Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker for a projector. Background Art

[0002] Speakers are commonly known as "horns". They are a very common electroacoustic transducer device, which can be found in electronic and electrical equipment that makes sound. Speakers are transducers that convert electrical signals into sound signals. The performance of speakers has a great impact on the sound quality. Speakers are the weakest device in audio equipment, but they are also the most important component for sound effects.

[0003] Most of the existing projector speakers are fixedly installed on objects such as walls. When the speakers need to be repaired or replaced after long-term use, it is inconvenient to disassemble and reinstall them. They can only be disassembled and reinstalled as a whole, which is time-consuming and laborious. Therefore, there is an urgent need for a projector speaker to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a speaker for a projector in order to solve the problems that the existing speaker for a projector is inconvenient to disassemble and assemble, and the repair and replacement are time-consuming and laborious, etc. due to the fixed installation mode adopted.

[0006] Furthermore, the adjustment mechanism includes a fixed plate, a rotating shaft is provided between the fixed plates, one end of the rotating shaft is directly connected to a driving motor, a connecting rod is sleeved on the rotating shaft, a connecting column is fixed on one side of an outer wall of the connecting rod, a sliding groove is opened above the connecting rod, a buckle is slidably connected in the sliding groove, and a compression spring is connected between the buckle and the inner wall of the sliding groove.

[0007] Furthermore, the limiting structure includes an articulated seat, which is fixedly arranged on the outside of the limiting sleeve. A limiting sleeve is hingedly arranged on the articulated seat, and the limiting sleeve cooperates with the buckle.

[0008] Furthermore, an external thread is provided on the outside of the connecting column, and an internal thread is provided on the inside of the limiting sleeve. The external thread and the internal thread are engaged with each other, and the limiting sleeve and the connecting column are fixed by rotating the external thread and the internal thread.

[0009] Furthermore, the speaker body is connected to the projector, and the shell of the speaker body is made of a light metal material.

[0010] Beneficial effects: 1. By setting up an adjustment mechanism, the driving motor drives the shaft to rotate, thereby driving the connecting rod to rotate, and the rotation of the connecting rod drives the speaker body to rotate, thereby achieving adjustment of the angle of the speaker body.

[0011] 2. By setting the limit structure and the buckle to cooperate with each other, when the limit sleeve and the connecting column are rotated and fixed through the external thread and the internal thread, the connection between the two can be fixed to prevent the two from falling off and enhance stability. When disassembling, you only need to remove the limit sleeve from the buckle, and rotate the limit sleeve in the opposite direction to disassemble the speaker body, which is convenient and quick.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Combination Figure 1-Figure 4A speaker for a projector is shown, comprising a mounting plate 1, which is fixed to the wall by screws 2. An adjusting mechanism 3 is provided on one side of the mounting plate 1, a connecting column 4 is fixedly provided on one side of the adjusting mechanism 3, a limiting sleeve 5 is sleeved on the outside of the connecting column 4, a limiting structure 6 is fixedly provided on the outside of the limiting sleeve 5, a speaker body 7 is fixedly connected to one side of the limiting sleeve 5, the speaker body 7 is connected to the projector, and the outer shell of the speaker body 7 is made of a lightweight metal material. The lighter metal material can make the speaker body 7 lighter and more labor-saving during disassembly and installation.

[0021] The adjustment mechanism 3 includes a fixed plate 31, a rotating shaft 32 is provided between the fixed plates 31, one end of the rotating shaft 32 is directly connected to a driving motor 33, a connecting rod 34 is sleeved on the rotating shaft 32, a connecting column 4 is fixedly arranged on one side of the outer wall of the connecting rod 34, a sliding groove 35 is provided above the connecting rod 34, a buckle 36 is slidably connected in the sliding groove 35, and a compression spring 37 is connected between the buckle 36 and the inner wall of the sliding groove 35. The limiting structure 6 includes an articulated seat 61, the articulated seat 61 is fixedly arranged outside the limiting sleeve 5, a limiting clamping sleeve 62 is hingedly provided on the articulated seat 61, and the limiting clamping sleeve 62 cooperates with the buckle 36. An external thread 8 is provided on the outside of the connecting column 4, and an internal thread 9 is provided inside the limiting sleeve 5. The external thread 8 and the internal thread 9 are engaged with each other, and the limiting sleeve 5 and the connecting column 4 are fixed by rotating and engaging the external thread 8 with the internal thread 9.
