The gauges of different car dashboards are different, but the conventional gauges of general cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging meter, etc. In modern automobiles, automobile instruments also need to install voltage regulators, which are specially used to stabilize the voltage of the instrument power supply and suppress the fluctuation range to ensure the accuracy of automobile instruments. In addition, most of the instrument display is based on the sensor, and the sensing device changes its resistance value according to the state of the monitored object, which is expressed by the instrument. The most conspicuous thing in the dashboard is the speedometer, which indicates the speed of the car in km/h (km/h). The speedometer actually consists of two tables, one is a speedometer and the other is an odometer.

The car instrument looks simple, but it is not. As a vehicle information center, the screen is its display carrier, and the displayed content is its core. The display content comes from each electronic control unit on the vehicle communication system, which can be regarded as a display window of the vehicle electronic system integration capabilities. This square-inch area not only reflects the technical strength of the engineer’s design, but also shows the designer’s aesthetic perspective. It can provide automotive OEMs with higher added value of electronic products, match their models with more perfect personality, and provide consumers with more Diversified choices and personalized driving experience.

Whether it is the most common hybrid instrument in the industry or the digital instrument that is gradually emerging in the luxury car market, from the perspective of the design pattern, both symmetrical and asymmetrical layouts can be adopted. Symmetrical design, for example, the speedometer and tachometer are located on the left and right sides, and the fuel gauge and temperature gauge are placed below. If customers need more pointers, they can provide oil pressure (O), battery voltage or power (B), and leave the middle for information settings, alarms, and entertainment information. If there is still room, you can put some alarm symbols or simple gear functions. Asymmetrical design can make the instrument configuration more patchy. For example, in a hybrid instrument, the TFT display is placed on the right instead of in the center.

A modem is an electronic device that modulates a digital signal to transmit an analog signal, and demodulates the received analog signal to obtain a digital signal. Its goal is to produce an analog signal that is easy to transmit, and the original digital signal can be restored through decoding. According to different applications, modems can use different ways to transmit analog signals, such as using fiber optics, radio frequency radios or telephone lines.

Use NETGEAR's latest cable modem to get newer and faster network speeds from cable providers, and improve WiFi performance with two-in-one devices such as N450 cable modem routers.

A modem is a box that connects your home network to the wider Internet. The router is a dialog box, which enables all your wired and wireless devices to use the Internet connection at this time, and enables them to communicate with each other without going through the Internet.

1.Different material forms

Wi-Fi is a kind of electromagnetic wave, which cannot be perceived by the human body.

A wireless router is a physical device that can be used by humans daily.

2.Different definitions.

Wi-Fi is also called "mobile hotspot" in Chinese. It is a trademark of the manufacturer of the Wi-Fi Alliance as a product brand certification. It is a wireless local area network technology created in the IEEE 802.11 standard.

The wireless router is a router with wireless coverage function for users to surf the Internet.

3.The subject is different.

Wi-Fi is for various electronic digital devices, personal computers, game consoles, MP3 players, smart phones, tablet computers, printers, notebook computers and other peripheral devices that can access the Internet wirelessly.

The wireless router is to release Wi-Fi signals for people to use, and to build a network, its main body is people.

4.Different functions.

Wi-Fi can be simply understood as wireless Internet access. Almost all smart phones, tablets and laptops support Wi-Fi Internet access, and it is the most widely used wireless network transmission technology today.

The wireless router is used to convert and release wireless signals. The router has the function of judging the network address and selecting the IP path. It can establish a flexible connection in a multi-network interconnection environment. It can be connected to a variety of different data packets and media access methods. Subnet, the router only accepts information from the source station or other routers, and is a kind of interconnected equipment at the network layer.

In short, the router will establish a network between the computers in your home, and the modem will connect the network and the computers on the network to the Internet. When you connect to Wi-Fi, you are actually connecting to a router, which forwards traffic between the Internet and the computer.

Benefits of car speakers
Upgrade your stereo system. There are many issues that car manufacturers need to consider when designing a fully functional vehicle. Sometimes, it doesn't take much effort to create better-sounding speakers for cars. The good news is that you can buy aftermarket speakers to improve the sound quality.
Experience wonderful music. Have you ever felt that you are not getting the most from your favorite songs? Well, it is very likely that your current car speakers are not capable of handling different notes. Consider modifying the stereo speakers to enjoy stronger bass and brighter music.
Enjoy driving. If you spend most of your time in the car (whether it is work or leisure time), then good music with high-quality speakers can eliminate the troubles of driving. A set of high-quality car speakers will enhance the stereo effect and preserve the basics, thus bringing you a good listening experience while driving.
Space friendly. Aftermarket speakers will not take up too much space in your car. A set of two on the door or under the seat is sufficient. If you are concerned about the size of the space, you can also choose a smaller speaker instead of a large woofer.

Types of car speakers
Combination speaker
Combining speakers provides the best audio experience, but the drivers are not always together. Each component is placed in a different part of the car and installed in a different way to improve the user experience. Possible arrangements might be a woofer on the side of the door, a subwoofer in the trunk and a tweeter in the dashboard. The crossover ensures that the higher frequencies are directed to the tweeter, while the woofer can handle the lower frequencies.

Coaxial (full range) speaker
Coaxial speakers are easier to install and are reasonably priced because every component is built into the system. It consists of a woofer that handles low and medium frequencies and a tweeter that handles high-end frequencies. The drivers are in the same location, and some models place the tweeter above the woofer or rotate it to the left so that it can be tilted in different directions. Coaxial speakers provide a better listening experience than factory speaker systems.

Coaxial speakers are the cheapest and most common model. These speakers are easy to install, but usually produce lower sound quality. …They integrate the midrange by integrating the woofer (for low-pitched sounds) and the tweeter (for high-pitched sounds) into one unit.

You may need to replace the speakers in your car, especially if your car is older. This is not always essential for high sound quality, however. You can replace the speakers of your car for $70 to $100 or you can purchase a complete component speaker system, complete with crossover, tweeter and subwoofer, for $800.
