Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of embedded sound equipment, and particularly relates to an embedded sound equipment and a use method. BACKGROUND

[0002] The embedded sound equipment is usually installed in a reserved cavity of a wall, a ceiling or custom furniture to realize visual integration with the building environment and improve the aesthetic level.

[0003] Due to the installation characteristics of the embedded sound equipment, the equipment body is closed or semi-closed in the cavity space of the wall or the ceiling. The ventilation condition of the cavity space is usually very poor, and the air circulation is limited. When the equipment works for a long time, especially at high power output, the heat generated by the core components such as the power amplifier module and the driving unit is difficult to dissipate effectively. The heat continuously accumulates in the cavity, which causes the internal temperature of the equipment to rise significantly. This not only accelerates the aging of electronic components, reduces the service life and stability, but also may cause the performance degradation of the voice coil due to overheating, and even cause the demagnetization of the magnetic system, which seriously damages the sound quality performance and the reliability of the equipment. Secondly, the design of the existing embedded sound equipment usually focuses on the acoustic performance and installation convenience, and lacks attention to the long-term sealing protection of the equipment in the non-working (shutdown) state. Dust, fibers and other particles in the environment can easily enter the box interior and the key parts such as the unit diaphragm and the magnetic gap through these gaps. Moisture can corrode metal components, causing oxidation and corrosion, which significantly reduces the sensitivity and service life of the loudspeaker unit. In addition, condensation is easily produced in the non-sealed cavity due to changes in temperature and humidity, which further aggravates the moisture damage. The above sealing defects also mean that the equipment lacks basic protection against insects and other small organisms.

[0004] The above-mentioned problems of poor heat dissipation and poor sealing are interwoven, which together cause the existing embedded sound equipment to have the following significant defects in actual application: low reliability, shortened service life, increased maintenance cost, difficult to guarantee the stability of sound quality, and limited application in harsh environments such as moisture and dust. Heat accumulation accelerates the aging of sealing materials, and dust and moisture introduced by sealing failure further deteriorate the heat dissipation environment and directly damage internal components. Therefore, there is an urgent need for a new technical solution that can effectively solve the heat dissipation bottleneck of the embedded sound equipment and significantly improve its sealing, moisture-proof and dust-proof capability in the non-working state. SUMMARY

[0005] The purpose of the embodiments of the present application is to provide an embedded sound equipment and a use method, which aims to solve the problem of poor heat dissipation and sealing effect of the existing embedded sound equipment.

[0006] This invention is implemented as follows: an embedded audio device includes an embedded housing and a telescopic housing slidably connected within the embedded housing. A speaker is mounted within the telescopic housing via a bracket. Multiple heat dissipation slits are evenly distributed on the sidewall of the telescopic housing. A telescopic component for moving the telescopic housing is installed within the embedded housing. A top mounting shell and a bottom mounting shell are fixed to the top and bottom of the telescopic housing, respectively. Multiple grilles are evenly rotatably connected between the top and bottom mounting shells. An opening and closing component is provided on the top mounting shell. When the telescopic housing is retracted inside the embedded housing, the opening and closing component causes the multiple grilles to rotate, sealing the end of the telescopic housing away from the embedded housing. When the telescopic housing extends out of the embedded housing, the opening and closing component causes the multiple grilles to reverse, opening the end of the telescopic housing away from the embedded housing.

[0007] A further technical solution is that the telescopic assembly includes a telescopic member fixedly embedded in the housing, and an installation block fixedly embedded in the telescopic housing. The installation block has an insertion hole at one end near the telescopic member, and a limit bolt is threadedly connected to the side wall of the installation block. The end of the limit bolt extends into the insertion hole and abuts against the telescopic end side wall of the telescopic member.

[0008] A further technical solution includes a guide groove horizontally arranged inside the top mounting shell, a rack plate slidably connected inside the guide groove, one end of multiple grilles extending into the top mounting shell and fixed with a gear and a torsion spring, the end of the torsion spring being fixed inside the top mounting shell, the gear meshing with the rack plate, a push groove provided at the bottom of the rack plate, and a transmission slide plate slidably connected inside the telescopic shell, the transmission slide plate cooperating with the push groove, and the mating surface between the transmission slide plate and the push groove being an inclined surface.

[0009] A further technical solution includes a first rotating frame rotatably connected inside a telescopic housing. The first rotating frame rotates along its vertical axis. A second rotating frame is rotatably connected inside the first rotating frame. The second rotating frame rotates along its horizontal axis. A first motor is fixed on one side wall of the first rotating frame. The rotating end of the first motor is connected to the second rotating frame. The speaker is mounted on the second rotating frame. A rotating assembly is installed inside the telescopic housing. The rotating assembly is used to drive the first rotating frame to rotate.

[0010] A further technical solution is provided with a transmission groove on the side wall of the rotating frame one, and a transmission ring is rotatably connected to the upper part of the rotating frame one. The transmission groove is located inside the transmission ring, and a horizontal sliding groove is provided inside the transmission ring. A friction block is slidably connected inside the sliding groove. One end of the friction block extends into the transmission ring, and the other end of the friction block is connected to a compression spring. The end of the compression spring is fixed inside the sliding groove. The transmission ring is connected to one of the grilles via a belt and a pulley.

[0011] In a further technical solution, the rotating assembly includes a second gear fixed at the lower part of the rotating frame and a second motor fixed inside the telescopic housing. A third gear is fixed at the rotating end of the second motor, and the third gear meshes with the second gear.

[0012] A method of using an embedded audio device, based on the aforementioned embedded audio device, includes the following steps:

[0013] Step 1: The telescopic component moves the telescopic housing, which in turn causes the speaker inside the telescopic housing to extend out and embed into the housing.

[0014] Step 2: When the telescopic housing extends out of the embedded housing, the opening and closing assembly drives multiple grilles to reverse, and the multiple grilles open the end of the telescopic housing away from the embedded housing;

[0015] Step 3: The bracket drives the speaker to adjust its angle, and the bracket drives the grille to rotate horizontally in sync. The horizontal projection of the speaker's amplification direction is parallel to the width direction of the grille.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] When not in use, the telescopic housing retracts into the embedded housing, and multiple grilles seal the end of the telescopic housing away from the embedded housing. The heat dissipation gaps on the side wall of the telescopic housing are blocked by the embedded housing. At this time, the inside of the telescopic housing is sealed, and external dust, moisture and small animals cannot enter the telescopic housing, thus protecting the electronic components inside the embedded speaker.

[0018] When using an embedded speaker, the telescopic housing extends out of the embedded housing. Multiple grilles open the end of the telescopic housing away from the embedded housing, and heat dissipation gaps extend out of the embedded housing. The telescopic housing drives the speaker and other electrical components to extend out of the embedded housing. Through the gaps between the multiple grilles and the heat dissipation gaps around the telescopic housing, the electrical components inside the embedded speaker can be effectively cooled, avoiding heat accumulation.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 andFigure 6 As shown, an embedded audio device according to an embodiment of the present invention includes an embedded housing 101, and further includes a telescopic housing 102 slidably connected within the embedded housing 101. A speaker is mounted within the telescopic housing 102 via a bracket. Multiple heat dissipation gaps 106 are evenly distributed on the sidewall of the telescopic housing 102. A telescopic component 3 for moving the telescopic housing 102 is installed within the embedded housing 101. A top mounting shell 103 and a bottom mounting shell 104 are respectively fixed to the top and bottom of the telescopic housing 102. Multiple grilles 105 are rotatably connected between the mounting shell 103 and the bottom mounting shell 104. An opening and closing assembly 2 is provided on the top mounting shell 103. When the telescopic shell 102 is retracted inside the embedded shell 101, the opening and closing assembly 2 drives the multiple grilles 105 to rotate, and the multiple grilles 105 seal the end of the telescopic shell 102 away from the embedded shell 101. When the telescopic shell 102 extends out of the embedded shell 101, the opening and closing assembly 2 drives the multiple grilles 105 to reverse, and the multiple grilles 105 open the end of the telescopic shell 102 away from the embedded shell 101.

[0033] In this embodiment of the invention, the embedded housing 101 is installed in a pre-reserved groove in a wall or cabinet using expansion bolts or other connecting components. When not in use, the telescopic assembly 3 causes the telescopic housing 102 to retract into the embedded housing 101 (e.g., ...). Figure 1 As shown), multiple grilles 105 seal the end of the telescopic housing 102 away from the embedded housing 101. The heat dissipation gaps 106 on the side wall of the telescopic housing 102 are blocked by the embedded housing 101. At this time, the inside of the telescopic housing 102 is sealed, and external dust, moisture and small animals cannot enter the telescopic housing 102, thereby protecting the electronic components inside the embedded speaker.

[0034] When using an embedded speaker, the telescopic component 3 causes the telescopic housing 102 to extend out of the embedded housing 101 (e.g., Figure 2 As shown), the opening and closing component 2 drives multiple grilles 105 to reverse, and the multiple grilles 105 open the end of the telescopic housing 102 away from the embedded housing 101. The heat dissipation gap 106 extends out of the embedded housing 101, and the telescopic housing 102 drives the speaker and other electrical components to extend out of the embedded housing 101. Through the gaps between the multiple grilles 105 and the heat dissipation gap 106 on the periphery of the telescopic housing 102, the electrical components in the embedded speaker can be effectively cooled, avoiding heat accumulation. By extending the telescopic housing 102 into and out of the embedded housing 101, the heat dissipation and sealing effects of the embedded speaker can be achieved.

[0035] like Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, in a preferred embodiment of the present invention, the telescopic component 3 includes a telescopic member 301 fixedly embedded in the housing 101 and a mounting block 302 fixedly embedded in the telescopic housing 102. The mounting block 302 is provided with an insertion hole 303 at one end near the telescopic member 301. A limit bolt is threadedly connected to the side wall of the mounting block 302, and the end of the limit bolt extends into the insertion hole 303 and abuts against the telescopic end side wall of the telescopic member 301.

[0036] In this embodiment of the invention, the telescopic component 301 can be an electric telescopic rod. When repairing the embedded audio system, the telescopic housing 102 extends out of the embedded housing 101 (e.g., Figure 2 As shown, by tightening the limiting bolt through the heat dissipation gap 106, the limiting bolt is not engaged with the side wall of the telescopic end of the telescopic component 301. The telescopic end of the telescopic component 301 is then pulled out from the insertion hole 303, allowing the telescopic housing 102 to be removed. This facilitates the maintenance of the electrical components inside the telescopic housing 102. After maintenance, the telescopic housing 102 is reinserted into the embedded housing 101, and the telescopic end of the telescopic component 301 is reinserted into the insertion hole 303. Then, the limiting bolt is tightened through the heat dissipation gap 106, so that the end of the limiting bolt abuts against the side wall of the telescopic end of the telescopic component 301, thus completing the installation of the telescopic housing 102. Due to the detachable design of the telescopic housing 102, it is not necessary to remove the entire embedded speaker from the reserved slot in the wall or cabinet when maintaining or replacing electrical components.

[0037] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the opening and closing assembly 2 includes a guide groove 201 horizontally arranged inside the top mounting shell 103. A rack plate 202 is slidably connected inside the guide groove 201. One end of a plurality of grilles 105 extends into the top mounting shell 103 and is fixed with a gear 203 and a torsion spring 204. The end of the torsion spring 204 is fixed inside the top mounting shell 103. The gear 203 meshes with the rack plate 202. A push groove 206 is provided at the bottom of the rack plate 202. A transmission slide plate 205 is slidably connected inside the telescopic shell 102. The transmission slide plate 205 cooperates with the push groove 206, and the cooperation surface between the transmission slide plate 205 and the push groove 206 is an inclined surface.

[0038] In this embodiment of the invention, when the telescopic housing 102 extends into the embedded housing 101, the telescopic housing 102 drives the transmission slide plate 205 to extend into the embedded housing 101 until the transmission slide plate 205 contacts the inner wall of the embedded housing 101 and the transmission slide plate 205 can no longer move. When the telescopic housing 102 continues to extend into the embedded housing 101, the transmission slide plate 205 moves relative to the telescopic housing 102. The transmission slide plate 205 pushes the rack plate 202 to move through the inclined surface. The rack plate 202 drives multiple gears 203 to rotate synchronously. The multiple gears 203 drive multiple grilles 105 to rotate synchronously, thereby causing the grilles 105 to overcome the elastic force of the torsion spring 204 and rotate until the telescopic housing 102 is completely inserted into the embedded housing 101. The multiple grilles 105 seal the end of the telescopic housing 102 away from the embedded housing 101.

[0039] When the telescopic housing 102 extends out of the embedded housing 101, the thrust on the transmission slide plate 205 disappears, and the torsion spring 204 drives the grille 105 to reverse and reset, thereby causing the grille 105 to open the end of the telescopic housing 102 away from the embedded housing 101.

[0040] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, the bracket includes a rotating frame 401 rotatably connected within a telescopic housing 102. The rotating frame 401 rotates along its vertical axis. A rotating frame 402 is rotatably connected within the rotating frame 401. The rotating frame 402 rotates along its horizontal axis. A motor 403 is fixedly mounted on the side wall of the rotating frame 401. The rotating end of the motor 403 is connected to the rotating frame 402. The speaker is mounted on the rotating frame 402. A rotating assembly 7 is installed within the telescopic housing 102. The rotating assembly 7 is used to drive the rotating frame 401 to rotate. The rotating assembly 7 includes a gear 701 fixed to the lower part of the rotating frame 401 and a motor 702 fixed within the telescopic housing 102. A gear 703 is fixed to the rotating end of the motor 702, and the gear 703 meshes with the gear 701.

[0041] In this embodiment of the invention, during use, the speaker angle can be adjusted according to changes in the listening position. Specifically, motor 1 403 drives rotating frame 2 402 to rotate up and down, rotating frame 2 402 drives the speaker to adjust its up and down angle, motor 2 702 drives gear 3 703 to rotate, gear 3 703 drives gear 2 701 to rotate, gear 2 701 drives rotating frame 1 401 to rotate horizontally, rotating frame 1 401 drives rotating frame 2 402 to rotate horizontally, rotating frame 2 402 drives the speaker to adjust its horizontal angle. Compared to existing embedded speakers, which cannot adjust the amplification angle after installation, this invention can adjust the speaker angle according to changes in the listening position, making it convenient for the use of embedded speakers.

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a preferred embodiment of the present invention, a transmission groove 501 is provided on the side wall of the rotating frame 401, and a transmission ring 502 is rotatably connected to the upper part of the rotating frame 401. The transmission groove 501 is located inside the transmission ring 502, and a horizontal sliding groove 503 is provided inside the transmission ring 502. A friction block 505 is slidably connected inside the sliding groove 503. One end of the friction block 505 extends into the transmission ring 502, and the other end of the friction block 505 is connected to a compression spring 504. The end of the compression spring 504 is fixed inside the sliding groove 503. The transmission ring 502 is connected to one of the grilles 105 via a belt and a pulley. Specifically, a synchronous pulley 601 is fixed on one of the grilles 105, and a synchronous pulley 602 is fixed on the side wall of the transmission ring 502. The synchronous pulley 601 and the synchronous pulley 602 are connected via a synchronous belt 603.

[0043] In this embodiment of the invention, when the telescopic housing 102 extends out of the embedded housing 101, the torsion spring 204 drives the grille 105 to rotate. One of the grilles 105 drives the synchronous pulley 601 to rotate. The synchronous pulley 601 drives the transmission ring 502 to rotate via the synchronous belt 603. The transmission ring 502 drives the friction block 505 to rotate until the friction block 505 coincides with the transmission groove 501 on the grille 105. At this time, the compression spring 504 pushes the friction block 505 into the transmission groove 501. The transmission ring 502 is connected to the rotating frame 401 by friction. At this time, one of the grilles 105 and the rotating frame 401 are connected by friction. 1. Transmission connection: When the rotating frame 401 drives the speaker to adjust the horizontal angle, the rotating frame 401 drives the transmission ring 502 to rotate through friction. The transmission ring 502 drives one of the grilles 105 to rotate through the synchronous pulley 602, the synchronous belt 603 and the synchronous pulley 601. One of the grilles 105 drives the other grilles 105 to rotate synchronously through the rack plate 202 and multiple gears 203. As a result, the horizontal projection of the speaker's sound amplification direction is parallel to the width direction of the grille 105, so that the grille 105 does not block the speaker's sound amplification path when the speaker's horizontal angle is adjusted.

[0044] When the telescopic housing 102 retracts into the embedded housing 101, the transmission slide plate 205 contacts the inner wall of the embedded housing 101. The transmission slide plate 205 then pushes the rack plate 202 to move. The rack plate 202 drives multiple gears 203 to rotate, which in turn drives multiple grilles 105 to rotate. One of the grilles 105 drives a timing pulley 601 to rotate. The timing pulley 601, via the timing belt 603, drives a timing pulley 602 to rotate. The timing pulley 602 drives a transmission ring 502 to rotate, which in turn drives a friction block 505 to rotate. 05 overcomes the elastic force of the compression spring 504 and retracts into the sliding groove 503, and the transmission ring 502 is not connected to the rotating frame 401; through the friction transmission between the transmission ring 502 and the rotating frame 401, and the setting of the torsion spring 204, when the telescopic housing 102 extends out of the embedded housing 101, the friction block 505 can automatically engage with the transmission groove 501, realizing the transmission connection between the transmission ring 502 and the rotating frame 401. Alternatively, when the telescopic housing 102 extends into the embedded housing 101, the transmission ring 502 is disconnected from the rotating frame 401, realizing the autonomous rotation of the grille 105.

[0045] The above embodiments of the present invention provide an embedded audio device. The embedded housing 101 is installed in a reserved groove in the wall or cabinet by means of expansion bolts or other connecting parts. When the embedded audio device is used, the telescopic member 301 extends, and the telescopic member 301 drives the telescopic housing 102 to extend out of the embedded housing 101 (e.g., Figure 2As shown), the thrust on the transmission slide plate 205 disappears, and the torsion spring 204 drives the grille 105 to reverse. One of the grilles 105 drives the synchronous pulley 601 to rotate. The synchronous pulley 601 drives the transmission ring 502 to rotate through the synchronous belt 603. The transmission ring 502 drives the friction block 505 to rotate until the friction block 505 coincides with the transmission groove 501 on the grille 105. At this time, the compression spring 504 pushes the friction block 505 into the transmission groove 501. The transmission ring 502 is connected to the rotating frame 401 by friction. At this time, one of the grilles 105 is connected to the rotating frame 401 by transmission. The rotating assembly 7 drives the rotating frame 401 to rotate. The rotating frame 401 drives the rotating frame 402 to rotate horizontally. The rotating frame 402 drives the speaker to adjust its horizontal angle. The rotating frame 401 drives the transmission ring 502 to rotate through friction. The transmission ring 502 drives one of the grilles 105 to rotate through the synchronous pulley 602, the synchronous belt 603 and the synchronous pulley 601. One of the grilles 105 drives the other grilles 105 to rotate synchronously through the rack plate 202 and multiple gears 203. This makes the horizontal projection of the speaker's sound amplification direction parallel to the width direction of the grille 105, so that the grille 105 does not block the speaker's sound amplification path when the speaker's horizontal angle is adjusted.

[0046] When not in use, the telescopic component 301 retracts, causing the telescopic housing 102 to retract into the embedded housing 101 (e.g., Figure 1As shown), the telescopic housing 102 drives the transmission slide plate 205 to extend into the embedded housing 101 until the transmission slide plate 205 contacts the inner wall of the embedded housing 101, at which point the transmission slide plate 205 can no longer move. When the telescopic housing 102 continues to extend into the embedded housing 101, the transmission slide plate 205 moves relative to the telescopic housing 102. The transmission slide plate 205 pushes the rack plate 202 to move through the inclined plane. The rack plate 202 drives multiple gears 203 to rotate synchronously. The multiple gears 203 drive multiple grilles 105 to rotate synchronously. One of the grilles 105 drives the synchronous pulley 601 to rotate. The synchronous pulley 601 drives the synchronous pulley 602 to rotate through the synchronous belt 603. The synchronous pulley 602 drives the transmission ring 502 to rotate. The transmission ring 502 drives the friction block 505 to rotate, thereby increasing the friction. Block 505 overcomes the elastic force of compression spring 504 and retracts into sliding groove 503. Transmission ring 502 is not connected to rotating frame 401. The grid 105 overcomes the elastic force of torsion spring 204 and rotates until telescopic housing 102 is fully inserted into embedded housing 101. Multiple grids 105 seal the end of telescopic housing 102 away from embedded housing 101. Through friction transmission between transmission ring 502 and rotating frame 401, and the setting of torsion spring 204, when telescopic housing 102 extends out of embedded housing 101, friction block 505 can automatically engage with transmission groove 501, realizing transmission connection between transmission ring 502 and rotating frame 401. Alternatively, when telescopic housing 102 extends into embedded housing 101, transmission ring 502 is disconnected from rotating frame 401, realizing autonomous rotation of grid 105.

[0047] A method of using an embedded audio device, based on the aforementioned embedded audio device, includes the following steps:

[0048] Step 1: The telescopic component 3 drives the telescopic housing 102 to move, and the telescopic housing 102 drives the speaker inside the telescopic housing 102 to extend out and embed into the housing 101.

[0049] Step 2: When the telescopic housing 102 extends out of the embedded housing 101, the opening and closing component 2 drives multiple grilles 105 to reverse, and the multiple grilles 105 open the end of the telescopic housing 102 away from the embedded housing 101.

[0050] Step 3: The bracket drives the speaker to adjust its angle. The bracket drives the grille 105 to rotate horizontally in sync. The horizontal projection of the speaker's amplification direction is parallel to the width direction of the grille 105.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
