Description

Technical Field

[0001] This utility model relates to a wall-mounted speaker. Background Technology

[0002] Wall-mounted speakers are speakers that are suspended and installed on a wall. On the one hand, they reduce the space occupied on the floor or desktop; on the other hand, they provide a foundation for omnidirectional sound sources. Currently, most wall-mounted speakers on the market are directly mounted to the wall using screws or mounting brackets. This installation structure is easy to manufacture and install, but after installation, the following problems easily arise: 1. The installation angle is fixed, making it impossible to flexibly adjust the speaker's orientation; 2. The installation is unreliable, especially after prolonged use. With speaker vibration, the mounting screws may loosen, potentially causing the speaker to fall and posing a safety hazard. Furthermore, the assembly of existing wall-mounted speaker shells mostly uses screws for fastening. In humid conditions (especially in lower floors in southern regions where humidity is higher when installed close to the wall), moisture in the air can easily enter the speaker and come into contact with the screws, causing the screws to rust. This makes it difficult to disassemble and repair the speaker in case of malfunction. Therefore, shims need to be used during installation, but this also leads to cumbersome installation work and increased costs. Therefore, this utility model provides a wall-mounted speaker and its installation structure that solves the above-mentioned technical problems. Utility Model Content

[0003] To solve the aforementioned technical problems, this utility model proposes a wall-mounted speaker, comprising a speaker body, a mounting bracket, and a protective component, wherein...

[0004] The speaker body includes a shell and a cover. The shell has a mounting cavity with mounting posts around its perimeter. Each mounting post has a sealing screw hole at its end. The cover seals the mounting opening of the mounting cavity. The outer side of the cover, corresponding to the end of the mounting post, has a screw groove. The center of the screw groove has a locking through hole aligned with the sealing screw hole. The bottom of the screw groove has an annular boss surrounding the locking through hole, with a triangular or trapezoidal cross-section. The shell and cover are fixed in place by locking screws passing through the locking through hole and screwed into the sealing screw hole. The head of the locking screw presses against the annular boss to form a seal, thus sealing the screw shaft even without a gasket, preventing it from rusting due to moisture.

[0005] The mounting bracket is C-shaped, with both ends rotatably mounted to the upper and lower ends of the speaker body, and a flat wall-mounted seat in the middle. The wall-mounted seat is fixed to the wall by fastening screws, thus allowing the wall-mounted speaker to swing and has a high degree of flexibility.

[0006] The safety component includes a safety hook and a safety connector. One safety hook is installed on the back of the speaker body, and the other safety hook is installed on the wall. The two ends of the safety connector are respectively connected to the two safety hooks. When the mounting bracket is detached from the wall, the safety connector can suspend the entire speaker body to prevent the speaker body from falling and damaging or injuring people.

[0007] Preferably, the safety connector is a steel rope, which is sturdy, reliable, and has a strong load-bearing capacity; or the safety connector is a long spring, which, through its elastic tension, can prevent the wall-mounted speaker from being damaged by rigid impact when it falls.

[0008] Preferably, the mounting bracket has a concealed mounting structure at both ends that inserts into the back of the speaker body. The back of the speaker body has two insertion slots at its upper and lower edges, and bracket screw holes are located at the edges near the back of the speaker body at both ends. These screw holes pass through the two insertion slots. Both ends of the mounting bracket are inserted into the two insertion slots, and each end is secured by a stud that passes through and is screwed into the bracket screw hole.

[0009] Preferably, to prevent the ends of the mounting bracket from being too thin and twisting, thickened rubber plates are provided at both the upper and lower ends of the mounting bracket. These thickened rubber plates are installed on the outer surfaces of the upper and lower ends of the mounting bracket and have limiting grooves for the ends of the mounting bracket to insert into. A silicone pad is provided between the inner surface of the end of the mounting bracket and the speaker body. The silicone pad has anti-slip textures on the side facing the speaker body to prevent the wall-mounted speaker from being mispositioned.

[0010] Preferably, the thickened rubber plate has a protruding post on the side opposite to the end of the mounting bracket, and the end of the protruding post has a countersunk hole aligned with the screw hole of the bracket. The fixing stud passes through the countersunk hole, the hole at the end of the mounting bracket, the hole of the silicone pad, and the screw hole of the bracket in sequence.

[0011] Preferably, the upper and lower ends of the speaker body have recesses near the back edge for protruding studs to be exposed. The insertion slot is trapezoidal. The hole of the silicone pad is smaller than the diameter of the fixing stud, thereby avoiding the problem of the fixing stud easily falling off before tightening or before the mounting bracket is installed.

[0012] Preferably, the upper and lower ends of the housing are provided with through-holes, and a plug is fixedly installed at the end of the mounting hole facing inward. The plug is provided with a screw hole coaxial with the mounting hole and forms the screw hole of the bracket, which can reduce the molding difficulty of the housing.

[0013] Preferably, the mounting opening of the housing covers the periphery of the faceplate, and a gap is provided between the inner wall of the mounting opening and the periphery of the faceplate. The wall-mounted speaker also includes an aluminum mesh, which covers the outer side of the faceplate, and the periphery of the aluminum mesh is inserted into the gap. The outer periphery of the mounting opening has pin holes, and pins are screwed in to lock the aluminum mesh, making the installation of the aluminum mesh very secure and not easy to fall off.

[0014] Preferably, a tweeter is installed inside the speaker body. The tweeter's diaphragm is made of silk dome and has a coaxial large dome and a small surround. Both the large dome and the small surround have their own phases. From the perspective of sound wave propagation, the large dome is closer to the user, and the two components cancel each other out and interfere with each other during propagation. Therefore, this invention provides a pressing ring on the outer ring of the diaphragm. The pressing ring presses down and covers half of the small surround, causing sound propagation to bypass the blocked part and propagate forward, thereby adjusting the phase of the small surround to be more consistent with that of the large dome. Furthermore, the tweeter's diaphragm uses copper foil to directly lead out wires, resulting in stronger adhesion and better stability.

[0015] Preferably, a woofer is installed inside the speaker enclosure. The woofer's diaphragm uses copper foil to directly lead out wires, resulting in stronger adhesion and better stability. The woofer's diaphragm is made of PP cone, which is waterproof and dustproof. In addition, the woofer's diaphragm has a structure that is thicker in the middle and gradually thins towards the periphery, allowing for uniform movement during vibration, more symmetrical vertical vibration, and better tone.

[0016] Preferably, the voice coils of both the tweeter and woofer employ a double-wire parallel winding structure, with the two ends of the double wires welded together at the ends. With the same cross-sectional area as a single wire, the double wire has a larger surface area, reducing the effective resistance to higher frequency currents. Therefore, with the same number of coils and the same width, the coil thickness and weight of the double-wire parallel winding structure are reduced, thereby decreasing the weight of the voice coil and the vibration system, increasing the voice coil sensitivity, and ultimately improving sound quality.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] 1. An annular boss is provided around the locking through hole. When the locking screw is locked in, the bottom end of the head of the locking screw presses against the annular boss and forms a seal. Thus, even without a washer, the screw shaft of the locking screw can be sealed to prevent it from contacting moisture and rusting.

[0019] 2. The wall-mounted speaker is mounted on a swing bracket, providing high flexibility.

[0020] 3. A safety component is provided. When the mounting bracket is detached from the wall, the safety connector can hold the entire speaker body, preventing the speaker body from falling and being damaged or injuring people.

[0021] 4. The safety connector is a steel rope, which is sturdy, reliable, and has a strong load-bearing capacity. Alternatively, the safety connector is a long spring, which, through its elastic tension, can prevent the wall-mounted speaker from being suddenly pulled upwards when it falls to its lowest position, thus avoiding damage from rigid impact or violent collision with the wall.

[0022] 5. The upper and lower ends of the mounting bracket are provided with thickened rubber plates to prevent the ends of the mounting bracket from being too thin and twisting.

[0023] 6. The screw holes of the bracket are formed by setting plugs, which can reduce the complexity and molding difficulty of the shell. Attached Figure Description

The bottom end of the head of the locking screw 123 presses against the annular boss 122 to form a seal, thus sealing the screw shaft even without a gasket, preventing it from contacting moisture and rusting.

[0038] In one embodiment, the mounting opening of the housing 11 covers the periphery of the faceplate 12, and a gap is provided between the inner wall of the mounting opening of the housing 11 and the periphery of the faceplate 12. The wall-mounted speaker also includes an aluminum mesh 13, which covers the outer side of the faceplate 12, and the periphery of the aluminum mesh 13 is inserted into the gap. The outer periphery of the mounting opening is provided with a pin hole 112, and a pin 14 is screwed in to lock the aluminum mesh 13, making the installation of the aluminum mesh 13 very firm and not easy to fall off.

[0039] The mounting bracket 2 is C-shaped in general, with both ends rotatably mounted to the upper and lower ends of the speaker body 1, and a flat wall-mounted seat formed in the middle. The wall-mounted seat is fixed to the wall by fastening screws, so that the wall-mounted speaker can be swung and has a high degree of flexibility.

[0040] In this embodiment, the mounting bracket 2 is installed in a concealed manner by inserting into the back of the speaker body 1. Two insertion slots 15 are provided on the upper and lower edges of the back of the speaker body 1. Screw holes are provided on the upper and lower edges near the back of the speaker body 1, and these screw holes pass through the two insertion slots 15 respectively. The two ends of the mounting bracket 2 are inserted into the two insertion slots 15 respectively, and are respectively screwed into the screw holes by a fixing stud.

[0041] Based on the above embodiments, to prevent the ends of the mounting bracket 2 from being too thin and twisted, thickened rubber plates 21 are provided at both the upper and lower ends of the mounting bracket 2. The thickened rubber plates 21 are installed on the outer surfaces of the upper and lower ends of the mounting bracket 2 and are provided with limiting grooves for the ends of the mounting bracket 2 to be inserted. A silicone pad 22 is provided between the inner surface of the end of the mounting bracket 2 and the speaker body 1. The silicone pad 22 has anti-slip textures on the side facing the speaker body 1 to prevent the wall-mounted speaker from being unable to be positioned.

[0042] Additionally, the thickened rubber plate 21 has a protruding post on the side opposite to the end of the mounting bracket 2. The end of the protruding post has a countersunk hole aligned with the screw hole of the bracket. The fixing stud passes sequentially through the countersunk hole, the hole at the end of the mounting bracket 2, the hole in the silicone pad 22, and the screw hole of the bracket. The upper and lower ends of the speaker body 1 have recesses near the back edge for the protruding post to protrude. The insertion slot 15 is trapezoidal.

The two ends of the protective connector are respectively connected to the two protective hooks 31. When the mounting bracket 2 is detached from the wall, the protective connector can suspend the entire speaker body 1, preventing the speaker body 1 from falling and causing damage or injury to personnel. In this embodiment, the protective connector is a steel rope, which is sturdy, reliable, and has a strong load-bearing capacity. Alternatively, in other embodiments, the protective connector is a long spring, which, through its elastic tension, can prevent the wall-mounted speaker from being damaged by rigid impact when it falls.

[0045] Based on the above embodiments, a tweeter 16 is installed inside the speaker body 1. The diaphragm of the tweeter 16 is made of silk dome and has a coaxial large dome and a small surround. The large dome and the small surround each have their own phase. From the perspective of sound wave propagation, the large dome is closer to the user, and the two cancel each other out and interfere with each other during propagation. Therefore, this utility model provides a pressing ring on the outer ring of the diaphragm. The pressing ring presses and covers half of the small surround, so that the sound propagation will avoid the blocked and pressed part and propagate forward, thereby adjusting the phase of the small surround so that it is closer to the large dome. In addition, the diaphragm of the tweeter 16 uses copper foil to directly lead out the wires, which has stronger adhesion and better stability.

[0046] In addition, a woofer 17 is installed inside the speaker body 1. The diaphragm of the woofer 17 uses copper foil to directly lead out the wires, resulting in stronger adhesion and better stability. The diaphragm of the woofer 17 is made of PP cone, which has waterproof and dustproof properties. Furthermore, the diaphragm of the woofer 17 has a structure that is thicker in the middle and gradually thins towards the periphery, allowing it to move evenly during vibration, resulting in more symmetrical vertical vibration and better tone.
