Abstract: The broken string energy absorbing device includes a fixing mechanism and a cushioning and energy absorbing mechanism. The fixing mechanism is configured to fix the broken string energy absorbing device to a neck of the stringed instrument. The cushioning and energy absorbing mechanism is configured to absorb and weaken the energy when a string of the stringed instrument is broken. The present invention can sufficiently protect the user from not being exploded by the broken string when tuning the strings, which effectively ensures the safety of the user when tuning. The user no longer has the psychological burden of worrying about whether the string will be broken, so that the user can safely tune the strings, which provides good user experience and is favorable for the user to further learn the instrument.
