Wearing headphones and following the rhythmic rhythm of music is the habit of many sports enthusiasts. When the crystalline sweat splash down the hair slip through the headphones, the trouble also comes: "sports sweat more, there are several pairs of headphones are seeping water screwed up!" Even the well-known outdoor adventure blogger has exclaimed: "Because of sweat infiltration with a dozen headphones broken!"
The reason for this is that the headset is not enough waterproof ability to cause.
International Protection Class Certification is a common standard for headset waterproof evaluation, its specifications are indicated as IPXX, the first value of X on behalf of the dust level; the second value of X on behalf of the waterproof level, level 4 can prevent splashing water droplets invasion, 5-6 level can be waterproof flow invasion (can be washed and cleaned), 7-8 can be immersed in the water for 0.5-1 hours is still intact, you can continue to use. If waterproof is the main consideration, sweaty sports enthusiasts elected IPX7 or above waterproof level headphones.
Piezoelectric pressure sensor solution
Waterproof and smooth
As a pioneer representative of sports headphones, the waterproof performance of TWS headphones not only lies in the shell package, but also tests the stability of its internal devices. Compared to other pressure-sensitive solutions, the emerging piezoelectric pressure-sensitive solution is slightly better in terms of structural design, assembly method and reliability.
Structure: advanced seamless design
After power on, the headset will produce a small internal "heat" phenomenon, some of the components on the market in order to prevent thermal expansion and contraction caused by their own deformation damage, will be retained in the design of a certain "gap" for the physical squeeze to provide space, such as water particles penetrate into the gap, it is very easy to damage the structure, affecting the normal operation of the components. If water particles penetrate into the gap, it is very easy to damage its structure and affect the normal operation of the components. Piezoelectric pressure-sensitive solution core device - piezo haptic actuator using advanced seamless design, fundamentally eliminating the gap, exclude water particles on the components to destroy the structural factors, not to give the sweat affects the headset touch to stay in the opportunity.
- High sensitivity, miniaturization
- Good consistency
High yield SMT process
With capacitance, resistance pressure sensing solution a class of materials need to be manually welded differently, AUDIOWELL piezoelectric pressure-sensitive solution in the piezo haptic actuator and conditioning chip are able to through the SMT (Surface Mounted Technology, that is, the surface mount technology) process assembly, and for the same overall SOC, directly for assembly, high efficiency, assembly of the whole machine cost is low, and effectively ensure that the one-time production yield and ESD requirements. Through the SMT process assembly of the piezo haptic actuator vibration resistance is much stronger than manual welding, in motion can also maintain sensitive touch performance, so that the headset touch with "steady happiness".
Reliability: automatic calibration function
At present, most of the solutions have not solved the consistency of the sensor, AUDIOWELL piezoelectric pressure-sensitive solution specifically to deal with this, so that the piezo haptic actuator with automatic calibration function, in the production process can be automatically inspected, to ensure that the product experience consistency.
The piezo haptic actuator has a small volume (1.5*1*0.3mm) and high sensitivity. In addition, in order to avoid the environmental impact caused by the differences in sensor parameters and the occurrence of headset manipulation errors, AUDIOWELL piezoelectric pressure-sensitive solution designed in this regard, targeted DSP processing module, fundamentally solve the problem of using the environment generated by the differences in pressure sensing. In other words, in the sweaty external environment, the transmission parameters of the piezo haptic actuators can also be continuously stabilized, always maintaining a high sensitivity level of touch control.
Personalized, customizable touch control
TWS headphones equipped with piezo haptic actuators will be endowed with powerful touch control skills, which can be preset with different touch modes corresponding to different functions to activate and deactivate, and also provide users with the dynamic experience of "motioning+touch" - no need to stop and use the buttons or knobs during the movement. The headset can be controlled by touching the outside of the earbuds to control music playback and calls without stopping to use the buttons or knobs during exercise. At the same time, AUDIOWELL provides customization services and looks forward to developing more interesting and intelligent touch control methods for the majority of users.
According to iiMedia Research report, "when exercising" is ranked No. 2 in Chinese netizens' application scenario for TWS wireless headset, accounting for 27.2%, second only to "anytime", with the rise of the wave of national fitness, the demand for sports-type TWS wireless headset will continue to expand! With the rise of national fitness wave, the demand for sports-type TWS wireless headphones will continue to expand. With the development of technology to promote headphones in the performance, stability and other aspects of the upgrade, TWS wireless headset touch control, sound quality, noise reduction, battery life and other basic experience will be significantly improved, to promote the further development of the industry.
