Vibrating diaphragm and loudspeaker

Abstract

The invention provides a vibrating diaphragm which comprises a vibrating diaphragm main body, the vibrating diaphragm main body comprises a fixing part on the outer side, a folding ring part which isarranged on the inner ring side of the fixing part in a protruding mode and can generate elastic deformation and an inner side part located on the inner ring side of the folding ring part, and the vibrating diaphragm main body is made of a waterproof breathable material with waterproof breathable micropores. The invention further provides a loudspeaker with the vibrating diaphragm. According to the technical scheme of the invention, the vibrating diaphragm main body is made of the waterproof breathable material with the waterproof breathable micropores so that the vibrating diaphragm body is provided with the micropores, the size of the micropores is between that of water molecules and that of air molecules, so that the air molecules can smoothly pass through the micropores, meanwhile, thewater molecules are effectively prevented from passing through the micropores, the vibrating diaphragm has waterproof and breathable functions, internal and external air pressures of the loudspeakerare balanced, and the waterproof performance of the loudspeaker can be improved. Meanwhile, the vibrating diaphragm forms waterproof breathable micropores, thereby avoiding the forming of larger air vents and the additional pasting of a waterproof net, and guaranteeing the sound production 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
