Embodiment 2

[0035] Embodiment 2 includes one wireless receiver 2 and one wireless transmitter 1 .

[0036] As shown in accompanying drawing 5 (B), the standby / working detection circuit 14 of wireless transmitter 1 in the present embodiment comprises state detection mercury switch 141 and transistor 143; State detection mercury switch 141 is connected described transistor 143 state detection input terminals; When the wireless transmitter 1 is at a horizontal / vertical angle, the state detection mercury switch 141 is turned off / on, and the trigger transistor 143 is turned off / on to supply power to the modulation / transmission circuit 12 from the charging and discharging control circuit 15, and the wireless transmitter 1 is controlled to be on standby / working status. In order to avoid the wearer's accidental bending and other actions, causing the angle of the wireless transmitter 1 to be in a horizontal state for a short time, which affects the normal and stable operation of the wireless tran...

Abstract

The utility model discloses a full-automatic wireless sound amplification device, belongs to the technical field of sound amplification devices, aims to solve the technical problem that the conventional wireless sound amplification device needs complex and tedious operations such as frequent startup and shutdown, charging and adjustment, and provides a full-automatic wireless sound amplification device which is convenient to use. The device comprises a wireless receiver and a wireless transmitter. The wireless transmitter comprises a microphone, a modulation / transmission circuit, a transmission antenna, a standby / working detection circuit, a charging / discharging control circuit, a storage battery and a charging input interface. The wireless receiver comprises a receiving antenna, a demodulation / power amplifier circuit, a loudspeaker, a charging output detection circuit, an AC / DC power supply, a timing control circuit and a charging output interface. The charging output interface of the wireless receiver and the charging input interface of the wireless transmitter are wired magnetic type or wireless electromagnetic induction type charging interfaces with matched mechanical and electrical parameters. The device can realize the functions of automatic startup and shutdown, automatic charging and the like, and is very convenient to use.

Description

technical field [0001] The invention relates to a sound amplifying device, in particular to a wireless sound amplifying device. Background technique [0002] The existing wireless sound amplification device does not have a unified, coordinated and overall design for the power supply, charging, and on / off functions of the wireless transmitter and wireless receiver. The power supply, charging, and on / off functions of the two are relatively independent. The operator operates the two separately, resulting in a double increase in the labor intensity of the user, especially in high-frequency, high-intensity use environments such as teachers teaching, and the wireless transmitter and wireless receiver need to be switched on and off frequently, adjusted, Plugging and unplugging, charging, etc., the actual use process of the user is very cumbersome, and the user experience is greatly reduced. Contents of the invention [0003] The purpose of the present invention is to solve the t...
