Abstract: A speaker device with a processing unit and a storage device for controlling the operation of the speaker device also has a speaker unit and a connection module. The processing unit adjusts the speaker unit to operate in a first sound mode based on the first frequency characteristic of the speaker unit, and detects whether the connection module is communicatively coupled with a sound device having a second frequency characteristic. The processing unit switches the speaker unit from the first sound mode into a second sound mode based on the comparison between the first frequency characteristic and the second frequency characteristic.

Abstract: The present disclosure provides a device control method, which comprises capturing, by a portable device, a first image of a specific area containing a number of electronic devices connected to a communication network; transmitting a connection signal to a selected electronic device on a device list containing all the electronic devices connected to a communication network; determining whether the selected electronic device is in the first image captured based on whether a response has been received from the selected electronic device; identifying the selected electronic device on the device list and the relative position of the selected electronic device on the first image captured upon determined that the selected electronic device is in the first image; and continuing the device identification process until all the connected electronic devices on the device list has been verified, to identify the relative positions of all electronic devices contained in the first image.
