| description | The present application relates to a mobile terminal, comprising: a housing provided with an accommodating cavity and sound outlets; and a loudspeaker assembly that is provided in the accommodating cavity and outputs sound by means of the sound outlets. The loudspeaker assembly comprises a loudspeaker and a dustproof net; the dustproof net is fixed on the housing and is located between the loudspeaker and the housing; the loudspeaker comprises a vibration diaphragm used for vibrating to generate sound; the proportion of the area of the sound outlets to the effective area of the vibration diaphragm is not greater than 15%; the net-shaped area of the dustproof net is greater than the area of the sound outlets; the dustproof net, the housing, and the loudspeaker all are arranged at intervals. The mobile terminal of the present application increases the net-shaped area of the dustproof net, so that sound is propagated to the sound outlets by means of a gap between the dustproof net and the housing, thereby increasing the air-permeable area of the dustproof net and reducing a thermal viscous effect, and thus reducing the attenuation effect of the dustproof net on sound, increasing a signal-to-noise ratio, and avoiding the condition that abnormal sound is generated because the dustproof net vibrates and collides with the housing and the loudspeaker. |
