The first method is two-fold. If the player feels the temperature of the player is relatively high during use, and it takes about an hour or so to disconnect the box, it is presumed that the network is unstable due to heat. Therefore, we must use our small method, that is, the ice and the fire are heavy, you need to use the bottle of water in your home and then freeze it into ice, and then put it on a fresh-keeping bag (or the condensed water will wet the box). Put it on the top of the player, you can, start the test ~~~ miracle occurred, tested for a half-day once did not drop. The follow-up days are still very stable. This is very simple, it is to use the cooling method, everyone can play on their own, to achieve their goals.
The second method is that the magic height is one step higher. In fact, the method is similar to the first one. It is also an elevation box. When the box is in use, you put the four corners of the box up. This is very good. Heat dissipation. You can use a drink bottle cap or something else. As long as you can ensure good heat dissipation during use.
The third type is software support. For software support, system software is used to help enhance WIFI enhancement. You can go to Baidu to search and install “wifi enhancement†software to ensure that the box will release 20% of wifi receiving capacity (software introduction , actual measurement useful), improve wireless signal strength. Or install the "wifi analyzer" software and adjust your router's transmit channel based on the analysis results to ensure that the transmit and receive conditions are optimal.
Of course, there are many ways to improve the box's performance and network status. Consumers need to dig in slowly. After all, HD smart boxes are a new product that has just started in the Chinese market. Many of the shortcomings need to be consumed. To understand. There are several small ways to hopefully help consumers watch the live box movies you want to watch.
Piezoelectric Ceramic Ring
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
