Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a directional ceiling-mounted square loudspeaker. Background Art

[0002] Loudspeakers, also called speakers or speakers, are a very commonly used electroacoustic transducer. With the improvement of the quality of life, people's demand for aesthetics has also increased, especially in the field of building decoration. In order to make the interior clean and beautiful, most of the light-emitting or sound-emitting devices will be installed in a ceiling-mounted embedded structure, such as embedded in the wall or embedded in the ceiling. Therefore, ceiling speakers are also widely used.

[0003] The publication number is: CN206365019U. The utility model discloses a ceiling-mounted speaker, including an integrated basin frame, wherein the integrated basin frame is provided with a magnetic circuit system, the magnetic circuit system is directly embedded in the integrated basin frame by injection molding, a transformer is installed inside the integrated basin frame, a mesh cover is provided on the top of the integrated basin frame, a wire hole is also provided inside the integrated basin frame, and a speaker line is provided inside the wire hole. The ceiling-mounted speaker integrates the speaker basin frame with the outer shell to form an integrated basin frame, thereby achieving lightness, eliminating unnecessary resonance, improving sound quality, optimizing the production process, and increasing the product qualification rate; a spiral wire hole is designed on the back to hide excessively long wiring, eliminate the possibility of touching the speaker vibration system, and at the same time achieve integration with on-site wiring to eliminate unnecessary hidden dangers.

[0004] The above description introduces the loudspeaker and the rising sound, but the existing loudspeaker has the following technical problems:

[0005] 1. When some existing speakers are installed on the ceiling or wall, the sound propagation direction of the ceiling speaker is always perpendicular to the ceiling or wall. In this case, the ceiling speaker needs to be installed in a position facing the gathering of users to provide users with good sound effects. However, in most cases, when users gather and disperse or the ceiling or wall facing the gathering place of users cannot be installed, the overall sound effect of the ceiling speaker will be affected, and the user experience will be poor.

[0006] The existing speakers are complicated and cumbersome in the installation and removal process, and certain requirements are imposed on the ceiling or wall before installation, and certain damage is caused to the ceiling or wall. Utility Model Content

[0007] The utility model aims to solve the technical problems of complicated loudspeaker installation process and single sound source propagation direction in the prior art, and proposes a directional ceiling-mounted square loudspeaker.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a directional ceiling-mounted square loudspeaker, comprising a box body and a box cover, characterized in that: the internal array of the box body is provided with a fixing rod, a motor is fixedly connected to one side of the box body, a movably connected power rod is provided at the power output end of the motor, a turntable is fixedly connected to one end of the power rod, a disc buckle is provided on the surface of one side of the turntable, a movable slide rail is provided on the surface of the turntable, and the disc buckle is located in a movable groove in the movable slide rail, a connecting plate is provided at the bottom end of the movable slide rail, a positioning rod is installed on one side of the connecting plate, a speaker body is provided at the bottom end of the connecting plate, limit plates are provided on both sides of the speaker body, a fixing plate is mirrored on the top of the box body, a suction cup is provided between the two fixing plates, and a connecting rod is provided in an array on one side of the box cover.

[0009] It can be seen that in the above technical solution, when the position of the sound source needs to be adjusted, the motor is started, and the motor outputs power to the power rod. The power rod rotates to drive the turntable to rotate. When the turntable rotates, the disc buckle on the turntable rotates with the turntable, and the connecting plate moves along with the disc buckle through the moving slide rail. Since the connection method between the positioning rod and the connecting rod is a rotating joint, the eccentric shaft principle is used to make the speaker body at the bottom of the connecting plate swing horizontally left and right, thereby realizing the change of the propagation direction of the sound source.

[0010] Preferably, the hole at one end of the fixing rod is interlocked with the connecting rod 3, and the positions of the fixing rod and the connecting rod correspond to each other.

[0011] It can be seen that in the above technical solution, the fixing rod and the connecting rod cooperate with each other to fix the box cover so that it will not fall off.

[0012] Preferably, the tray at the bottom end of the suction cup is welded to the box body, and the suction cup is parallel to the top end of the fixing plate.

[0013] It can be seen that in the above technical solution, during installation, the screws can be stably installed after the suction cup is adsorbed, and there is no need to worry about the speaker falling off the ceiling or wall.

[0014] Preferably, the distance between two adjacent limiting plates is the same as the size of the speaker body, and the two limiting plates are respectively fixedly connected to the box cover and the bottom of the box body.

[0015] It can be seen that in the above technical solution, when the speaker body swings left and right, the limit plate can make its direction at the horizontal coordinate, and the swing direction of the speaker body is offset.

[0016] Preferably, the positioning rod is fixedly connected to the box body, and the connection between the positioning rod and the connecting plate is a rotating joint structure.

[0017] It can be seen that in the above technical solution, the fixing rod is the shaft that fixes the position of the connecting plate, and the rotating joint structure enables the connection between the positioning rod and the connecting plate to only rotate in situ, thereby realizing the principle of the eccentric shaft structure.

[0018] Preferably, the buckle is the same size as the movable slide rail, and the top surface of the buckle protrudes from the movable slide rail.

[0019] It can be seen that in the above technical solution, the protruding portion can prevent the disc buckle from being separated from the moving slide rail due to external force or other factors when moving in the moving slide rail.

[0020] Preferably, the box cover and the front opening of the box body cooperate with each other, and the box cover and the back of the box body have the same shape.

[0021] It can be seen that in the above technical solution, a chimeric structure is used. When the interior of the speaker needs to be opened, it is only necessary to pry open the gap at the connection between the box cover and the box body to separate the fixing rod from the connecting rod to open the box cover.

[0022] Beneficial Effects

[0023] In the utility model, an eccentric shaft movable structure is adopted, and the direction of the sound source can be adjusted according to the use requirements. The output end of the motor drives the power rod to rotate the turntable, and the disc buckle on the turntable moves in the movable slide rail, and the disc buckle drives the connecting plate to swing horizontally. The positioning rod is movably connected to the connecting plate and fixedly connected to the box body. The connecting plate swings, which causes the positioning rod to rotate in situ, thereby moving the position of the speaker body left and right. After the sound position of the speaker body meets the use requirements, the motor stops outputting power, the turntable stops rotating, and the position of the speaker will be fixed. It can cope with various usage scenarios and allow users to have good sound effects.

[0024] In the utility model, during the installation process, the position of the speaker device can be first located by using a suction cup. After the suction cup is sucked to the ceiling or wall, screws are used to enter from the holes on the bottom surface of the fixing plate. After the screws connect and fix the fixing plate to the ceiling or wall, the installation can be completed. When disassembly is required, only the screws need to be unscrewed and the suction cup can be controlled to stop working to complete the disassembly of the speaker. The overall process is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
