Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides an earphone with auxiliary vibration, combine shown in fig. 1-6, including a hollow casing 10 for holding acoustic component, casing 10 comprises front chamber 13 and rear chamber 14, the both ends of casing 10 are equipped with metal conduit 11 and wire connection pipe 12 respectively, metal conduit 11 runs through in casing 10 and communicates with each other rather than inside, metal conduit 11 is used for inserting the inside conduction sound of people's ear, wire connection pipe 12 is used for inserting the connecting wire of earphone and links to each other rather than inside acoustic component, and specifically speaking, metal conduit 11 sets up on front chamber 13, wire connection pipe 12 sets up on rear chamber 14, sound production unit 20 is fixed with transversely in the inside of front chamber 13, and sound production unit 20 is single-action circle formula, and is equipped with annular boss 15 on the front chamber 13 inner wall be equipped with auxiliary vibration device 30 between sound production unit 20 and metal conduit 11, the auxiliary vibration device 30 is disposed on the boss 15.

Specifically, as shown in fig. 1-3, for the first embodiment provided by the present invention, here the auxiliary vibration device 30 is a metal vibration plate, the metal vibration plate includes an outer frame 31 and an elastic plate 32 suspended in the outer frame 31, the outer frame 31 is fixed on the boss 15, the outer frame 31 and the elastic plate 32 are connected to each other through a plurality of connecting arms 33, a plurality of over-current channels are formed between the connecting arms 33.
