Description

Technical Field

[0001] The present application relates to the field of audio technology, and in particular to an adjustable directional audio system. Background Art

[0002] Directional sound is also called sound gathering treasure, directional speaker, directional speaker, directional loudspeaker, ultrasonic directional sound, directional speaker, etc. The sound emitted by directional sound can be transmitted in a direction, so that the sound is emitted and transmitted like a flashlight beam. It is often used in exhibitions, education, digital signage, various self-service terminals, transportation and other scenes. Directional sound can accurately locate the sound playback area to avoid sound interference and improve the communication effect and viewing of advertising information. Directional sound is divided into wired and wireless. Wired sound transmits and transports sound through lines. It has the advantages of less damage to sound during transportation, higher sound retention and lower distortion.

[0003] Existing wired directional speakers generally have multiple connection ports, which are used to connect to power supplies and devices such as computers and mobile phones. Most of these connection ports are exposed on the side of the directional speaker that is away from the hole surface. When the directional speaker is in use, dust and impurities are easy to enter the unused ports, which can easily cause poor contact. Dust plugs are often used in the prior art to seal the connection ports to prevent dust from entering the interior of the connection ports. However, the dust plugs are easy to fall off and get lost during use, and the protection effect on the connection ports is poor. In order to reasonably improve this problem, the present application proposes an adjustable directional speaker. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 6 As shown, an adjustable directional speaker proposed in one embodiment of the present application includes a speaker box 1 and a supporting leg 2 connected to the bottom thereof, which are all prior art, and also include:

[0027] A connecting rod 3 is provided at the bottom of the sound box 1, the axis of the connecting rod 3 is perpendicular to the sound box 1, a through groove 4 is coaxially constructed inside the connecting rod 3, and the top of the through groove 4 is connected to the inside of the sound box 1, a mounting block 5 is installed at the bottom of the connecting rod 3, the mounting block 5 is coaxial with the connecting rod 3, and its outer diameter is larger than the outer diameter of the connecting rod 3, and a plurality of connecting ports 6 are distributed in a ring around the circumference, and the plurality of connecting ports 6 are respectively a power connection port 6 for connecting a power line, an audio line connection port 6 for connecting a computer, and a data line connection port 6 for connecting different devices such as Android and Apple mobile phones. It should be specifically explained here that the total number of the connecting ports 6 is an odd number, and the connecting wires of the plurality of connecting ports 6 are electrically connected to the inside of the sound box 1 through the through groove 4;

[0028] The circular plate 7 is connected to the bottom of the mounting block 5, and its outer diameter is larger than the outer diameter of the mounting block 5. The top of the mounting block 5 is provided with an annular block 8, which is slidably matched with the connecting rod 3. The annular block 8 is coaxial with the connecting rod 3, and the outer diameter is consistent with the outer diameter of the circular plate 7. Two concentric annular grooves 9 are provided at the bottom of the annular block 8. The inner diameter of the annular groove 9 located on the inner side is larger than the outer diameter of the mounting block 5, and the first shielding plate 10 and the second shielding plate 11 are slidably matched therein, respectively. The outer arc surface of the second shielding plate 11 is in sliding contact with the inner arc surface of the first shielding plate 10. The second shielding plate 11 is provided with a push block 12, and the second shielding plate 11 can be driven in the inner annular groove by pushing the push block 12. 9, when the arc inner sides of the first shielding plate 10 and the second shielding plate 11 are opposite to each other, the first shielding plate 10 and the second shielding plate 11 can shield the installation block 5, and after the annular block 8 is driven to slide upward, the peripheral connection port 6 of the installation block 5 can be exposed, and then the power cord and the equipment line connector can be connected to the connection port 6, and then the first shielding plate 10 and the second shielding plate 11 can be driven to rotate so that the two are staggered with each other, and when the annular block 8 is pushed to slide downward, the power cord and the equipment line connector can be accommodated by adjusting the opening exposed by the first shielding plate 10 and the second shielding plate 11, so that the unused connection port 6 can be protected and the entry of dust and impurities can be reduced;

[0029] The present application adopts a matching design of a first baffle plate 10 and a second baffle plate 11. When not in use, all the sockets on the side of the mounting block 5 can be blocked to reduce the entry of dust and impurities. When in use, the first baffle plate 10 and the second baffle plate 11 can be rotated to adjust their positions. The opening formed by the staggered position of the two can accommodate the power cord and the device line connector connected to the connection port 6, so as to protect the unused connection port 6 and reduce the entry of dust and impurities. By adopting an adjustable design, the protection effect of the connection port 6 is better than that of the prior art, and the application is practical.

[0030] like Figure 2-Figure 6As shown, in some embodiments, the first baffle plate 10 includes two first arc-shaped plates 1001, the two first arc-shaped plates 1001 are independent of each other, and are both slidably disposed in the outer annular groove 9, the second baffle plate 11 includes two second arc-shaped plates 1101, the two second arc-shaped plates 1101 are independent of each other, and are both slidably disposed in the inner annular groove 9, there are two push blocks 12, which are vertically arranged and respectively constructed at the ends of the second arc-shaped plates 1101, and the back sides of the push blocks 12 respectively contact and overlap with the opposite ends of the two first arc-shaped plates 1001, and the two first arc-shaped plates 1001 and the two second arc-shaped plates 1101 are distributed in an interval and staggered manner. With such a design, when the angle between the power cord connected to the connecting port 6 and the equipment cord connector is large, the two first arc-shaped plates 1001 and the two second arc-shaped plates 1101 can be driven to slide, and the exposed connecting port 6 within the angle can be shielded by the first arc-shaped plate 1001 or the second arc-shaped plate 1101.

[0031] like Figure 2-Figure 5 As shown, in some embodiments, a cylindrical groove 13 is provided at the bottom of the sound box 1, the connecting rod 3 is disposed in the cylindrical groove 13, the connecting rod 3 is coaxial with the cylindrical groove 13, the annular block 8 is slidably matched with the cylindrical groove 13, and when the annular block 8 is driven to slide upward, the annular block 8 can enter the cylindrical groove 13, and the annular block 8 is accommodated by the cylindrical groove 13, so that the structure of the device is more compact, thereby effectively reducing the space occupied by the device.

[0032] like Figure 2-Figure 5 As shown, in some embodiments, an annular groove 14 is provided at the top of the annular block 8, in which a compression spring 15 is provided, and the top of the compression spring 15 is in conflict with the cylindrical groove 13. The compression spring 15 is used to provide a thrust forcing the annular block 8 to move away from the cylindrical groove 13. Under the action of this thrust, the annular block 8 can drive the first arc plate 1001 and the second arc plate 1101 to contact the top of the circular plate 7. Such a design makes it difficult for the annular block 8 to slide on the connecting rod 3 under the action of the compression spring 15 when the equipment is transported, so that the first arc plate 1001 and the second arc plate 1101 are not easy to collide with the circular plate 7, so that the first arc plate 1001 and the second arc plate 1101 are not easy to be deformed and damaged, and the service life of the device can be extended.

[0033] like Figure 2-Figure 5As shown, in some embodiments, an annular magnet 16 is installed on the top of the annular block 8, and a magnetic plate 17 is installed in the cylindrical groove 13. The magnetic plate 17 is a stainless steel plate. The annular magnet 16 is magnetically connected to the magnetic plate 17. It should be specifically noted here that the magnetic force of the annular magnet 16 is greater than the thrust provided by the compression spring 15. When the annular block 8 slides upward, the annular magnet 16 contacts the magnetic plate 17 and is adsorbed thereon. At this time, the compression spring 15 cannot push the annular block 8 to slide downward, so as to connect the power cord and the equipment line connector to the connection port 6. After completing the connection and adjusting the positions of the first arc plate 1001 and the second arc plate 1101, the annular block 8 can be pushed downward to separate the annular magnet 16 from the magnetic plate 17. At this time, the annular block 8 can slide downward on the compression spring 15.

[0034] like Figure 3 As shown, in some embodiments, the annular block 8 is constructed with annular protrusions 18 on its circumference, and there are multiple annular protrusions 18 in a linear array along the axis of the annular block 8. The annular protrusions 18 can increase the roughness of the annular block 8 on its circumference, making it easier to push it to slide up and down.

[0035] like Figure 2-Figure 4 As shown, in some embodiments, the connecting rod 3 is rotatably installed in the cylindrical groove 13, and the connecting rod 3 is cylindrical. With such a design, after the power cord and the device line connector are connected to the connecting port 6, the direction of the power cord and the device line connector can be adjusted by rotating the connecting rod 3 so that it faces away from the hole surface of the sound box 1 to facilitate the arrangement of the device line.

[0036] like Figure 5 As shown, in some embodiments, the mounting block 5 is a prism block, and multiple connection ports 6 are respectively installed on multiple side faces 19 thereof. In the present application, the mounting block 5 is preferably a regular heptagonal prism, and its side faces 19 are relatively flat, which facilitates the connection between the power cord and the equipment cord connectors and the connection ports 6.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
