The invention relates to an extended-type loudspeaker. The extended-type loudspeaker has a delicate structure and a good using effect and can be used for simple and effective function extension. The extended-type loudspeaker comprises a frame-shaped basin stand, a magnetic cover, a magnetic-circuit system, a vibrating system and a pair of pins, wherein the pair of pins are connected onto a pair of top corners of the basin stand; each pin comprises a body, an extending sheet, a pressure-welding curved surface and a welding sheet; an arc-shaped buffer slot which is used for accommodating the connecting part of the pressure-welding curved surface and the body is formed in the top corner of the basin stand. According to the extended-type loudspeaker, after the loudspeaker is installed, the pressure-welding curved surface can be effectively abutted against a main board of a mobile phone, and an electrical signal is sequentially transferred onto a voice coil in the vibrating system through the body and the welding sheet after the loudspeaker is electrified; the extending sheet is also additionally arranged at one side of the body in the loudspeaker, so that other capacitance modules or resistance modules can be connected in series and in parallel to the outside of the loudspeaker through the extending sheets when the loudspeaker is used. Thus, the function (module) extension of the loudspeaker can be effectively carried out on the basis that only one pair of pins are used in the loudspeaker, so that the loudspeaker has the advantages of wider usage range and better using effect.
