20220225001 | AUDIO DEVICE HOUSING - An audio device includes a circular cover comprising a top and a bottom, a circular screen rotationally engaged with the bottom of the cover, and a circular shroud removably engaged with top of the cover. The top of the cover includes a plurality of mounting holes. The mounting holes may include a plurality of holes in a VESA pole mounting pattern. The mounting holes may also include a plurality of cable mounting holes configured in a square pattern having greater spacing than the VESA mounting pattern. The audio device may include a plurality of microphones and/or one or more loudspeakers. | 2022-07-14 |
20220225002 | LOUDSPEAKER APPARATUS - The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook including a first plug end and a second plug end, a core housing for accommodating an earphone core, and a circuit housing for accommodating a control circuit or a battery. The ear hook may be surrounded by a protective sleeve which is made of an elastic waterproof material. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The core housing may include a housing panel facing human body and a housing back panel opposite to the housing panel. When the vibration frequencies of the housing panel and the housing back panel is within a range of 2000 Hz to 3000 Hz, an absolute value of a difference between the first phase and the second phase may be less than 60 degrees. | 2022-07-14 |
20220225003 | DEVICE AND METHOD FOR DETECTING A CHANGE IN OPERATING ENVIRONMENT FOR AN ELECTRONIC APPARATUS - A detection device includes a pressure sensor, which provides a pressure signal indicative of an ambient pressure in an operating environment. An electrostatic-charge-variation sensor provides a charge-variation signal indicative of a variation of electrostatic charge associated with the operating environment, and processing circuitry is coupled to the pressure sensor and to the electrostatic-charge-variation sensor so as to receive the pressure signal and the charge-variation signal, and jointly processes the pressure signal and the charge-variation signal for detecting a variation between a first operating environment and a second operating environment for the detection device. The second operating environment is different from the first operating environment. | 2022-07-14 |
