Optical transmitting apparatuses are disclosed. In in an implementation, an apparatus comprises an array light source that includes M*N light sources. An included angle between any column of light sources in the N columns of light sources and any row of light sources in the M rows of light sources is predetermined. The array light source is located on a first side of a collimating lens, a plane on which the array light source is located is perpendicular to an optical axis of the collimating lens, and a distance between the plane on which the array light source is located and a center point of the collimating lens is a focal length of the collimating lens. An rotatable scanning mirror is located on a second side of the collimating lens, and a center point of a reflective surface of the scanning mirror is on the optical axis of the collimating lens.

Optical transmitting apparatus and electronic device

A wireless communication system includes a number of peripheral devices, a wireless communication device, and a terminal. The wireless communication device includes a first communication module and a second communication module. The second communication module includes a host unit and a device unit. The host unit is used to be wirelessly connected to the peripheral devices. The terminal supports the first communication protocol is used to connect to the first communication module, and the terminal supports the second communication protocol is used to connect to the second communication module via the device unit thereof. A method using the wireless communication system is also provided.
