Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a duct and a soundbar speaker. Background Technology

[0002] Sound Blaster speakers are long, narrow audio devices that are typically placed below a television or mounted on a wall, primarily used to enhance the sound quality of televisions or other video equipment.

[0003] In related technologies, in order to be compatible with wall mounting, the Sound Blaster speaker is usually mounted on the wall by setting wall mounting holes on the rear panel of the speaker housing, and hooks installed on the wall are inserted into the wall mounting holes to hang the Sound Blaster speaker on the wall.

[0004] During the actual research and development process, the inventors discovered that once a wall-mounting hole was installed, the Sound Blaster speaker cavity would not be airtight, resulting in sound distortion and volume reduction, affecting the user's listening experience. Previously, in order to solve the airtightness problem of the Sound Blaster speaker, the inventors added an extra cover shell, which was fixedly installed on the rear panel to seal the end of the wall-mounting hole that connected to the Sound Blaster speaker cavity. However, the drawback of assembling an extra cover shell is that it increases the number of components and assembly steps of the Sound Blaster speaker, which not only increases the manufacturing cost of the Sound Blaster speaker, but also prolongs the assembly time due to the additional assembly steps, seriously limiting the assembly efficiency of the Sound Blaster speaker.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a duct that effectively solves the technical defects of the existing technology, which is that the soundbar speaker requires an additional cover shell to enclose the cavity and wall mounting holes, resulting in high manufacturing costs and low assembly efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a duct, including a duct shell, an extension cover on the outer surface of the duct shell, the extension cover having a blind hole, the extension cover being used to close the wall mounting hole of the soundbar speaker and to make the blind hole and the wall mounting hole conductively connected.

[0008] The beneficial effect of the duct provided in this application is that, compared with the prior art, after the duct is installed in the soundbar speaker, the wall mounting hole can be located in the area enclosed by the extension cover, and the wall mounting hole is connected to the blind hole by covering, thus isolating the connection between the wall mounting hole and the sound cavity.

[0009] Firstly, by integrally molding the extension cover into the air duct, the extension cover can close the connection between the wall mounting hole and the sound cavity after the air duct is assembled. Compared with traditional technology, this simplifies the assembly process of the Sound Blaster speaker, thereby shortening the assembly time of the Sound Blaster speaker and further improving its assembly production efficiency.

[0010] Secondly, since there is no need for an additional cover shell, no need for an additional injection mold to form the cover shell structure, and no need for screws to lock the cover shell to the Sound Blaster speaker, the overall manufacturing cost of the Sound Blaster speaker can be reduced by reducing the number of parts and injection molds.

[0011] As a preferred option, one end of the duct housing is provided with an air inlet and the other end with an air outlet, and the air inlet and air outlet are connected by an airflow channel.

[0012] As a preferred embodiment, the duct housing includes an upper housing and a lower housing, which are joined together by hot-melt welding.

[0013] The extension cover includes an upper extension shell integrally formed on the upper shell and a lower extension shell integrally formed on the lower shell; the upper extension shell and the lower extension shell are joined together by hot melt welding;

[0014] The blind hole is enclosed by the upper shell, lower shell, upper extended shell and lower extended shell, and the blind hole is not connected to the airflow channel.

[0015] As a preferred option, the duct housing has an assembly groove on the air outlet side, and an assembly pad is provided in the assembly groove.

[0016] As a preferred option, a sealing ring is provided on the rear surface of the extension cover.

[0017] This application also provides a Sound Blaster speaker, including a speaker housing with a wall mounting hole, and a duct installed on the speaker housing. When the duct is installed on the speaker housing, the wall mounting hole is located in the area enclosed by the extension cover and is connected to the blind hole of the cover.

[0018] The beneficial effect of the Sound Blaster speaker provided in this application is that, compared with the prior art, by installing the air duct after the speaker shell is installed, the wall mounting hole can be located within the area enclosed by the extension cover, and the connection between the wall mounting hole and the blind hole is isolated by covering the blind hole. Compared with the traditional technology, this simplifies the assembly process of the Sound Blaster speaker, thereby shortening the assembly time and further improving its assembly production efficiency.

[0019] As a preferred embodiment, the speaker housing includes a rear panel, an upper panel integrally formed above the rear panel, and a lower panel integrally formed below the rear panel. Both the upper and lower panels extend horizontally forward and are arranged parallel to each other.

[0024] On the side of the left and right panels facing the sound cavity, there are mounting ribs that protrude inward along the shape of the avoidance window;

[0025] The duct shell has an assembly groove on the air outlet side, and an assembly pad is placed in the assembly groove. After the left and right ducts are installed, the assembly rib can be inserted into the assembly groove and the gap between the assembly rib and the assembly groove is sealed by the assembly pad.

[0026] As a preferred embodiment, the upper panel has several L-shaped fasteners at the bottom front, with the L-shaped fasteners spaced from left to right; the lower panel has several L-shaped fasteners at the top front, with the L-shaped fasteners spaced from left to right.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Please refer to the following: Figures 1 to 9 The air duct provided in the embodiments of this application will now be described; since the air duct provided in this embodiment is mainly used for installation in the soundbar speaker, a soundbar speaker will be used as an example for description.

[0047] The Sound Blaster speaker includes a speaker housing 10, which has a sound cavity. The rear panel 11 of the speaker housing 10 has a wall mounting hole 111. Users can hang the Sound Blaster speaker on a wall or other support by attaching hooks or screws to the wall mounting hole 111. Before the duct is installed, the wall mounting hole 111 is connected to the sound cavity, allowing the sound cavity to communicate with the outside world. An extension cover is integrally formed on the rear side of the outer surface of the duct. The extension cover has a rearward-facing blind hole 206. The cross-sectional dimension of the extension cover is larger than that of the wall mounting hole 111. When the duct is installed in the sound cavity, the 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 hole 206.

[0048] Specifically, compared with existing technologies, installing the duct into the sound cavity allows the wall mounting hole 111 to be located within the area enclosed by the extension cover, and the blind hole 206 is used to connect the wall mounting hole 111 to the sound cavity, thus isolating the wall mounting hole 111 from the sound cavity. Firstly, by integrally molding the extension cover onto the duct, the extension cover can seal the connection between the wall mounting hole 111 and the sound cavity after the duct is assembled. Compared with traditional technologies, this simplifies the assembly process of the Sound Blaster speaker, thereby shortening the assembly time and further improving its assembly production efficiency. Secondly, since there is no need for an additional cover shell, no need for an additional injection mold to form the cover shell structure, and no need for screws to lock the cover shell to the Sound Blaster speaker, the overall manufacturing cost of the Sound Blaster speaker can be reduced by reducing the number of parts and injection molds.

[0049] In some embodiments, the speaker housing 10 further includes an upper side plate 12 integrally formed above the rear side plate 11 and a lower side plate 13 integrally formed below the rear side plate 11. The upper side plate 12 and the lower side plate 13 both extend horizontally forward and are arranged parallel to each other. A left side plate 14 is provided on the left side of the upper side plate 12, the lower side plate 13 and the rear side plate 11, and a right side plate 15 is provided on the right side of the upper side plate 12, the lower side plate 13 and the rear side plate 11. The upper side plate 12, the lower side plate 13, the left side plate 14, the right side plate 15 and the rear side plate 11 enclose a sound cavity with an opening facing forward, and the air duct is installed into the sound cavity from front to back.

[0050] Preferably, the acoustic cavity is provided with a left partition 16 and a right partition 17, both of which are integrally formed with the upper plate 12, the lower plate 13 and the rear plate 11; the left partition 16 and the left plate 14 are spaced apart to separate the left acoustic cavity 101, the right partition 17 and the right plate 15 are spaced apart to separate the right acoustic cavity 102, and the left partition 16 and the right partition 17 are spaced apart to separate the mounting cavity 103.

[0051] Specifically, by setting up a left acoustic cavity 101 and a right acoustic cavity 102 that are not interconnected, the sound of the left and right channels can be prevented from interfering with and mixing with each other within the wall; this can ensure the purity of the sound signals of the left and right channels, allowing the sound characteristics and details of the left and right channels to be fully preserved and output independently, thereby improving the separation and clarity of the sound, making the stereo effect more obvious, and allowing users to better perceive the direction and layering of the sound.

[0052] Furthermore, by using mounting cavities 103, which are not electrically connected to the left and right acoustic cavities 101 and 102, the direct impact of speaker assembly vibration on the circuit board located within the mounting cavities 103 can be reduced. This avoids problems such as loose components, solder joint detachment, or damaged wiring on the circuit board due to vibration, improving circuit stability and reliability, and extending the speaker's lifespan. Simultaneously, the circuit board generates an electromagnetic field during operation; the non-conductive nature of the acoustic cavities effectively isolates the electromagnetic interference generated by the circuit board from affecting audio signal transmission. This ensures pure audio signal transmission within the acoustic cavities, reducing noise and interference caused by electromagnetic interference, and ensuring the purity and fidelity of the output sound.

[0053] Understandably, after the front cover 18 is installed in the sound cavity opening, the left and right partitions abut against the rear side of the front cover, thus ensuring that the left sound cavity, right sound cavity and mounting cavity are in a state of non-communication.

[0054] Preferably, the left acoustic cavity 101 and the right acoustic cavity 102 are the same size, and the mounting cavity 103 is smaller than the dimensions of the left acoustic cavity 101 and the right acoustic cavity 102. Making the dimensions of the left acoustic cavity 101 and the right acoustic cavity 102 larger than the dimensions of the mounting cavity 103 provides more space for sound wave reflection and diffusion. Combined with the isolation function of the mounting cavity 103, this allows the sound waves of the left and right channels to fully form independent sound fields within their respective acoustic cavities, resulting in a more uniform and wider sound field distribution, improved stereo effect, and enhanced spatial and immersive sound.

[0055] Specifically, the upper panel 12 has several L-shaped fasteners 121 at the bottom front, spaced from left to right; the lower panel 13 has several L-shaped fasteners 121 at the top front, spaced from left to right; the speaker housing 10 also includes a front cover 18 covering the sound cavity opening, with mounting ribs 181 on the upper and lower rear sides of the front cover 18; after the front cover 18 is installed in the sound cavity opening, the mounting ribs 181 can be inserted into the L-shaped fasteners 121. This structure allows the L-shaped fasteners 121 to assist in the assembly of the front cover 18, thereby reducing the assembly difficulty of the front cover 18 and further improving the assembly efficiency of the Sound Blaster speaker; moreover, since the L-shaped fasteners 121 can restrict the specific position of the front cover 18, the size of the sound cavity can be accurately controlled to meet the design requirements after the front cover 18 is installed, improving the production yield of the Sound Blaster speaker.

[0056] More specifically, a left tweeter 110, a left woofer 120, a right tweeter 130, and a right woofer 140 are installed on the rear side of the front cover 18; after the front cover 18 is installed in 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.

[0057] It should be noted that the rear side of the front cover 18 has corresponding screw locking positions. The left tweeter 110, left woofer 120, right tweeter 130 and right woofer 140 are all connected to the screw locking positions by screws to complete the fixation. In addition, the left tweeter 110, left woofer 120, right tweeter 130 and right woofer 140 can also be fixed to the rear side of the front cover 18 by adhesive or welding.

[0058] Furthermore, mounting portions 182 extend rearward from both sides of the front cover 18, and mounting notches 141 are provided on the left side of the left panel 14 and the right side of the right panel 15; after the front cover 18 is installed in the sound cavity opening, the mounting portions 182 can be inserted into the mounting notches 141. The front cover 18 and the mounting portions 182 are covered with decorative parts 183.

[0059] Preferably, a screw hole is provided between the front cover and the upper side panel or between the front cover and the lower side panel, and a through hole is provided on the other side. The screw is passed through the through hole and screwed into the screw hole, which can fix the front cover at the opening of the sound cavity and make the front cover float on the front side of the speaker housing, improving the user's visual effect.

[0060] In other embodiments, a plurality of U-shaped ribs 104 are also included, which are disposed on the sides of the upper side plate 12, lower side plate 13, and rear side plate 11 facing the sound cavity; when the duct is installed in the sound cavity, the outer surface of the duct can abut against the plurality of U-shaped ribs 104. Firstly, by providing the U-shaped ribs 104, the thickness of the upper side plate 12, lower side plate 13, and rear side plate 11 can be made thinner, 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 prone to deformation; thirdly, they can provide support for the installation of the duct, preventing the duct from vibrating during the operation of the soundbar speaker, thereby improving the reliability of the duct.

[0061] Specifically, after the duct is installed in the sound cavity, the rear side of the extension cover and the front side of the rear panel 11 are fitted with a clearance fit; it also includes a sealing ring 27, the thickness of which is greater than the gap between the extension cover and the rear panel 11. With this structure, by providing sealing rings 27 on the rear side of the extension cover and the front side of the rear panel 11, the reliability and airtightness of the extension cover sealing the sound cavity and the wall mounting hole 111 can be improved, preventing sound leakage from the sound cavity through the gap between the extension cover and the rear panel 11.

[0062] More specifically, the duct includes a left duct 201 installed in the left acoustic cavity 101 and a right duct 202 installed in the right acoustic cavity 102. Both the left duct 201 and the right duct 202 include an airflow channel 203, an air inlet 204 connecting one end of the airflow channel 203, and an air outlet 205 connecting the other end of the airflow channel 203. The left panel 14 and the right panel 15 are provided with clearance windows 142 that penetrate through their left and right sides. The air outlet 205 of the left duct 201 is exposed in the clearance window 142 of the left panel 14, and the air outlet 205 of the right duct 202 is exposed in the clearance window 142 of the right panel 15.

[0063] It is understandable that the air inlet is located at one end of the length of the left and right air ducts, and the air outlet is located at the other end of the length of the left and right air ducts. The air inlet and the air outlet are connected by an airflow channel. The air inlet connects to the sound cavity, and the air outlet connects to the outside. This is a conventional design for air ducts, and will not be elaborated on here.

[0064] Preferably, on the side of the left plate 14 and the right plate 15 facing the sound cavity, there is an inwardly protruding mounting rib 143 along the shape of the avoidance window 142; the left air duct 201 and the right air duct 202 are provided with mounting grooves 25 on the side of the air outlet 205, and mounting pads 26 are provided in the mounting grooves 25; after the left air duct 201 and the right air duct 202 are installed, the mounting rib 143 can be inserted into the mounting groove 25 and the gap between the mounting rib 143 and the mounting groove 25 is sealed by the mounting pads 26.

[0065] It is understood that the left duct 201 and the right duct 202 can be fastened to the speaker housing 10 by screws; in addition, they can also be fixed by snap-fit, glue or welding.

[0066] In other embodiments, the duct housings of the left duct 201 and the right duct 202 both include an upper housing 21 and a lower housing 22, and the extension cover includes an upper extension housing 23 and a lower extension housing 24. The upper extension housing 23 and the upper housing 21 are integrally formed by injection molding, and the lower extension housing 24 and the lower housing 22 are integrally formed by injection molding. The upper housing 21 and the lower housing 22, as well as the upper extension housing 23 and the lower extension housing 24, are thermally fused together by ultrasonic welding to form an integrally structured duct and extension cover.

[0067] It is understandable that the left and right air ducts are connected to the extension cover by sealing the blind hole of the extension cover on the surface of the air duct housing and the airflow channel. This ensures that the blind hole is only connected to the wall mounting hole, so that after the air duct is installed in the speaker housing, the extension cover can be used to seal the connection between the wall mounting hole and the sound cavity.

[0068] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
