Loudspeaker and assembly method therefor, vibration mechanism, and loudspeaker device

A loudspeaker, comprising:

• a magnetic circuit system;
• a paper cone having a paper cone outer side;
• a suspension element having a suspension element inner side and a suspension element outer side;
• a voice coil having a voice coil lower end and a voice coil upper end;
• and
• a frame having a frame lower end and a frame upper end, wherein said magnetic circuit system is mounted to said frame lower end of said frame, wherein said suspension element inner side of said suspension element is extended inward to be connected to said paper cone outer side of said paper cone, wherein said suspension element outer side of said suspension element is extended outward to be connected to said frame upper end of said frame, wherein said voice coil upper end is connected to is connected to said paper cone to define an induced position of said paper cone, wherein said voice coil lower end of said voice coil and said magnetic circuit system are magnetically coupled with each other, wherein said induced position of said paper cone deviates from a central axis of said loudspeaker.

A loudspeaker device, comprising a cabinet and a loudspeaker, wherein said cabinet comprises a front baffle, wherein said loudspeaker is mounted to said front baffle of said cabinet, wherein said loudspeaker comprises:

• a magnetic circuit system;
• a paper cone having a paper cone outer side;
• a suspension element having a suspension element inner side and a suspension element outer side;
• a voice coil having a voice coil lower end and a voice coil upper end;
• and
• a frame having a frame lower end and a frame upper end, wherein said magnetic circuit system is mounted to said frame lower end of said frame, wherein said suspension element inner side of said suspension element is extended inward to be connected to said paper cone outer side of said paper cone, wherein said suspension element outer side of said suspension element is extended outward to be connected to said frame upper end of said frame, wherein said voice coil upper end is connected to said paper cone to define an induced position of said paper cone, wherein said voice coil lower end of said voice coil and said magnetic circuit system connect with each other in such a manner that said voice coil lower end of said voice coil and said magnetic circuit system magnetically interact with each other, wherein said induced position of said paper cone deviate to a central axis of said loudspeaker.

A method for assembling a loudspeaker, comprising the following steps:

• (a) installing a magnetic circuit system to a magnetic circuit mounting ring of a lower end frame in such a manner that a central axis of said magnetic circuit system deviates from a central axis of an engaging ring of said lower end frame;
• (b) allowing a suspension element inner side and a suspension element outer side of a suspension element to be connected to a paper cone outer side of a paper cone and a retaining ring of an upper end frame respectively;
• and
• (c) installing said upper end frame to said lower end frame in such a manner that a central axis of said retaining ring and a central axis of said engaging ring coincide with each other, so as to allow a voice coil which is connected to an induced position of said paper cone to be extended toward said magnetic circuit system and is magnetically coupled to said magnetic circuit system, and said induced position of said paper cone is deviated from a central axis of said loudspeaker, so as to assemble said loudspeaker.
