Description

Technical Field

[0001] This utility model relates to the field of audio technology, and in particular to an adjustable directivity and portable installation structure for audio equipment. Background Technology

[0002] In the field of audio equipment technology, the installation and directivity adjustment of indoor speakers are crucial to sound coverage. Directivity adjustment allows speakers to adjust the direction of sound propagation according to the needs of the scene, such as focusing on the audience area in a conference room or covering seats at different heights in an auditorium, thereby optimizing the sound field distribution.

[0003] Currently, most traditional audio equipment uses fixed installation, which leads to the following problems during use: 1. The angle adjustment of most devices is complicated, requiring tools or professional intervention, making it difficult for ordinary users to quickly adjust according to real-time needs; 2. Inaccurate angle control often occurs during the adjustment process, such as a lack of quantitative feedback when tilting or rotating horizontally. Users can only judge the sound coverage effect through repeated testing, which consumes a lot of time and energy. Therefore, we propose an adjustable directivity and portable installation structure for audio equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose an adjustable directivity and portable installation structure for audio equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable directivity and portable installation structure for an audio device includes a fixed plate fixedly installed on the ceiling of an indoor space. A support shaft is rotatably connected to the bottom of the fixed plate. A hollow support sphere is provided at the bottom of the support shaft. An arc-shaped opening is provided on the outer wall of the hollow support sphere. A mounting cylinder is slidably connected to the inner wall of the arc-shaped opening. An audio device body is fixedly installed on the inner wall of the mounting cylinder. A longitudinal adjustment mechanism capable of adjusting the longitudinal angle of the audio device body is provided on the inner wall of the hollow support sphere.

[0007] The longitudinal adjustment mechanism includes a drive motor fixedly installed on the inner side wall of the supporting hollow sphere. The output shaft of the drive motor is fixedly sleeved with an adjustment disc. The adjustment disc and the mounting cylinder are fixedly connected by two connecting rods.

[0008] Preferably, the arc-shaped opening, the drive motor, and the adjusting disc are arranged coaxially.

[0009] Preferably, the mounting cylinder and the arc-shaped opening are connected by a reinforcing mechanism, which includes two arc-shaped grooves formed on the inner wall of the arc-shaped opening. Two arc-shaped limiting plates are fixedly installed on the inner wall of the mounting cylinder, and the outer wall of the arc-shaped limiting plate on the same side and the inner wall of the arc-shaped groove are slidably connected.

[0010] Preferably, the two arc-shaped grooves are symmetrically arranged on the inner sidewall of the arc-shaped opening.

[0011] Preferably, the bottom of the fixed plate is provided with a horizontal adjustment mechanism that can adjust the lateral angle of the speaker body. The horizontal adjustment mechanism includes an adjustment rod rotatably connected to the bottom of the fixed plate. Gears are fixedly sleeved on the outer side walls of the support shaft and the adjustment rod, and the two gears are meshed together.

[0012] Preferably, an adjustment handle is fixedly installed at the end of the adjustment rod.

[0013] Preferably, the outer diameter of the gear sleeved on the support shaft is larger than the outer diameter of the gear sleeved on the adjusting rod.

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

[0015] Through the interaction of the fixed plate, support shaft, support hollow sphere, arc-shaped opening, mounting cylinder, speaker body, longitudinal adjustment mechanism, reinforcing mechanism, and transverse adjustment mechanism, the transverse and longitudinal adjustment mechanisms work together to achieve flexible adjustment of the speaker body's lateral and longitudinal angles, meeting the sound coverage requirements in different scenarios.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 An adjustable directional and portable installation structure for an audio device includes a fixed plate 1 fixedly installed on the ceiling of an indoor space. A support shaft 2 is rotatably connected to the bottom of the fixed plate 1. A hollow support sphere 3 is provided at the bottom of the support shaft 2. An arc-shaped opening 4 is provided on the outer wall of the hollow support sphere 3. An installation cylinder 5 is slidably connected to the inner wall of the arc-shaped opening 4. An audio body 6 is fixedly installed on the inner wall of the installation cylinder 5. A longitudinal adjustment mechanism capable of adjusting the longitudinal angle of the audio body 6 is provided on the inner wall of the hollow support sphere 3. The longitudinal adjustment mechanism includes a drive motor 7 fixedly installed on the inner wall of the hollow support sphere 3. An adjustment disc 8 is fixedly sleeved on the output shaft of the drive motor 7. The adjustment disc 8 and the installation cylinder 5 are fixedly connected by two connecting rods 9.

[0023] To further explain, the longitudinal angle of the speaker body 6 is adjusted by the longitudinal adjustment mechanism. Combined with the rotational connection between the supporting hollow sphere 3 and the fixed plate 1, multi-angle directional adjustment can be achieved. The sliding cooperation between the arc-shaped opening 4 and the mounting cylinder 5 not only ensures the stable support of the speaker, but also provides a structural basis for angle adjustment.

[0024] like Figure 1 and Figure 2 As shown, the arc-shaped opening 4, the drive motor 7, and the adjusting disc 8 are arranged coaxially.

[0025] To further explain, this design ensures uniform force transmission during adjustment, avoids adjustment jamming or structural wear caused by eccentricity, and improves adjustment accuracy and stability.

[0026] like Figure 1 and Figure 2 As shown, the mounting cylinder 5 and the arc-shaped opening 4 are connected by a reinforcing mechanism. The reinforcing mechanism includes two arc-shaped grooves 10 opened on the inner wall of the arc-shaped opening 4. Two arc-shaped limiting plates 11 are fixedly installed on the inner wall of the mounting cylinder 5. The outer wall of the arc-shaped limiting plate 11 on the same side and the inner wall of the arc-shaped groove 10 are slidably connected.

[0027] To further explain, the strengthening mechanism enhances the connection strength between the mounting cylinder 5 and the supporting hollow sphere 3 through the sliding fit between the arc-shaped groove 10 and the arc-shaped limiting plate 11, reduces the shaking of the speaker body 6 during the adjustment process, and improves the reliability of the overall structure.

[0028] like Figure 2 As shown, two arc-shaped grooves 10 are symmetrically arranged on the inner wall of the arc-shaped opening 4.

[0029] To further explain, this design ensures that the mounting cylinder 5 is subjected to balanced forces during sliding, which further improves the smoothness and stability of adjustment, while extending the service life of the structure.

[0030] like Figure 1 and Figure 4 As shown, the bottom of the fixed plate 1 is provided with a horizontal adjustment mechanism that can adjust the horizontal angle of the speaker body 6. The horizontal adjustment mechanism includes an adjustment rod 12 rotatably connected to the bottom of the fixed plate 1. Gears 13 are fixedly sleeved on the outer side wall of the support shaft 2 and the adjustment rod 12, and the two gears 13 are meshed together.

[0031] To further explain, the horizontal adjustment mechanism achieves the lateral angle adjustment of the speaker body 6 through gear 13 transmission. In conjunction with the vertical adjustment mechanism, it can achieve all-round directional adjustment to meet the sound coverage requirements in different scenarios.

[0032] like Figure 1 As shown, an adjustment handle 14 is fixedly installed at the end of the adjustment rod 12.

[0033] To further explain, the adjustment handle 14 allows operators to easily and manually adjust the lateral angle of the speaker without the need for tools, thus improving ease of use and flexibility.

[0034] like Figure 1 and Figure 4 As shown, the outer diameter of the gear 13 sleeved on the support shaft 2 is larger than the outer diameter of the gear 13 sleeved on the adjusting rod 12.

[0035] To further explain, this design creates a reduction gear ratio, making the adjustment process more precise and facilitating fine-tuning of the speaker body's 6-degree angle. It also increases the adjustment torque, making operation more effortless.

[0036] The functional principle of this utility model can be explained through the following operation methods:

[0037] 1. Horizontal angle adjustment (left and right direction)

[0038] Position the adjustment handle 14. Locate the adjustment handle 14 at the bottom of the fixed plate 1. Manually rotate the adjustment handle 14. Rotating the adjustment handle 14 clockwise will cause the speaker body 6 to rotate to the right. Rotating the adjustment handle 14 counterclockwise will cause the speaker body 6 to rotate to the left.

[0039] Note: Due to the gear 13 transmission design, the adjustment process is relatively smooth. When rotating, you need to pay attention to controlling the force to avoid over-adjustment.

[0040] Adjust to the target angle, and rotate the speaker body 6 to the required lateral angle (e.g., facing the audience area or a specific area) according to the sound coverage requirements.

[0041] Fine-tuning technique: Each rotation of the adjustment handle 14 results in a smaller rotation angle of the speaker body 6 (determined by the gear ratio of gear 13), facilitating precise directional control.

[0042] II. Vertical Angle Adjustment (Up and Down Direction)

[0043] Start the drive motor 7. Start the drive motor 7 inside the hollow sphere 3 (usually integrated into the equipment control system) via a power switch or remote control.

[0044] To control the pitch angle of the speaker body 6, after the drive motor 7 starts, the adjustment disc 8 rotates accordingly, and the mounting cylinder 5 slides along the arc-shaped opening 4 via the connecting rod 9. If the speaker body 6 needs to be tilted upward (pointing towards the ceiling), the drive motor 7 rotates forward, and the mounting cylinder 5 slides upward along the arc-shaped opening 4. If the speaker body 6 needs to be tilted downward (pointing towards the ground), the drive motor 7 rotates in reverse, and the mounting cylinder 5 slides downward along the arc-shaped opening 4.

[0045] Once the target angle is locked and reached, the drive motor 7 is turned off, and the braking device inside the drive motor 7 will automatically lock the adjustment position.

[0046] Note: The sliding fit between the arc-shaped groove 10 and the arc-shaped limiting plate 11 ensures a smooth adjustment process and a stable structure after locking, preventing it from shaking.

[0047] III. Examples of Multi-Angle Combination Adjustment

[0048] Cover the area in front

[0049] Lateral angle: Rotate the adjustment handle 14 until the speaker body 6 is facing the target area.

[0050] Vertical angle: Adjust the speaker body 6 downward by about 30°~45° using the drive motor 7 (adjust according to the installation height and coverage distance).

[0051] Covering the side area

[0052] Lateral angle: Rotate the adjustment handle 14 to tilt the speaker body 6 to the side by 45°~90°.

[0053] Vertical angle: Keep the speaker body level or slightly tilted downwards (approximately 10°~20°).

[0054] Wide coverage

[0055] First, adjust the horizontal angle of the speaker body 6 to the maximum deflection position (such as 90° on the left). Then, adjust the vertical angle using the drive motor 7 to cover different height areas. Repeat the above steps to adjust the speaker body 6 to the maximum deflection position on the right to complete the coverage of the entire area.

[0056] IV. Precautions

[0057] Operational safety: Avoid touching the surface of the speaker body 6 or the edge of the curved opening 4 during adjustment to prevent finger pinching. If the device is installed at a high place, it is recommended to use the remote control function to avoid climbing for adjustment.

[0058] Maintenance

[0059] Regularly clean the dust inside the arc-shaped opening 4 and arc-shaped groove 10 to ensure smooth sliding. Check the transmission parts of gear 13 every 6 months and add an appropriate amount of lubricating oil (if the design allows).

[0060] Load limit

[0061] The weight of the speaker body must not exceed the rated load of the equipment (usually indicated in the product manual), otherwise it may affect the adjustment accuracy or cause structural damage.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
