Diaphragm, speaker

Abstract

The present invention provides a vibrating membrane, including a vibrating membrane main body. The vibrating membrane main body includes an outer fixing part, a ring part protruding from the inner ring side of the fixing part and capable of producing elastic deformation, and an inner ring located at the ring part. On the inner part of the test, the main body of the diaphragm is made of waterproof and breathable material with waterproof and breathable micro-holes. The invention also provides a loudspeaker with the diaphragm. The technical scheme of the present invention makes the main body of the diaphragm by using a waterproof and breathable material with waterproof and breathable micropores, so that the main body of the diaphragm has micropores, and the size of the micropores is between the water molecules and the air molecules, so that the air molecules can pass through smoothly. , while effectively blocking the passage of water molecules, so that the diaphragm has the function of waterproof and breathable, to balance the internal and external air pressure of the speaker, and to improve the waterproof performance of the speaker. At the same time, the diaphragm itself forms waterproof and breathable micro-holes, avoiding the opening of large vent holes and the addition of waterproof nets, so as to ensure the sound performance of the diaphragm.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a vibrating membrane and a loudspeaker with the vibrating membrane. Background technique [0002] At present, electronic devices such as smartphones and smart tablets need to have dustproof and waterproof functions to meet the environmental requirements of daily use. Among them, wearable devices are more important in terms of waterproof requirements, such as wearing a smart watch for swimming, diving, showering, etc., which requires higher waterproof level of the device. [0003] Based on the waterproof requirements of electronic equipment, electronic equipment must be well sealed during design and assembly, otherwise there will be hidden dangers of water ingress. However, due to the heat generated by electronic circuits and chips, these heats will cause the air in the airtight device to expand. Since the sound chamber of the speaker communicates with the inte...

Problems solved by technology

However, due to the heat generated by electronic circuits and chips, these heats will cause the air in the airtight device to expand. Since the sound chamber of the speaker communicates with the internal space of the entire device, the expanded air will affect the work of the speaker and may produce low sound. , noise and other issues

In order to decompress and waterproof, the existing technology will open a vent hole on the diaphragm, and then paste a waterproof net on the vent hole, but the pasted waterproof net is easy to fall off, and the additional waterproof net will also affect the sound performance of the diaphragm. make an impact
