An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.

Electronic device

A keyboard device includes a substrate, a thin film switch circuit, and a trigger device having a rubber dome and a metal dome. The trigger device is configured to trigger the thin film switch circuit in response to an external force. The rubber dome is arranged to provide a first tactile feel during a first pressing process while the external force is exerted and provide a first rebound force during a first relieving process after the external force has been removed. The metal dome is arranged to provide a second tactile feel during a second pressing process while the external force is exerted and provide a second rebound force during a second relieving process after the external force has been removed.

Keyboard device

An electronic device includes a display module, a movable member, a base, and a biasing element. The display module has a housing and a guiding member fixed thereto. The guiding member has an angled surface, and the housing has an opening. The movable member is disposed in the display module and has a through hole. The biasing element is disposed in the through hole and adjacent to the angled surface. The base has a main body and a connecting member, wherein the connecting member is connected to the main body and detachably connected to the display module. When the connecting member is inserted into the display module through the opening along a first direction, the connecting member pushes the movable member to move along a second direction with respect to the housing, and the movable member forces the biasing element to contact the connecting member.

An electronic device includes an impedance detection circuit and a processor. The impedance detection circuit is configured for receiving a test signal, processing the test signal and detecting an impedance of a headphone speaker load by using the test signal to generate a detection result. The processor is coupled to the impedance detection circuit and configured for providing the test signal to the impedance detection circuit, receiving the detection result from the impedance detection circuit, and adjusting a voltage of an audio signal to be provided to the headphone speaker load according to the detection result.

Devices and methods for headphone speaker impedance detection

A portable electronic device includes first and second bodies. The first body includes a guiding rail, a restoring component, a first magnet disposed in the guiding rail, top and bottom surfaces. The guiding rail is connected between the top and bottom surfaces. The restoring component is disposed at one end of the guiding rail close to the top surface. The second body including a second magnet is pivotally connected to the first body for rotating from leaning on the top surface till leaning on the bottom surface. When the second body leans on the top surface, the first magnet is attracted to the second magnet to lean on the restoring component. When the second body leans on the bottom surface, an attraction force between the first and second magnets is greater than a restoring force provided by the restoring component so the second magnet moves toward the bottom surface.

Portable electronic device

A hinge structure including a first shaft, a second shaft and a moving component is provided. The first shaft and the second shaft respectively have a guiding portion and a first screw thread and a second screw thread located at the guiding portion. Each of the first screw threads is connected to the corresponding second screw thread. The moving component is respectively coupled to the two guiding portions. When the first shaft and the second shaft rotate with each other through the moving component to switch between a first state and a second state, the moving component is guided by the first screw threads and the second screw threads to move along a direction parallel to the first shaft back and forth.

Hinge structure

A control device and an associated method for driving a multi-function speaker supporting a plurality of predetermined functions including at least an audio function and a non-audio function includes a digital signal mixing block and a digital-to-analog block. The digital signal mixing block is arranged for receiving a plurality of digital input signals corresponding to the predetermined functions, respectively, and generating a digital mixed signal according to the digital input signals. The digital-to-analog block is coupled to the digital signal mixing block, for generating an analog driving signal to the multi-function speaker according to the digital mixed signal.
