Abstract

The invention provides mobile terminal equipment, which comprises an equipment main body, a loudspeaker and a volume variable sound cavity. The loudspeaker is fixedly arranged in the volume variable sound cavity and is electrically connected with the equipment main body; and the volume variable sound cavity is fixedly arranged on the equipment main body. The loudspeaker is arranged in the volume variable sound cavity, and the volume of the volume variable sound cavity can be enlarged only by changing the volume of the volume variable sound cavity so as to easily enlarge the volume of the sound cavity in the mobile terminal equipment, improve the low frequency effect of sound and improve the sound quality of the mobile terminal equipment.

Description

technical field

[0001] The present invention relates to the field of electronic technology, in particular to a mobile terminal device. Background technique

[0002] Currently, mobile terminal devices (such as mobile phones, netbooks or MP3 players) are widely used by users because of their portability. The mobile terminal device is usually equipped with a sound box, and the sound box is arranged in the shell of the mobile terminal device, so that the audio signal sent by the mobile terminal device can be played through the speaker in the sound box. Due to the gradual miniaturization of mobile terminal equipment, the volume of the sound cavity in the speaker is gradually reduced, so that the low-frequency components in the sound emitted by the speaker on the mobile terminal device are insufficient, the sound is monotonous and weak, and the subjective experience of the human ear is not good. , resulting in poor sound quality of the mobile terminal equipment in the prior art. ...
