A horn with a novel sealing structure

Abstract

This utility model relates to the field of loudspeaker technology and discloses a loudspeaker with a novel sealing structure, including a housing body and a speaker body. A top mounting plate is fixed to the top of the housing body, a positioning post is fixed to the top of the top mounting plate, and a sealing ring is fixed to the outside of the positioning post. This utility model fixes the top mounting plate to the top of the housing body. When positioning the top cover plate, a sealing strip is first fixed to the gap between the locking block and the top cover plate, providing a certain sealing effect. Simultaneously, the locking plate at the bottom of the top cover plate is engaged with the limiting plate, and the positioning post is engaged inside the positioning groove to prevent the top cover plate from moving. Then, the sealing ring is fixed to the outside of the positioning post, so the sealing ring is precisely located around the positioning groove at the bottom of the top cover plate. This allows the sealing ring to seal the gaps in the positioning post and positioning groove, thereby improving the overall top sealing effect.

Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a loudspeaker with a novel sealing structure. Background Technology

[0002] A loudspeaker is a modern electroacoustic component that converts electrical signals into sound. It is a 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 diaphragm to vibrate. Because the electronic energy changes constantly, the loudspeaker coil will move forward or backward, and the loudspeaker diaphragm will move accordingly. These actions change the density of the air, thus producing sound.

[0003] In daily life, loudspeakers are a common type of device. The most crucial aspect of loudspeaker use is its sound output. If the sealing is poor, it can easily affect the sound quality and cause sound leakage. Sound can bounce, cross, and leak inside the loudspeaker, resulting in sound mixing and distortion. Utility Model Content

[0004] The purpose of this utility model is to provide a speaker with a novel sealing structure to solve the problems mentioned in the background art, which are that if the sealing effect is not good during use, it will easily affect the sound quality and cause sound leakage. The sound will bounce, cross and leak inside the speaker, which will easily cause sound mixing and destruction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a speaker with a novel sealing structure, comprising a housing body and a speaker body, a top mounting plate fixed to the top of the housing body, a limiting plate fixed to the top of the top mounting plate, a locking block fixed to one side of the top of the top mounting plate, a top cover plate disposed between the locking blocks, a sealing strip fixed to the gap between the locking blocks and the top cover plate, a positioning groove provided in the bottom of the top cover plate, a locking plate fixed to the bottom of the top cover plate, a positioning post fixed to the top of the top mounting plate, and a sealing ring fixed to the outside of the positioning post.

[0006] As a further technical solution of this utility model, the position of the positioning post corresponds one-to-one with the positioning groove, and the inner diameter of the positioning groove is larger than the outer diameter of the positioning post.

[0007] As a further technical solution of this utility model, the outer diameter of the sealing ring is larger than the inner diameter of the positioning groove, and the limiting plate is symmetrically distributed about the central axis of the positioning plate.

[0008] As a further technical solution of this utility model, a bottom plate is fixed to the top of the outer shell body, a mounting bracket bottom plate is provided below the speaker body, mounting bracket side plates are fixedly installed on both sides of the mounting bracket bottom plate, and a sealing plate is fixed to the inner wall of the outer shell body.

[0009] As a further technical solution of this utility model, a third screw groove is provided in the bottom of the mounting bracket side plate, and a second bolt is threadedly connected between the two sides of the mounting bracket bottom plate and the mounting bracket side plate through the third screw groove.

[0010] As a further technical solution of this utility model, the side plates of the mounting frame are symmetrically distributed about the central axis of the mounting frame base plate, and side wing plates are fixed to the sides of the side plates of the mounting frame.

[0011] As a further technical solution of this utility model, the top of the base plate is fixed with two locking posts on both sides, the locking posts are symmetrically distributed about the central axis of the base plate, the side wing plate is provided with a first screw groove, the top of the locking post is provided with a second screw groove, and a first bolt is connected in both the first screw groove and the second screw groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the horn with a novel sealing structure not only improves the sealing assembly capability, but also improves the horn's positioning and assembly capabilities.

[0013] (1) By fixing the top mounting plate to the top position of the outer shell body and fixing the locking block to the top position of the top mounting plate, the locking plate is fixed to the bottom of the top cover plate. When equipping the top cover plate, a sealing strip is first fixed in the gap between the locking block and the top cover plate. The sealing strip has a certain sealing effect. At the same time, the locking plate at the bottom of the top cover plate will be locked between the limiting plates, and the positioning post will be locked inside the positioning groove to prevent the top cover plate from moving. Then the sealing ring is fixed outside the positioning post. Therefore, the sealing ring is located around the positioning groove at the bottom of the top cover plate. In this way, the sealing ring can be used to seal the gap when the positioning post and positioning groove are positioned, thereby improving the overall top sealing effect.

[0014] (2) By fixing the locking posts on both sides of the top of the base plate and fixing the side wing plate on the side of the mounting bracket, when assembling the speaker body, since the speaker body is first loaded between the mounting bracket base plate and the mounting bracket side plate, the side wing plate will fall exactly above the locking posts and be locked, thereby improving the overall locking capability.

[0015] (3) By opening a third screw groove in the bottom of the mounting bracket side plate, the second bolt can be used to lock the position when assembling the mounting bracket base plate and mounting bracket side plate. The second screw groove is opened in the top of the positioning post, and the first screw groove is opened in the side wing plate. Therefore, after the side wing plate is just above the positioning post, the first screw groove and the second screw groove are aligned with each other, and then the first bolt is used to lock the position. Therefore, the overall assembly capability is improved in the working process. Attached Figure Description
