the circuit housing includes two sub-housings that are fastened to each other, and
the housing sheath covers a joint seam of the two sub-housings.
7. The speaker device of claim 1 , wherein
a stopping block is disposed on an inner side wall of the socket; and
the socket includes:
an insertion unit, at least a portion of the insertion unit being inserted into the socket and abutted against an outer surface of the stopping block; and
two elastic hooks disposed on a side of the insertion unit facing an inside of the core housing, the two elastic hooks getting close to each other under an action of an external force and the stopping block, and after passing the stopping block, the two elastic hooks elastically returning to be clamped on the inner surface of the stopping block to plug and fix the core housing and the plug end.
8. The speaker device of claim 7 , wherein
at least a portion of the insertion unit is inserted into the socket, the other portion of the insertion unit not inserted into the socket has a stepped structure and form a second annular table, and the second annular table is disposed apart from an outer end surface of the core housing; and
the ear hook includes a protective sleeve disposed on a periphery of the elastic metal wire and the plug end, the protective sleeve extends to a side of the second annular table facing the outer end surface of the core housing, and the protective sleeve elastically abuts against the core housing when the core housing and the plug end are plugged and fixed.
9. The speaker device of claim 1 , wherein the earphone core at least includes a composite vibration device constituted by a vibration plate and a second vibration conductive plate, the composite vibration device generating the two resonance peaks.
10. The speaker device of claim 9 , wherein
the earphone core further includes at least one voice coil and at least one magnetic circuit assembly; and
the at least one voice coil is physically connected to the vibration plate, and the at least one magnetic circuit assembly is physically connected to the second vibration conductive plate.
11. The speaker device of claim 9 , wherein a stiffness coefficient of the vibration plate is greater than a stiffness coefficient of the second vibration conductive plate.
12. The speaker device of claim 9 , wherein the earphone core further includes a first vibration conductive plate, wherein
the first vibration conductive plate is physically connected to the composite vibration component;
the first vibration conductive plate is physically connected to the core housing; and
the first vibration conductive plate generates another resonance peak.
13. The speaker device of claim 12 , wherein the two resonance peaks are within a frequency range perceivable by human ears.
