1. An acoustic output device, comprising:
a first piezoelectric element configured to generate vibrations based on an audio signal;
a fixing structure configured to place the acoustic output device near a user's ear without blocking the user's ear canal, an end of the fixing structure being connected to one end of the first piezoelectric element; and
a vibration transmission component including an ear hook and an output assembly, one end of the ear hook being connected to an end of the first piezoelectric element away from the fixing structure, the other end of the ear hook being connected to the output assembly, the output assembly receiving the vibrations of the first piezoelectric element through the ear hook and outputting sound, and a frequency response curve of the sound having at least two resonant peaks.
