[0033] To address the technical problem of existing speaker enclosures where the horn can be adjusted arbitrarily and cannot be quickly and accurately adjusted to the appropriate angle, this application specifically designs a speaker enclosure device. This device uses an adjustment mechanism to adjust the horn to a set angle and utilizes a positioning part to position a rotating disk or shaft to fix the horn in place. Please refer to the following for the structure and function of the speaker enclosure device of this application.

[0034] First Embodiment Figure 1 This is a front view structural schematic diagram of the speaker device according to the first embodiment of this application. Figure 2 This is a rear view structural diagram of the speaker device housing according to the first embodiment of this application. Figure 3 This is a cross-sectional view of the speaker device according to the first embodiment of this application along its width. Please refer to... Figures 1 to 3 The speaker assembly includes a housing 12, at least one speaker 13, and an adjustment mechanism 14. The at least one speaker 13 is movably connected to the housing 12. A rotating shaft 15 is fixed on the speaker 13. The adjustment mechanism 14 includes a positioning part 145. The rotating shaft 15 can adjust the pitch angle of the speaker 13 relative to the horizontal plane by rotation. The positioning part 145 is configured to position the rotating shaft 15 to fix the speaker 13 every time the rotating shaft 15 rotates by a set angle.

[0035] Optionally, Figure 4 This is a schematic diagram of the speaker angle after adjustment according to the first embodiment of this application, as shown below. Figure 4 As shown, the sound pressure emitted from the central axis O of the speaker 13 is the strongest. As the angle shifts, the sound pressure gradually decreases; for example, the sound pressure intensity at point A is higher than at point B, and the sound pressure intensity at point B is higher than at point C. When the human ear is at point C, the angle of the speaker 13 is adjusted by the adjustment mechanism 14, reducing the distance between the human ear and the central axis O of the speaker 13, thereby increasing the sound pressure. This application adjusts the pitch angle of the speaker 13 through an adjustment structure, reducing the distance between the central axis of the speaker 13 and the human ear, and improving the effect of the human ear in perceiving sound pressure.

[0036] The speaker device of this application can adjust the pitch angle of the speaker 13 through the adjustment mechanism 14. For example, the pitch angle of the speaker 13 can be adjusted by driving the rotating shaft 15 to rotate, which can improve the sound quality and reduce sound reflection interference. Moreover, the speaker 13 can be fixed by the positioning part 145 every time the rotating shaft 15 rotates by a set angle, that is, the speaker 13 rotates by the same angle each time. Therefore, the adjustment mechanism 14 of this application can quickly and accurately adjust the speaker 13 to the required pitch angle, which is convenient and efficient.

[0037] Optionally, the preset angle is 5° to 15°, that is, the rotating shaft 15 rotates 5° to 15° each time, for example, the preset angle of each rotation is 8°, 10°, and 12°; when the rotating shaft 15 rotates three times, the rotating shaft 15 rotates a total of 15° to 45°.

[0038] Optionally, the axis of the rotating shaft 15 is perpendicular to the central axis O of the horn 13, and the rotating shaft 15 is set through the central axis O of the horn 13. The back of the horn 13 is fixed to the rotating shaft 15, for example by welding or gluing.

[0039] Optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjustment mechanism 14 includes a rotating disk 142, at least one button 143, and at least one elastic element 144. The rotating disk 142 is fixed to the rotating shaft 15, and the button 143 is movably connected to the housing 12. The button 143 is linked to the rotating disk 142, and the elastic element 144 is connected between the button 143 and the housing 12. Pressing the button 143 can drive the rotating disk 142 and the rotating shaft 15 to rotate synchronously. The elastic element 144 is configured to drive the button 143 to reset by elasticity. In this embodiment, pressing the button 143 can drive the rotating disk 142 and the rotating shaft 15 to rotate synchronously. Each press can drive the rotating disk 142 and the rotating shaft 15 to rotate a preset angle, making the operation convenient and reliable.

[0040] Optionally, the rotating disk 142 is circular, and the rotating disk 142 is coaxially arranged with the rotating shaft 15.

[0041] Optionally, the rotating shaft 15 is cylindrical and has a protrusion. The rotating disk 142 has a mounting hole that mates with the rotating shaft 15. The wall of the mounting hole has a groove. The rotating shaft 15 passes through the mounting hole and the protrusion is placed in the groove. The relative movement between the rotating disk 142 and the rotating shaft 15 is prevented by the engagement of the protrusion and the groove.

[0042] Optionally, the rotating disk 142 includes a first surface 1421 and a second surface 1422 opposite to each other. The first surface 1421 is recessed to form at least two first steps 1423, and the second surface 1422 is recessed to form at least two second steps 1424. The button 143 includes a first drive arm 1431 and a second drive arm 1432. The first drive arm 1431 is disposed opposite to the first surface 1421, and the second drive arm 1432 is disposed opposite to the second surface 1422. The housing 12 is provided with at least one first guide wall 121 and at least one second guide wall 122. The first guide wall 121 is inclined toward the first surface 1421, and the second guide wall 122 is inclined toward the second surface 1422. When pressure is applied to button 143, the first drive arm 1431 moves along the first guide wall 121 and presses the first step 1423, and the second drive arm 1432 moves along the second guide wall 122 and presses the second step 1424. Button 143 pushes the rotating disk 142 to rotate through the first drive arm 1431 and the second drive arm 1432. Each time button 143 is pressed, the rotating disk 142 rotates by a set angle. When the pressure on button 143 is released, elastic element 144 drives button 143 to reset, and first drive arm 1431 and second drive arm 1432 open in a direction away from rotating disk 142.

[0043] Optionally, multiple first steps 1423 and multiple second steps 1424 are arranged sequentially around the circumference of the rotating disk 142, and each first step 1423 corresponds to each second step 1424. In this embodiment, the rotating disk 142 has, for example, three steps, namely three first steps 1423 and three second steps 1424. Each time the button 143 pushes the first step 1423 and the second step 1424, the rotating disk 142 rotates, for example, by 5° to 15°. If the button 143 pushes the first step 1423 and the second step 1424 three times, the rotating disk 142 rotates a total of 15° to 45°.

[0044] In other embodiments, the rotating disk 142 is provided with two, four or five steps. For example, when the rotating disk 142 is provided with two steps, the rotating disk 142 rotates 10° to 20° each time; for example, when the rotating disk 142 is provided with four or five steps, the rotating disk 142 rotates 3° to 10° each time, but is not limited thereto.

[0045] Optionally, the button 143 further includes a pressing base 1433, and the ends of the first drive arm 1431 and the second drive arm 1432 are fixed to the pressing base 1433. When the button 143 is in the unpressed state, the first drive arm 1431 and the second drive arm 1432 remain open, and the rotating disk 142 will not contact the first drive arm 1431 and the second drive arm 1432 when rotating. When the button 143 is gradually pressed, causing the button 143 to move into the housing 12, the first drive arm 1431 first contacts the first guide wall 121, and the second drive arm 1432 first contacts the second guide wall 122. During the movement of the button 143, the first guide wall 121 and the second guide wall 122 force the first drive arm 1431 to contact the second guide wall 122. 31 and the second drive arm 1432 gradually approach each other until the end of the first drive arm 1431 abuts against the first step 1423 and the end of the second drive arm 1432 abuts against the second step 1424. If the button 143 continues to move into the housing 12, the button 143 will push the rotating disk 142 to rotate until the button 143 moves to its limit position. When the pressure on the button 143 is released, the elastic element 144 drives the button 143 to reset, the first drive arm 1431 and the second drive arm 1432 cross the next first step 1423 and the next second step 1424, and the first drive arm 1431 and the second drive arm 1432 gradually return to the open state. At this time, pressing the button 143 again will repeat the above process.

[0046] Optionally, a funnel-shaped opening 13 is formed between the first guide wall 121 and the second guide wall 122, and the rotating disk 142 passes through the middle of the opening.

[0047] Optionally, the adjustment mechanism 14 includes two buttons 143 and two elastic elements 144. The two buttons 143 are respectively a first button 143 and a second button 144. The two elastic elements 144 are respectively configured to correspond to the first button 143 and the second button 143. The housing 12 is provided with two first guide walls 121 and two second guide walls 122 respectively configured to correspond to the first button 143 and the second button 143. The first button 143 is configured to drive the rotating disk 142 to rotate clockwise, and the second button 143 is configured to drive the rotating disk 142 to rotate counterclockwise. In this embodiment, the first button 143 is used to adjust the pitch angle of the horn 13, and the second button 143 is used to drive the horn 13 to reset.

In this embodiment, the driver 1452 is, for example, a servo motor. The driver 1452 is used to drive the rotating disk 142 and the rotating shaft 15 to rotate, thereby automatically adjusting the pitch angle of the horn 13.

[0067] Optionally, the preset angle is 5° to 15°, and the driver 1452 drives the rotating disk 142 and the rotating shaft 15 to rotate by an angle of 5° to 15° each time.

[0068] Optionally, the speaker assembly also includes a control switch (not shown), which is electrically connected to the driver 1452 and the controller, respectively. The control switch is configured to control the driver 1452 and the controller to start or stop. When the control switch is triggered, the driver 1452 is energized and starts, at which time the driver 1452 drives the rotating disk 142 and the rotating shaft 15 to rotate by a set angle; when the control switch is triggered again, the driver 1452 is energized and starts, and the driver 1452 again drives the rotating disk 142 and the rotating shaft 15 to rotate by the set angle; the number of times the control switch is triggered is equal to the number of times the controller drives the rotating disk 142 and the rotating shaft 15 to rotate.

[0069] Optionally, the edge of the rotating disk 142 is provided with driven teeth (not shown), and the output end of the driver 1452 is provided with a driving gear, which meshes with the driven teeth. In this embodiment, a portion of the edge of the rotating disk 142 extends out from the clearance hole 301 of the housing 12, and the edge of the rotating disk 142 located inside the housing 12 is provided with driven teeth.

[0070] Optionally, the adjustment mechanism 14 also includes a sensor (not shown) for detecting the rotation angle of the shaft 15. The sensor is electrically connected to the driver 1452. When the sensor detects that the shaft 15 has rotated to a set angle, the driver 1452 stops driving.

[0071] In other embodiments, the driver 1452 can be linked to the rotating shaft 15 via the connecting rod 1453, and the driver 1452 is used to drive the rotating shaft 15 to rotate.

[0072] Optionally, each of the two horns 13 has a fixed rotating shaft 15 on its back. The driver 1452 can be connected to the two rotating shafts 15 respectively via two connecting rods 1453. Alternatively, each rotating shaft 15 may have a rotating disk 142, and the driver 1452 may mesh with the driven teeth of the two rotating disks 142 respectively via a gear assembly.
