Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker sealing, in particular to a high-sealing structure of a dust cap of a loudspeaker. Background Art

[0002] The loudspeaker is divided into several different musical instruments. One is a wind instrument, which is thin at the top and thick at the bottom and is mostly made of copper. The other is a modern electro-acoustic component, which is used to convert electrical signals into sounds and is also called a loudspeaker.

[0003] When the existing loudspeaker is in normal use, it usually only uses a single dust cover, dust cap and other structures for dust prevention measures to prevent foreign objects from entering the inside of the loudspeaker. The protective effect of this single dust prevention measure is inevitably insufficient during the long-term use of the loudspeaker, which may lead to foreign objects entering the inside of the loudspeaker. For this reason, a high-sealing structure of a dust cap of a loudspeaker is proposed here in this application. Summary of the Invention

[0004] The purpose of the utility model is to provide a high-sealing structure of a dust cap of a loudspeaker, so as to solve the problem that the technical solution provided in the above background art provides double sealing measures and effectively reduces the risk of foreign objects entering the inside of the loudspeaker.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-sealing structure of a dust cap of a loudspeaker, including a U-shaped iron, a magnet is installed near the top inside the U-shaped iron, and a cover plate is installed on the top of the U-shaped iron. A washer is installed inside the cover plate, and a chassis is installed on the top of the cover plate. Terminals are installed on the bottom of the chassis. A diaphragm is installed inside the chassis. A dust cap is arranged on the top of the diaphragm, and a bead is jointly arranged on the top of the diaphragm and the dust cap. The bead is installed on the top of the dust cap. A brocade silk thread is installed on the bottom of the diaphragm, and a voice coil is also installed on the diaphragm. A spider is installed outside the voice coil. An aluminum ring is embedded inside the U-shaped iron. The aluminum ring is located at the bottom of the magnet, and a gasket is installed inside the aluminum ring. A wire mesh is embedded between the bottom of the gasket and the inner wall of the U-shaped iron.

[0006] Preferably, the dust cap is arc-shaped, and the arc surface of the dust cap faces upward.

[0007] Preferably, an installation groove is opened on the bottom of the inner wall of the U-shaped iron, and the wire mesh is embedded inside the installation groove.

[0008] Preferably, the inner diameter of the aluminum ring is the same as the outer diameter of the gasket.

[0009] Preferably, the terminals are located near the right side of the bottom of the chassis.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By providing a dust cap and an iron net, the dust net can initially perform dust prevention and protection operations on the whole. At the same time, the setting of the iron net can further prevent foreign objects from entering the interior and improve the overall safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1 , the present utility model provides a technical solution: a high-sealing structure of a dust cap of a speaker, including a U-shaped iron 6. A magnet 5 is installed near the top inside the U-shaped iron 6, and a cover plate 11 is installed on the top of the U-shaped iron 6. A washer 4 is installed inside the cover plate 11, and a speaker frame 8 is installed on the top of the cover plate 11. A terminal 10 is installed on the bottom of the speaker frame 8, and the terminal 10 is located near the right side of the bottom of the speaker frame 8. A diaphragm paper 2 is installed inside the speaker frame 8. A dust cap 1 is provided on the top of the diaphragm paper 2, and a crimping edge 12 is jointly provided on the top of the diaphragm paper 2 and the dust cap 1. The crimping edge 12 is installed on the top of the dust cap 1. A brocade silk thread 3 is installed on the bottom of the diaphragm paper 2, and a voice coil 7 is also installed on the diaphragm paper 2. A surround 9 is installed outside the voice coil 7. An aluminum ring 13 is embedded and installed inside the U-shaped iron 6. The aluminum ring 13 is located at the bottom of the magnet 5, and a gasket 15 is installed inside the aluminum ring 13. An iron net 14 is embedded and installed between the bottom of the gasket 15 and the inner wall of the U-shaped iron 6.

[0016] Please refer to Figure 1 , the dust cap 1 is arranged in an arc shape, and the arc surface of the dust cap 1 faces upward. Through this setting, the sundries isolated by the dust cap 1 can slide along the arc surface of the dust cap 1 to the edge, which is convenient for subsequent cleaning.

[0017] Please refer to Figure 1 , an installation groove is opened on the bottom of the inner wall of the U-shaped iron 6, and the iron net 14 is embedded in the inner cavity of the installation groove. Through this setting, it is convenient to install the iron net 14, and the installation position of the iron net 14 is fixed, which can achieve a better isolation effect.
