Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to a wire-limited speaker. Background Art

[0002] A speaker is a device that converts audio signals into sound. Its main working principle is that after the audio signal is input into the speaker, the electrical signal is converted into mechanical vibration through the speaker unit inside the speaker, thereby pushing the air to generate sound waves, and the sound is heard. Speakers are often used in some stage performances.

[0003] A Chinese patent, published under the publication number CN115426556A, discloses a speaker enclosure and a speaker comprising a main body, a cover, a knob, and a second snap-fit structure. Rotating the knob moves the second snap-fit structure, causing it to engage or dislocate with the first snap-fit structure, thereby locking or unlocking the cover. Furthermore, because the second snap-fit structure prevents the cover from moving relative to the main body when engaged with the first snap-fit structure, it prevents the cover from vibrating with the speaker enclosure, ensuring sound quality.

[0004] However, the above-mentioned speakers still have some problems. In actual applications, the wires will frequently rub and pull against other components inside the box due to vibration or external collision when the speaker is working, which can easily cause damage to the outer sheath of the wires or even internal breakage, shortening the service life of the wires. Therefore, a wire-limited speaker is proposed to address the above problems. Utility Model Content

The other output end of the dual-axis motor passes through the installation cavity and extends to the outside where a cleaning brush is installed. The cleaning brush contacts the top side of the air inlet, thereby achieving efficient heat dissipation inside the speaker while cleaning dust and debris in the air inlet, keeping the air inlet unobstructed.

[0008] Preferably, a plurality of heat dissipation holes are equidistantly provided inside one side of the box body, two mounting ears are symmetrically installed on the outer wall of one side of the box body, a rotating shaft is rotatably connected between the mounting ears, and a protective plate is installed on the outer wall of the rotating shaft, thereby reducing the interference of external dust and debris on the internal components of the speaker.

[0010] Preferably, two speakers are installed on the other side of the box, one end of the speaker is connected to a wire, one end of the wire has a wire inlet hole that passes through a wire groove and is led out from a wire outlet, keeping the internal structure of the speaker neat and beautiful.

[0011] Preferably, a control panel is installed on the other side of the box, and the control panel is used to control the operation of the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device and improving the convenience of operating the device.

[0012] The utility model is beneficial in that:

[0013] 1. One end of the wire of the utility model passes through the wire entry hole and enters the mounting frame. By rotating the threaded rod, the arc-shaped clamping plate can be pushed along the guide rod to clamp and fix the wire in the wire trough, ensuring the stable position of the wire, reducing the friction between the wire and other components, and extending the service life of the wire.

[0014] 2. When the angle of the protective plate needs to be adjusted, the slider can be operated. When the slider is slid in the slide groove, the protective plate is driven to rotate around the rotating axis through the connecting rod, thereby changing the degree of blocking of the heat dissipation holes by the protective plate, and playing a certain protective role for the heat dissipation holes, preventing foreign objects from directly entering the interior of the box through the heat dissipation holes and causing damage.

When the speaker 25 is connected to the wire, one end of the wire passes through the wire entry hole 8 into the mounting bracket 4, and finally, the wire is led out from the wire outlet 9. At this time, by rotating the threaded rod 5, the arc-shaped clamping plate 7 can be pushed to move along the guide rod 6, thereby clamping and fixing the wire inside the wire groove 2 to ensure the stable position of the wire. The equidistant circular grooves in the wire groove 2 and the balls 3 therein play a role in reducing friction and facilitating the smooth movement of the wire, thereby realizing the limit fixation of the wire, reducing the friction between the wire and other components, and extending the service life of the wire. After the wire is energized, the audio signal can be transmitted to the speaker 25, causing it to make a sound.

[0024] See also Figure 1 、 2As shown in , 4 and 5, a mounting cavity 10 is installed on the top side of the box body 1, and a plurality of air inlets 11 are opened inside the top side of the mounting cavity 10. A dual-axis motor 12 is installed inside the mounting cavity 10, and three fan blades 13 are fixedly installed on one output end of the dual-axis motor 12, and a cleaning brush 14 is installed on the other output end of the dual-axis motor 12; when the speaker is working, the heat inside the box body 1 will continue to accumulate. If the device works in a high temperature environment for a long time, its service life will be greatly shortened. When the dual-axis motor 12 is started, one output end thereof is fixedly mounted with three fan blades 13, and the other output end thereof is fixedly mounted with a cleaning brush 14. The fan blades 13 are driven to rotate in the box body 1. The rotation of the fan blades 13 will generate airflow. The airflow enters the box body 1 from the air inlet 11 and is discharged from the heat dissipation holes 15, taking away the heat inside the box body 1, thereby achieving heat dissipation and preventing the device from accumulating heat generated during operation, resulting in performance degradation or damage. At the same time, the output end of the other end of the dual-axis motor 12 drives the cleaning brush 14 to rotate outside the installation cavity 10. The cleaning brush 14 can continuously clean the dust on the top side of the air inlet 11, keep the air inlet 11 unobstructed, ensure a good amount of air intake, and thus maintain the heat dissipation effect.

[0025] See also Figure 2 、 3 As shown in FIG5 , a plurality of heat dissipation holes 15 are equidistantly provided inside one side of the box body 1, and two mounting ears 16 are symmetrically mounted on the outer wall of one side of the box body 1. A rotating shaft 17 is rotatably connected between the mounting ears 16, and a protective plate 18 is mounted on the outer wall of the rotating shaft 17;

[0026] A slide groove 19 is provided on one side of the box body 1, and a slider 20 is slidably installed inside the slide groove 19. A rotating pin 21 is installed on one side of the slider 20 and the protective plate 18. A connecting rod 22 is connected between the pins 21. Eight limiting holes 23 are equidistantly provided on one side of the box body 1, and a locking screw 24 is rotatably installed inside the slider 20. During operation, in actual application, external dust, debris, liquid, etc. may more easily enter the interior of the box body 1 through the heat dissipation holes 15, causing pollution, damage or short circuit to the internal electronic components, etc., seriously affecting the normal operation and service life of the speaker. To adjust the angle of the protective plate 18, you can operate the slider 20. When sliding the slider 20 in the slide groove 19, the protective plate 18 is driven to rotate around the rotating shaft 17 through the connecting rod 22, thereby changing the degree of blocking of the heat dissipation hole 15 by the protective plate 18. When the slider 20 moves to the appropriate position, the locking screw 24 is screwed into the corresponding limit hole 23 to fix the position of the slider 20, and then fix the angle of the protective plate 18. The protective plate 18 is in a state of covering the outside of the heat dissipation hole 15, which plays a certain protective role for the heat dissipation hole 15 and prevents foreign objects from directly entering the interior of the box 1 through the heat dissipation hole 15 and causing damage.

[0027] Working principle: when the speaker 25 is connected to the wire, one end of the wire passes through the wire inlet hole 8 and enters the mounting frame 4. Finally, the wire is led out from the wire outlet 9. At this time, by rotating the threaded rod 5, the arc-shaped clamping plate 7 can be pushed to move along the guide rod 6, thereby clamping and fixing the wire inside the wire trough 2 to ensure the stability of the wire position. The equidistant circular grooves in the wire trough 2 and the balls 3 therein play a role in reducing friction and facilitating the smooth movement of the wire, thereby achieving the limit fixation of the wire, reducing the friction between the wire and other components, and extending the service life of the wire. After the wire is energized, the audio signal can be transmitted to the speaker 25, causing it to emit sound.

[0028] The dual-axis motor 12 is started, and one output end thereof drives the fan blades 13 to rotate inside the housing 1. The rotation of the fan blades 13 generates airflow, which enters the housing 1 from the air inlet 11 and is discharged from the heat dissipation holes 15, taking away the heat inside the housing 1, thereby achieving heat dissipation and preventing the performance degradation or damage of the device caused by the accumulation of heat generated during operation. At the same time, the other output end of the dual-axis motor 12 drives the cleaning brush 14 to rotate outside the installation cavity 10. The cleaning brush 14 can continuously clean the dust on the top side of the air inlet 11, keeping the air inlet 11 unobstructed, ensuring a good amount of air intake, and thus maintaining the heat dissipation effect.

[0029] When the angle of the protective plate 18 needs to be adjusted, the slider 20 can be operated. When the slider 20 is slid in the slide groove 19, the protective plate 18 is driven to rotate around the rotating shaft 17 through the connecting rod 22, thereby changing the degree of blocking of the heat dissipation hole 15 by the protective plate 18. When the slider 20 moves to the appropriate position, the locking screw 24 is screwed into the corresponding limit hole 23 to fix the position of the slider 20, and then fix the angle of the protective plate 18. The protective plate 18 is in a state of covering the outside of the heat dissipation hole 15, which plays a certain protective role for the heat dissipation hole 15 and prevents foreign objects from directly entering the interior of the box 1 through the heat dissipation hole 15 and causing damage.
