There is no music in the sound of a sound system. This is the dividing line between Hi-End and non-Hi-End, because music is the soul of the Hi-End system.
The system is not very musical, this is a subtle problem depending on the equipment manufacturing design, matching and application adjustment process. It is not safe depending on the price of the system. Of course, it is not entirely dependent on the components. The quality and weight of the equipment. There are even a lot of mid-range stone machine systems, and even some high-priced digital-crystal systems, there is a "giant" type of water, in terms of compliant and tonality, the sound is also very standard, listen The hovering of the aircraft in the effect soundboard, the trajectory of the projectile launching, and the sound of the broken glass are all very good. The scene feels good. There is no particularly disgusting noise in this system, but for music lovers, especially It is a classical music lover and a fan. When listening to music, I always feel that there is a lack of listener "taste wax". We call this system poor in music.
As far as the current general manufacturing and application level is concerned, the musical sense of the amplifier is easier to be better than that of the stone machine. The music of the black disc analog (analog) phonograph is easier to do than the CD digital (digital) phonograph, so that There are still many high-level enthusiasts who are very identifiable, who are obsessed with the system of the amplifier and the black film player. They respect the sound of the music as "bile", and they sneer at the digital crystal system, even disdain one. Gu, all swearing that the sound they made is "digital sound", "crystal sound".
What is musicality?
Musicality is the sense of music. So, what is the “music sensation� This is indeed a vocabulary that is difficult to define. We can only say that music is a listener with musical art appreciation and a subjective and joyful feeling for the beautiful content of music. This beautiful connotation may include rhythm, harmony, balance and many other unique temptations.
Music is a huge and wide-ranging thing formed by thousands of years of development and exchange in the world. It can be divided into two major categories: vocal music and instrumental music. Vocal music is a voice that is sung or sung by people. The singer has the sounds of men and women, as well as men and girls. According to the number of singers, there are solo, sing, and sing chorus. There are low, medium and high treble according to the voice. According to the singing method, it is divided into classical vocal singing, national singing and popular singing. Instrumental music is music formed by single or multiple musical instruments. There are quite a variety of musical instruments, which can be roughly classified into stringed instruments by type. Small, medium, big, bass, Chinese music, etc.), woodwinds (flute, piccolo, clarinet, oboe, British tube and various Chinese cymbals, flutes, locks, cymbals, etc.) , brass instruments (small, horn, trombone, large, etc.), keyboard instruments (piano, celesta, organ, keyboard, etc.), plucked instruments (sage, guitar, mandolin, Chinese music, Yueqin, Sanxian, and Zheng, Guzheng, Guqin, etc.), percussion instruments (there are timpani instruments, bells, xylophones, etc.: the monotonous percussion instruments have drums, snare drums, cymbals, cymbals, triangle irons, music boards, tambourines, Sand ball, etc.), instrumental music can be divided into solo according to the playing method , ensembles, concertos, and symphonies. Each type of sound has a decent sense of music.
How to accurately listen to the musicality of the system
To listen to the sound of a sound system, it is best to listen to the various vocal and instrumental works mentioned above, but this requires a lot of sound source software, and it takes a long time to listen. So is there a convenient way to listen to the music of the system more accurately? We think it is enough to concentrate on some of the most representative music. According to the author's many years of experimental experience, instrumental music is more sensitive than vocal music in identifying music sense, and it is also scientific and standard: in instrumental music, it is mainly through the sound of two instruments. These two instruments are the violins that are known as musical instruments and the pianos that are known as the king of musical instruments. A well-known, well-recognized, well-recognized violin disc, the violin sound released in a real Hi-End system is simply beautiful, its soft color makes you think of velvet, it The fresh taste reminds you of a freshly peeled, watery fresh lychee that rolls into your mouth. It is bright and not irritating, smooth and not full of fleshy, fleshy and proud, and soft and soft. In the midst of a sudden jump, the extension, sliding, turning, smashing, rubbing, tremor, frustration, chords, and resonance of the piano can all be re-emerged. In the thousands of violin playing skills, any superb The performers have unique personalities that others can't imitate, just as there is a group of beautiful young girls who are beautiful, heart-rending, pure and not eating the fireworks in front of you, standing in front of you, seduce you stunned, straight Swallow, but they are so colorful, every pretty face is different from other people... This is the musical sense of the violin.
The piano's Hi-End music is full of masculine, bodybuilding, elves, agitation, crispy, clear, and thunderous when hitting. The sound can resonate with the entire auditorium; when it's relaxed, it's like a blue wave, no disease, no disease. . The wonderful sound of the piano, of course, makes us face like a white horse prince who is standing and seeing a number of women who are insane. However, only a good piano sound can give people a very elegant beauty. If the quality of the sound system is poor, then listen to the piano taste and chew wax, without any attractive musical appeal.
There is a subtle balance of sound between the violin and the piano. If the sound of the violin is too soft and too greasy, the system often makes some kind of wood-squeaking sound when playing the piano sound. On the contrary, if the piano sound is too crisp and does not have a certain weight texture, then When replaying the violin sound, there will be an unsatisfactory rubbing wire hard sound, which will lose the musical beauty.
A system, if the replay of the violin and the piano has a very good sound, is very musical, then basically speaking, the system will not have a big problem in the music when playing back any music. Of course, you can also put a few symphonies, male and female soloists, as well as "night deep", "bumpy gongs and drums", "ghost drums" and other music films with gongs and drums to supplement the sounds, so that the evaluation of the system's musicality will be even more Objective and comprehensive, WeChat: cnhifi.
What is 5G CPE?
5G CPE is a kind of 5G terminal equipment. It takes 5G signals from a carrier's base station and converts them into WiFi or wired signals, allowing more local devices (phones, tablets, computers) to access the Internet. It can be seen that 5G CPE is similar to the function of the "optical network unit" for home fiber broadband access.
What is a WiFi router?
WiFi routers are also known as wireless routers or access points.
A WiFi router acts as a Wi-Fi transmitter. It connects directly to a modem, router or switch via cable. This allows it to receive information from the Internet and transmit information to the Internet. Phones, tablets, laptops and other devices can pick up its Wi-Fi signal and then connect to the Internet.
What is the difference between 5G CPE and WiFi router?
The 5G CPE is actually a combination of a 5G modem and a WiFi router. With an independent 5G CPE, the device can access the Internet directly through the WiFi signal or the LAN port of the CPE. Of course, the 5G SIM card needs to be inserted into the SIM card slot of the CPE. However, a WiFi router will not be able to provide Internet access without connecting to a modem or router via cable.
To provide users with greater flexibility and reliability, many 5G CPE routers not only support 5G networks and 4G LTE networks, but also come equipped with WAN Ethernet ports for surfing the Internet. For local networks, WiFi 6, WiFi 5, and LAN ports are usually supported. Some models, such as the Hocell 5G CPE M111, are also equipped with telephone ports for VoLTE/ VoNR voice services.
What are the advantages of 5G CPE over ONU?
ONU is a kind of CPE, and the difference between ONU and 5G CPE is that the former connects to optical fiber access network equipment, while 5G CPE connects to 5G base stations.
There is also a question, since there is an ONU, why do you still need 5G CPE, and will 5G CPE replace ONU?
Let's start with the conclusion, of course not.
The current 5G CPE products all use the same or similar 5G chips as 5G mobile phones, have strong 5G connectivity, support SA/NSA networking, and are compatible with 4G/5G signals. In terms of speed, 5G CPE is similar to ONU.
The advantages of 5G CPE
1. Mobility and
Unlike traditional ONUs, which can only be used in fixed locations, 5G CPE can be "mobile." Where there is a 5G signal, 5G CPE can be used.
For example, when we go on a family vacation to a suburban estate, we can use 5G CPE to set up a Wi-Fi 6 high-speed hotspot that allows all family members to go online and share videos on social networks.
Another example is when a company is away at a trade show, it can use 5G CPE to provide Internet access to visitors and employees.
Traditional "fibre broadband" is relatively easy to set up. You go to the sales office and request a package, and then you can open it. But cancelling is tricky. Today's broadband services have a contract period. Before the end of the agreement period, you can not arbitrarily stop it. If you need to move, you have to switch to fiber broadband, which is also very troublesome. As for 5G CPE, as long as you have a 5G mobile phone SIM card, you can get high-speed Internet access.
For young people who are renting, as well as small businesses that need Internet service, 5G CPE is an ideal choice because of its mobility, fast Internet service registration and termination. 5G CPE is also suitable for remote areas or places with difficult terrain where fiber is virtually unavailable. Due to its large area and small population, many parts of the world began to use CPE long ago. They use 5G Outdoor CPE to receive signals from base stations and convert them into raw signals to access the Internet.
5G CPE can be upgraded to small base stations
5G CPE modifies 4G or 5G as a WiFi hotspot. WIFI devices can be converted via 5G CPE to access 4G or 5G networks.
Further, the WIFI hotspot, including the information processing and transmission within the CPE, is divided into 2 completely separate channels. The internal network channel has its own wi-fi, which is supervised by a person, and also has an account password verification. The external network channel is regulated and managed by the carrier. Two-way verification, remote monitoring, encrypted transmission, vibrant passwords, strict isolation of software and some devices to meet carrier-grade security requirements, complete isolation of indoor and outdoor wi-fi, extrannetwork-channel authentication of customer SIM cards,
5G CPE can be upgraded to a small base station, with both WiFi LAN and micro-base station functions. Good signal at the window, negative signal inside the car. Install a 5G CPE micro-base station by the window of your home and connect it to a power supply (or bring your own power supply).
It can access 4G and 5G networks through the CPE's external network. The phone charges, SMS charges, and information charges generated by the CPE are included in the phone SIM card number, but are not included in the CPE device. Peripheral WIFI devices without SIM cards, computer tablets (generally with WIFI), without wi-fi can get the USB user interface wi-fi card, through the WIFI Intranet access to 4G/5G network, resulting in traffic charges Input number corresponding to the CPE SIM card.
5G CPE micro base station, no matter where you go, as long as there is a 4G/5G signal by the window, there are mobile phones indoors, there are other terminal tools with SIM cards, and WIFI, you can call the Internet standby to solve the problem of indoor invisible. WIFI tools without SIM cards can also pass through the Intranet.
5G CPE applications
1. 5G CPE will act as a smart home gateway
In addition to providing Internet access, 5G CPE will also act as a smart home gateway in the future.
The demand for home routers has been the focus of competition among many vendors, because the router itself brings profits, as it is the gateway to the entire home network service and the entry platform for digital home operations. The 5G CPE serves the same purpose as a router. It will be the intelligent gateway for the unborn 5G family and the fulcrum for the intelligent life of the whole family.
With 5G CPE, users can control a variety of smart devices in their homes and connect everything, significantly enhancing the life experience of family members.
5G CPE has great potential for enterprise demand
In addition to consumer demand, 5G CPE has a very broad operational prospect in terms of enterprise demand.
Take smart factories, for example. In the future, all the devices and gears in the factory will be networked. 5G CPE can act as a unified traffic inlet and outlet for all devices in an area (shop floor), providing low-cost, high-speed network connectivity for these devices.
With the increase of application scenarios, 5G CPE will support more communication protocols other than 5G (such as Bluetooth, UWB, etc.), and truly become the control center of all devices.
3. Pipe network monitoring
Urban heating monitoring, natural gas network wireless monitoring, urban water supply network monitoring.
conclusion
All in all, 5G CPE is very important for both households and businesses.
With the full rollout of 5G network construction, 5G signal coverage is getting farther and farther. The demand for 5G CPE will continue to increase, and there will be more and more application scenarios around 5G CPE.
