A wireless car charger mount includes a magnetic adsorption portion and two clamping members provided on symmetric sides of the magnetic adsorption portion. The two clamping members are arranged in parallel, and the clamping members and the magnetic adsorption portion are perpendicular to each other. The clamping members are detachably connected to the magnetic adsorption portion through a steering structure, and the clamping members are adjusted and fixed in any direction on a vertical line perpendicular to the magnetic adsorption portion. The present disclosure solves the problem that when a mobile phone is designed with a built-in magnet, a magnetic force is greatly weakened due to the installation of a mobile phone case, such that the mobile phone cannot be firmly fixed on a magnetic adsorption support, and falls from the magnetic adsorption support easily, which affects the fixation of a vehicle-mounted mobile phone.

The disclosure provides a speaker applicable to be fixed on an arched surface. It comprises a sound making member and a fixing frame connected therewith. The sound making member comprises a connecting frame, a magnetic element arranged at the front portion of the connecting frame, and a damper arranged at the rear portion of the connecting frame. The fixing frame is arched-shaped and fixedly connected with the back side of the connecting frame. It is arranged with a plurality of mounting holes, through each of which a fastening component can pass. It is designed to achieve an optimized box volume of the speaker box, and effectively simplifies the development of the moulds for the main body of the speaker box. It has merits such as reliable and convenient fixation, stable structure, convenient attachment and detachment, improved sound quality and sound effect.

A computing device and a computing system for digital currency are disclosed. The computing system comprises: computing devices (comprising first and second computing devices) each comprising two ports; and a signal transmission path connecting the computing devices in series. Each computing device is connected to the signal transmission path via the two ports. The first computing device is configured to receive, from the signal transmission path through one of the two ports, a signal specific to an address of the first computing device to a local storage device thereof. The second computing device is configured to receive, from the signal transmission path through one of the two ports, a signal to a local storage device thereof, and forward the signal, which is not specific to an address of the second computing device, or an adjusted version of the signal to the signal transmission path through one of the ports.
