1, delay delay and radiation problems, in the early wireless mouse, mouse delay is indeed a big problem, but with the development of the mouse chip and the application of wireless technology, in the general home or office use, the market The delay of the mainstream wireless mouse is not obvious, and it can meet the needs of such users. However, for professional gamers, most wireless mice may not be suitable. 2, replace the battery wireless mouse and wired mouse has one of the biggest difference, the wireless mouse needs to be powered by the battery, and the wired mouse can be powered by the computer. In addition, the mouse inside the battery, it will inevitably increase the weight of the mouse, affecting the friction with the mouse pad, the market's wireless mouse has a single and double AA batteries, there are also using the 7th battery. Therefore, battery life and wireless mouse weight are indeed a big problem.
3, game defects Wireless mouse is not suitable for playing games, this reason right? For some professional gamers or gamers who require high game operation, wireless mouse has no advantage over wired mouse, which is mainly reflected in the performance. However, there are also game mice specially designed for game players on the market, such as the Logitech G7. Whether the wireless mouse is suitable for playing games is actually more related to game types and user needs. Therefore, it cannot be completely denied that the wireless mouse is not suitable for playing games, but professional players using wireless mice have not appeared in competitive games.
4, pairing problem For the wireless mouse adopting 2.4GHz technology, in the first use, must go through the rate pairing process, for some users, compared with the wired mouse, this process may seem more troublesome.
5, the price has no advantage Early wireless mouse, expensive price is not acceptable to every consumer, but with the increase of wireless mouse products, the market has been on the low-end wireless mouse and wired mouse, but if the same grade Compared with wired mice, the price of wireless mice will be higher, so the price factor is also a reason why users do not buy wireless mice.
HIFU Piezoelectric Ceramic Parts
High Intensity Focused Ultrasound (HIFU) technology is to focus ultrasound on a single point to produce high energy, function on the dermis and SMAS layer of skin, stimulate the proliferation and recombination of collagen, effectively achieve the effect of compact contour and smoothing lines.
Focused ultrasound does not heat the skin surface, nor does it need to pass through the skin as a medium for the transmission of laser energy, so it does not affect the tissue on the skin surface and the tissue through which the laser passes, of course, there will be no excessive heat residue on the skin surface. In this way, the epidermis will not be affected by heat, which can reduce the Eastern people's thermal reaction easily, and greatly reduce the chance of scald. Focused ultrasoundtherapy produces thermal coagulation points in the SMAS layer, and the thermal effect diffuses outward from the coagulation points, so the heat source is concentrated in the SMAS layer to be treated. It can produce more collagen denaturation.
