Description

Technical Field

[0001] The utility model relates to the technical field of micro speakers, and more specifically, the utility model relates to a cavity of a micro speaker. Background Art

[0002] A speaker refers to a device that can convert an audio signal into sound. Generally speaking, it means that a power amplifier is built into the main body of the speaker or the subwoofer box, and after the audio signal is amplified, the speaker itself plays back the sound to make the sound louder.

[0003] Existing speakers generally consist of a box body, a speaker, and a frequency divider. The speaker converts the electrical signal output by the power amplifier into a sound signal and then radiates it out. The box body is used to eliminate the acoustic short circuit of the speaker unit, suppress its acoustic resonance, broaden its frequency response range, and reduce distortion. The frequency divider has functions such as frequency band division, amplitude-frequency characteristic and phase-frequency characteristic correction, impedance compensation and attenuation. However, most traditional speakers are designed with a large volume and are usually suitable for use in specific occasions. When used indoors at home, for the decoration style, large-volume speakers will cause a certain visual impact and adverse invisibility. Therefore, the prior art uses a micro speaker that can meet the needs of most families.

[0004] However, in actual use, due to the small size of the micro speaker, the size of the matching fixing screws is also small. When disassembling and maintaining the speaker, after removing the screws, the entire speaker needs to be flipped over to pour out the screws. And because the screws will bounce up and then fall when they drop, it is difficult to observe the exact position of the screws, which causes inconvenience for subsequent installation of the speaker. Summary of the Utility Model

[0005] The cavity of a micro speaker provided by the utility model aims to solve the following problem: The existing micro speaker has a small size, and the size of the matching fixing screws is also small. When disassembling and maintaining the speaker, after removing the screws, the entire speaker needs to be flipped over to pour out the screws. And because the screws will bounce up and then fall when they drop, it is difficult to observe the exact position of the screws, which causes inconvenience for subsequent installation of the speaker.

[0006] To achieve the above object, the present utility model provides the following technical solution: A micro speaker cavity, including a housing and a mounting base, the mounting base is fixedly installed on one side of the housing, a top cover is provided on the top of the housing, a base is provided on the bottom of the housing, a front housing is provided inside the housing, a rear housing is provided on one side of the front housing, connecting pipes are symmetrically provided on both the front housing and the rear housing, a screw is provided between the two connecting pipes, and the screw is used to fix the front housing and the rear housing to each other; a connecting component is provided between the screw and the connecting pipe on the rear housing, the connecting component includes a fixing ring, the fixing ring is slidably connected to the connecting pipe, a movable ring is rotatably provided inside the fixing ring, the screw is installed inside the movable ring, the screw is rotatably connected inside the fixing ring through the movable ring, and is slidably connected inside the connecting pipe through the fixing ring.

[0007] In a preferred embodiment, the connecting component further includes a spring, the spring is used to pull the fixing ring to slide inside the connecting pipe, the spring is provided outside the fixing ring, the number of springs is set to be multiple, and the springs are fixedly connected to the inner wall of the connecting pipe.

Detailed implementation manners

[0020] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0021] Referring to the attached drawings of the specification Figure 1 - Figure 5 A micro speaker cavity includes an outer shell 1 and a mounting seat 2. The mounting seat 2 is fixedly installed on one side of the outer shell 1. A top cover 3 is provided at the top of the outer shell 1, and a base 4 is provided at the bottom of the outer shell 1. A front housing 5 is provided inside the outer shell 1. A rear housing 6 is provided on one side of the front housing 5. Connecting pipes 7 are symmetrically provided on both the front housing 5 and the rear housing 6. A screw 8 is provided between the two connecting pipes 7. The screw 8 is used to fix the front housing 5 and the rear housing 6 to each other. A connecting component 9 is provided between the screw 8 and the connecting pipe 7 on the rear housing 6. The connecting component 9 includes a fixed ring 901. The fixed ring 901 is slidably connected to the connecting pipe 7. An inner movable ring 902 is rotatably provided inside the fixed ring 901. The screw 8 is installed inside the movable ring 902. The screw 8 is rotatably connected inside the fixed ring 901 through the movable ring 902 and is slidably connected inside the connecting pipe 7 through the fixed ring 901.

[0022] It should be noted that since the screw and the movable ring are fixedly connected through a limiting ring, when the screw is subjected to the pulling force of the spring, the screw will not fall off.

[0023] Through the above technical solution, as shown in Figure 5 the screw 8 moves inside the connecting pipe 7 through the fixed ring 901. The fixed ring 901 can limit the screw 8, and there is no need to place the screw 8 separately.

[0024] Further, the connecting component 9 further includes a spring 903. The spring 903 is used to pull the fixing ring 901 to slide inside the connecting pipe 7. The spring 903 is arranged outside the fixing ring 901, and the number of the springs 903 is set to be multiple. The spring 903 is fixedly connected to the inner wall of the connecting pipe 7.

[0025] It should be noted that the spring 903 is connected to the inner wall of the outer end of the connecting pipe 7. When the fixing ring 901 drives and slides inside the connecting pipe 7, the spring 903 will stretch as the fixing ring 901 moves, and will generate a reverse pulling force on the fixing ring 901.

[0026] Further, a plurality of sliders 904 are arranged on the outer side of the fixing ring 901, and sliding grooves 905 corresponding to the sliders 904 one by one are arranged on the inner wall of the connecting pipe 7.

[0027] It should be noted that the fixing ring 901 drives the slider 904 to slide inside the slider 904, which can limit the fixing ring 901 and enable the fixing ring 901 to move horizontally along the connecting pipe 7.

[0028] Further, two grooves are respectively arranged on the inner wall of the fixing ring 901 and the side surface of the movable ring 902, and a plurality of sliding beads 906 are jointly arranged inside the two grooves.

[0029] It should be noted that when the movable ring 902 rotates inside the fixing ring 901, it drives the sliding beads 906 to slide inside the grooves between the movable ring 902 and the fixing ring 901, which can limit the position between the movable ring 902 and the fixing ring 901 and limit the movable ring 902 inside the fixing ring 901.

[0030] Further, referring to the attached drawings of the specification Figure 2 , reinforcing ribs 10 are arranged on the inner walls of the front shell 5 and the rear shell 6, and the number of the reinforcing ribs 10 is set to be multiple.

[0031] It should be noted that the reinforcing ribs 10 can increase the hardness of the front shell 5 and the rear shell 6, prevent the front shell 5 and the rear shell 6 from deforming, and can increase the service life of the front shell 5 and the rear shell 6.

[0032] Working principle: When disassembling the front housing 5 and the rear housing 6, first open the top cover 3 and the base 4, separate the outer shell 1 from the front housing 5 and the rear housing 6, expose the front housing 5 and the rear housing 6, and then rotate the screw 8 inside the connecting pipe 7. Since the screw 8 is fixedly connected to the movable ring 902 through the limiting ring, during the process of rotating the screw 8, the movable ring 902 will be driven to rotate inside the fixed ring 901, so that the sliding beads 906 between the movable ring 902 and the fixed ring 901 slide inside the groove, which can not only limit the movable ring 902 and the fixed ring 901, but also reduce the resistance of the movable ring 902 rotating inside the fixed ring 901, preventing the screw 8 from jamming during rotation, and the screw 8 can be separated from the connecting pipe 7 on the front housing 5, realizing the disassembly of the front housing 5 and the rear housing 6;

[0033] Then, through the elasticity of the spring 903, a reverse pulling force is applied to the fixed ring 901, pulling the screw 8 from one end close to the connecting pipe 7 on the front housing 5 to one end far from the connecting pipe 7 on the front housing 5. And when the fixed ring 901 slides inside the connecting pipe 7, it drives the outer slider 904 to slide inside the chute 905. The slider 904 can limit the fixed ring 901 inside the chute 905, preventing the fixed ring 901 from falling off inside the connecting pipe 7;

[0034] Through the above steps, conversely, the screw 8 can be moved along the inside of the connecting pipe 7 on the rear housing 6 and connected to the connecting pipe 7 on the front housing 5, realizing the installation of the front housing 5 and the rear housing 6.

[0035] After separating the screw 8 from the connecting pipe 7 on the front housing 5, the disassembly and maintenance of the front housing 5 and the rear housing 6 can be realized. And after disassembly, the screw 8 can still be fixed inside the movable ring 902, so that the screw 8 does not need to be placed separately, nor does it need to be poured out from the inside of the rear housing 6, thus preventing the loss of the screw 8 and realizing the quick installation of the front housing 5 and the rear housing 6 through the screw 8.

[0036] The utility model cooperates the fixed ring 901 and the movable ring 902 with the spring 903, which can not only fix the screw 8, but also quickly move the screw 8 to one end of the opening on the connecting pipe 7, exposing the screw 8 for convenient operation of the screw 8.

[0037] The above embodiments only represent several implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
