"How much power should the power amplifier need?" Many people think that bigger is better. But there are actually many considerations. On the one hand, power amplifiers with higher output power are bigger, more expensive and consume more power; secondly, do you really need such a high-power power amplifier? Does more power mean better sound quality?
The factors involved include the listening environment, the distance between the speaker and the listener, the efficiency of the speaker, and the power it can withstand, etc., which will affect the power requirements of the audio system for the power amplifier.
Now, we mainly explain "the efficiency of speaker'', it is the sound pressure obtained by inputting a 1W signal at a distance of 1 meter from the front of the speaker, which is the axis of the sound.
The efficiency of each speaker is different.
Generally speaking, the efficiency of the speaker is usual in the range of 82-88dB/w/m (dB = decibel). If the nominal efficiency is 86dB/w/m as an example, it means the speaker is at a distance of 1 meter from the sounding axis line (that is, directly in front of the speaker's front baffle), and the sound pressure will be 86dB when a 1W (watt) signal is input.
However, the sound pressure is inversely proportional to the square of the distance from the sound source, so if the general listening distance is estimated at 2 meters, the same speaker will only have 80dB sound pressure when the input power is 1W (the algorithm of dB is doubled every 3dB, and the distance is doubled. 1/4 sound pressure is -6dB).
So to be able to achieve the basic sound pressure of about 90dB for general listening, we need about 8W of power to have a sound pressure of 89dB. Therefore, if the speaker efficiency is not too low, generally speaking, a 10W power amplifier can listen to music normally without any problem.
Apple watchkit recently launched, we can more thoroughly understand the apple watch. However, what we want to talk about today is not wearable devices, but another technology - Wireless charging technology. We have been looking forward to Apple's adoption of wireless charging technology for a long time, but we didn't expect to adopt it on the apple watch first. However, this time, as usual, we regret Apple's first attempt at the new technology. This watch using tight coupling inductive charging technology seems to deviate from the original intention of wireless charging in its design - so that you can use wireless charging in any situation and share charging devices with other devices. The apple watch must be charged once a day, and it must be completed every time it is charged - a series of operations such as removing the watch, installing the charging device, plugging in the socket and so on.
The charging base of Apple's smart watch does not expose the charging contact. It adopts MagSafe magnetic suction technology similar to that of MAC laptop, which connects the induction coil and charging line built in the smart watch through magnetic suction. Compared with other smart watches, Apple keeps the integrity of its products by removing charging interfaces or metal contacts... It seems that this does not promote the development of the whole wireless charging industry? This is not the case.
Apples are ripening agents
Wearable devices are a niche market. The imagination in this regard has been launched, and athletes have basically entered the market. However, it is a pity that wearable devices always lack a killer application due to the limitation of endurance. Wearable devices are undoubtedly only a drop in the bucket for the huge scale of intelligent terminal devices. Their specification restrictions make the battery unable to grow. Their development towards intelligence must be accompanied by the increase of interaction frequency and energy consumption. This is an inevitable contradiction, which is more acute than smart phones. With the increase of the screen of smart phones, the fuselage also has space to put down larger batteries. Now, as a role of sharing the tasks of smart phones and emphasizing portability, wearable devices are far more urgent to solve the endurance requirements than smart phones. Moreover, it has been mentioned that the volume of wearable devices is far less than that of smart phones. Apple's admission has given a boost to such devices. It also pushed the problem of "how to make the smart devices in our consumers' hands work for a long time without charging every day" to everyone. The great versatility of wireless charging is undoubtedly the best solution so far. Of course, not in front of apple, it's just a compromise wireless charging solution for design.
Moto360 adopts the Qi standard, and the charging experience is undoubtedly better. It can share the same charger with Nexus series mobile phones, but this is far from enough. What we need is that our equipment can be charged inadvertently in our office environment, catering process, driving environment, family life, that is, most scenes of life (the meaning of wearable devices is that they don't need to take off charging) to make the charging habit more friendly. Because the current mainstream wireless charging standard Qi needs to be aligned with the coil position (the application of three coil technology has largely solved this problem) , the charging distance is also limited. Obviously, the charging requirements for wearable devices can not be met, and the a4wp using magnetic resonance principle can meet the requirements in function. However, it is just on track this year and lacks sufficient use attempts. This has formed a valuable technical gap. Apple's apple watch is like a ripening agent, which will greatly give birth to major players The maturity of standard technology to meet new needs.
New technologies are booming
In recent years, the continuous development and popularization of smart phones have greatly changed our daily life. Smart phones have increasingly become an indispensable part of our life. We can do more and more things on smart phones, and the performance of mobile phones is getting stronger and stronger. No matter how big the mobile phone becomes, the battery will always be the bottleneck limiting its continuous intelligence. In the battery revolution When we are far away, we need more wireless charging to meet our continuous extension of the disposable time of the equipment. Wireless charging technology gives us a possibility to abandon the disconnected materials and do not have to consider the charging problem at all. In the field of wireless charging, there is no unified standard in the field of wireless charging, and there are three existing standards PMA (power matters alliance), Qi, a4wp (Alliance for wireless power) are all trying to become the final standard in the world. I believe that all people who are familiar with the wireless charging industry will not be unfamiliar, so I won't repeat them one by one. In recent years, many exciting new technologies have emerged.
In order to completely solve the problem of requiring the placement distance and position of mobile phones when implementing wireless charging, WiTricity company of the United States has introduced the wireless charging technology using magnetic resonance, which can keep the mobile phone charged for a distance from the charger. At the same time, the position requirements are not so strict, and can charge multiple devices at the same time. It has been trial produced on ces2013 A number of wireless power supply products using the company's magnetic resonance technology.
Energy, a wireless charging technology research and development company, introduced a wireless charging technology called wattup not long ago. Users only need to add their own intelligent device with a special external receiver or put it in a special protective sleeve. Later, the specially managed application can detect whether there is a wireless charging device within 15 feet of the transmitting device of the charging station, and then just start the program Even more gratifying is that the company announced at the end of last month that the technology will soon be applied to Haier household appliances.
Meredith Perry and Nora Dweck, two sisters who graduated from the University of Pennsylvania, founded ubeam. Ubeam's idea is to use ultrasound as the medium. The process is to first convert the electric energy of the charger into ultrasound, then capture these ultrasound at the other end with a device to convert back the electric energy, and then connect the receiver to the device to realize charging, which is as simple as WiFi , in order to support its commercialization, the startup just completed a round of financing of $10 million at the end of last month.
