An electroacoustic transducer with waterproof effect

Abstract

The electroacoustic transducer with the waterproof effect comprises a first shell, a vibrating diaphragm and a second shell, sound holes are formed in the left side and the right side of the first shell, vertical supports are fixedly installed at the top ends of the periphery of the first shell, and a fixing clamping plate is fixedly installed at the top end of the middle section of the first shell. The invention discloses an electroacoustic transducer with a waterproof effect. The design of the sound holes can help to improve the sound transmission effect of the converter; meanwhile, due to the design of the second shell, on one hand, redundant water vapor can slide down from the top end; water is prevented from entering the converter; waterproof effect is increased. Meanwhile, water vapor can be prevented from entering the converter along a connecting gap, the practicability of the electroacoustic converter is further improved, the disassembly convenience of the second shell can be improved through the design of the vertical support, and the design of the interior of the second shell can circularly amplify vibration sound waves, so that the practicability of the electroacoustic converter is improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic transducers, in particular to an electroacoustic transducer with waterproof effect. Background technique [0002] Generalized electroacoustic applications have a wide frequency range, including infrasound, audible sound, and ultrasonic transducers. Electroacoustic transducers in the frequency range of audible sound include microphones, loudspeakers, receivers, hearing aids, etc. Inside the transducer, the electrical system and the mechanical vibration system are connected to each other through certain physical effects to complete energy. Externally, the electrical system of the transducer matches the output circuit of the signal generator, or the input circuit of the preamplifier; and the mechanical vibration system of the transducer matches the sound field with its vibration surface. [0003] However, because the existing electro-acoustic transducers require sound transmission, most of t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an electro-acoustic transducer with waterproof effect, to solve the above-mentioned background technology, because the existing electro-acoustic transducer requires sound transmission, so most of its interior is open design, which is easy to affect the internal parts The normal use effect, and the general electro-acoustic converters are integrated connection, can not be disassembled, timely cleaning of the internal accessories, to achieve waterproof and improve the service life of the problem
