Description

Technical Field

[0001] This invention relates to the field of audio equipment technology, and more specifically to a speaker module and speaker enclosure. Background Technology

[0002] Entertainment venues often offer live performances by bands or singers, enhanced by high-end sound equipment to improve the atmosphere and entertainment experience. However, traditional sound equipment has a fixed position and angle. A stereo rotating sound system (application number 201911167531.9) includes a central rotating section, main beam, moving beam, push-pull section, speaker housing, reciprocating trigger mechanism, speaker base, subwoofer, and disengagement mechanism. By utilizing the multi-degree-of-freedom changes of the speaker housing and the alternating engagement and disengagement of the subwoofer, it can create variations in sound distance, repeated emphasis and reduction, repeated subwoofer activation and deactivation, and add special effects and fun, thus improving the entertainment experience. However, the position of this device is not easily adjustable, thus affecting the overall usability of the sound system. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a speaker module and a speaker box, which has the advantage of being able to easily change the position of the speaker, thereby outputting sound effects in different directions.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A loudspeaker module includes a housing, a diaphragm mounted on the housing, and a mesh fabric fixed to the front side of the housing to wrap the diaphragm. Two sliding sleeves are symmetrically fixed to the housing. An arc-shaped frame is slidably connected inside the lower sliding sleeve, and an arc-shaped rack is slidably connected inside the upper sliding sleeve. Two side frames are symmetrically fixed between the arc-shaped frame and the arc-shaped rack.

[0006] Motor II is fixedly connected to the upper sliding sleeve, and a gear is fixedly connected to the output shaft of motor II. The gear meshes with the arc-shaped rack for transmission.

[0007] A slot is provided on the back of the housing.

[0008] The shell is arranged symmetrically in two parts.

[0009] A crossbeam is fixedly connected in the middle between the arc-shaped frame and the arc-shaped rack, and two inner clamping plates are symmetrically and movably connected on the crossbeam.

[0010] Each of the two side frames is equipped with a slide, and an outer clamp is fixed to the inner side of each slide. Each of the two slides is also fixed with a first electric push rod, and the telescopic ends of the two first electric push rods are respectively fixed to the two side frames.

[0011] A speaker includes a mounting frame, on which a speaker module is fixedly connected by screws. Screw holes are provided on two sides of the speaker module for inserting screws to fix the side frame to the mounting frame, thereby realizing the installation of the speaker.

Detailed Implementation

[0025] like Figures 3 to 4As shown:

[0026] A loudspeaker module includes a housing 201, a diaphragm 203 mounted on the housing 201, and a mesh fabric 202 fixed to the front side of the housing 201 to wrap the diaphragm 203. Two sliding sleeves 205 are symmetrically fixed on the housing 201. An arc-shaped frame 102 is slidably connected in the lower sliding sleeve 205, and an arc-shaped rack 103 is slidably connected in the upper sliding sleeve 205. Two side frames 101 are symmetrically fixed between the arc-shaped frame 102 and the arc-shaped rack 103.

[0027] The sliding sleeve 205 on the housing 201 can slide on the arc frame 102, thereby easily changing the position of the housing 201, which in turn changes the orientation of the diaphragm 203, and outputs sound effects in different directions. During use, the housing 201 can slide back and forth on the arc frame 102 to create a gradually approaching and receding effect, thus improving the entertainment effect of the audio system.

[0028] like Figure 5 As shown:

[0029] A motor II 207 is fixedly connected to the upper sliding sleeve 205. A gear 206 is fixedly connected to the output shaft of the motor II 207. The gear 206 meshes with the arc-shaped rack 103 for transmission.

[0030] When motor II 207 starts, it drives gear 206 to rotate. Gear 206 drives sliding sleeve 205 to slide on arc rack 103 through meshing transmission. Sliding sleeve 205 drives housing 201 to slide along the path of arc frame 102, thereby changing the position of housing 201.

[0031] like Figure 5 As shown:

[0032] The back of the housing 201 is provided with a slot 204; the slot 204 is used to pass through the terminal block for convenient electrical connection with the diaphragm 203.

[0033] like Figures 1 to 2 As shown:

[0034] Two housings 201 are symmetrically arranged; the two housings 201 can be moved to the positions on both sides respectively, and output sound effects to both sides at the same time, thereby increasing the range covered by the sound effects. Alternatively, the two housings 201 can be moved to the same side, so that the two housings 201 combined together can enhance the sound effect output.

[0035] like Figures 6 to 7 As shown:

[0036] A crossbeam 104 is fixedly connected in the middle between the arc-shaped frame 102 and the arc-shaped rack 103, and two extendable inner clamping plates 303 are symmetrically installed on the crossbeam 104.

[0037] During installation, when the speaker module needs to be installed on two pillars, the two inner clamping plates 303 are controlled to move away from each other, so that the two inner clamping plates 303 are pressed tightly against the opposite surfaces of the two adjacent pillars, thereby achieving a certain fixing effect on the device.

[0038] like Figure 8 As shown:

[0039] Each of the two side frames 101 is fitted with a slide 401, and an outer clamp 402 is fixedly connected to the inner side of each of the two slides 401. Each of the two slides 401 is fixedly connected with a first electric push rod, and the telescopic ends of the two first electric push rods are respectively fixedly connected to the two side frames 101.

[0040] The columns on both sides are located between the outer clamping plate 402 and the inner clamping plate 303 on the corresponding sides. The two first electric push rods are activated to drive the two slides 401 to move closer to each other. The two slides 401 drive the two outer clamping plates 402 to move closer to each other. The two outer clamping plates 402 are clamped on the outer surfaces of the two columns, thereby further increasing the fixing effect of the device from the outside. The two inner clamping plates 303 are pressed tightly against the two columns from the inside, and together with the two outer clamping plates 402, they are pressed tightly against the two columns from the outside, thereby realizing the installation and fixing of the two housings 201 between the two columns.

[0041] Secondly, since the two outer clamping plates 402 can move independently and the distance that the two inner clamping plates 303 move outward can also be adjusted, the distance between the inner clamping plates 303 and the outer clamping plates 402 on the same side can be adjusted, so that they can be clamped and fixed on columns of different diameters, and can be installed between two columns with different spacing.

[0042] Furthermore, the inner clamping plate 303 and the outer clamping plate 402 are attached and clamped to the column from both sides, rather than being sleeved onto the column along the column axis. Therefore, the device can be freely installed directly at the designated position on the column without having to insert it from above or below the column and then adjust the height of the device.

[0043] like Figures 6 to 7 As shown:

[0044] Two symmetrical sliding grooves 105 are opened on the crossbeam 104. A hinge seat 301 is slidably connected in both sliding grooves 105. A hinge rod 302 is hinged to both ends of the two hinge seats 301. The four hinge rods 302 are respectively connected to the two ends of the two inner clamping plates 303. A motor I 106 is fixed in both sliding grooves 105. A screw 107 is connected to the output shaft of the two motors I 106 through a coupling. The two hinge seats 301 are respectively threaded to the two screws 107.

[0045] The two slides 105 start to drive the two motors I 106 to rotate. The two motors I 106 drive the two hinge seats 301 to move closer to each other or away from each other. The two hinge seats 301 slide in the two slides 105, and then drive the two inner clamping plates 303 to move away from each other or closer to each other through the hinge rods 302 on them. This allows the two inner clamping plates 303 to fit against the two adjacent columns, and at the same time, the device is positioned in the middle of the two columns, thus making the installation of the device more stable.

[0046] like Figures 9 to 11 As shown:

[0047] Each of the two side frames 101 is fitted with a wheel frame 403, and each of the two wheel frames 403 is fixedly connected to a motor IV 404. Each of the two motor IV 404 is fixedly connected to an outer rubber wheel 405. Each of the two side frames 101 is fixedly connected to a second electric push rod, and the telescopic ends of the two second electric push rods are respectively fixedly connected to the two side frames 101. Each of the two outer clamping plates 402 is provided with a slot through which the outer rubber wheel 405 can pass.

[0048] Motor III 304 is fixedly connected to both inner clamping plates 303, and inner rubber wheel 305 is fixedly connected to both motor III 304. Square grooves for passing through the inner rubber wheel 305 are provided on both inner clamping plates 303.

[0049] When the two inner clamping plates 303 are attached to the inner side of the column, the two inner rubber wheels 305 are also simultaneously attached to the inner side of the column. Controlling the two second electric push rods activates the two wheel frames 403, causing them to move closer together. The two wheel frames 403 drive the two outer rubber wheels 405 to move inwards, passing through the slots on the two outer clamping plates 402 and attaching to the column. At this time, controlling the two first electric push rods activates the two outer clamping plates 402, causing them to slide away from the column and separate. Controlling the two motors IV 404 and two motors III 304 activates them, causing the two inner rubber wheels 305 and the two outer rubber wheels 405 to rotate synchronously, thus moving the outer... With the combined action of rubber wheel 405 and inner rubber wheel 305, the device moves up and down along the axis of the column under the action of friction. This allows the vertical height of the two housings 201 relative to the column to be easily changed without the need for workers to reinstall and adjust. This allows the two housings 201 to output sound effects from different heights. After adjusting the height of the bowl, the two outer clamps 402 are once again attached to the column, achieving stable fixation of the device. During this process, since the two inner clamps 303 are attached to the two columns respectively, they can guide the upward movement of the device, allowing it to move steadily up and down.

[0050] A speaker includes a mounting frame on which a speaker module is fixedly attached by screws. Two side frames 101 on the speaker module are provided with screw holes for inserting screws to fix the side frames 101 to the mounting frame, thereby realizing the installation of the speaker.
