Description

Technical Field

[0001] This utility model relates to the field of directional sound generation technology, specifically to an integrated directional sound generation device. Background Technology

[0002] A directional sound-emitting screen is a type of directional loudspeaker. It includes an upper wire and a lower wire that are attached to a frame. Each of the upper and lower wires is plated with a conductive layer, which serves as positive and negative electrodes, respectively. When energized, the upper wire vibrates under the action of an alternating voltage, thereby blasting air to produce sound.

[0003] However, existing directional sound panels and amplifier boxes are separate units, which require more space to use, have more wiring, appear less neat, and have a limited range of uses.

[0004] Therefore, a solution needs to be studied to address the problems of directional sound-emitting screens, such as large space occupation, messy wiring, and limited usage. Utility Model Content

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0030] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprising" shall be understood to include the stated elements or components without excluding other elements or other components.

[0031] like Figures 1 to 8 As shown, the integrated directional sound-emitting screen disclosed in this utility model mainly includes a directional sound-emitting screen 1, a connecting rod 2, and a drive box 3. Each side of the directional sound-emitting screen 1 is connected to the side of the drive box 3 through a connecting rod 2.

[0032] Specifically, in this embodiment, as Figure 2 As shown, the directional sound-emitting screen 1 includes a screen body 11 and a cover. The cover specifically includes a front cover 12 and a rear cover 13 that fit together, with the screen body 1 sandwiched between the front cover 12 and the rear cover 13. The cover has a hollow portion 14 in the middle, within which the screen body 11 is encapsulated and protrudes from the hollow portion 14. In this embodiment, the directional sound-emitting screen is a fully transparent electrostatic ultrasonic transducer; however, it can also be opaque. Its specific structure and sound-emitting principle can be referenced from existing electrostatic ultrasonic transducers, and this utility model will not elaborate further.

[0033] The side end of the directional sound-emitting screen 1 is detachably and rotatably connected to one end of the connecting rod 2. Specifically, in this embodiment, each side end of the directional sound-emitting screen 1 is provided with an outwardly extending first rotating shaft 21, which extends outward from both sides of the cover. One end of the connecting rod 2 is sleeved on the first rotating shaft 21, and its axial movement is restricted by a retaining spring 22, that is, the first rotating shaft 21 and one end of the connecting rod 2 are axially limited by the retaining spring 22. The directional sound-emitting screen 1 can rotate around the first rotating shaft 21 from 0° to 360°, that is, its orientation can be adjusted to face forward, face backward, tilt forward, tilt backward, face upward, face downward, etc., so as to meet the usage needs of different directions and different heights, such as... Figure 1 and Figures 3-5 As shown. In addition to being mounted on the connecting rod 2, the directional sound-emitting screen 1 can also be detached from the connecting rod 2 for independent use. After detachment, it can be attached to any flat surface, improving its flexibility and greatly expanding its application scenarios and scope. Furthermore, the directional sound-emitting screen is connected to the driver box via electrical cables, with at least some of the cables routed within the connecting rod, resulting in a clean and aesthetically pleasing overall appearance. Figure 8 As shown.

[0034] In this embodiment, as Figure 2 As shown, the driver box 3 specifically includes a driver cover, a function board located within the driver cover, and at least one omnidirectional speaker 31. The function board specifically includes an amplifier board 32, a microphone board 33, and a button board 34. The driver cover specifically includes an upper cover 35 and a lower cover 36 that fit together, forming an accommodating space within which the amplifier board 32, microphone board 33, and omnidirectional speaker 31 are located. The amplifier board 32 is electrically connected to the directional sound-emitting screen 1. The audio signal is processed and amplified by the amplifier board 32 and then emitted directionally by the directional sound-emitting screen 1. The microphone board 33 is electrically connected to the amplifier board 32, and the sound signal it picks up is also processed and amplified by the amplifier board 32 before being output. The omnidirectional speaker 31 is also electrically connected to the amplifier board 32. The audio signal is processed and amplified by the amplifier board 32 and can be emitted by the omnidirectional speaker 31 and / or the directional sound-emitting screen 1. At least one button on the button panel 34 is the power button 4, which is exposed on the drive cover. The power button 4 is used to start the drive box 3 and the directional sound-emitting screen 1. This invention combines the omnidirectional speaker 31 with the directional sound-emitting screen 1, which can compensate for the low and mid-frequency sounds of the directional sound-emitting screen 1, improving its sound quality and listening experience, and enhancing the listener's auditory experience. Furthermore, this invention combines a microphone with the directional sound-emitting screen 1, enabling the directional sound-emitting screen 1 to achieve both sound pickup and directional sound emission.

[0035] The side end of the drive box 3 is rotatably connected to the other end of the connecting rod 2. Specifically, in this embodiment, the side end of the drive box 3 is connected to the other end of the connecting rod 2 via a second rotating shaft 37 and a connector 38. The second rotating shaft 37 is a damping rotating shaft, which is connected to the other end of the connecting rod 2 via the connector 38. In this embodiment, the other end of the connecting rod 2 can rotate from 0° to 180° around the second rotating shaft 37. That is, by adjusting the angle of the connecting rod 2 relative to the drive box 3, the height of the directional sound-emitting screen 1 relative to the drive box 3 can be adjusted. For example, the connecting rod 2 can be adjusted to be perpendicular to the drive box 3, or it can be adjusted to be horizontal to the drive box 3, or the connecting rod 2 can be adjusted to be tilted backward relative to the drive box 3 (e.g., ...). Figure 6 As shown), or, for example, the connecting rod 2 can be adjusted to tilt forward relative to the drive box 3 (as shown). Figure 7 (as shown). Furthermore, in these positions, the orientation of the directional sound-emitting screen 1 can be adjusted via the first rotating shaft 21.

[0036] The advantages of this utility model are as follows: 1. This utility model connects the directional sound-emitting screen 1 and the driver box 3 through a connecting rod, realizing the integrated use of the directional sound-emitting screen 1. It is easy to install and use, and the connecting wires are run inside the connecting rod 2, making the overall appearance simple and beautiful. In addition, the detachable connection between the directional sound-emitting screen 1 and the connecting rod 2 allows it to be used alone or mounted on the connecting rod 2, improving its flexibility and greatly expanding its application scenarios and scope. 2. This utility model allows for the rotatable connection between the directional sound-emitting screen 1 and the connecting rod 2, as well as between the driver box 3 and the connecting rod 2, making the orientation and angle of the directional sound-emitting screen 1 adjustable, suitable for use by people of different orientations and heights. 3. This utility model combines the omnidirectional speaker 31 with the directional sound-emitting screen 1 to compensate for the low and mid-frequency sound of the directional sound-emitting screen 1, thereby improving the sound quality and listening experience of the directional sound-emitting screen 1 and enhancing the listening experience of the audience; in addition, this utility model also combines the microphone with the directional sound-emitting screen 1, enabling the directional sound-emitting screen 1 to achieve sound pickup and directional sound emission.
