Electromagnetic buzzer waterproof membrane material is a certain degree of tension

waterproof electromagnetic buzzer adopts buzzer waterproof membrane material for safety protection. The buzzer waterproof membrane material is a new type of polymer waterproof material (usually EPTFE electromagnetic buzzer waterproof membrane material), which has good air permeability, Promote the easy discharge of moisture and steam, and prevent internal condensation into water. The electromagnetic buzzer waterproof membrane sticker selects double-sided tape with good viscosity, which is not easy to fall off after installation, the electromagnetic buzzer waterproof membrane raw material also has good UV resistance and heat resistance and low temperature resistance. The electromagnetic buzzer waterproof membrane raw material can also effectively prevent pollution, waterproof, etc. The waterproof grade exceeds IP67 (it can be used after 1 meter water level is soaked for 30min), and even IP68 (it can be used after 3 meter water level is soaked for 30min). Electromagnetic buzzer waterproof membrane raw material is a very thin waterproof breathable sound permeable plastic film, has a good noise transmission effect, electromagnetic buzzer waterproof membrane material has a certain tension (tensile properties), under certain pressure can also effectively control the inner wall of the electromagnetic buzzer.

The common electromagnetic buzzers on the market basically cannot meet the needs of waterproofing. General buzzer as a sound element, need to have a sound hole to better transmit sound pressure (sound intensity). The presence of the pronunciation hole will cause water seepage in the inner wall of the buzzer. If there is too much water, it will endanger the normal start of the buzzer. Some electronic devices that use electromagnetic buzzers are mostly used outdoors. The outdoor changeable natural environment is likely to suddenly suffer from rain and snow. In other words, they are splashed by water, causing the pickup to leak water, endangering the waterproof of the buzzer. Therefore, the buzzer needs to select the raw material of the electromagnetic buzzer waterproof membrane to realize the reliability design of the buzzer waterproof structure, so that the electromagnetic buzzer has a very good performance index.

waterproof buzzer adopts buzzer waterproof membrane material for safety protection. Buzzer waterproof membrane raw material is a new type of polymer waterproof raw material (generally EPTFE electromagnetic buzzer waterproof membrane raw material), with good air permeability, promote moisture and steam easy to distribute, to prevent internal condensation into water. The buzzer waterproof membrane self-adhesive adopts double-sided tape with good adhesion, which is not easy to fall off after installation. Buzzer waterproof membrane raw material also has good anti-ultraviolet and heat resistance and low temperature performance. The raw material of the electromagnetic buzzer waterproof membrane can also effectively prevent pollution and water, and the waterproof grade exceeds IP67 (it can be used after 1 meter water level is soaked for 30min), and even IP68 (it can be used after 3 meter water level is soaked for 30min). The raw material of the waterproof membrane of the electromagnetic buzzer is a very thin waterproof, breathable and sound-permeable plastic film, which has a good noise transmission effect. The waterproof membrane material of the electromagnetic buzzer has a certain tension (tensile property), and can effectively control the inner wall of the electromagnetic buzzer under certain pressure.
