Abstract: A method and a device for controlling a remotely controlled mobile platform and a readable storage medium are provided. The method includes: displaying at least one function icon and at least one control icon, where the function icon represents a control program for implementing a preset function, and the control icon is used to control a control terminal and/or a remotely controlled mobile platform to execute the control program; generating, based on a selection operation of a user on the function icon, the control program associated with the selected function icon; and controlling, based on an operation of the user on the control icon, the control terminal and/or the remotely controlled mobile platform to execute the control program.

Abstract: A speaker, a television provided with the speaker and a multimedia device are provided. The speaker includes a box body and a plurality of transducer units installed within the box body by means of parallel connection: front sound cavities of the plurality of transducer units are independent of each other, respectively; and the plurality of transducer units share one back sound cavity. The speaker possesses such advantages that it has a high sound pressure level output and a smaller power consumption, it is usable to reduce the back-cavity acoustic resistance, and it is usable to raise the lower frequency limit in the low frequency range.

Abstract: A mobile device, an action performing system and an action performing method can solve the problems such as inconvenient operation and ease of misoperation occurring in practicing action transfer with present multi-screen interaction technique. The mobile device includes: an executing unit, for performing an action of displaying an image and/or playing a sound; a processing unit, for acquiring optional information, determining whether to transfer the action to a fixed device based on the optional information, and transferring the action to the fixed device if the determination result is yes, otherwise not transferring the action, the optional information including a distance between the fixed device and the mobile device; and a first wireless communication unit, for enabling the mobile device to perform a first information exchange with the fixed device in a wireless manner, the first information exchange including sending information required for performing the action to the fixed device.
