Abstract: The present invention discloses a sound pickup device, a pet training monitor and a training monitoring method thereof. The sound pickup device comprises a single chip microcomputer, a digital silicon microphone, a wireless module and a power supply, wherein the single chip microcomputer is provided with a power supply interface and an SPI communication interface simulating a communication interface of the digital silicon microphone, and the SPI communication interface is connected with a clock pin and a data pin of the digital silicon microphone to collect single-channel audio data of the digital silicon microphone; the single-channel audio data is converted into PCM audio data by the single chip microcomputer, the single chip microcomputer is connected with an communication interface of the wireless module to transmit the PCM audio data, and an output end of the power supply is connected with the power interface of the single chip microcomputer to supply power to the single chip microcomputer.

Abstract: A stretchable watch band can include braided strands that provide a comfortable fit around the wrist of the user. The watch band can stretch and conform to the user based on the elasticity within each strand and based on the ability of the strands to move relative to each other. End sections of the watch band can include attachment elements that securely connect the watch band to a housing of the watch. The end sections can be configured to releasable connect to the housing in a manner that is reliable and easy for a user. Additionally, the watch band can provide a smooth transition from the size and/or shape of the housing to a size and/or shape of a continuous section of the watch band. Additionally, the watch band can conceal portions thereof other than the braided strands when connected to the housing of the watch.
