1. A transmitter for musical instrument which transmits a sound signal emitted from a musical instrument to an outside using a battery arranged inside a main body of the transmitter, wherein
the transmitter for musical instrument has a first mode and a second mode in which power consumption of the battery is smaller than the first mode, and
the transmitter for musical instrument comprises:
a detection part for detecting an acceleration of the main body;
a switching part for transitioning to the second mode when a detection value of the detection part shows a value within a predetermined range during a predetermined time in the first mode;
a release part for releasing the second mode to transition to the first mode when the detection value of the detection part exceeds a release threshold value in the second mode; and
a release threshold value setting part for setting the release threshold value based on the detection value of the detection part at a time of transition from the first mode to the second mode;
wherein the detection part comprises a three-axis acceleration sensor, and
the release threshold value setting part sets the release threshold value based on a second greatest detection value and a third greatest detection value among detection values of the three-axis acceleration sensor.
