Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker which is convenient for adjusting direction. Background Art

[0002] A loudspeaker is a device that amplifies and diffuses sound. Its history can be traced back to the end of the 19th century. In 1877, Edison invented the first record player. The principle of the loudspeaker is actually a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the speaker will move forward or backward. Because the paper plate of the speaker will move with it, this action changes the density of the air and produces sound. The basic principle of the moving coil loudspeaker comes from Fleming's left-hand law. Put a wire with current and the magnetic lines of force perpendicularly between the north and south poles of the magnet. The wire will move due to the interaction between the magnetic lines of force and the current. Then attach the diaphragm to this wire. As the current changes, the diaphragm will move back and forth. The broadcast loudspeaker provides people with diversified, full coverage, fast and convenient information services.

[0003] However, it still has some disadvantages. For example, since the direction of the speaker needs to be adjusted after installation, it needs to be disassembled and reinstalled in another direction. Such adjustment is very inconvenient, which reduces the applicability of the speaker. Moreover, since broadcast speakers are usually fixed in a higher position for use, they are inconvenient to clean. Long-term use will accumulate certain garbage at the speaker mouth, thereby affecting the volume and sound quality of the speaker.

[0004] In order to solve the above problems, the present application proposes a speaker that is easy to adjust its direction. Utility Model Content

[0012] Preferably, a connecting slot is provided on the inner wall of the protection frame, and a telescopic button is movably connected to the outer surface of one side of the protection inner plug.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model realizes that the direction of the speaker can be freely adjusted by setting the rotatable inner column of the rotating device in the outer column of the rotating device, and utilizing the movable buckle on the outer wall of the rotating inner column to cooperate with the rotating slot on the inner wall of the rotating outer column, so that the direction of the speaker can be changed after installation without the need to disassemble it and reinstall it, thereby improving the adjustability and practicality of the speaker.

[0015] The utility model provides a protective net in the protective device with isolation and air permeability, so that after the protective device is installed, the speaker can isolate part of the garbage and prevent birds from living there, and will not affect the propagation of its sound. The cooperation between the telescopic button and the connecting slot in the protective device makes the installation and removal of the protective device more convenient and quick, and a protective cotton pad is installed in the protective frame to effectively avoid wear between the protective device and the speaker.
