Horn type micro loudspeaker and terminal equipment

Abstract

The invention discloses a horn type micro loudspeaker, which is applied to terminal equipment. The horn type micro loudspeaker comprises a micro loudspeaker. The horn type micro loudspeaker further comprises a horn which is connected with the micro loudspeaker. An upper top surface and a lower bottom surface of the horn on a thickness direction of the terminal equipment are planes; the upper top surface is parallel with an upper shell surface of the terminal equipment while the lower bottom surface is parallel with a lower shell surface of the terminal equipment. On a direction vertical to the thickness direction of the terminal equipment and a length direction of the horn, the horn is extended from a horn port to a horn waiting port. The above technical proposal of the horn type micro loudspeaker combines the micro loudspeaker and the horn under the premise that the thickness of the terminal equipment is relative thin, thereby achieving goals of low resonance frequency F0 and large loudness.

Description

technical field [0001] The invention relates to the technical field of design of micro-speakers in terminal equipment, in particular to a horn-type micro-speaker and terminal equipment. Background technique [0002] Nowadays, the resonant frequency F0 and loudness of micro-speakers (speakers) in terminal equipment such as mobile phones and tablets are important indicators for evaluating the sound quality of terminal equipment, and designers have higher and higher performance requirements for speakers: smaller size, more Thinner, lower resonance frequency F0, louder. [0003] In the prior art, in the design of a large loudspeaker, a horn design is usually used to increase the loudness, and the design of the horn is not limited by space and can be extended in multiple directions. However, for micro-speakers, due to the restriction of the thickness of the terminal equipment, these indicators of micro-speakers are contradictory, that is, when the size becomes smaller and thinne...

AI Technical Summary

Problems solved by technology

However, for micro-speakers, due to the restriction of the thickness of the terminal equipment, these indicators of micro-speakers are contradictory, that is, when the size becomes smaller and thinner, there is little room for improvement in loudness, and the resonant frequency F0 is also small. It is difficult to drop down (loudness is not enough, F0 is too high), and it is impossible to make the resonant frequency F0 of the micro-speaker low and the loudness large, which requires special design or application to comprehensively improve the indicators required by the micro-speaker
