Smart Bluetooth Speaker Chip Solutions

Smart Speaker

Smart Bluetooth speaker, as an upgrade product of traditional speakers, is an intelligent device controlled by voice for home consumers. For example, people can order songs, shop online, or understand the weather forecast through smart speakers. At the same time, it can also control smart home devices, such as opening curtains, setting the temperature of the refrigerator, advancing the water heater to warm up, etc.
 

Traditional non-smart Bluetooth speakers are generally controlled by remote control or body buttons. And the current smart Bluetooth speakers use the remote control is increasingly seen as a backup function. And the common control function is controlled through APP/WeChat/Alipay applet. And smart Bluetooth speakers are also compatible with gesture recognition, voice control, hand-waving induction, and other control methods. This means that companies in the development of smart Bluetooth speaker solutions, in addition to attention to WeChat, Alipay, APP, etc. for development, should also set up gesture recognition and voice control can develop the function. 
 

Smart Bluetooth Speaker Means of Communication

Smart Bluetooth speaker through Bluetooth, WIFI, NFC, and other information transmission methods to transfer information. NFC is usually connected at the moment of cell phone and speaker connection; simple and direct, there will be no complex use of the process. Similarly, some smart Bluetooth speakers also use an acoustic connection and transmission in a certain range; the quality and Bluetooth and WIFI are equal, only the cost of WIFI is slightly higher, but for the intelligent development end of the company, you can erase this difference. 

Smart Bluetooth Speaker Function Development

The smart Bluetooth speaker function contains an integrated machine sound machine, broadcasts the weather, alarm clock, and other common functions; in addition to this, but also has a read-aloud, intelligent seat, and even intelligent television sets and intelligent voice robot assistant functions. These functions can guide the smart Bluetooth speaker for voice shopping, voice information queries, voice chat, etc. 

Smart Bluetooth Speaker Key Technology

Based on the traditional speaker technology, there has been a upgrade technology on smart Bluetooth speaker. It has not only the basic technology development but also to integrate acoustic design, wireless technology, voice recognition, far-field pickup, semantic analysis. Not only technically complex but also more dependent on the music content platform support. All of this is inseparable from the small and convenient bass enhancement technology, wireless technology, and sound pairing code technology, as well as far-field voice wakeup recognition technology.
