PURPOSE: A micro speaker is provided to improve the assembling efficiency by securely fixing a reinforcement plate and a circuit board on a fixed axis. CONSTITUTION: A fixed axis(12) protrudes downwardly through a floor side of a yoke(10). A joint(120) is formed at a certain height of the fixed axis which is downwardly protruded. A combining hole(61) that has the same shape with the cross section of the combining part is formed on a middle of a circuit board(60). A guide hole(62) is formed by extending an inner cross section of the combining hole corresponding to the both cut surface of the combining part. |
