Abstract
The present disclosure provides a speaker, including a housing and a vibration unit and a magnetic circuit unit that are received in the housing. The magnetic circuit unit includes a magnetic frame, the magnetic frame comprising a bottom wall and a sidewall extending from the bottom wall while being bent towards the housing. A positioning portion protruding outwardly is provided on the sidewall of the magnetic frame, and the positioning portion abuts against the housing. The speaker of the present disclosure can achieve the positioning of the magnetic frame using the positioning portion provided on the sidewall of the magnetic frame during the assembling, and it is unnecessary to sacrifice the flanging length of the magnetic frame, so that the flanging of the magnetic frame can be maximized, thereby improving the performance of the speaker.
