Abstract: An earphone plug with a mode switching function is presented. The earphone plug includes a terminal and a switching device. The terminal has a plurality of electrodes to transmit signals. The switching device is combined with the terminal, and is capable of switching between a first mode and a second mode, and part of the electrodes of the terminal are electrically connected together, so as to achieve mode switching to perform processing on different transmission signals.

Abstract: A multi-folded full-automatic opening-closing umbrella comprises a frame, cloth, a middle rod set, an upper nest, a lower nest, a handle, an umbrella opening/closing transformation ratio mechanism disposed in the middle rod set, and an umbrella opening/closing driving mechanism disposed in the handle and the middle rod set. The umbrella opening/closing driving mechanism drives the middle sleeve of the middle rod set to move up and down relative to the inner sleeve, and linkage opening/closing functions of the sleeves of the middle rod set and the cloth are realized at the same time.

Abstract: A noise reducing earphone includes a body, a speaker, a microphone and a signal processor. The body includes a cavity and a sound tunnel. The speaker and the microphone are both disposed in the cavity. The speaker is configured for outputting audio signals through the sound tunnel. The microphone is disposed besides the speaker and configured for receiving the audio signals in the cavity. The signal processer is electrically connected to the speaker and the microphone and configured for providing an electrical signal to the speaker so that the electrical signal is converted to an audio signal by the speaker. The microphone is configured for converting the received audio signals to an electrical signal, and sending the electrical signal to the signal processor. The signal processor is configured for outputting to the speaker an anti-phase signal with respect to the noise component defined by the signal processor in the audio signal.
