1. An integrated bone conduction sound generating device, comprising: a controller, a sound generating structure and a functional structure;
wherein the controller converts acquired sound information into a corresponding electrical signal to drive the sound generating structure;
the sound generating structure is connected with the controller, and when driven by the controller, is configured to generate a vibration signal; and
the functional structure is connected with the sound generating structure, and when touching the oral cavity or the teeth of an object to which a sound is to be transmitted, is configured to transmit, through the oral cavity or the teeth, the vibration signal to the auditory system of the object to which a sound is to be transmitted,
wherein the sound generating structure comprises an external structure and a plurality of energy conversion units accommodated in the external structure;
wherein each of the plurality of energy conversion units comprises a power receiving element connected with the external structure and a vibrating element, each of the plurality of energy conversion units passes electric energy through the power receiving element to enable the energized receiving element to generate a magnetic field, and the vibrating element is located within a range of the magnetic field generated by the power receiving element;
the controller sends the corresponding electrical signal to at least one energy conversion unit with a highest degree of matching between a resonance peak frequency of the vibrating element and a frequency band characteristic of the sound information in the plurality of energy conversion units, so that it is responsible for realizing a sound effect of a high frequency band and the other energy conversion units in the plurality of energy conversion units are responsible for realizing a sound effect of a low frequency band.
