Description

Technical Field

[0001] The present invention belongs to the field of audio-visual technology, and in particular relates to a television. Background Art

[0002] Today's market has increasingly higher requirements for televisions. While consumers pay attention to product quality, they also have to take into account multiple aspects such as picture quality, sound quality, and appearance. Ordinary TVs on the market often have three sound output methods: back speakers, bottom speakers, and front speakers. The back speakers output sound toward the back of the TV, so the sound quality is poor. The bottom speakers output sound toward the bottom of the TV, and the sound quality is slightly better than the back speakers, but the sound quality still needs to be improved. The front speakers have better sound quality than the first two because their sound output direction is facing the user. However, due to the speaker position and speaker installation requirements, the front speakers need to be designed with a wider decorative strip on the edge of the TV. This not only increases the cost of the TV, but also causes the width of the TV frame to be wider, which cannot meet the needs of most consumers for a "full-screen" viewing experience, thereby greatly narrowing the user range.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] It should be noted that when an element is referred to as being “fixed to” or “disposed on” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0041] It should also be noted that the directional terms such as left, right, up, and down in this embodiment are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0042] like Figures 1 to 3As shown, it is a relevant schematic diagram of a television 1 provided in an embodiment of the present invention. The television 1 includes a display module 10, a back panel 20, a frame assembly 30 and a tweeter vibrator module 40, wherein the display module 10 includes a liquid crystal glass 11, an optical film 12, a diffuser plate 14, and an LED light board 13 arranged in sequence from the outside to the inside.

[0043] The liquid crystal glass 11 is configured to face the user when in use. Normally, the side of the liquid crystal glass 11 facing the user is the front of the TV 1. The optical film 12 is provided on the side of the liquid crystal glass 11 facing away from the user. The LED light board 13 is provided on the side of the optical film 12 facing away from the user. The optical film 12 is used to adjust the light wave characteristics of the light waves emitted by the LED light board 13 to make the picture effect presented by the TV 1 better. The diffuser 14 is located between the optical film 12 and the LED light board 13. The diffuser 14 has certain optical characteristics such as haze, transmittance, and refractive index. It can convert point and line light sources into soft and uniform surface light sources, and can convert the dazzling high-brightness light source on the TV screen 1 into a soft, uniform and healthy light source. The user obtains a better viewing experience; the back panel 20 is located on the side of the LED light board 13 facing away from the user, and the frame assembly 30 is fixed relative to the back panel 20. The back panel 20 provides fixing and support for the display module 10 and the frame assembly 30. The back panel 20 can be made of metal materials such as steel and iron, and can also be made of materials such as plastic with higher strength; the frame assembly 30 is arranged around the LED light board 13 and can fix the liquid crystal glass 11, optical film 12, LED light board 13 and diffuser 14; the tweeter vibrator module 40 is arranged in the frame assembly 30, and the tweeter vibrator module 40 provides treble audio for the TV to improve the playback sound quality of the TV 1. Specifically, the tweeter vibrator module 40 can use a smaller tweeter audio integrated module.

[0044] The television set 1 provided by the present invention arranges a tweeter vibrator module 40 in the frame assembly 30, so that the television set 1 can realize frame sound output with better sound quality. Moreover, since the tweeter vibrator module 40 is small in size, the space required for its installation is also small, so that the width of the frame assembly 30 will not be too wide to affect the appearance of the television set 1, thereby simultaneously taking into account the consumer's "full-screen" immersive viewing visual experience requirements.

[0045] In some embodiments, the frame assembly 30 includes a bracket 31 and a middle frame 32. The bracket 31 is located inside the middle frame 32. Both the bracket 31 and the middle frame 32 can be fixed to the back panel 20 by screwing or gluing. The diffuser 14 and the optical film 12 are both supported by the bracket 31. The bracket 31 is arranged around the LED light board 13, enclosing the LED light board 13 inside. While limiting the position of the LED light board 13, the bracket 31 also plays a role in protecting the LED light board 13 to reduce the risk of damage to the LED light board 13. The middle frame 32 is arranged around the liquid crystal glass 11, the optical film 12, the LED light board 13, and the diffuser 14, that is, around the display module 10. In some embodiments, the middle frame 32 includes a top side frame 321, a left side frame 322 and a right side frame 323, that is, the middle frame 32 in this embodiment is a three-sided enclosure structure. The middle frame 32 can be an integrally molded structure or a split structure. The middle frame 32 is also the outermost appearance frame of the TV 1, which surrounds and covers the display module 10.

[0046] It should be noted that, in this embodiment, the sky side, ground side, left side and right side all refer to the television 1 in normal use. The sky side refers to the top side of the liquid crystal glass 11 of the television 1, the ground side refers to the bottom side of the liquid crystal glass 11 of the television 1, and the left side and right side refer to the left side and right side of the liquid crystal glass 11 when looking from the liquid crystal glass 11 to the back panel 20 (that is, from the front to the back of the television 1).

[0047] In some embodiments, the tweeter vibrator module 40 can be arranged on the inner side of the left side frame 322 of the middle frame 32, and of course, it can also be arranged on the inner side of the right side frame 323, both of which can achieve frame sound. Alternatively, a tweeter vibrator module 40 can be arranged on the inner side of the left side frame 322 and the inner side of the right side frame 323 at the same time. Compared with the prior art, the tweeter vibrator module 40 is arranged on the left and / or right side of the middle frame 32, which can ensure better sound effects while not increasing the width of the frame assembly 30, thereby taking into account both the "sound effects" and the appearance of the TV 1. Of course, in some other embodiments, the tweeter vibrator module 40 can also be arranged on the top side frame 321, which can also achieve the effect of frame sound.

[0048] See also Figure 3 、 Figure 4, a receiving groove 324 is provided on the inner side of the middle frame 32, and the tweeter vibrator module 40 is received in the receiving groove 324. By arranging the tweeter vibrator module 40 in the receiving groove 324, the space occupied by the tweeter vibrator module 40 can be further reduced, that is, the tweeter vibrator module 40 will not occupy too much extra space of the frame assembly 30, so that the frame width of the frame assembly 30 will not be too wide. Specifically, the tweeter vibrator module 40 can be attached to the receiving groove 324 by pasting, magnetic attraction, etc., or it can be fixed to the side wall of the receiving groove 324 by screws, etc., or the tweeter vibrator module 40 can be embedded in the groove by opening a groove in the receiving groove 324.

[0049] The tweeter module 40 has a connecting line 41 for electrical connection to realize functions such as power supply and communication.

[0050] In some embodiments, see also Figure 3 、 Figures 4 to 8 、 Figure 11 The bracket 31 is located between the diffuser 14 and the back panel 20. It can be made of aluminum. Aluminum has good thermal conductivity and can quickly transfer and dissipate the heat generated by the LED light board 13 in the TV, so that the temperature inside the TV will not be too high. The bracket 31 can support the optical film 12 and the diffuser 14. The bracket 31 is fixed to the back panel 20 by screws and other locking parts. Specifically, the bracket 31 includes a top-side bracket 311, a bottom-side bracket 312, and two side brackets 313. The two side brackets 313 are respectively located on the left and right sides of the LED light board 13 and are symmetrically arranged, that is, the top-side bracket 311, the bottom-side bracket 312, and the two side brackets 313 together form a frame shape. The bracket 31 and the middle frame 32 enclose a cavity 101. More specifically, the side bracket 313 is provided with a groove 3131, and the middle frame 32 A groove is also provided on the inside (not shown in the figure), and the side bracket 313 and the inner side wall of the middle frame 32 enclose the cavity 101. The connecting line 41 of the tweeter vibrator module 40 can be arranged in the cavity 101. A part of the connecting line 41 of the tweeter vibrator module 40 is accommodated in the cavity 101, and the other part passes through the outside of the cavity 101 and is passed through the back panel 20. The connecting line 41 passes through the back side of the back panel 20 and is placed in the back shell of the TV to realize a hidden wiring design.

[0051] In some embodiments, see Figure 3 、 Figure 8The television set 1 further includes a floor side strip 50 disposed outside the floor side bracket 312. The floor side strip 50 is used to secure the optical film 12. The floor side strip 50 is secured to the floor side bracket 312 using screws or other fasteners. A hook 51 is provided on the floor side strip 50, and a corresponding slot 3121 is provided on the floor side bracket 312 for mate with the hook 51. The engagement between the hook 51 on the floor side strip 50 and the slot 3121 on the floor side bracket 312 allows for quick alignment and pre-positioning of the floor side strip 50 and the floor side bracket 312 during assembly, thereby improving assembly efficiency. In this embodiment, the floor side strip 50 can also be secured to the floor side bracket 312 by gluing.

[0052] Furthermore, the floor side strip 50 has a roughly L-shaped cross-section, and a rib 53 is protruded from its inner side for positioning. The floor side bracket 312 is correspondingly provided with an anti-turnover groove 3122 that matches the rib 53. During assembly, the rib 53 is inserted into the anti-turnover groove 3122 for engagement. The engagement between the engaging groove 3121 and the hook 51, and the rib 53 and the anti-turnover groove 3122, stably secures the floor side strip 50 to the floor side bracket 312. The edge of the diffuser plate 14 abuts against the rib 53 of the floor side strip 50, and the diffuser plate 14 is restrained in position by the floor side strip 50, the optical film 12, and the bracket 31.

[0053] In some embodiments, the floor side strip 50 is provided with a first hanging ear 52 for securing the optical film 12. The first hanging ear 52 is part of the floor side strip 50, and the floor side of the optical film 12 is correspondingly provided with a first hanging hole 121 for inserting the first hanging ear 52. The interaction between the first hanging ear 52 and the first hanging hole 121 of the optical film 12 allows the optical film 12 to be fixed in place.

[0054] In some other embodiments, see also Figure 3 、 Figure 6 、 Figures 9 to 11The upper bracket 311 is also provided with a second hanging ear 60. The second hanging ear 60 can be an independent component, which can be a T-shaped structure and can be fixed to the upper bracket 311 by screws or other fasteners, or can be fixed to the upper bracket 311 by gluing or other methods. The upper bracket 311 is provided with an assembly positioning hole 3111 for fasteners such as screws. A second hanging hole 122 is provided on the upper side of the optical film 12, and the second hanging ear 60 is inserted into the second hanging hole 122. By respectively providing a first hanging ear 52 and a second hanging ear 60 on the lower side edge strip 50 and the upper side of the bracket 31, respectively, and plugging them into the first hanging hole 121 on the lower side and the second hanging hole 122 on the upper side of the optical film 12, the optical film 12 can be firmly positioned to prevent the optical film 12 from jumping out or scratching the liquid crystal glass 11. Of course, in some other embodiments, the second hanging ear 60 may also be integrally formed with the top-side bracket 311 , and can also achieve the function of limiting the optical film 12 .

[0055] In some embodiments, see also Figure 3 、 Figure 12 、 Figure 13 The television set 1 further includes a decorative strip 80, which is provided on the ground side of the frame assembly 30. The decorative strip 80 is spliced ​​with the frame assembly 30. More specifically, the decorative strip 80 is spliced ​​with the middle frame 32 of the frame assembly 30. The decorative strip 80 includes a bottom wall 801 and a side wall 802. The bottom wall 801 is spliced ​​with the middle frame 32 on three sides, that is, the bottom wall 801 of the decorative strip 80 and the top side frame 321, the left side frame 322 and the right side frame 323 together form a square frame structure with four sides, forming a four-sided frame integration. The structure forms the overall outer frame of the television 1. The bottom wall 801 can be made of aluminum to enhance the structural stability. The thickness of the bottom wall 801 can be the same as the width of the middle frame 32 to enhance the visual effect of "integration". The outer surface of the side wall 802 of the decorative strip 80 is flush with the side of the liquid crystal glass 11 facing the user, so that the side wall 802 of the decorative strip 80 can form a sense of integration with the liquid crystal glass 11, giving consumers a "frameless" visual experience. The side wall 802 can be made of black PC. Of course, the decorative strip 80 in this embodiment can also be made entirely of plastic material.

[0056] See also Figure 2 、 Figure 14 、 Figure 15In some embodiments, the television 1 further includes at least one speaker 90 fixedly mounted relative to the back panel 20, with the speaker 90 being positioned near the ground side of the back panel 20. In this embodiment, two speakers 90 are provided, and the two speakers 90 are symmetrically positioned on the ground side of the back panel 20. The closer the speakers 90 are to the ground side, the better the sound output effect. Since the speakers 90 are relatively large, positioning the speakers 90 near the ground side can avoid placing the speakers 90 near the left or right side of the television, which would cause the left or right side frame of the television to be too wide, thereby affecting the appearance and viewing experience. It can also avoid placing the speakers 90 too close to the tweeter module 40 on the left or right side, thereby affecting the sound quality. The two speakers 90 positioned on the ground side cooperate with the tweeter module 40 positioned on the left or right side to achieve complementary high and low frequencies, thereby further improving the playback sound quality of the television and providing users with a better viewing experience.

[0057] In some embodiments, the television 1 has a built-in telescopic bracket 91, which is fixed to the back panel 20 via an adapter plate 92. The telescopic bracket 91 expands the user's installation options. When wall-mounting is required, the telescopic bracket 91 can be extended, and when wall-mounting is not required, the telescopic bracket 91 can be retracted, allowing the user to selectively wall-mount the television 1 to meet different user needs. The specific structure of the telescopic bracket 91 can adopt a commercially available bracket structure.

[0058] In some other embodiments, the television 1 has a built-in camera module 93 so that the television 1 can realize the camera function. The camera module 93 can be installed and fixed on the back panel 20, specifically, it can be installed close to the sky side of the back panel 20 to facilitate shooting in a larger viewing angle range.

[0059] In some embodiments, see Figure 2 、 Figure 3 The television 1 further includes a decorative cover 81 disposed on the side of the back panel 20 facing away from the user. The decorative cover 81 is mounted on the back panel 20 and can form an integrated effect with the rear shell of the television 1 to enhance the appearance of the television.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
