Smart wearable glasses

Smart wearable glasses, comprising:

• a frame;
• temples extending from opposite sides of the frame, and being of hollow structure;
• a vibration unit fixed in the temples, comprising:
• a bone conduction contact portion at least partially exposed in the temples, configured to contact user's skull and transmit a vibration acoustic signal generated by the vibration unit to a user by means of bone conduction;
• the temples comprise a first body extending from the frame and a first cover fixedly covered on the first body, enclosing a first acoustic cavity together with the first body;
• and
• a sounding unit fixed in the temples, wherein the sounding unit is fixedly accommodated in the first acoustic cavity, the sounding unit comprising:
• a housing having an accommodation space and an inverted channel, the housing comprises:
• a bottom wall fixedly accommodated in the first acoustic cavity;
• a side wall extending from a periphery of the bottom wall to the first acoustic cavity in a curved manner;
• a top cover covered on the side wall;
• a support wall extending from the bottom wall toward the top cover;
• and an inverted tube cover;
• wherein the bottom wall, the side wall, the support wall, and the inverted tube cover together enclose the inverted channel;
• the bottom wall, the side wall, the support wall, and the top cover together enclose the accommodation space;
• wherein a first sound outlet hole, a first inverted hole, and a first leakage hole are arranged at intervals and through the housing;
• the first sound outlet hole, the first inverted hole, and the first leakage hole are arranged through the side wall, respectively;
• a sounding driver for emitting acoustic signal fixed in the accommodation space, and separating the accommodation space into a front cavity and a coupled rear cavity;
• the front cavity being connected to the outside world of the temples through the first sound outlet hole;
• and
• an inverted tube arranged in the inverted channel, connected to the outside world of the temples through the inverted channel and the first inverted hole in sequence, wherein the coupled rear cavity is connected to the outside world of the temples through the first leakage hole and the inverted tube;
• wherein
• a phase of an acoustic wave emitted by the sounding unit through the first sound outlet hole is opposite to a phase of an acoustic wave emitted by the sounding unit through the first leakage hole;
• a size of the inverted tube is calculated based on a volume of the front cavity, a volume of the coupled rear cavity, and a Thiele-Small (TS) parameter of the sounding driver.
