Audio

A device interaction method includes when an electronic device is in a video call state, that the electronic device may display a dialog box or a control. In response to an operation performed on the dialog box or the control, the electronic device interacts with another device in a same local area network such as switching a video call from the electronic device to a smart television or performing projection on a smart television.

A left atrial appendage (LAA) occluder includes a sealing portion and a fixing portion connected to the sealing portion, and one or more sealed seed sources encapsulated with radioactive particles. The sealed seed sources are arranged on the sealing portion and/or the fixing portion () and configured for forming an annular isolation band on an inner wall of an LAA after the radioactive particles are released. The annular isolation band is configured for blocking the electrical signal conduction between the LAA and a left atrium. In the LAA occluder, the annular isolation band is formed on the inner wall of the LAA by the release of the radioactive particles in the sealed seed sources arranged on the sealing portion and/or the fixing portion.

A stereo microphone speaker includes a Printed circuit board, a middle housing, and a handle body. An audio frequency dividing module and an audio playback module are arranged at end surfaces of the Printed circuit board. The handle body includes a handle rear cover and a handle front cover, and an interior of the handle front cover is fixedly connected with a tweeter mounting cavity. An interior of the tweeter mounting cavity is provided with a tweeter. An interior of the handle rear cover defines a subwoofer mounting cavity. An interior of the subwoofer mounting cavity defines a subwoofer, and an upper end of the middle housing defines a silicone microphone installation fixing groove. A silicone microphone support is provided inside the silicone microphone installation fixing groove, and an interior of an upper end of the silicone microphone support is provided with a microphone.

An audio device includes a casing, a handle frame downwardly extended from a bottom side of the casing, a speaker assembly and a PCB board are received in the casing, and a microphone supported on the casing in a dynamic manner for preventing a vibration of the casing directly transmitted to the microphone. The microphone and the speaker assembly are electrically connected to the PCB board, such that the speaker assembly is adapted for instantly play back a sound signal collected by the microphone. The audio device of the present invention has an advantages of high impedance, good sound quality, and strong omni-directional ability, such that the electro-acoustic conversion effect and overall performance of the audio device is enhanced. At the same time, the audio device has a built-in speaker to instantly play back the sound collected by the microphone so as to fulfill different applications.

Audio device with dynamic microphone and speaker

The present invention discloses a spherical-screen device, a spherical-screen playing system and an image generating method for image rectification. The method includes the steps of: equally dividing an arc curve of a spherical screen, which corresponds to a radian of 90&#xb0;, into a plurality of segments; equally dividing a straight line of a planar image corresponding to the arc curve into a plurality of segments, the number of the segments of the straight line being equal to the number of the segments of the arc curve; assigning an image parameter of a first point in the planar image to a third point in a planar image; and connecting a sphere center with a second point of a to-be-displayed image position on the arc curve that corresponds to the first point, a point falling in the planar image being the third point.

A pressure cooker includes a cooking pot ( ) and a lid ( ) removably attachable thereto by interlocking radially-extending circumferentially-spaced locking flanges on the cooking pot and lid. The lid and cooking pot further include handles to facilitate application of the lid to the cooking pot, and safety interlocks which vent the interior of the cooking pot to the atmosphere at all times except when the lid is securely locked to the cooking pot, and also prevent opening the lid when the interior of the cooking pot is pressurized. The lid further includes a manual pushbutton ( ) to produce a rapid-release of the pressure within the cooking pot when the lid is to be removed.
