Description

Technical Field

[0001] This application relates to the field of audio technology, and more particularly to an audio system. Background Technology

[0002] A soundbar is a stereo speaker system, typically placed above or below a display screen. For acoustic reasons, these speakers are often designed as long, narrow strips. Soundbars are generally designed as multi-channel systems, with multiple built-in speakers that bounce sound off the walls to simulate a stereo effect. Their advantage is that they are easy to install, eliminating the hassle of running wires like traditional speakers.

[0003] In related technologies, the assembly of soundbars requires both speaker installation and foam bonding to be performed on the housing, which cannot be done simultaneously, resulting in low assembly efficiency. Furthermore, the upward-facing speakers cannot be isolated from other speakers, affecting the sound output. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an audio system.

[0005] This application provides an audio device, including:

[0006] The housing has an open-front chamber inside, and multiple partitions are provided inside the chamber, which are spaced apart to divide the chamber into at least one first mounting cavity.

[0007] A fixed mounting component is provided to enclose the front side of the first mounting cavity, corresponding to the first mounting cavity.

[0008] A first speaker assembly is disposed within the first mounting cavity, and the first speaker assembly is mounted on the fixed mounting member facing the upper side wall of the housing;

[0009] A front mesh cover is provided at the front end of the housing to cover the opening of the housing.

[0010] The speaker provided in this application embodiment has a fixing bracket inside the housing. A first speaker assembly facing upwards is mounted via this fixing bracket. During speaker assembly, the first speaker assembly can be simultaneously mounted onto the fixing bracket, and instant noodles can be pasted inside the housing. These two processes can be performed concurrently, improving assembly efficiency. Furthermore, the fixing bracket isolates the first speaker assembly within an independently provided first mounting cavity, preventing interference with other speakers and improving the overall sound output of the speaker.

[0011] In some embodiments, the fixing component includes a first fixing part and a second fixing part. The first fixing part covers the front side of the first mounting cavity, and the second fixing part is located at the upper end of the first fixing part and is disposed opposite to the upper sidewall of the housing. The second fixing part has a first mounting opening, and the first speaker assembly is fixed at the first mounting opening. The upper sidewall of the housing has a second mounting opening at a position corresponding to the first mounting opening, and a mesh cover covers the outside of the second mounting opening. The first fixing part and the partition together enclose the mounting cavity of the first speaker assembly, isolating the first speaker assembly from other speakers of the speaker and improving the sound output effect. The second fixing part provides a mounting base for the first speaker assembly, preventing the first speaker assembly from being directly mounted on the upper sidewall of the housing, which would result in a large number of screws on the upper sidewall of the housing and affect the visual effect. The mesh cover does not affect the sound transmission of the first speaker assembly from the mesh cover, and at the same time, it can cover the mounting position of the first speaker assembly, avoid exposed screws, and improve the aesthetics of the upper sidewall of the speaker.

[0012] In some embodiments, the first fixing part is provided with a plurality of first fixing holes, and the housing is provided with a plurality of second fixing holes at corresponding positions. A first fastener passes through the first fixing holes and the second fixing holes in sequence to connect the first fixing part to the housing. Using the first fastener to connect the first fixing part to the housing improves the assembly stability of the fixing component and the housing, and facilitates the replacement of the fixing component.

[0013] In some embodiments, the lower surface of the second fixing part is provided with a plurality of third fixing holes, which are spaced apart around the first mounting opening along the circumference of the first mounting opening; a fourth fixing hole is provided at the corresponding position of the first horn assembly, and the second fastener passes through the fourth fixing hole and the third fixing hole in sequence to fix the first horn assembly to the second fixing part. Fixing the first horn assembly to the second fixing part with the second fastener avoids the aesthetic problem of too many screws on the upper sidewall of the housing, which would result from directly fixing the first horn assembly to the housing, and also facilitates the replacement of the first horn assembly.

[0014] In some embodiments, the front mesh cover includes a front cover portion and a side cover portion formed by bending rearward along the circumferential edge of the front cover portion. The front cover portion covers the front side of the housing, and the side cover portion extends from the front end of the housing into the cavity, and the side cover portion fits against the inner wall of the housing. The side cover portion is connected to the housing by a snap-fit ​​mechanism and a third fastener. The connection between the side cover portion and the housing by the snap-fit ​​mechanism and the third fastener reduces the amount of fasteners such as screws, reduces the screwing process during the installation of the front mesh cover and the housing, facilitates installation, and improves the appearance.

[0015] In some embodiments, the snap-fit ​​mechanism includes a first buckle on the side cover and a first snap-fit ​​hole on the housing. The first buckle protrudes upward on the outer surface of the side cover and then bends and extends towards the rear of the housing. The first snap-fit ​​hole penetrates the upper sidewall of the housing along the thickness direction, and the first buckle snaps into the first snap-fit ​​hole. When the front mesh cover is assembled with the housing, the first buckle passes through the upper sidewall of the housing from the inside of the first snap-fit ​​hole. The first buckle engages with the hole wall through the bent portion of the first buckle, achieving a snap-fit ​​between the first buckle and the first snap-fit ​​hole. This method is convenient to operate and provides a good snap-fit ​​effect.

[0016] In some embodiments, the upper surface of the housing is provided with a mounting groove, the projection of the first speaker assembly on the upper sidewall of the housing is located within the mounting groove, the second mounting port and the first snap-fit ​​hole are both formed within the mounting groove, and the mesh cover is embedded within the mounting groove to cover the second mounting port and the first snap-fit ​​hole, with the upper surface of the mesh cover flush with the upper surface of the housing. The upper surface of the mesh cover and the upper surface of the housing can be smoothly joined together, jointly forming the appearance surface of the upper sidewall of the soundbar, thereby maintaining the integrity and aesthetics of the soundbar's appearance and improving the overall appearance quality of the speaker.

[0017] In some embodiments, the rear sidewall of the first snap-fit ​​hole extends forward to form a snap-fit ​​arm. The upper surface of the snap-fit ​​arm is lower than the upper surface of the housing, so that when the first buckle engages with the snap-fit ​​arm, the end face of the first buckle away from the side cover is lower than or flush with the bottom of the mounting groove. After the first buckle passes through the first snap-fit ​​hole, it abuts against the upper surface of the snap-fit ​​arm, thereby realizing the snap-fit ​​between the first buckle and the snap-fit ​​arm, that is, the snap-fit ​​between the first buckle and the first snap-fit ​​hole. The purpose of setting the snap-fit ​​arm is that when the first buckle passes through the first snap-fit ​​hole to achieve snap-fit, the first buckle will not be higher than the bottom of the mounting groove. In this way, when the net cover is embedded in the mounting groove, the lower side of the net cover can be fitted against the bottom of the mounting groove without interfering with the first buckle, thus improving the compactness of the installation structure.

[0018] In some embodiments, the snap-fit ​​mechanism further includes a second snap-fit ​​and a first snap-fit ​​groove that engages with the second snap-fit. One of the second snap-fit ​​and the first snap-fit ​​groove is disposed on the side cover portion, and the other is disposed on the housing. There are multiple second snap-fits, which are spaced apart circumferentially along the side cover portion or the housing. By setting multiple sets of second snap-fits to engage with the first snap-fit ​​groove, different snap-fit ​​mechanisms can be set according to the structural characteristics of different positions of the front cover and the housing, which has a certain degree of flexibility.

[0019] And / or, the lower side cover portion is provided with a fifth fixing hole, and the corresponding position of the lower side wall of the housing is provided with a sixth fixing hole. The third fastener passes through the sixth fixing hole and the fifth fixing hole in sequence to fix the lower side cover portion to the lower side wall of the housing. By setting the third fastener between the lower side cover portion and the lower side wall of the housing to fix the front grille and the housing, the stability of the installation structure is improved, and the third fastener is hidden on the lower side of the speaker, improving the overall aesthetics of the speaker.

[0020] In some embodiments, a plurality of spaced reinforcing ribs are provided on the rear sidewall of the housing corresponding to the first mounting cavity. By providing reinforcing ribs on the rear sidewall of the housing, the irregularity of the first mounting cavity is increased, the generation of standing waves is reduced, and the sound output effect is optimized.

[0056] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0057] Figure 1 This is a schematic diagram of the overall structure of a display device according to an embodiment of the present invention.

[0058] Please see Figure 1 The display device provided in this embodiment mainly includes a display body 100 and a bar speaker 200. The speaker 200 is connected to the display device by signal, and is thus applied to a multi-channel audio system. It can ensure a good bass effect while also meeting the requirements of small size and lightweight design of the speaker 200, which makes it easier to place the speaker 200 more freely and is highly practical.

[0059] The display unit 100 includes a screen for displaying images and a built-in audio system, serving as an input / output playback device for video and audio. Therefore, the display unit 100 is not limited to televisions such as LCD TVs or plasma TVs, but also includes other audio input devices with screens, such as computers. The display unit 100 includes a control motherboard, and power interfaces and external device interfaces electrically connected to the control motherboard. The external device interface is used to connect external devices, thereby sending media data to the external devices.

[0060] The speakers 200 are placed horizontally and located at the bottom of the display unit 100. Of course, the speakers 200 can also be placed at intervals on the front side of the display unit 100, or they can be wall-mounted for playing music.

[0061] The speaker 200 serves as an external device with audio output capabilities. The speaker 200 can be connected to the external device interface of the display unit 100 via a cable using specific interface standards, such as HDMI or USB. For example, the speaker 200 can be connected to the display unit 100 via a USB interface. When the display unit 100 needs to output audio, it can send audio data to the speaker 200 via the USB interface, and the speaker 200 will then convert the audio data into a sound signal to achieve audio output.

[0062] Understandably, the speaker 200 can also wirelessly connect to the display unit 100 via its built-in Bluetooth or WIFI module.

[0063] In some embodiments, the speaker 200 can also perform audio quality processing on the audio transmitted by the display unit 100 to play the audio data according to a specific output method and obtain the corresponding sound quality effect. Therefore, users can control the data processing function through interactive actions, that is, set the output method. For example, the settings supported by the speaker 200 include sound effect mode, surround switch, treble adjustment, bass adjustment, display brightness adjustment, factory reset, etc.

[0064] In some embodiments of this application, the soundbar 200 has an upward-facing speaker inside, forming a sky channel.

[0065] In related technologies, soundbars typically employ a shell structure composed of an upper and lower casing assembled together. This assembly method requires the manufacture of relatively complex molds, resulting in high mold-making costs. When assembling the speakers in a soundbar, both speaker installation and speaker mounting must be performed on the casing, making simultaneous operations impossible. Furthermore, the upward-facing speakers cannot be isolated from the speakers in other channels, affecting sound quality.

[0066] To solve the above-mentioned technical problems, the soundbar provided in this application includes a housing 1, a first speaker assembly 9, a partition 3, a front grille 2, and a fixing mounting component 5.

[0067] In the soundbar 200 provided in this application embodiment, the interior of the housing 1 forms a forward-open chamber, and the front grille 2 is disposed at the front end of the housing to cover the opening of the housing 1.

[0068] The housing 1 of the soundbar is placed horizontally. For ease of description, it is referred to as... Figure 1 Based on the view direction, the direction facing the user is "front" of the housing 1, and the direction away from the user is "rear", and "up, down, left, right" are determined by the above orientation.

[0069] like Figures 2 to 15 As shown, the housing 1 can be made of PVC material by extrusion molding. The housing 1 has an upper side wall, a lower side wall, a rear side wall, a left side wall, and a right side wall. Multiple partitions 3 are present, dividing the chamber within the housing 1 into at least one first mounting cavity 101. Specifically, in some embodiments of this application, the partitions 3 divide the chamber within the housing 1 along their length into two first mounting cavities 101 and an intermediate mounting cavity. The two first mounting cavities 101 are located at the left and right ends of the intermediate mounting cavity. The number of intermediate mounting cavities can be determined based on the number of other speakers and electronic components that need to be arranged.

[0070] For example, such as Figure 5 As shown, in some embodiments of this application, there are three intermediate mounting cavities: a speaker mounting cavity 102 and an electronic control cavity 103. The two speaker mounting cavities 102 are located at the left and right ends of the electronic control cavity 103. That is, from left to right, the housing 1 contains a first mounting cavity 101, a speaker mounting cavity 102, an electronic control cavity 103, a speaker mounting cavity 102, and a first mounting cavity 101. The electronic control cavity 103 houses electronic components 8 such as a main control board, a power supply board, a terminal board, a power amplifier board, and a display board.

[0071] like Figure 11 and Figure 14As shown, a tweeter 6 is installed in the speaker mounting cavity 102. After the installation of the fixing mounting piece 5 is completed, there is an installation gap between the fixing mounting piece 5 and the front grille 2 bracket. The tweeter 6 is set in the installation gap and faces forward. The full-range speaker 7 and the tweeter 6 are both set facing the front grille 2 and fixed on the front grille 2. The full-range speaker 7 facing forward on the left end and the tweeter 6 in the adjacent speaker mounting cavity 102 together form the left front channel. The full-range speaker 7 facing forward on the right end and the tweeter 6 in the adjacent speaker mounting cavity 102 together form the right front channel.

[0072] The first speaker assembly 9 within the first mounting cavity 101 is a full-range speaker. The full-range speaker in the left end of the first mounting cavity 101 forms the left sky channel, and the full-range speaker in the right end of the first mounting cavity 101 forms the right sky channel. This can improve the sound effect and sound quality of the speaker.

[0073] Understandably, a subwoofer or woofer can also be installed inside the housing 1.

[0074] In this embodiment, the cross-section of the housing 1 is approximately square, and the various chambers within the housing 1 are also approximately square. It is understood that in other embodiments, the housing 1 may also employ other polygonal structures.

[0075] In some embodiments of this application, the fixing mounting member 5 is disposed in the cavity inside the housing 1 and is correspondingly disposed with the first mounting cavity 101 to close the front side of the first mounting cavity 101, thereby closing the first mounting cavity 101 into an independent space.

[0076] The first speaker assembly 9 is disposed within the first mounting cavity 101, and the first speaker assembly 9 is positioned facing the upper side wall of the housing 1. It can be understood that the sound output direction of the first speaker assembly 9 is towards the upper side wall of the housing 1. The first speaker assembly 9 is mounted on the fixed mounting member 5.

[0077] Since the first speaker assembly 9 is not directly assembled with the housing 1, there is no need to provide a fixing structure on the housing 1 for fixing the first speaker assembly 9. The free space on the housing 1 can be used for optimized design to improve the sound output. When assembling the soundbar 200, the process of installing the first speaker assembly 9 onto the fixing mounting piece 5 and the process of pasting foam can be carried out simultaneously without affecting each other, thus improving assembly efficiency. At the same time, the setting of the fixing mounting piece 5 encloses the first speaker assembly 9 in an independently set first mounting cavity 101, preventing mutual interference with other speakers (also known as loudspeakers) and improving the overall sound output of the soundbar 200.

[0078] like Figures 14 to 17As shown, in some embodiments of this application, the fixing component 5 includes a first fixing part 51 and a second fixing part 52, the first fixing part 51 and the second fixing part 52 are connected to each other, and the first fixing part 51 and the second fixing part 52 can be made by an integral molding process.

[0079] The first fixing part 51 covers the front side of the first mounting cavity 101 and is disposed opposite to the front grille 2. The second fixing part 52 is disposed at the upper end of the first fixing part 51 and is disposed opposite to the upper side wall of the housing 1. The second fixing part 52 is provided with a first mounting port 521. The first speaker assembly 9 is fixed at the first mounting port 521. The sound output part of the first speaker assembly 9 is disposed opposite to the first mounting port 521 and transmits sound through the first mounting port 521.

[0080] A second mounting port 11 is provided on the upper side wall of the housing 1 at a position corresponding to the first mounting port 521, and a mesh cover 10 is provided on the outside of the second mounting port 11.

[0081] In some embodiments of this application, both the second mounting port 11 and the first mounting port 521 are elliptical openings, and their projections on the mesh cover 10 at least partially overlap. It is understood that in other embodiments, the first mounting port 521 and the second mounting port 11 may also be circular, polygonal, or other shapes.

[0082] For example, in some embodiments of this application, the projections of the second mounting port 11 and the first mounting port 521 on the mesh cover 10 coincide, and the mesh cover 10 completely covers the second mounting port 11 and the first mounting port 521. The mesh cover 10 is provided with evenly arranged sound outlet holes, which on the one hand allows the sound emitted by the first speaker assembly 9 to be emitted upward along the first mounting port 521 and the second mounting port 11, and on the other hand, the mesh cover 10 can also block external dust and other impurities from entering the housing 1 and affecting the first speaker assembly 9.

[0083] The first fixing part 51 and the partition plate 3 together enclose the first mounting cavity 101 of the first speaker assembly 9, isolating the first speaker assembly 9 from other speakers in the speaker system and improving the sound output effect. The second fixing part 52 provides a mounting base for the first speaker assembly 9, preventing the first speaker assembly 9 from being directly mounted on the upper side wall of the housing 1, which would result in a large number of screws on the upper side wall of the housing 1 and affect the visual effect. The mesh cover 10 does not affect the sound transmission of the first speaker assembly 9 from the mesh cover 10, and at the same time, it can also cover the mounting position of the first speaker assembly 9 to avoid exposed screws, thus improving the aesthetics of the upper side wall of the speaker system.

[0084] In some embodiments, the first speaker assembly 9 includes a frame, a connecting plate, a diaphragm, and a drive magnet.

[0085] The outer contour of the basin stand is tapered, resulting in a large upper end and a small lower end. The basin stand is located inside the housing 1, with the large end facing upwards and toward the first mounting opening 521, and the small end extending downwards into the housing 1 and away from the first mounting opening 521.

[0086] The connecting plate extends radially outward from the edge of the larger end of the first speaker assembly 9. The connecting plate is used to connect to the periphery of the first mounting port 521, thereby fixing the first speaker assembly 9 at the first mounting port 521. The connecting plate is sealed to the periphery of the first mounting port 521, thereby ensuring the airtightness of the sound cavity.

[0087] The diaphragm, also known as a paper cone, is used to vibrate and produce sound. The diaphragm is located in the central area of ​​the first mounting port 521, thereby enabling the first speaker assembly 9 to emit sound upwards from the first mounting port 521.

[0088] The drive magnet is connected to the small end of the basin frame. The drive magnet is located inside the housing 1 and is used to drive the diaphragm to vibrate and produce sound.

[0089] In some embodiments of this application, the first fixing part 51 is provided with a plurality of first fixing holes 511, and the housing 1 is provided with a plurality of second fixing holes 15 at the corresponding positions. The first fastener passes through the first fixing holes 511 and the second fixing holes 15 in sequence to connect the first fixing part 51 to the housing 1.

[0090] For example, such as Figure 5 and Figure 6 As shown, the rear sidewall of the housing 1 protrudes forward to form multiple protruding structures. Second fixing holes 15 are provided on these protruding structures, and the second fixing holes 15 are arranged perpendicular to the rear sidewall of the housing 1. The lower sidewall of the protruding structures is connected to the lower sidewall of the housing 1. Similarly, protruding structures are formed on the outer side of the partition 3 that forms the first mounting cavity 101. These protruding structures are spaced apart in the vertical direction on the partition 3. When assembling the mounting component 5 with the housing 1, the mounting component 5 is placed correspondingly on the front side of the first mounting cavity 101, with the first fixing hole 511 aligned with the second fixing hole 15. A first fastener passes sequentially through the first fixing hole 511 and the second fixing hole 15 from the front side of the mounting component 5 to lock and fix the mounting component 5 to the housing 1.

[0091] Specifically, in some embodiments of this application, the first fixing hole 511 is a smooth hole, the second fixing hole 15 is a threaded hole, the first fastener is provided with an external thread, and the first fastener passes through the first fixing hole 511 and is screwed into the second fixing hole 15.

[0092] like Figure 17In some embodiments of this application, the lower surface of the second fixing part 52 is provided with a plurality of third fixing holes 522, and the plurality of third fixing holes 522 are spaced apart around the first mounting opening 521 along the circumference of the first mounting opening 521; the corresponding position of the first speaker assembly 9 is provided with a fourth fixing hole (not shown in the figure), and the second fastener passes through the fourth fixing hole and the third fixing hole 522 in sequence to fix the first speaker assembly 9 on the second fixing part 52.

[0093] For example, the fourth fixing hole is provided on the connecting plate, the lower surface of the second fixing part 52 protrudes downward to form a fixing post, and the fixing post is provided with a third fixing hole 522 along the axial direction. The third fixing hole 522 is a threaded hole, the fourth fixing hole is a smooth hole, the outer surface of the second fastener is provided with an external thread, and the second fastener passes through the fourth fixing hole from the bottom of the connecting plate and is screwed into the third fixing hole 522, thereby fixing the first speaker assembly 9 on the second fixing part 52.

[0094] In some embodiments of this application, the lower surface of the second fixing part 52 is inclined upwards in the direction from front to back, so that the sound output direction of the first speaker assembly 9 is upward and forward after installation. The front sidewall of the first mounting port 521 is inclined backwards in the direction close to the connecting plate, and the second mounting port 11 formed gradually narrows in the direction close to the connection, that is, the area of ​​the first mounting port 521 at the end close to the connecting plate is smaller than the area at the end away from the connecting plate.

[0095] The upper surface of the second fixing part 52 is attached to the upper side wall of the housing 1 to improve the compactness of the overall structure. At the same time, it can prevent the sound of the first speaker assembly 9 from spreading and improve the sound output effect.

[0096] like Figure 11 As shown, in some embodiments of this application, the front cover 2 includes a front cover portion 21 and a side cover portion 22 formed by bending backward along the circumferential edge of the front cover portion 21. The front cover portion 21 covers the front side of the housing 1, and the side cover portion 22 extends into the cavity from the front end of the housing 1. The side cover portion 22 is in contact with the inner side wall of the housing 1, and the side cover portion 22 is connected to the housing 1 by a snap-fit ​​mechanism and a third fastener.

[0097] The side cover 22 includes an upper side cover, a lower side cover, a left side cover, and a right side cover. The upper, left, and right side covers are all connected to the inner wall of the rear housing via a snap-fit ​​mechanism. The lower side cover is connected to the inner wall of the rear housing via both a snap-fit ​​mechanism and a third fastener. This arrangement places the third fastener on the lower side of the speaker 200, leaving the upper, left, and right sides without fasteners. This improves the aesthetic appearance of the soundbar 200 while ensuring the structural stability of the front grille 2 and the housing 1.

[0098] The structure of the related technology's soundbar 200, which fixes the front grille 2 and the housing 1 with fasteners, requires 22 to 32 screws. However, this application eliminates screws on the top, left, and right sides and adopts a snap-fit ​​structure, which greatly reduces the number of screws. In some embodiments of this application, the soundbar 200 uses only 8 screws to fix the front grille 2 and the housing 1.

[0099] In some embodiments of this application, a stepped surface 23 is formed between the side cover 22 and the front cover 21, and the front end of the housing 1 abuts against the stepped surface 23 so that the outer surface of the front cover 21 and the outer surface of the housing 1 can be smoothly joined together to form the appearance surface of the soundbar 200, thereby maintaining the integrity and aesthetics of the soundbar's appearance and improving the overall appearance quality of the soundbar.

[0100] In some embodiments of this application, the latching mechanism includes four types, such as... Figure 4 , 9 As shown in Figures 1 and 12, one type of snap-fit ​​mechanism includes a first snap-fit ​​221 on the side cover 22 and a first snap-fit ​​hole 41 on the housing 1. The first snap-fit ​​221 protrudes upward on the outer surface of the side cover 22 and then bends and extends towards the rear side of the housing 1, ultimately forming an L-shaped shape. The first snap-fit ​​hole 41 penetrates the upper sidewall of the housing 1 along the thickness direction, and the first snap-fit ​​221 snaps into the first snap-fit ​​hole 41. This allows the side cover 22 to be stably fixed to the housing 1, thereby maintaining the stability of the structural connection between the entire front cover 2 and the housing 1, and facilitating the installation and fixing of the front cover 21.

[0101] like Figure 3 As shown, in some embodiments of this application, the upper surface of the housing 1 is provided with a mounting groove 12, the projection of the first speaker assembly 9 on the upper side wall of the housing 1 is located in the mounting groove 12, the second mounting port 11 and the first snap-fit ​​hole 41 are both provided in the mounting groove 12, the net cover 10 is embedded in the mounting groove 12 to cover the second mounting port 11 and the first snap-fit ​​hole 41, and the upper surface of the net cover 10 is flush with the upper surface of the housing 1.

[0102] For example, the mounting groove 12 is rectangular in shape, and the second mounting opening 11 and the first snap-fit ​​hole 41 are both located at the bottom of the mounting groove 12. The mesh cover 10 can cover the second mounting opening 11 and the first snap-fit ​​hole 41 on the housing 1, preventing the first buckle 221 and the first snap-fit ​​hole 41 from being exposed on the outer surface of the soundbar 200, thus improving aesthetics. On the other hand, the mesh cover 10 is embedded in the mounting groove 12, with the upper surface of the mesh cover 10 flush with the upper surface of the housing 1. The circumferential edge of the mesh cover 10 abuts against the side wall of the mounting groove 12. The upper surface of the mesh cover 10 and the upper surface of the housing 1 can be smoothly joined together to form the upper side wall of the soundbar 200, thereby maintaining the integrity and aesthetics of the soundbar's appearance and improving the overall appearance quality of the soundbar.

[0103] In some embodiments of this application, each first mounting cavity 101 is provided with two first buckles 221 and two first snap holes 41 for cooperation, and the two first buckles 221 are spaced apart along the length direction of the front mesh cover 2.

[0104] In some embodiments of this application, the rear sidewall of the first snap-fit ​​hole 41 extends forward to form a snap-fit ​​arm 411, and the upper surface of the snap-fit ​​arm 411 is lower than the upper surface of the housing 1, so that when the first snap-fit ​​221 is snapped into place with the snap-fit ​​arm 411, the end face of the first snap-fit ​​221 away from the side cover 22 is lower than the bottom of the mounting groove 12 or flush with the bottom of the mounting groove 12.

[0105] After the first buckle 221 passes through the first snap-fit ​​hole 41, it abuts against the upper surface of the snap-fit ​​arm 411, thereby realizing the snap-fit ​​between the first buckle 221 and the snap-fit ​​arm 411, that is, the snap-fit ​​between the first buckle 221 and the first snap-fit ​​hole 41. The purpose of setting the snap-fit ​​arm 411 is that when the first buckle 221 passes through the first snap-fit ​​hole 41 to realize the snap-fit, the first buckle 221 will not be higher than the bottom of the mounting groove 12. In this way, when the net cover 10 is embedded in the mounting groove 12, the lower side of the net cover 10 can fit against the bottom of the mounting groove 12, and there will be no mutual interference between it and the first buckle 221, which improves the compactness of the installation structure.

[0106] For example, to prevent the first latch 221 and the first latching hole 41 from being exposed on the outer surface of the soundbar 200, the first latch 221 and the first latching hole 41 are positioned below the mesh cover 10. After the mesh cover 10 is installed, it can cover the first latch 221 and the first latching hole 41. It is understood that the first latch 221 and the first latching hole 41 are correspondingly set with the first mounting cavity 101. When the length of the soundbar 200 is relatively long, and the two first mounting cavities 101 are located at the left and right ends of the soundbar 200, and no screws are provided in the middle of the upper side of the housing 1, a second latching mechanism is required.

[0107] Specifically, such as Figures 7 to 13 As shown, in some embodiments of this application, the snap-fit ​​mechanism includes a second snap-fit ​​43 and a first snap-fit ​​groove 42 that cooperates with the second snap-fit ​​43. One of the second snap-fit ​​43 and the first snap-fit ​​groove 42 is disposed on the side cover 22 and the other is disposed on the housing 1. There are multiple second snap-fit ​​43s, and the multiple second snap-fit ​​43s are arranged at intervals along the circumference of the side cover 22 or the housing 1.

[0108] The first snap-fit ​​groove 42 is a rectangular groove, and the second snap-fit ​​43 is a rectangular protrusion. The second snap-fit ​​43 is embedded in the snap-fit ​​groove, and the height of the second snap-fit ​​43 is equal to the depth of the first snap-fit ​​groove 42. The appearance and size of the second snap-fit ​​43 and the first snap-fit ​​groove 42 are matched. When the second snap-fit ​​43 is embedded in the first snap-fit ​​groove 42, the end of the second snap-fit ​​43 abuts against the bottom of the groove, and the circumferential sidewall of the second snap-fit ​​43 abuts against the sidewall of the first snap-fit ​​groove 42, thus achieving the snap-fit ​​effect between them and ensuring that the side cover 22 and the sidewall of the housing 1 are fitted together. It is understood that the appearance of the snap-fit ​​groove and the second snap-fit ​​43 can also be other shapes.

[0109] For example, in some embodiments of this application, a portion of the first snap-fit ​​groove 42 is provided on the side cover portion 22, and a plurality of first snap-fit ​​grooves 42 are provided on the upper side cover portion along its own length direction. The plurality of first snap-fit ​​grooves 42 are mainly concentrated between the first mounting cavities 101 at both ends. A third snap-fit ​​groove 225 is provided on the left side cover portion and the right side cover portion respectively. A fourth buckle 45 is provided on the inner surface of the left side wall and the inner surface of the right side wall of the housing 1 respectively. A plurality of first snap-fit ​​grooves 42 are provided on the lower side cover portion along its own length direction, and a second buckle 43 is provided at the corresponding position on the inner surface of the lower side wall of the housing 1.

[0110] The upper side wall of the housing 1 is also provided with a third buckle 44, which is L-shaped. The corresponding position of the side cover 22 is located in the second snap-fit ​​groove 223, and the third buckle 44 is snapped into the second snap-fit ​​groove 223.

[0111] The front mesh cover 2 and the housing 1 are fixed by the cooperation of the first buckle 221 with the first snap hole 41, the second buckle 43 with the first snap groove 42, the third snap groove 225 with the fourth buckle 45, and the second snap groove 223 with the third buckle 44.

[0112] In some embodiments of this application, a fifth fixing hole 224 is provided on the lower side cover 22, and a sixth fixing hole 13 is provided at the corresponding position on the lower side wall of the housing 1. A third fastener passes through the sixth fixing hole 13 and the fifth fixing hole 224 sequentially from the bottom of the housing 1 to fix the lower side cover 22 to the lower side wall of the housing 1.

[0113] For example, in some embodiments of this application, eight fifth fixing holes 224 are provided on the lower side cover portion 22, and the fifth fixing holes 224 and the first snap-fit ​​groove 42 are staggered in the length direction of the lower side cover portion 22. The sixth fixing hole 13 is a smooth hole, the fifth fixing hole 224 is a threaded hole, the third fastener is provided with external threads, and the third fastener passes through the sixth fixing hole 13 and is screwed into the fifth fixing hole 224.

[0114] In the structure of the soundbar 200 in the above embodiments, the front grille 2 and the housing 1 are fixed by a variety of snap-fit ​​mechanisms and threaded connections, and multiple mechanical limits are achieved between the two.

[0115] like Figure 3 and Figure 6 As shown in some embodiments of this application, the rear sidewall of the housing 1 corresponding to the first mounting cavity 101 is provided with multiple spaced reinforcing ribs 14. Since the rear sidewall of the housing 1 does not serve as a support for fixing the speaker, the irregularity of the first mounting cavity 101 can be increased by providing reinforcing ribs 14 on the rear sidewall of the housing 1, thereby reducing the generation of standing waves and optimizing the sound output effect. Specifically, reinforcing ribs 14 with a uniform draft direction can be designed on the rear sidewall of the housing 1. The draft angle of the reinforcing ribs 14 can be set according to actual needs and is not specifically limited here.

[0116] In some embodiments of this application, the front end of the first fixing member or the front end of the second fixing member abuts against a structure on the front grille 2, thereby limiting the front grille 2. In some embodiments, the soundbar 200 also includes a touch panel, which is disposed on the top of the housing 1. The touch panel can sense human touch and generate corresponding control signals, thereby controlling the speaker to operate and achieve different functions.

[0117] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
