Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a speaker with waterproof measures. Background Technique

[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in audio equipment, but for the audio effect, it is the most important component. There are many types of speakers, and the prices vary greatly. The audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects and resonate (sympathize) with the surrounding air to emit sound.

[0003] Chinese Patent (authorized announcement number: CN 207166754 U) proposes a speaker structure. The patent includes a speaker body, a magnetic conductive plate and a mounting end. An anti-magnetic cover is sleeved outside the speaker body, and a T-iron is arranged inside the speaker body. An installation plate is arranged at the lower end of the anti-magnetic cover, and a shock-absorbing sheet is arranged between the anti-magnetic cover and the installation plate. An upper clamping plate is arranged at the upper end of the anti-magnetic cover, and installation bolts are arranged at the edge of the installation plate. The structure of the utility model is scientific and reasonable, safe and convenient to use. The design optimizes the structure of the speaker, reduces the radius of the paper cone. After the paper cone is installed, the original glue used to bond the paper cone overflows along the edge of the paper cone to fix the pressing ring, reducing the gluing process and the labor intensity of the staff. A shock-absorbing sheet is arranged to reduce the vibration between the speaker and the contact surface. The design is not only simple in structure, but also reduces the manufacturing process while ensuring the sound quality of the speaker and saves resources.

[0004] Speakers often work in the open air and are easily wetted by rain, resulting in damage to the speakers. The above comparative patent does not provide a waterproof structure for the speakers. Once water enters the speakers, it will damage their interiors, and the sediment in the rain is easy to enter the speakers, affecting the normal use of the speakers. To increase the waterproof and dustproof performance of the speakers, we propose a speaker with waterproof measures. Content of the Utility Model
