Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to an angle-adjustable loudspeaker. Background Technology

[0002] A loudspeaker, also known as a "horn," is a common energy conversion device that transforms electrical signals into sound signals. The function of a loudspeaker is to make sound travel farther and louder. When a loudspeaker is working, the sound signal is converted into an electrical signal, which is then amplified by a power amplifier and converted back into a sound signal for playback.

[0003] The placement angle of a loudspeaker directly affects the direction of sound wave radiation and the sound pressure distribution in the listening area. Traditional fixed-angle loudspeakers struggle to optimize sound field directivity for different usage scenarios, thus limiting the optimal listening area. Summary of the Invention

[0004] In view of the above-mentioned technical problems in the existing technology, the present invention provides an angle-adjustable speaker.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An angle-adjustable loudspeaker is provided, including a mounting plate, a movable plate, and a loudspeaker body. The movable plate and the mounting plate are hinged together by a hinge. The loudspeaker body is connected to the movable plate. A first rotating block is provided at the end of the loudspeaker body. A rotating mechanism is also provided on the movable plate. The loudspeaker body is rotatably connected to the moving mechanism on the movable plate through the first rotating block. The rotation direction of the loudspeaker body relative to the movable plate is different from the rotation direction of the movable plate relative to the mounting plate.

[0007] Preferably, the rotating mechanism includes two protrusions arranged vertically, each protrusion having a mounting hole, the two mounting holes being coaxially arranged, and the two ends of the first rotating block being inserted into the two mounting holes respectively.

[0008] Preferably, the rotating mechanism further includes a mounting base, which is located at the top of the upper protrusion or at the bottom of the lower protrusion. A stepper motor is fixedly installed inside the mounting base, and the output shaft of the stepper motor passes through one of the mounting holes and is connected to one end of the first rotating block that passes through the mounting hole.

[0009] Preferably, a limiting rod is also fitted on the output shaft of the stepper motor, and the limiting rod can rotate as the output shaft of the stepper motor rotates.

[0010] Preferably, the mounting plate is also provided with a support member, which is used to support the movable plate after the movable plate is rotated to a specified angle by the hinge member; one end of the support member is hinged to the mounting plate, and the other end of the support member abuts against the back of the movable plate.

[0011] Preferably, the support is a telescopic rod, which includes a first rod body and a second rod body. The first rod body passes through the second rod body and can move axially along the second rod body. The other end of the second rod body is hinged to the mounting plate, and the other end of the first rod body connected to the second rod body abuts against the back of the movable plate.

[0012] Preferably, the back of the movable plate has multiple wedge-shaped grooves, which are arranged along the height direction of the movable plate, and the other end of the first rod connecting the second rod has a wedge-shaped surface that matches the wedge-shaped grooves.

[0013] Preferably, the hinge is a hinge, which includes a male leaf, a female leaf and a pin. The male leaf is connected to a fixed plate, the female leaf is connected to a movable plate, and the pin is inserted into the hinge between the male leaf and the female leaf.

[0014] The beneficial effects of this utility model are:

[0015] This utility model discloses an angle-adjustable speaker. Because the movable plate and the mounting plate are hinged together, the movable plate can be angle-adjusted relative to the mounting plate, providing a basic dimension for overall speaker angle adjustment. The speaker body is rotatably connected to a rotating mechanism on the movable plate via a first rotating block, and the direction of rotation of the speaker body relative to the movable plate differs from the direction of rotation of the movable plate relative to the mounting plate. This forms a two-dimensional angle adjustment. This design makes it easier for users to adjust according to actual conditions, optimizing the ratio of direct sound to reflected sound through fine-tuning the angle, thereby further improving the clarity and layering of audio playback.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment provides an angle-adjustable speaker, such as... Figures 1 to 5 As shown, the system includes a mounting plate 1, a movable plate 2, and a speaker body 3. The movable plate 2 is hinged to the mounting plate 1 via a hinge joint, allowing the movable plate 2 to rotate relative to the mounting plate 1 at a certain angle, thus providing a basis for adjusting the angle of the entire speaker. The speaker body 3 is connected to the movable plate 2, and a first rotating block 30 is provided at one end of the speaker body 3. The movable plate 2 also has a rotating mechanism 20. The speaker body 3 is rotatably connected to the rotating mechanism 20 on the movable plate 2 via the first rotating block 30, allowing the speaker body 3 to rotate relative to the movable plate 2.

[0024] In this design, the movable plate 2 rotates relative to the mounting plate 1 in a first direction, while the speaker body 3 rotates relative to the movable plate 2 in a second direction. Specifically, the movable plate 2 rotates back and forth relative to the mounting plate 1, while the speaker body 3 rotates left and right relative to the movable plate 2. This design provides greater flexibility in angle adjustment, allowing users to precisely adjust the speaker's sound direction from multiple dimensions according to their actual needs, thereby effectively improving the speaker's user experience and applicability.

[0025] The hinge component employs a hinge 5 structure, comprising a male leaf 50, a female leaf 51, and a pin 52. The male leaf 50 is fixedly connected to the mounting plate 1, while the female leaf 51 is connected to the movable plate 2. The male leaf 50 and female leaf 51 form a hinged connection through a specific design, and the pin 52 is inserted at the hinge point between them, enabling a rotatable connection. This hinge structure allows the movable plate 2 to adjust its angle relative to the mounting plate 1, using the pin 52 as its rotation axis. The fixed connection between the male leaf 50 and the mounting plate 1, and between the female leaf 51 and the movable plate 2, ensures the stability of the hinge 5 structure during rotation, making the movable plate 2 both flexible and secure when adjusting its angle.

[0026] Furthermore, the rotating mechanism 20 includes two protrusions 200 arranged vertically. Each protrusion 200 has a mounting hole 201, and the two mounting holes 201 are coaxially aligned. The first rotating block 30 at the end of the speaker body 3 is inserted into the two mounting holes 201 at its two ends. This engagement method realizes the rotational connection between the speaker body 3 and the movable plate 2, providing a stable rotational structural basis for adjusting the angle of the speaker body 3 relative to the movable plate 2.

[0027] Furthermore, the rotating mechanism 20 also includes a mounting base 202, which can be selectively disposed on the top of the upper protrusion 200 or the bottom of the lower protrusion 200. A stepper motor 203 is fixedly mounted inside the mounting base 202. The output shaft of the stepper motor 203 passes through one of the mounting holes 201 and is connected to one end of the first rotating block 30, which also passes through the mounting hole 201. This design allows the first rotating block 30 to rotate by controlling the operation of the stepper motor 203, thereby achieving precise adjustment of the angle of the speaker body 3 relative to the movable plate 2, meeting the diverse needs of users for different sound emission directions.

[0028] In addition, a limiting rod 204 is fitted onto the output shaft of the stepper motor 203. This limiting rod 204 can rotate synchronously with the rotation of the output shaft of the stepper motor 203. The limiting rod 204 limits the rotation angle range of the first rotating block 30, effectively preventing problems such as internal wiring pulling and component damage caused by excessive rotation of the speaker body 3. While ensuring the speaker angle adjustment function, it also improves the safety and stability of the equipment.

[0029] Furthermore, a support member is provided on the mounting plate 1. This support member is used to support the movable plate 2 after it has been rotated to a specified angle via a hinge. Specifically, one end of the support member is hinged to the mounting plate 1, and the other end abuts against the back of the movable plate 2, forming a stable triangular support structure. When the movable plate 2 rotates relative to the mounting plate 1 to the target angle, the support member restricts the movable plate 2 from continuing to rotate through its abutment action, thereby maintaining the stable operation of the speaker body 3 at that angle.

[0030] Furthermore, the support component is a telescopic rod 4, which includes a first rod body 40 and a second rod body 41. The first rod body 40 passes through the second rod body 41 and can move axially along the second rod body 41 to adjust the length of the telescopic rod 4. One end of the second rod body 41 is hinged to the mounting plate 1, and the other end, where the first rod body 40 connects to the second rod body 41, abuts against the back of the movable plate 2. By adjusting the length of the telescopic rod 4, the support requirements of the movable plate 2 at different rotation angles can be accommodated, ensuring that the support component always maintains effective contact with the back of the movable plate 2.

[0031] Furthermore, the back of the movable plate 2 is provided with multiple wedge-shaped grooves 21, which are arranged along the height direction of the movable plate 2. Simultaneously, the end of the first rod 40 that abuts against the back of the movable plate 2 has a wedge-shaped surface that matches the wedge-shaped grooves 21. When the movable plate 2 rotates to a specified angle, the wedge-shaped surface of the telescopic rod 4 can be embedded into the corresponding wedge-shaped groove 21. The self-locking effect of the wedge structure enhances the support stability and prevents the movable plate 2 from shifting angle due to external vibration or its own weight. The multiple wedge-shaped grooves 21 allow the movable plate 2 to achieve angle locking at different height positions, further improving the flexibility of speaker angle adjustment and support reliability.
