Abstract
A loudspeaker module comprises an outer casing in which a vibration system and a magnetic circuit system are received. The magnetic circuit system comprises a basin-like stand fixed on the outer casing. The outer casing comprises a second casing provided with a rear sound exit hole that transversely runs through the inner side surface and the outer side surface of the second casing at the position corresponding to the outer side surface of the sidewall of the basin-like stand. The rear sound exit hole is communicated with an inner cavity of the module and an inner cavity of the electronic terminal. A chamfered plane is disposed at an upper end of the sidewall of the basin-like stand, and on a side of the sidewall of the basin-like stand. A sound emitting channel is formed between the chamfered plane and the inner side surface of the second casing.
