Abstract

The invention discloses a wireless microphone. The wireless microphone comprises a power module, a wakeup module, a wakeup signal generation module and a transmission module. The wakeup signal generation module is respectively connected with the wakeup switch and the transmission module; the wakeup switch is connected with the power module; the wakeup signal generation module comprises a capacitor, a switch, a comparer and a threshold voltage module; one end of the capacitor is connected with the power module and the first input end of the comparer while the other end of the capacitor is grounded; the switch is connected in parallel with the capacitor; the second input end of the comparer is connected with the threshold voltage module; the output end of the comparer is connected with the control end of the switch; and the capacitor is connected with the transmission module. According to the wireless microphone, the wakeup switch controls the wakeup signal generation module to generate a wakeup signal of oscillation or not, and the generated wakeup signal is transmitted to a corresponding device for wakeup through the transmission module, so that the cost of additionally configuring a wakeup device is reduced greatly.

Description

technical field [0001] The invention relates to the field of voice cloud applications, in particular to a wireless microphone. Background technique [0002] With the improvement of people's material living standards, karaoke has become one of the main forms of people's recreational activities. However, conventional karaoke devices will sleep if they are not used for a certain period of time. Usually, waking up the karaoke device is performed by clicking the screen and buttons of the VOD terminal, or using a corresponding remote control. Clicking on the screen and buttons of the VOD terminal cannot satisfy the user's remote control experience, and using the remote control requires additional costs. In addition, current karaokes all use wireless microphones. If a wireless microphone with a wake-up function can be proposed, user experience can be improved and costs can be saved. Contents of the invention [0003] The technical problem to be solved by the present invention ...
