Terminal protection shell and audio playing system

Abstract

The invention discloses a terminal protection shell and an audio playing system. The audio playing system comprises the terminal protection shell and a terminal installed on the terminal protection shell. The terminal protection shell is provided with the piezoelectric loudspeaker, and the piezoelectric loudspeaker can make a sound under the control of the terminal, so that the piezoelectric loudspeaker can make a sound together with the loudspeaker of the terminal, and the audio playing system is enabled to have a relatively large loudspeaker volume.

Description

technical field [0001] The present application relates to the field of audio technology, and in particular, to a terminal protective shell and an audio playback system. Background technique [0002] As the user's demand for the volume of the external sound from the terminal (such as mobile phone, tablet, etc.) increases, the amplitude of the terminal's speaker (also called the external speaker) continues to increase. At present, the amplitude of some speakers has reached 0.4 mm. to 0.5 mm or more, and an increase in the amplitude of the horn results in a corresponding increase in the size of the horn. However, since the current terminals are pursuing thinness and lightness, the size of the speakers installed inside the terminals is strictly limited, the amplitude of the speakers is difficult to greatly increase, and the volume of the speakers is limited, which makes it difficult to increase the external volume of the terminals. SUMMARY OF THE INVENTION [0003] The purpos...

Problems solved by technology

[0002] With the increasing demand of users for the volume of external sound from terminals (such as mobile phones, tablets, etc.), the amplitude of terminal speakers (also called external speakers) is increasing. At present, the amplitude of some speakers has reached 0.4 mm. to 0.5 mm, or even larger, and the increase in the amplitude of the horn will lead to a corresponding increase in the size of the horn

However, since the current terminals are pursuing thinner and lighter, the size of the speaker installed inside the terminal is strictly limited, the amplitude of the speaker is difficult to increase significantly, and the volume of the speaker is limited, which makes it difficult to increase the volume of the terminal.
