description The utility model provides a clipping reminding circuit and electronic equipment, and relates to the technical field of sound amplification, the clipping reminding circuit comprises a comparison circuit and a reminding circuit; according to the utility model, the magnitude of the power amplifier signal is compared with the magnitude of the main line voltage signal, so that whether signal clipping exists or not is judged, and when the power amplifier signal clipping occurs in the circuit, a user is reminded through the reminding circuit, so that the technical problems of clipping effect and influence on sound amplification effect caused by over-high current signal in the loudspeaker are avoided. 本实用新型提供了一种削波提醒电路及电子设备，涉及扩音技术领域，所述削波提醒电路包括：比较电路与提醒电路；本实用新型通过比较功放信号与主线电压信号的大小，从而判断是否存在信号削波的情况，并在电路出现功放信号削波的情况时，通过提醒电路进行提醒用户，避免了扬声器中电流信号过高导致的削波效果，影响声音放大效果的技术问题。
