Description

Technical Field

[0001] The utility model specifically relates to a directional sound source speaker with a controllable propagation area, belonging to the technical field of speakers. Background Technique

[0002] The working principle of a directional sound source speaker is based on the physical properties and acoustic principles of sound waves. It mainly utilizes the interference and superposition phenomena of sound waves under specific conditions, as well as the directivity characteristics of sound waves to achieve the directional propagation of sound. When two or more sound waves meet in the same space, they will interfere with each other. If the parameters such as the frequency, amplitude, and phase of these sound waves meet certain conditions, they will superpose on each other to form a stronger sound wave. The directional speaker makes the sound waves interfere and superpose in a specific direction by carefully designing the sound source and reflection structure, thereby enhancing the sound pressure in that direction.

[0003] Existing directional sound source speakers are usually used in places such as exhibition halls and science and technology museums. Generally, a directional sound source speaker can give people a feeling of whispering in the ear. However, when existing directional sound source speakers are in use, they usually direct the sound to a certain area, but it is not convenient for staff to adjust the directional sound source speaker at multiple angles, and the adjustability is poor. Moreover, when adjusting the sound direction, the existing device is not convenient to visually replace the sound, and it is not convenient for staff to accurately adjust the sound direction.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Clamping grooves are uniformly formed on the circumferential inner surface of the fixing ring, and the clamping tapered rod is slidably clamped with the clamping grooves.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 6 As shown, a directional sound source speaker with a controllable propagation area includes a mounting plate 1. A horizontal rotation assembly 2 is provided on the lower surface of the mounting plate 1. The horizontal rotation assembly 2 includes a rotating disk 201 and a fixed ring 202.

The lower end of the support frame 501 is fixedly installed with a sound collection cover 6. A directional sound source speaker body 7 is provided inside the sound collection cover 6. A ring cover 9 with an irradiation lamp 8 on its lower surface is sleeved on the outer surface of the lower end of the sound collection cover 6.

[0025] As Figure 2 and Figure 3As shown in the figure, the horizontal rotation assembly 2 includes a hub motor 203, which is embedded inside the rotating disk 201. The upper end of the hub motor 203 is fixedly connected to the mounting plate 1. The fixing ring 202 is sleeved on the outer surface of the rotating disk 201, and the fixing ring 202 is fixedly connected to the mounting plate 1. An annular T-shaped block 204 is fixedly installed on the circumferential outer surface of the rotating disk 201. An annular groove is formed on the circumferential inner surface of the fixing ring 202, and the annular T-shaped block 204 is slidably clamped with the annular groove. A spring groove is formed on the circumferential outer surface of the rotating disk 201. A clamping spring 205 is arranged in the spring groove. One end of the clamping spring 205 is fixedly installed with a clamping tapered rod 206. Clamping grooves 207 are evenly formed on the circumferential inner surface of the fixing ring 202. The clamping tapered rod 206 is slidably clamped with the clamping grooves 207. A sound switch 10 is arranged in the clamping groove 207. A buzzer mechanism 11 is fixedly installed on the lower surface of the mounting plate 1. The sound switch 10 is electrically connected to the buzzer mechanism 11. So that after the staff adjusts the direction of the directional sound source speaker body 7 through the longitudinal angle adjustment assembly 5, at this time, the staff can turn on the power of the hub motor 203, so that the hub motor 203 drives the rotating disk 201 to rotate, and drives the sound collecting cover 6 to rotate through the rotation of the rotating disk 201, thereby being able to adjust the angle of the directional sound source speaker body 7. At the same time, when the clamping tapered rod 206 impacts the sound switch 10 under the action of the clamping spring 205, at this time, through the electrical connection between the sound switch 10 and the buzzer mechanism 11, it can make the rotating disk 201 emit a reminder sound when rotating a certain angle, and the sound switch 10 in the clamping groove 207 will make the buzzer mechanism 11 emit different sounds, similar to the principle of a music calculator. Since the above is the prior art, no structural description is made for this device, which is convenient for the staff to adjust later.

The internal thread 14 is rotatably engaged with the external thread 13. The irradiation lamps 8 are evenly embedded on the lower circumferential surface of the ring cover 9. So that when the staff turns on the power supply of the driving motor 504, at this time, the staff drives the driving gear 503 to rotate through the driving motor 504. The angle adjustment gear 502 can be driven to rotate through the driving gear 503. The rotation of the angle adjustment gear 502 can drive the rotation of the fixed disk 505. The support frame 501 can be driven to rotate through the fixed disk 505. At this time, under the clamping of the balls 507 on the stable disk 506 and the ball groove on one side of the concave frame 4, the support frame 501 can rotate stably. Then the support frame 501 can drive the sound collecting cover 6 to rotate. At this time, the longitudinal angle of the directional sound source speaker body 7 is adjusted. And through the provided irradiation lamps 8, the propagation direction of the sound can be visualized, thereby facilitating the staff to adjust the sound.
