The overall background music mostly belongs to the traditional background music control mode, with constant pressure as the main factor. Generally, consider how many speakers the whole family needs to install first, then calculate the total power of the speakers, and then configure a special constant voltage amplifier. A power amplifier can drive multiple speakers, and the power amplifier and speakers adopt a constant voltage transmission mode (that is, they are connected in parallel like electric lights), and the sound generated by the constant voltage transmission mode belongs to mixed mono. Only in this way, the sound will not have obvious directivity. Nowadays, with the development of science and technology, the appearance of flat-panel audio and the development of smart home, modern family background music control system generally adopts split stereo control system to configure flat-panel speakers, which is also widely used in many smart home background music solutions. (For example: Feiyinbao household and Feiyinbao commercial background music control system based on microgram technology).
Split family background music system is to install a separately controlled background music controller in any room of the living room, including kitchen, bathroom, bedroom, study, balcony, children's room, chess and card lounge, gym and so on. , and transmit high-fidelity stereo music to each room through one or more sound sources. You can choose the sound source according to your own needs and control the volume of each room independently, so the functions are all operated on the panel and remote control, so that every room can hear wonderful music.
With the improvement of people's living standards, people pay more and more attention to the comfort and cultural taste of home decoration. Music has gradually become a new element of home improvement and one of the essential configurations of home improvement, and good background music is especially helpful for children's growth. For example, prenatal music and children's music or children's voice learning programs can be stored in the memory TF card of the background music controller, which makes children learn more easily and cultivates innate music art cells. Playing appropriate prenatal music will also promote the intellectual development of the fetus. The pressure of modern people's life is increasing. Besides having a warm environment at home after work, having good music can make people relax and work more efficiently. Especially the timing function in the control system, it is healthy to wake you up from sleep with music.
At present, there are many manufacturers of family background music. How to choose products that are suitable for you and cost-effective according to your own conditions requires us to analyze and understand the products of this industry and their supporting products. A complete family background music system should include three parts: 1. Sound source, controller and speaker.
First, the sound source part.
Sound source is the source of sound, which can be simply understood as the carrier of recording sound. The family background music system can freely choose the sound source, and computers, televisions and DVDs can all be used as sound sources. For the home type of Feiyinbao background music control system, you can choose 6 audio sources, 1 public * * * audio source (wired input), 1 3.5 connector input, and 4 local audio sources (built-in FM+ built-in 2G memory+). Moreover, the system can also use FM radio to upgrade the wireless transmission of audio sources, which can wirelessly transmit audio signals played by computers or other devices, and the FM of the controller itself. External 3.5 interface can be directly connected to mobile phones, computers, MP3 players, digital photo frames, etc.
Second, the controller part.
The family background music controller system is divided into two types: host type and split type.
For example, the host control of the parking stereo, a host distributes the sound source, and then uses a separate control to amplify the signal to the back of the room.
Generally, modern families adopt split control mode, and each family member has his own hobbies. Because of the age difference, his favorite music is different, so the split control is adopted, which not only meets the requirements of each family member, but also greatly reduces the cost. It is also very convenient to operate, such as Feiyinbao background music control system. For some old people or children who don't know how to operate, as long as the system is turned on, it will automatically play, or automatically switch between SD, U disk and TF card without adjustment. The sub-control system integrates sound source and power amplifier, and its volume is very small (86 bottom boxes with similar switches are installed). In particular, the use of flat-panel speakers. The whole home environment is not only beautiful, but also saves space. The sound sources are evenly distributed in the room and do not interfere with the conversation and chat between people. This is the enjoyment of modern home life.
Third, the speaker part.
Speakers play an important role in family background music. No matter what kind of background music system, it is finally realized through speakers. At present, the speakers used in family background music mainly include ceiling speakers, wall-mounted speakers (embedded) and flat speakers (mural form).
(1) ceiling horn. Ceiling horn is a widely used speaker at present, which can be divided into three types: ordinary, coaxial and adjustable high and low bass. In terms of sound quality, coaxial and adjustable speakers are much better, and the price is correspondingly more expensive. There are many brands of ceiling speakers, ranging from ten yuan to several hundred yuan, which is convenient to install. But if there is no ceiling in the room, you can't use the ceiling speaker.
(2) Wall-mounted speakers. In the past, wall-mounted stereos were used less because of their large size, single color and poor coordination with rooms. The emergence of embedded wall-mounted speakers has solved this problem. At present, the color of wall-mounted speakers is mostly white, which is in harmony with the wall. This kind of speaker is better than the ceiling speaker in sound quality, but because the bass is not limited, the dialogue between people will be slightly affected. Wall-mounted speakers solve the problem of no ceiling, but the installation needs to be opened on the wall, which leads to an increase in engineering quantity.
(3) Flat speaker. It is a relatively new product at present, and its sound mode is different from the paper basin structure of ceiling speakers. Flat-panel speakers are high-tech products in modern fields. The appearance of flat-panel speakers will truly realize ambient music, which will be the development trend of audio industry and will gradually replace traditional speakers in engineering and civil fields. For example, TVC flat panel speakers can be customized according to the style of home environment, which perfectly combines the environment with speakers. It can also be customized according to the size requirements of guests, and flat speakers with different sizes can be matched according to the size of different areas. In terms of sound quality, the sound field of flat-panel pronunciation is even, the sound quality is good, and it does not interfere with people's chat. The installation is very simple and can be directly hung on the wall. However, the price is relatively higher than that of ceiling speakers and wall-mounted speakers, but if you buy a set of products directly at the time of purchase, it will have great advantages in cost performance, even cheaper than buying ceiling speakers alone, and the sound quality and power matching are relatively standard.
