Is it still in the networked control? It's said that this smart lamp is sound with sound.

36 krypton news, if you have used the city's smart lights, you must know how painful the process of networking is: Zigbee needs to network or buy a gateway. Even if Wi-Fi needs to lose the password, Bluetooth can only be one to one connection; the focus is to try many times to succeed.

Dissatisfied with these smart lights on the market, Zhang Lei had the idea of doing a really good lamp after leaving 360 in 2012. Now this "Hey light!" It has already completed the development, is about to be produced. Its biggest feature is that the equipment is not "connected", and the scavenging is used.

"Hey light!" Also using mobile phone control, Zhang Lei feels that in a long time, the phone is still the best smart home controller, but the way the hardware products communicate with the mobile phone can be more diverse. Compared to Bluetooth, WiFi, Zigbee, sound is more common, sound on the phone is more consistent and general, there is no compatibility problem, and the use of sound is easier for everyone. So, "Hey light!" Sound is chosen as a way of communication.

The most direct advantage of doing this is without a pairing connection, no need to configure the WiFi password, open a web page, or direct the control sound (you can use the control voice down) to the "Hey light!" Control. The operation is simple, direct and effective. The only requirement is that the user's mobile phone should be able to play sound.

As for the accuracy of the sound transmission signal, it is not necessary to worry too much. Sound transmission of data has a long history, from the earliest DTFM dual audio dial-up, MODEM Internet access, and FAX fax, all of which use digital sound to transmit information. Before the Internet has a very popular application of Chirp, is also the use of sound files.

The difficulty is that there are no chips or processors developed specifically for sound transmission in the market. After all, this is too small. "Hey light!" The existing Bluetooth chip is reformed and the sound transmission is realized on the basis of it. It is not difficult to understand that the Bluetooth headset can also transmit sound data.

Compared to the current smart lights on the market, "Hey light!" The cost is much lower. The latest edition is a double color lamp, which can be sold for 39 yuan. The team is still trying to achieve a monochrome price of 19 yuan. As for sales, in addition to the online business to attract customers from the geek, Zhang Lei hopes to be able to put the test board on the online, let the users play, realize the self-help order, and expand the ordinary users.

In fact, there are many products that can be controlled by sound, such as sound control socket, sound control self timer, sound control toy, sound control robot and so on. Zhang Lei felt, "Hey light!" Only one start, light is the longest used product in the family, it is very suitable to cut in; if it is proved right, the product may open its own chip in the future, by then the price of the lamp can be lower, and the chips and plans can also be sold to more manufacturers.

Hey. Light! There are four products, which are:

1) normal white monochrome, which is the daylight that we often say, can control 10 levels of brightness, and support three separate groups of A B C.

2) warm white monochrome, the family's common yellow light, can be 10 level brightness control, support A B C three separate groups.

3) cold and warm double color, support from normal white to warm white five level light adjustment, suitable for different home scenes lighting, 10 levels of brightness adjustment, support A B C three separate groups

4) RGB full color, can support continuous mixed light adjustment and brightness control, built in 10 different scenes of the light effect. Three independent groups of A B C are supported.
