving a separate thickness interval for the first speaker 320; and the rear shell 200 is used as a sound guide structure for sound waves to achieve side sound output while further reducing the thickness of the speaker box to adapt to the limited rear space of the display device 10.

[0110] Furthermore, some embodiments of the present application utilize the first sound guide member 400 to form the first sound outlet 302, and utilize the installation groove 313 to omit part of the groove side wall, thereby increasing the sound output area of ​​the first sound outlet 302 and improving the sound output effect; moreover, it is helpful to increase the area of ​​the installation groove 313, thereby increasing the installation space of the speaker and improving the convenience of speaker installation.

[0111] The first sound guide 400 of some embodiments of the present application is elastic, so that the box shell 310 and the rear shell 200 are elastically connected, and the thickness of the first sound cavity 301 in the front and rear directions of the display device can be elastically enlarged or reduced, so as to absorb part of the sound wave energy on the rear shell 200, reduce the vibration force of the rear shell 200, and ensure the stability of the connection structure of the rear shell 200; it is beneficial to reduce the possibility of noise generated by the vibration of the rear shell 200, and ensure the acoustic effect. Moreover, the first sound guide 400 keeps the other positions between the box shell 310 and the rear shell 200 except the first sound outlet 302 closed at all times, that is, the first sound guide 400 plays a sealing role, reduces the possibility of sound leakage from the first sound cavity 301, and tries to make the sound waves concentratedly transmitted from the first sound outlet 302, further improving the sound effect.

[0112] Refer again Figure 4 In some embodiments of the present application, the display device further includes a side frame 250, and the side frame 250 is connected to the edge between the rear housing 200 and the display module 100. The side frame 250 is provided with a sound outlet 251.

[0113] The first sound cavity 301 , the first sound outlet 302 , and the sound outlet hole 251 form a sound outlet channel, and the sound waves generated by the first speaker 320 are transmitted to the outside of the display device through the sound outlet channel.

[0114] The shape of the side frame 250 is the same as that of the display device, and the side frame 250 is formed by a bottom side, a top side, a left side, and a right side. When the sound outlet 251 is arranged at the bottom side of the side frame 250, the sound is emitted from the bottom side of the display device, such as the center channel of the display device; when the sound outlet 251 is arranged at the top side of the side frame 250, the sound is emitted from the top side of the display device, such as the sky sound channel of the display device; when the sound outlet 251 is arranged at the left side of the side frame 250, the sound is emitted from the left side of the display device, such as the left channel and surround channel of the display device; when the sound outlet 251 is arranged at the right side of the side frame 250, the sound is emitted from the right side of the display device, such as the right channel and surround channel of the display device.

[0115] In some embodiments, the side frame 250 and the rear shell 200 are two independent components, so that the side frame 250 and the rear shell 200 can be processed separately, and the processing method is simple.

[0116] In some other embodiments, the side frame 250 and the rear case 200 are an integral part, that is, the circumferential edge of the rear case 200 bends and extends towards the display module 100 to form the side frame 250. In this way, the side frame 250 can be directly formed by the integral molding of the rear case 200, reducing the assembly process of the side frame 250 and improving the assembly efficiency.

[0117] Combined with Figure 7 , in some embodiments, the first sound guiding member 400 is a closed ring, and the surface of the first sound guiding member 400 facing the box shell 310 is recessed towards the rear case 200 to form a notch 402; the notch 402 communicates with the first sound cavity 301 to form at least part of the first sound outlet 302. With such a setting, the first sound guiding member 400 is a closed ring, with relatively high structural stability, which is convenient for the installation of the first sound guiding member 400.

[0118] When an installation groove 313 is provided on the box shell 310, the notch 402 is opposite to the second opening of the installation groove 313, and a part of the first sound guiding member 400 is opposite to the installation groove 313. The notch 402 and the second opening of the installation groove 313 together form the first sound outlet 302.

[0119] In some embodiments, the first sound guiding member 400 includes multiple sound guiding strips, and the multiple sound guiding strips are spliced to form the first sound guiding member 400, which is arranged around the outside of the first speaker 320. With such a setting, the installation of the first sound guiding member 400 is simple, and foam strips, sponge strips, etc. in related technologies can be used, without the need for special shape design and processing.

[0120] For the first sound guiding member 400 with a break 401 formed, it can be formed without setting a sound guiding strip; for the first sound guiding member 400 with a notch 402 formed, the sound guiding strip at the corresponding position has a smaller thickness to form the notch 402.

[0121] As shown in Figure 5 and Figure 6 , the shape of the first sound cavity 301 is an open rectangle, and the first sound guiding member 400 is generally in a "C" shape, with a first sound outlet 302 formed on one side. Such a regular shape is convenient for installation and design.

[0122] In some embodiments, combined again with Figure 5 and Figure 6 , the inner side surface of the first sound guiding member 400 facing the first sound cavity 301 is a plane. In this way, the structure of the first sound guiding member 400 is regular and simple, which is convenient for being formed by splicing strip-shaped sound guiding segments.

[0123] In some other embodiments, at least a portion of the inner side surface of the first sound guide 400 facing the first sound cavity 301 is a curved surface, such as an arc surface. This configuration makes at least a portion of the inner side surface of the first sound cavity 301 a curved surface, which can reduce vertical reflections of sound waves, thereby reducing peaks and valleys of sound waves, and helping to improve the smoothness of the sound waves.

[0124] In some embodiments, the inner side surface of the first sound guide 400 opposite to the first sound outlet 302 is a curved surface.

[0125] In some implementations, again referring to Figure 4 The first sound guide 400 is connected to the rear shell 200. For example, the first sound guide 400 is connected before the rear shell 200 is assembled, so there is sufficient operating space and high connection efficiency. Moreover, when the rear shell 200 is disassembled to maintain the internal structure of the display device, since the first sound guide 400 is located on the rear shell 200, the damage to the first sound guide 400 caused by improper maintenance operation can be reduced.

[0126] Exemplarily, the first sound guide 400 is bonded to the rear housing 200, for example, the first sound guide 400 has its own adhesive backing, which is bonded to the rear housing 200; for another example, the first sound guide 400 is bonded to the rear housing 200 by double-sided tape, glue, etc. In this way, the connection method is stable and reliable, the operation space is sufficient, the efficiency is high, and it is also convenient for disassembly and replacement; moreover, during the assembly process of the display device, it is convenient to adjust the position of the first sound guide 400 to form a sound cavity volume with better sound quality effect.

[0127] In other implementations, the first sound guide member 400 is connected to the box shell 310. In this way, the first sound guide member 400 constitutes a part of the first sound box 300. In the assembly process of the display device, there is no need to add an additional connection process of the first sound guide member 400, thereby ensuring the assembly process of the display device.

[0128] Exemplarily, the first sound guide member 400 is bonded to the box shell 310. With this arrangement, the connection method is stable and reliable, the operation is simple and efficient, and it is also convenient for disassembly and replacement; and the first sound guide member 400 is bonded to the box shell 310 to form a part of the sound box. During the assembly of the entire display device, there is no need for additional positioning and bonding operations of the first sound guide member 400 on the rear shell 200, which is beneficial to improving the assembly efficiency of the entire machine; and, the first sound guide member 400 is bonded to the box shell 310 in a more accurate position, which is convenient for forming a set sound cavity area, and is beneficial to reducing the possibility of affecting the sound cavity volume due to the position offset of the first sound guide member 400.

[0129] In some embodiments, the first sound guide member 400 is installed as a whole on the box shell 310, or the first sound guide member 400 is installed as a whole on the rear shell 200, and the installation method is relatively simple.

[0130] In other embodiments, part of the first sound guide member 400 is connected to the box shell 310, and the other part of the first sound guide member 400 is connected to the rear shell 200. Exemplarily, when the first sound guide member 400 includes multiple sections of sound guide strips, part of the sound guide strips are connected to the box shell 310, and part of the sound guide strips are connected to the rear shell 200. Such a configuration makes the connection method of the first sound guide member 400 flexible, which is convenient for flexible operation when assembling the display device.

[0131] For example, when part of the first sound guide component 400 connected to the rear shell 200 is damaged or fails due to improper transportation or the like, part of the sound guide strip connected to the rear shell 200 can be used to form the first sound guide component 400 together with the sound guide strip on the rear shell 200, thereby eliminating the need to return the entire first speaker 300 to the factory for repair, thereby improving production efficiency.

[0132] In some embodiments, the first sound guide member 400 is clamped between the box shell 310 and the rear shell 200, so that the first sound guide member 400 is compressed between the box shell 310 and the rear shell 200. This eliminates the need to add a connection process for the first sound guide member 400, thereby improving production efficiency.

[0133] When installed in this way, the position of the first sound guide 400 is easy to move and needs to be adjusted repeatedly. To this end, in some embodiments, a limiting portion that cooperates with the first sound guide 400 is provided on the box shell 310 to limit the position of the first sound guide 400. The limiting portion can be a groove, a convex hull or a convex point provided on the box shell 310, so that while limiting the position of the first sound guide 400, it is also beneficial to improve the structural strength of the box shell 310.

[0134] Recombination Figure 5 and Figure 6 The first sound guide 400 enables an elastic connection between the box shell 310 and the rear shell 200. Thus, when the rear shell 200 is subjected to vibrating sound waves, the first sound guide 400 is deformed by the vibration force and absorbs the vibration force, thereby avoiding noise generated by the rigid contact between the rear shell 200 and the box shell 310.

[0135] In some implementations, at least a portion of the first sound guide 400 is elastic. The first sound guide 400 includes an elastic portion. The elastic portion contacts the box shell 310 or the rear shell 200, so that the box shell 310 and the rear shell 200 are elastically connected.

[0136] In other implementations, the first sound guide 400 is an elastic member, for example, the first sound guide 400 is an elastic rubber member, foam, sponge, etc. In this way, the first sound guide 400 is an integrated member, which not only has better sealing performance and reduces the possibility of sound leakage in the sound cavity; but also has sufficient elastic deformation force to ensure the elastic connection between the box shell 310 and the rear shell 200; in addition, the elastic member structure of the related technology can be used, without additional processing and design, and the structure is simple.

[0137] Continue to refer to Figure 5 and Figure 6 In some embodiments, a plurality of first speakers 320 may be provided, for example, two, three, four, etc. The plurality of first speakers 320 are arranged at intervals along the length direction of the first sound outlet 302, and the plurality of first speakers 320 are all arranged in the same first sound cavity 301. In this way, the first sound guide 400 is arranged around the outside of all the first speakers 320, and the plurality of first speakers 320 may share a first sound outlet 302, so that the sound waves are concentrated and transmitted from the first sound outlet 302, thereby improving the acoustic effect; and a plurality of speakers may be arranged in a limited space, thereby improving the sound effect.

[0138] In some embodiments, in combination Figure 8 There are multiple first speakers 320, and there are multiple first sound cavities 301, wherein at least one first speaker 320 is independently arranged in one first sound cavity 301. The sound outlets of the multiple first sound cavities 301 are all located on the same side of the box shell 310, which is conducive to ensuring the directionality of the sound.

[0139] In some embodiments, each first speaker 320 is disposed in a first sound cavity 301 , respectively, so as to reduce interference between different speakers.

[0140] Compared with setting a larger first sound cavity 301 to accommodate all the first speakers, the above-mentioned setting of multiple smaller first sound cavities 301 increases the supporting position of the first sound guide 400, ensures the elastic connection between the rear shell 200 and the box shell 310, and reduces the rigid contact between the rear shell 200 and the box shell 310 caused by insufficient elastic support effect of the first sound guide 400 to generate noise.

[0141] Continue to refer to Figure 6 In some embodiments, the first sound box 300 further includes a second speaker 330 , which is mounted on the box shell 310 and is located in the first sound cavity 301 .

[0142] In some embodiments, the size of the mounting groove 313 is relatively large, so that the second speaker 330 can share a mounting groove 313 with the first speaker 320 . Such a configuration helps to simplify the structure of the box shell 310 .

[0143] In other embodiments, a plurality of mounting grooves 313 may be provided, and the second speaker 330 and the first speaker 320 are respectively installed in the mounting grooves 313 . In this way, the size of the mounting grooves 313 is relatively small, which is beneficial to ensuring the structural strength of the box shell 310 .

[0144] In some embodiments, at least some of the sound wave frequencies of the second speaker 330 are different from the sound wave frequencies of the first speaker 320. For example, some of the sound wave frequencies of the second speaker 330 are greater than the sound wave frequencies of the first speaker 320.

[0145] For example, the second speaker 330 may be a tweeter, and the sound wave frequency range of the second speaker 330 may be 2KHz to 20KHz. The first speaker 320 may be a midrange speaker, and the sound wave frequency range of the first speaker 320 may be 200Hz to 8KHz, or 200Hz to 10KHz.

[0146] In some embodiments, the frequency of the sound waves of the second speaker 330 is greater than the frequency of the sound waves of the first speaker 320 .

[0147] The speaker of the first sound box 300 in some embodiments of the present application improves the acoustic effect of the display device by coordinating the mid-range and the treble.

[0148] In some embodiments, no sound guide is provided on the outer side of the second speaker 330. When the first speaker 320 is a full-range speaker and the second speaker 330 is a tweeter, the two are installed close to each other and there is not enough space to provide a sound guide, so that the second speaker 330 and the first speaker 320 share a sound cavity, which is conducive to simplifying the sound box structure.

[0149] In some embodiments, the display device 10 further includes a second sound guide 500, which is located in the first sound cavity 301 and contacts the rear shell 200 and the box shell 310 respectively; the second sound guide 500, the rear shell 200 and the box shell 310 together enclose the second sound cavity 501, and the second sound guide 500 forms a second sound outlet 502 on one side of the first sound outlet 302. The second speaker 330 is located in the second sound cavity 501.

[0150] In this embodiment, a second sound cavity 501 is formed by setting a second sound guide 500 in the first sound cavity 301 to install a second speaker 330. In this way, the second sound cavity 501 can be used to separate the second speaker 330 and the first speaker 320, and the possibility of resonance between the two in the first sound cavity 301 to generate noise can be reduced. The sound output direction of the second speaker 330 is the same as that of the first speaker 320, and the sound waves can be mixed and transmitted at the same time, thereby ensuring the acoustic effect of the display device.

[0151] The structure, connection method, etc. of the second sound guide component 500 may refer to the first sound guide component 400 .

[0152] In some embodiments of the present application, the second sound guide 500 is provided so that the second speaker 330 and the first speaker 320 are located in different sound cavities, thereby reducing interference between different speakers and improving sound effects.

[0153] like Figure 5 and Figure 6 As shown, in some embodiments, a plurality of first speakers 320 are provided; one second speaker 330 may be provided, and the second speaker 330 may be provided between two adjacent first speakers 320. Exemplarily, two first speakers 320 are provided, and the second speaker 330 is provided between the two first speakers 320, and the two first speakers 320 are arranged symmetrically about the second speaker 330, and such a configuration is conducive to improving the appearance characteristics of the first sound box 300.

[0154] like Figure 8 As shown, in some embodiments, a plurality of first speakers 320 are provided, and the second speaker 330 is provided at the end of the plurality of first speakers 320. When the first speaker box 300 is installed on the top side or the bottom side of the display device, such a configuration facilitates the arrangement of speakers with higher frequencies on the side away from the vertical center line of the display device, which is beneficial to improving the stereo effect of the display device and increasing the width of the sound field.

[0155] In some embodiments, two first speakers 320 and one second speaker 330 are combined to form a sound unit 303, and the sound unit 303 is arranged in the same first sound cavity 301. Such an arrangement can make it possible to improve the sound performance, power, etc. of the first speaker 320 when the first sound box 300 is thinner, so the two first speakers 320 are matched with one second speaker 330 to improve the sound performance such as bandwidth and sound loudness, and improve the acoustic effect.

[0156] Reference Figure 8 In some embodiments, a plurality of first speakers 320 are provided in the first sound box 300, and a plurality of second speakers 330 are provided; the plurality of first speakers 320 are arranged at intervals along the length direction of the box shell 310, and the plurality of second speakers 330 are arranged at intervals along the length direction of the box shell 310, so as to increase the bandwidth and improve acoustic performance such as sound loudness.

[0157] exist Figure 8 In the structure shown, the first sound box 300 has two speakers, and the two first sound boxes 300 include different numbers of speakers. Those skilled in the art can set the number of speakers in the first sound box 300 according to the actual layout space, acoustic requirements, etc. In some possible implementations, Figure 8 The structure shown can be used as a surround channel speaker for a display device.

[0158] In some possible implementations, the plurality of first speakers 320 are evenly spaced apart along the length direction of the housing 310 to enhance the surround effect of the sound emitted by the display device.

[0159] When the first sound box 300 has multiple sound units 303 , the second speaker 330 can have various positions in the sound unit 303 . For example, the second speaker 330 can be arranged between two first speakers 320 . For another example, the second speaker 330 can be arranged at the end of the sound unit 303 .

[0163] There is no need to set a sound guide outside the third speaker 340. The third speaker 340 is a bass speaker and has low requirements on the directivity of sound waves.

[0164] In the description of some of the above embodiments, the third speaker 340 may be provided in the first sound box 300, and the third speaker 340 is configured to emit bass, so that the first sound box 300 has bass characteristics. That is, the bass speaker is integrated into the sound box with mid-high frequencies.

[0165] In some embodiments, the display device may also be equipped with a separate speaker that emits bass. Fig. 9 and Fig.10 As shown, in some embodiments, the display device 10 includes a bass speaker 600 , which is configured to emit low-frequency sounds.

[0172] The bass speaker 620 further includes a spring 625 , one end of which is connected to the bracket 622 , and the other end of which is connected to the second cone 624 .

[0173] In some embodiments, one or more woofers 620 may be provided. The number of woofers 620 is not only related to the speaker power, but also matches the net volume of the sound box. When the net volume of the woofer sound box 600 is large, multiple woofers 620 may be arranged to improve the loudness of the sound box; when the net volume of the woofer sound box 600 is small, one woofer 620 may be arranged to ensure low-frequency sound. The net volume of the sound box is the volume of the sound box minus the space occupied by all components in the sound box.

[0174] like Fig.10 and Fig.11 As shown, the bass speaker box 600 includes a box body 610 , which is configured to form a bass sound chamber 601 for installing and accommodating a bass speaker 620 and providing an installation position.

[0176] In some embodiments, in combination Fig. 9 The first shell 611 is the front shell of the box body 610, which is close to the back plate of the display device. The first shell 611 can be elastically installed on the back plate, and its installation method can refer to the box shell 310, which will not be repeated here.

[0177] In some embodiments, the first shell 611 includes a first plate body 6111 and a first side wall 6112 disposed on the first plate body 6111 . The first side wall 6112 is located on a side of the first plate body 6111 facing the second shell 612 , and the first side wall 6112 is located at an edge of the first plate body 6111 .

[0179] There are multiple first ribs 6113 , and the multiple first ribs 6113 can be arranged at intervals along a certain direction. In some embodiments, the multiple first ribs 6113 are cross-arranged to form a grid structure, which is beneficial to further improve the structural strength of the first shell 611 .

[0180] When the first rib 6113 is provided on the first plate body 6111 , the first rib 6113 is lower than the height of the first side surrounding wall 6112 , so as to avoid the first rib 6113 interfering with or rigidly contacting with the second shell 612 to generate abnormal noise.

[0181] In some embodiments, the first plate 6111 is provided with an escape groove 6115, which is recessed toward the bass cavity 601 to avoid the internal structure of the display device. The escape groove 6115 can also improve the structural strength of the first plate 6111.

[0182] In some embodiments, in combination Fig. 9 and Fig.12 The second shell 612 serves as a rear shell of the box body 610 , which is close to the rear shell 200 of the display device.

[0183] In some embodiments, a vibration damping member 630 is disposed between the second shell 612 and the rear shell 200 to reduce vibration transmitted from the bass speaker 600 to the rear shell 200 .

[0184] The vibration damper 630 can be bonded to the second shell 612 or the rear shell 200, and the connection method is simple and reliable. Alternatively, the vibration damper 630 is sandwiched between the second shell 612 and the rear shell 200, and there is no need to set up an additional connection structure of the vibration damper 630.

[0185] For example, the vibration damping member 630 may be sponge, foam, or the like.

[0186] In some embodiments, the vibration damper 630 is annular and is disposed around the outside of the woofer 620. In some embodiments, the vibration damper 630 is disposed at the edge of the second shell 612 so that the middle area of ​​the vibration damper 630 can be exposed to the outside of the rear shell 200.

[0187] In some embodiments, the second shell 612 includes a second plate 6121 and a second side wall 6122 disposed on the second plate 6121 . The second side wall 6122 is located on a side of the second plate 6121 facing the second shell 612 , and the second side wall 6122 is located at an edge of the second plate 6121 .

[0188] In some embodiments, the second shell 612 includes a second rib 6123, which can be arranged on the second plate body 6121, or the second rib 6123 is arranged on the second side wall 6122, or the second rib 6123 is arranged on both the second plate body 6121 and the second side wall 6122 to improve the structural strength of the second shell 612.

[0189] There are multiple second ribs 6123 , and the multiple second ribs 6123 can be arranged at intervals along a certain direction. In some embodiments, the multiple second ribs 6123 are cross-arranged to form a grid structure, which is beneficial to further improve the structural strength of the second shell 612 .

[0190] When the second rib 6123 is provided on the second plate body 6121 , the second rib 6123 is lower than the height of the second side surrounding wall 6122 , so as to avoid the second rib 6123 interfering with the first shell 611 or rigidly contacting with the first shell 611 to generate abnormal noise.

[0191] In some embodiments, the edge of the second plate 6121 is recessed away from the rear shell 200 toward the first shell 611 to form a recessed portion 6124. The recessed portion 6124 is convex on the side facing the first shell 611. A vibration damper 630 is provided between the recessed portion 6124 and the rear shell 200. In this way, the vibration damper 630 can be accommodated in the recessed portion 6124, and the thickness of the vibration damper 630 overlaps with at least part of the thickness of the second shell 612, and the provision of the vibration damper 630 does not increase the thickness of the bass speaker 600.

[0192] In some embodiments of the present application, the first shell 611 and the second shell 612 are fixedly connected by screws, and the connection method is stable and reliable.

[0193] Combination Fig. 9 and Fig.12 In some embodiments, a first connecting column 6114 is provided on the first plate 6111 of the first shell 611, and a first connecting hole is provided on the first connecting column 6114; a second connecting column 6125 is provided on the second plate 6121 of the second shell 612, and a second connecting hole is provided on the second connecting column 6125. One of the first connecting hole and the second connecting hole is a through hole, for example, the first connecting hole is a through hole that passes through the first plate 6111 and the first connecting column 6114. In this way, the screw passes through the first connecting hole and the second connecting hole, so that the first shell 611 and the second shell 612 are fixedly connected.

[0194] In addition, the provision of the first connecting column 6114 is beneficial to improving the structural strength of the first shell 611. The provision of the second connecting column 6125 is beneficial to improving the structural strength of the second shell 612.

[0195] In some embodiments, a plurality of first connection pillars 6114 may be provided, which is beneficial to further improve the structural strength of the first shell 611. The plurality of first connection pillars 6114 may be arranged in a rectangular matrix on the first plate 6111, with regular arrangement and stable structure.

[0196] In some embodiments, a plurality of second connecting pillars 6125 may be provided, which is beneficial to further improve the structural strength of the second shell 612. The plurality of second connecting pillars 6125 may be arranged in a rectangular matrix on the second plate 6121, with regular arrangement and stable structure.

[0197] In some embodiments, at least part of the first connecting column 6114 and at least the second connecting column 6125 are coaxially arranged, and the first connecting column 6114 and the second connecting column 6125 are connected by fasteners such as screws to achieve a fixed connection between the first shell 611 and the second shell 612.

[0198] In some embodiments, the number of first connecting columns 6114 is not equal to the number of second connecting columns 6125. The extra first connecting columns 6114 or second connecting columns 6125 can serve to increase the strength and provide installation locations for other components.

[0199] Exemplarily, when the thickness of the second plate body 6121 is relatively small, the number of the second connecting pillars 6125 may be greater than the number of the first connecting pillars 6114 , which is beneficial to improving the structural strength of the second shell 612 .

[0200] Exemplarily, the number of the second connecting columns 6125 is greater than the number of the first connecting columns 6114 , and the second connecting columns 6125 provide installation positions for the woofer 620 , which helps to simplify the structure of the second shell 612 .

[0201] In some embodiments, one of the first connecting column 6114 and the second connecting column 6125 is provided with a positioning groove, and the other of the first connecting column 6114 and the second connecting column 6125 cooperates with the positioning groove to provide initial positioning for the connection between the first connecting column 6114 and the second connecting column 6125, thereby improving the assembly efficiency of the first shell 611 and the second shell 612.

[0202] Exemplarily, a positioning groove is formed at the end of the first connecting column 6114 facing away from the first plate body 6111 , and the second connecting column 6125 cooperates with the positioning groove to provide initial positioning for the connection between the first connecting column 6114 and the second connecting column 6125 .

[0203] In some embodiments, a positioning portion is provided on one of the first shell 611 and the second shell 612, and a matching portion is provided on the other of the first shell 611 and the second shell 612. The positioning portion and the matching portion cooperate with each other to provide initial positioning for the fixed connection between the first shell 611 and the second shell 612, thereby improving the assembly efficiency of the first shell 611 and the second shell 612.

[0204] When the positioning portion is a groove, the matching portion is a protrusion matching the groove; when the positioning portion is a protrusion, the matching portion is a groove matching the protrusion.

[0205] In some embodiments of the present application, a positioning portion is provided on the first side wall 6112, and a matching portion is provided on the second side wall 6122, which can not only provide initial positioning for the fixed connection between the first shell 611 and the second shell 612, but also avoid the influence of the positioning portion and the matching portion on the net volume of the bass cavity 601.

[0206] In some embodiments, the bass speaker 620 is installed in the bass sound chamber 601 formed by the first shell 611 and the second shell 612 .

[0207] Exemplarily, the woofer speaker 620 may be fixedly connected to the first shell 611 , for example, the woofer speaker 620 is fixedly connected to the first connecting column 6114 , and the connection method is stable and reliable, and also makes the structure of the first shell 611 simple.

[0208] Exemplarily, the woofer speaker 620 is fixedly connected to the second shell 612 , for example, the woofer speaker 620 is fixedly connected to the second connecting column 6125 .

[0209] In some embodiments of the present application, the woofer speaker 620 is mounted on the second shell 612. This arrangement facilitates the position adjustment of the cone of the woofer speaker 620 and the through hole of the second shell 612, which is conducive to improving the convenience of the matching connection between the cone and the second shell 612, and is also conducive to improving the accuracy of the relative position of the outer cover of the woofer speaker 620 and the second shell 612, making the installation position adjustment of the woofer speaker 620 more flexible.

[0210] In the related art, the box body 610 is mostly made of plastic material. When the strength of the box body 610 is insufficient, it is easy to deform, lose the sound wave energy, and easily resonate with the sound wave to produce noise.

[0211] In some embodiments, the box 610 improves the structural strength by increasing the wall thickness, but ignores the thin design of the speaker.

[0212] In some embodiments, the box body 610 improves its structural strength by adding the above-mentioned ribs, connecting columns, etc., but this makes the molding mold structure of the box body 610 complex.

[0213] In some embodiments, at least a portion of the box body 610 is a metal plate portion, which is helpful to improve the structural strength of the box body 610 and reduce the deformation of the box body 610.

[0214] Exemplarily, at least part of the first shell 611 is a metal plate portion, for example, at least part of the first plate body 6111 of the first shell 611 is a metal plate portion, and for another example, at least part of the first side wall 6112 of the first shell 611 is a metal plate portion.

[0215] Exemplarily, at least part of the second shell 612 is a metal plate portion, for example, at least part of the second plate body 6121 of the second shell 612 is a metal plate portion, and for another example, at least part of the second side wall 6122 of the second shell 612 is a metal plate portion.

[0216] In some embodiments, the first shell 611 includes a metal plate portion and an injection molded plate portion, and the metal plate portion can be bonded to the injection molded plate portion, and the connection method is simple; or the metal plate portion is used as an insert during the injection molding of the injection molded plate portion, and is integrally formed with the injection molded plate portion, and the connection is stable and reliable. The injection molded plate portion can be a plastic plate portion.

[0217] In some embodiments, the second shell 612 includes a metal plate portion and an injection molded plate portion. The metal plate portion can be bonded to the injection molded plate portion, and the connection method is simple; or the metal plate portion is used as an insert during the injection molding of the injection molded plate portion, and is integrally formed with the injection molded plate portion, and the connection is stable and reliable. The injection molded plate portion can be a plastic plate portion.

[0218] In some embodiments, the box 610 is a metal box, which is beneficial to improve the structural strength and reduce the wall thickness of the box, thereby facilitating a thin design of the speaker.

[0219] Exemplarily, the first shell 611 is a metal shell, which can reduce the wall thickness of the first shell 611 and help reduce the overall thickness of the bass speaker 600.

[0220] Exemplarily, the second shell 612 is a metal shell, which can reduce the wall thickness of the second shell 612, thereby reducing the overall thickness of the bass speaker 600; and when at least part of the second shell 612 is exposed outside the rear shell 200, it is beneficial to improve the appearance of the display device.

[0221] In some embodiments, the woofer 620 is installed in an area of ​​the box 610 other than the metal plate portion. For example, the woofer 620 is installed in the injection molded plate portion. This arrangement facilitates the formation of connecting columns in other areas of the metal plate portion. The forming method of the connecting columns is simple, and the installation method of the woofer 620 is simple and reliable.

[0222] In some embodiments, the magnetic circuit structure of the woofer 620 contacts the metal plate portion, for example, the U-shaped magnetic yoke 627 of the woofer 620 contacts the metal plate portion to expand the heat dissipation area of ​​the woofer 620 and thereby improve the heat dissipation effect of the woofer 620 .

[0223] Combination Fig. 9 In some embodiments, the first shell 611 is provided with an opening 6110 connected to the bass cavity 601, so that at least part of the bass speaker 620 is exposed outside the box 610. Exemplarily, the bracket 622 of the bass speaker 620 is exposed outside the box 610 through the opening 6110, which is beneficial to improve the heat dissipation effect of the bass speaker 620.

[0224] In some embodiments, at least a portion of the bracket 622 is located in the opening 6110 , so that at least a portion of the bracket 622 is embedded in the opening 6110 , which can reduce the independent space required to be reserved for the bracket 622 , thereby helping to reduce the overall thickness of the bass speaker 600 .

[0225] In some embodiments, the second shell 612 is provided with a second sound outlet hole 6120 connected to the bass cavity 601, so that at least part of the bass speaker 620 is exposed outside the box 610. Exemplarily, the first cone 623 and the second cone 624 of the bass speaker 620 are exposed outside the box 610 through the sound outlet hole, so as to facilitate the propagation of sound waves outward.

[0226] In some embodiments, the first sound cone 623 and the second sound cone 624 are respectively arranged coaxially with the second sound outlet hole 6120, which is conducive to the outward propagation of sound waves and avoids the second shell 612 blocking the vibrating part of the sound cone and affecting the transmission of sound waves.

[0227] In some embodiments, the second sound outlet hole 6120 is coaxially arranged with the opening 6110 . Such an arrangement helps to simplify the installation of the woofer speaker 620 .

[0228] The amplitude and airflow of the woofer speaker 620 are usually relatively large, so there is a gap between the woofer speaker box 600 and the rear shell 200 of the display device to reduce the vibration force acting on the rear shell 200 and reduce the vibration of the rear shell 200.

[0229] However, the gap between the bass speaker 600 and the rear housing 200 makes the installation space of the bass speaker 600 relatively large, which is not conducive to the thin design of the display device and the bass speaker 600 thereof.

[0230] Combination Figure 10 to Figure 11 In some embodiments, the rear housing 200 is provided with a first sound outlet hole 240, so that at least a portion of the bass speaker 600 is exposed to the outside of the rear housing 200 through the first sound outlet hole 240. The second sound outlet hole 6120 of the bass speaker 600 is opposite to at least a portion of the first sound outlet hole 240, so that the sound waves can be transmitted to the outside through the first sound outlet hole 240.

[0231] Exemplary, combined Fig.13 The first cone 623 of the woofer speaker 620 is opposite to the first sound outlet hole 240 along the vibration direction. In this way, the first sound outlet hole 240 can be used to provide a vibration space for the first cone 623, reduce the gap between the woofer speaker 600 and the rear shell 200, and reduce the installation space occupied by the woofer speaker 600; and the first sound outlet hole 240 provided in the rear shell 200 is small in size, which is conducive to ensuring the structural strength of the rear shell 200. For example, the first sound outlet hole 240 is a circular hole.

[0232] Exemplary, combined Fig.14 At least part of the box 610 and the first and second cones 623 and 624 of the woofer 620 are opposite to the first sound outlet hole 240 along the vibration direction. This arrangement makes at least part of the second shell 612 of the box 610 exposed to the outside of the rear shell 200, which is convenient for sound wave transmission; moreover, the first sound outlet hole 240 on the rear shell 200 is large in size, which is conducive to saving materials for the rear shell 200 and reducing material costs. For example, the first sound outlet hole 240 is a rectangular hole with a simple structure and convenient processing.

[0233] The portion of the second shell 612 exposed outside the rear shell 200 may be provided with curved lines, etc., to improve the appearance of the display device. An inclined surface is provided near the edge of the second sound outlet hole 6120, and the lines provided on the inclined surface may be the same as the lines of the subsequent outer cover 621, which is conducive to improving the appearance of the display device.

[0234] Since the first sound outlet through hole 240 is provided on the rear housing 200 , the cone of the woofer speaker 620 is exposed, which is not only easy to be damaged, but also easy to accumulate dust.

[0235] In some embodiments of the present application, Fig.11 As shown, the woofer speaker 620 further includes an outer cover 621 , which serves as an appearance component or a decorative component of the woofer speaker 620 and is exposed outside the rear housing 200 .

[0236] The outer cover 621 is connected to the cone of the woofer speaker, and the outer cover 621 is opposite to at least a portion of the cone of the woofer speaker 620, so that the outer cover 621 can protect the cone and the outer cover 621 vibrates under the drive of the cone to radiate sound waves.

[0237] In some embodiments of the present application, the woofer 620 has a first cone 623 and a second cone 624, the outer cover 621 is connected to the first cone 623, and the outer cover 621 is connected to the connection between the first cone 623 and the second cone 624, the connection between the first cone 623 and the second cone 624 is relatively hard, which is conducive to improving the stability of the connection of the outer cover 621.

[0238] In some embodiments, a side of the outer cover 621 facing away from the sound basin is a convex curved surface structure, such as a convex arc surface, which has a larger surface area and is conducive to radiating sound waves.

[0239] In some embodiments, a CD pattern is provided on a side of the outer cover 621 facing away from the sound basin, which can not only improve the rigidity of the outer cover 621, but also reduce the deformation of the outer cover 621 itself when the sound basin vibrates, thereby reducing the effect on the sound characteristics.

[0240] The CD texture is a texture similar to a compact disk that is obtained by removing material from the side of the outer cover 621 away from the sound basin using a precision CD texture machine.

[0241] In some possible implementations, the outer cover 621 is circular, matching the shape of the cone of the woofer 620 , so as to better protect the cone and radiate sound waves.

[0242] In some embodiments, the outer cover 621 is bonded to the cone of the woofer 620. For example, in some embodiments of the present application, the outer cover 621 is bonded to the first cone 623, and the connection method is simple.

[0243] like Fig.15 As shown, the first sound basin 623 includes a folded ring 6231, an outer connecting edge 6232 and an inner connecting edge 6233, wherein the folded ring 6231 is U-shaped, with its inner side connected to the inner connecting edge 6233 and its outer side connected to the outer connecting edge 6232. The outer connecting edge 6232 fits with the bracket 622, and the inner connecting edge 6233 is connected to the second sound basin 624. The folded ring 6231 vibrates under the drive of the second sound basin 624.

[0244] The outer cover 621 is bonded to the inner connection edge 6233. Since the inner connection edge 6233 is connected to the second sound basin 624, the hardness is relatively large, which is conducive to ensuring the stability of the connection between the outer cover 621 and the first sound basin 623.

[0245] If the outer cover 621 is bonded to the fold ring 6231 , the connection stability of the outer cover 621 is poor because the fold ring 6231 is relatively soft.

[0246] If the outer cover 621 is connected to the outer connection edge 6232 , since the outer connection edge 6232 fits the bracket 622 and does not move, the outer cover 621 does not move, which will block the sound waves and affect the sound effect of the bass speaker 600 .

[0247] Continue to refer to Fig.15 The outer cover 621 includes a cover plate 6211 and a connecting portion 6212, the connecting portion 6212 is arranged on the side of the cover plate 6211 facing the cone of the woofer 620, and the connecting portion 6212 is connected to the first cone 623. The connecting portion 6212 is annular, so that the outer cover 621 matches the limited connection area of ​​the first cone 623.

[0248] like Fig.15 As shown, in some possible implementations, a convex pattern 6126 is provided on one side of the second shell 612 facing the first sound cone 623, and the convex pattern 6126 abuts against the outer connecting edge 6232 of the first sound cone 623. When the woofer 620 is fixed to the second shell 612, the outer connecting edge 6232 is pressed against the convex pattern 6126. The convex pattern 6126 is provided to facilitate positioning of the first sound cone 623 and the second shell 612, increase the friction between the outer connecting edge 6232 and the second shell 612, and reduce the possibility of movement between the first sound cone 623 and the second shell 612.

[0249] Combination Fig.13 In some embodiments, a first sound outlet hole 240 is provided on the rear shell 200 so that the outer cover 621 is exposed outside the rear shell 200 .

[0250] Combination Fig.11The outer cover 621 is located in the first sound outlet hole 240, and space is reserved for the vibration of the outer cover 621; and the outer cover 621 does not need to occupy space in the thickness direction of the display device alone, which is conducive to reducing the overall thickness of the bass speaker 600.

[0251] In some embodiments, the shape of the first sound outlet hole 240 is the same as the shape of the outer cover 621, so that the outer cover 621 can be exposed and the inner structure of the woofer 620 can be shielded and protected by the outer cover 621. Exemplarily, the first sound outlet hole 240 is circular.

[0252] In some embodiments, the diameter of the first sound outlet hole 240 is the same as the diameter of the outer cover 621 , so as to prevent the internal structure of the woofer speaker 620 from being exposed.

[0253] In some embodiments, the diameter of the first sound outlet hole 240 is larger than the diameter of the outer cover 621, so that there is a gap between the outer cover 621 and the hole wall of the first sound outlet hole 240, which can compensate for processing errors, assembly errors, etc., and improve the convenience of installation and matching between the outer cover 621 and the first sound outlet hole 240.

[0254] Exemplarily, the gap between the outer cover 621 and the hole wall of the first sound outlet through hole 240 may be 0.5 mm, which can compensate for processing errors, assembly errors, etc., and the gap is small and has little impact on the appearance.

[0255] Since the bonding area between the outer cover 621 and the first sound basin 623 is small, the connection between the outer cover 621 and the sound basin is unstable, and the outer cover 621 is easily debonded, causing it to fall off.

[0256] To this end, in some embodiments, in combination Fig.11 and Fig.15 The outer cover 621 is snap-fitted to the sound basin of the woofer 620, making the connection between the outer cover 621 and the sound basin more stable and reliable.

[0257] In some embodiments of the present application, the connection portion 6212 of the outer cover 621 is clamped with the inner connection edge 6233 of the first sound basin 623. The inner connection edge 6233 of the first sound basin 623 has a greater hardness, which is beneficial to improving the stability of the clamping of the connection portion 6212 and the inner connection edge 6233.

[0258] Combination Fig.15 In some embodiments, the inner connecting edge 6233 of the first sound basin 623 is provided with a sink 6234, and the connecting portion 6212 of the outer cover 621 is snap-fitted with the sink 6234, which has a simple structure and a reliable connection method.

[0259] The inner side of the inner connecting edge 6233 is formed with a sinking groove 6234, and the processing method is simple. Since the first sound basin 623 is elastic, the connection part 6212 and the sinking groove 6234 are connected by elastic deformation of the side wall of the sinking groove 6234.

[0260] In some embodiments, the connection portion 6212 is snap-fitted to the sink 6234 , and the connection portion 6212 is bonded to the bottom wall of the sink 6234 , further improving the stability and reliability of the connection between the outer cover 621 and the first sound basin 623 .
