Problems may be encountered with handheld electronic devices:
If the speaker and the receiver has no barrier protection in the process of long-term use will have water, dust adhesion in the speaker or the receiver, this will seriously affect the quality.
But sometimes handheld electronic devices need to use in the rain water and fog in the outdoor environment, even in the water . In order to let the water can not penetrate the equipment ,the design must be closed.
But the airtight design will affect the sound.
Because which will cause the interal pressure rapid changes , The pressure difference is mainly caused by two kinds of environmental change: rapid temperature changes, such as people from the warm with a handheld electronic device to very cold outside, there is the height changes quickly, such as handheld devices with the takeoff and landing situation. These differences may result in two kinds of performance problems:
A sudden drop in the temperature of the external environment causes a rapid drop or rise in the pressure difference between the interior and exterior, which causes the casing seal to withstand the enormous pressure rise and fall of the external environment. If things go on like this, repeated cycles of high / low pressure will make the seal is damaged, so that the water and pollutants into the equipment, the equipment failure.
Microphone or receiver without special design, because of pressure build-up by acoustic or acoustic chamber will cause stress on the microphone or the receiver, the voice input or output distortion or attenuation.
How LeaDer to solve the problem this problem -not only let the rain can not penetrate the equipment, but also effectively ease the accumulation of pressure it?
Our waterproof permeable membrane can be used to solve the above problems.
LeaDer waterproof breathable membrane to disperse PTFE resin as raw material, tensile ePTFE membrane, multiple small pore of the products by three-dimensional staggered, so that the gas can free import equipment, sound can be through a small pore diffusion sound. At the same time, small micro pore water, ratio of dust, so as to achieve the occurrence of water droplets, dust entering barrier devices.
At the same time, the equipment within the microphone sound Gould waterproof breathable membrane vibration, vibration with LeaDer water-proof sound transparent film and sound diffusion to the same equipment; the voice of the outside world can also cause LeaDer water-proof sound transparent film vibration, vibration Gould waterproof sound transparent film can also be induced by the receiver, thus the outside of the incoming sound equipment.
Three small pore LeaDer water-proof sound transparent film can make air molecules free swimming, so that the pressure inside and outside of the equipment quickly reach equilibrium pressure to effectively relieve the equipment due to temperature change, sea level changes due to the poor, relieve stress by the microphone or the receiver, achieve high fidelity sound transmission.
Application area
Storage requirements
1 avoid direct sunlight, avoid close to the heat source, avoid dust
2 storage time is not more than 1 years
Operational matters needing attention
1 the installation position of the membrane in erect direction, so as to avoid dust accumulation
2 in the installation of the position of the membrane to set a clear positioning line
3 installation surface roughness shall not exceed Ra1.6.
4 to ensure the environment clean, so as not to interfere with dust proof effect
5 to ensure that the installation surface is clean and dry.
6 avoid spiky components touching the membrane
7 please wear clean rubber gloves or fingerstall rubber operation, avoid direct contact with the fingers of membrane
8 use a blunt edge tweezers to avoid damage the membrane from the extraction of membrane
Extract the membrane from the profile
Methods 1：rolled up material, so that the membrane separated from the type material, separated about 1-2mm and then taken to extract the membrane
method 2： place the product flat on the table, stir up the membrane gently with tweezers after 1-2mm move the membrane
Place the membrane
The membarne accurately placed in the target limit range
If need replace the membrane , first clean the paste to paste the new membrane interval.
After place the membrane , with a finger with a pressure of about 30 thousand PA of pressure applied to the membrane for 5 to 10 seconds
In order to ensure the effect of paste, rubber auxiliary pressing tool should be used.
Rubber auxiliary tools should be consistent with the gum ring
Rubber hardness is about 30 degrees, the thickness can be 2 to 5mm
Pressure pressure of about 30 thousand pa
The auxiliary pressing time is about 24 hours
After installation check
1 whether the location is good
2 away from the waste material attached on the membrane, if there is should be cleared
3 tThere is no dust, foreign matter, if there is to be blown away
Remove defective membrane
If the production or use is found to have an defect situation, it is necessary to remove the damaged membrane.
95% medical alcohol or white oil can be use to remove stick on the membrane.
