Description

Technical Field

[0001] The present invention relates to the technical field of soundbar speakers, and in particular to an assembly structure of a soundbar speaker and an air duct. Background Art

[0002] A soundbar is a long, thin audio device that is usually placed under a TV or hung on a wall. It is mainly used to improve the sound quality of a TV or other video equipment.

[0003] In the related art, in order to be compatible with hanging on the wall, a wall-hanging hole is usually provided on the rear panel of the soundbar housing, and a hook installed on the wall is buckled into the wall-hanging hole to hang the soundbar on the wall.

[0004] During the actual research and development process, the inventor discovered that once a wall-mounting hole is provided, the cavity of the sound bar speaker will not be airtight, resulting in sound distortion and reduced volume, affecting the user's auditory experience; before this, in order to solve the airtightness problem of the sound bar speaker, the inventor added an additional covering shell and fixed the covering shell on the rear panel to seal one end of the wall-mounting hole connected to the cavity of the sound bar speaker; however, the defect of the method of additionally assembling the covering shell is that it will increase the parts and assembly processes of the sound bar speaker, which not only increases the manufacturing cost of the sound bar speaker, but also prolongs the assembly time of the sound bar speaker due to the added assembly process, seriously limiting the assembly efficiency of the sound bar speaker.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0006] In view of this, the present invention addresses the deficiencies in the prior art. Its main purpose is to provide an assembly structure for a soundbar speaker and an air duct, which effectively solves the technical defects in the prior art, namely, the need for an additional cover shell to enclose the cavity and a wall-mounting hole, resulting in high manufacturing costs and low assembly efficiency for the soundbar speaker.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Please also refer to Figures 1 to 9 The assembly structure of the soundbar speaker and the air duct provided in the embodiment of the present application is now described. The assembly structure of the soundbar speaker and the air duct includes: a speaker housing 10 and an air duct.

[0027] The speaker housing 10 has a sound cavity. The rear panel 11 of the speaker housing 10 is provided with a wall-mounting hole 111. The user can install hooks or screws on the wall or other supporting objects and insert the hooks or screws into the wall-mounting hole 111 to hang the sound bar speaker on the wall or other supporting objects for use. Before the air duct is installed in the speaker housing 10, the wall-mounting hole 111 is connected to the sound cavity, allowing the sound cavity to communicate with the outside world through the wall-mounting hole 111. An extension cover is integrally formed on the rear side of the outer surface of the air duct. The extension cover has a blind cover hole 206 with a rearward opening. The cross-sectional dimensions of the extension cover are larger than the cross-sectional dimensions of the wall-mounting hole 111. When the air duct is installed in the sound cavity, the air duct is located in front of the rear panel 11. The rear surface of the extension cover can abut against the front surface of the rear panel 11, so that the wall-mounting hole 111 is located within the area enclosed by the extension cover and is connected to the blind cover hole 206.

[0028] Specifically, compared with the prior art, after the air duct is installed in the sound cavity, the wall-mounted hole 111 can be set within the area enclosed by the extended cover, and the blind hole 206 is covered to be conductively connected to the wall-mounted hole 111, thereby isolating the conductive connection between the wall-mounted hole 111 and the sound cavity; on the one hand, by integrally molding the extended cover on the air duct, the extended cover can seal the conductive connection between the wall-mounted hole 111 and the sound cavity after the air duct is assembled; compared with traditional technology, the assembly process of the sound bar speaker can be simplified, thereby shortening the assembly time of the sound bar speaker, and further improving its assembly production efficiency; on the other hand, since there is no need to set up an additional covering shell, there is no need to set up an additional injection mold to form the covering shell structure, and there is no need to set up screws to lock the covering shell to the sound bar speaker; the overall manufacturing cost of the sound bar speaker can be reduced by reducing the number of parts and injection molds.

[0029] In some embodiments, the speaker housing 10 also includes an upper panel 12 integrally formed above the rear panel 11 and a lower panel 13 integrally formed below the rear panel 11, and the upper panel 12 and the lower panel 13 both extend horizontally forward and are arranged parallel to each other; a left side panel 14 is provided on the left side of the upper panel 12, the lower panel 13 and the rear panel 11, and a right side panel 15 is provided on the right side of the upper panel 12, the lower panel 13 and the rear panel 11; the upper panel 12, the lower panel 13, the left side panel 14, the right side panel 15 and the rear panel 11 enclose a sound cavity with an opening facing forward, and the air duct is installed in the sound cavity from front to back.

[0030] Preferably, a left side partition 16 and a right side partition 17 are provided in the sound cavity, and the left side partition 16 and the right side partition 17 are integrally formed with the upper plate 12, the lower plate 13 and the rear plate 11; the left side partition 16 and the left side plate 14 are spaced apart and separate the left sound cavity 101, the right side partition 17 and the right side plate 15 are spaced apart and separate the right sound cavity 102, and the left side partition 16 and the right side partition 17 are spaced apart and separate the installation cavity 103.

[0031] Specifically, by setting up a left sound cavity 101 and a right sound cavity 102 that are not connected to each other, the sounds of the left and right channels can be prevented from interfering with and mixing with each other in the wall; the purity of the sound signals of the left and right channels can be guaranteed, so that the sound characteristics and details of the left and right channels can be fully preserved and output independently, thereby improving the separation and clarity of the sound, making the stereo effect more obvious, and the user can better feel the direction and layering of the sound.

[0032] Furthermore, by providing mounting cavity 103, which is not electrically connected to either the left or right sound cavity 101, 102, the direct impact of speaker assembly vibration on the circuit board within mounting cavity 103 can be reduced, preventing problems such as loosening of components on the circuit board, loss of solder joints, or damage to connecting lines caused by vibration. This improves the stability and reliability of the circuit and extends the life of the speaker. Furthermore, the circuit board generates an electromagnetic field during operation, and the non-conductive sound cavity effectively isolates the electromagnetic interference generated by the circuit board from affecting sound signal transmission. This ensures the pure transmission of audio signals within the sound cavity, reduces noise and hum caused by electromagnetic interference, and ensures the purity and fidelity of the output sound.

[0033] It can be understood that when the front cover 18 is installed on the sound cavity opening, the left and right partitions are both against the rear side of the front cover, thereby ensuring that the left sound cavity, the right sound cavity and the installation cavity are in a non-conductive state.

[0034] Preferably, the left and right sound cavities 101 and 102 are of the same size, and the mounting cavity 103 is smaller than the left and right sound cavities 101 and 102. The left and right sound cavities 101 and 102 being larger than the mounting cavity 103 provide ample space for sound waves to reflect and diffuse. Combined with the isolation provided by the mounting cavity 103, the sound waves from the left and right channels can fully form independent sound fields within their respective sound cavities, resulting in a more even and wide sound field distribution, an enhanced stereo effect, and a heightened sense of spatiality and presence.

[0035] Specifically, the upper plate 12 has a plurality of L-shaped buckles 121 at the bottom front, spaced from left to right. The lower plate 13 has a plurality of L-shaped buckles 121 at the top front, spaced from left to right. The speaker housing 10 also includes a front cover 18 that covers and is installed at the sound cavity opening. Mounting ribs 181 are provided on the upper and lower rear sides of the front cover 18. Once the front cover 18 is installed at the sound cavity opening, the mounting ribs 181 can be inserted into the L-shaped buckles 121. This structure facilitates the assembly of the front cover 18 through the L-shaped buckles 121, thereby reducing the assembly difficulty and further improving the assembly efficiency of the soundbar speaker. Furthermore, since the L-shaped buckles 121 can limit the specific position of the front cover 18, after the front cover 18 is installed, the size of the sound cavity can be accurately controlled to meet the design requirements, thereby improving the production yield of the soundbar speaker.

[0036] In more detail, the left tweeter 110, the left woofer 120, the right tweeter 130 and the right woofer 140 are installed on the rear side of the front cover 18; when the front cover 18 is installed at the sound cavity opening, the left tweeter 110 and the left woofer 120 are located in the left sound cavity 101, and the right tweeter 130 and the right woofer 140 are located in the right sound cavity 102.

[0037] It should be noted that corresponding screw locking positions are provided on the rear side of the front cover 18, and the left tweeter 110, the left woofer 120, the right tweeter 130 and the right woofer 140 are all connected to the screw locking positions by screws to complete the fixation; in addition, the left tweeter 110, the left woofer 120, the right tweeter 130 and the right woofer 140 can also be fixed to the rear side of the front cover 18 by gluing or welding.

[0038] Furthermore, mounting portions 182 extend rearward on both sides of the front cover 18. Mounting notches 141 are provided on the left side of the left panel 14 and the right side of the right panel 15. When the front cover 18 is installed in the sound cavity opening, the mounting portions 182 can be inserted into the mounting notches 141. The exterior of the front cover 18 and the mounting portions 182 are covered with decorative elements 183.

[0039] Preferably, between the front cover and the upper side plate or between the front cover and the lower side plate, one is provided with a screw hole and the other is provided with a through hole. The screw is passed through the through hole and screwed into the screw hole, so that the front cover can be fixedly installed at the opening of the sound cavity, and the front cover can be suspended on the front side of the speaker shell, thereby improving the user's visual effect.

[0040] In other embodiments, a plurality of U-shaped ribs 104 are further included. These ribs 104 are located on the sides of the upper panel 12, the lower panel 13, and the rear panel 11 that face the sound cavity. When the air duct is installed in the sound cavity, the outer surface of the air duct can rest against the plurality of U-shaped ribs 104. Firstly, the provision of the U-shaped ribs 104 allows the thickness of the upper panel 12, the lower panel 13, and the rear panel 11 to be made thinner, thereby reducing the overall weight of the speaker housing 10 and saving material waste. Secondly, the U-shaped ribs 104 can enhance the supporting strength of the entire speaker housing 10, making it less susceptible to deformation. Thirdly, they can provide support for the installation of the air duct, preventing the air duct from vibrating during operation of the soundbar speaker, thereby improving the reliability of the air duct.

[0041] Specifically, after the air duct is installed in the sound chamber, the rear side of the extension cover and the front side of the rear panel 11 are spaced apart. A sealing ring 27 is also included, the thickness of which is greater than the gap between the extension cover and the rear panel 11. This structure, by providing the sealing ring 27 on the rear side of the extension cover and the front side of the rear panel 11, can improve the reliability and airtightness of the extension cover in sealing the sound chamber and the wall-mounting hole 111, preventing sound leakage from the sound chamber through the gap between the extension cover and the rear panel 11.

[0042] In more detail, the air duct includes a left air duct 201 installed in the left sound cavity 101 and a right air duct 202 installed in the right sound cavity 102. The left air duct 201 and the right air duct 202 both include an air flow channel 203, an air inlet 204 connected to one end of the air flow channel 203, and an air outlet 205 connected to the other end of the air flow channel 203; the left plate 14 and the right plate 15 are provided with avoidance windows 142 running through the left and right sides thereof, the air outlet 205 of the left air duct 201 is exposed in the avoidance window 142 of the left plate 14, and the air outlet 205 of the right air duct 202 is exposed in the avoidance window 142 of the right plate 15.

[0043] It can be understood that the air inlet is arranged at one end of the left air duct and the right air duct in the length direction, and the air outlet is arranged at the other end of the left air duct and the right air duct in the length direction. The air inlet and the air outlet are connected through an air flow channel; the air inlet is connected to the sound cavity, and the air outlet is connected to the outside world. This is the conventional design of the air duct and will not be elaborated here.

[0044] Preferably, an assembly rib 143 is provided on the side of the left plate 14 and the right plate 15 facing the sound cavity, protruding inward along the shape of the avoidance window 142; the left air duct 201 and the right air duct 202 are provided with an assembly groove 25 on one side of the air outlet 205, and an assembly rubber pad 26 is provided in the assembly groove 25; when the left air duct 201 and the right air duct 202 are installed, the assembly rib 143 can be inserted into the assembly groove 25 and the gap between the assembly rib 143 and the assembly groove 25 can be closed by the assembly rubber pad 26.

[0045] It is understandable that the left air duct 201 and the right air duct 202 can be fixed to the speaker housing 10 by screws; in addition, any other method of fastening, gluing or welding can also be used.

[0046] In other embodiments, the air duct shells of the left air duct 201 and the right air duct 202 both include an upper shell 21 and a lower shell 22, and the extension cover includes an upper extension shell 23 and a lower extension shell 24. The upper extension shell 23 and the upper shell 21 are integrally formed by an injection mold, and the lower extension shell 24 and the lower shell 22 are integrally formed by an injection mold; the upper shell 21 and the lower shell 22 and the upper extension shell 23 and the lower extension shell 24 are hot-melt together by ultrasonic welding to form an air duct and extension cover with an integrated structure.

[0047] It can be understood that the left side air duct and the right side air duct are respectively connected to the extension cover by closing the cover blind hole of the extension cover and the air flow channel through the surface of the air duct shell, so that the cover blind hole is only connected to the wall-mounted hole. After the air duct is installed in the speaker shell, the extension cover can be used to close the conductive connection between the wall-mounted hole and the sound cavity.

[0048] The above is merely a preferred embodiment of the present invention and specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
