Electronic equipment sounding structure

Abstract

The invention provides a sounding structure of electronic equipment, relating to the technical field of acoustics, the structure comprises a shell with a containing cavity, a sound production device located in the containing cavity and a sound outlet hole formed in the shell. A sound guide groove is communicated between the sounding device and the sound outlet hole, so that sound generated at thesounding device is conducted along the sound guide groove and is transmitted out of the shell from the sound outlet hole, the sound outlet holes comprise a first sound outlet hole for making a sound in a receiver mode and a second sound outlet hole for making a sound in a loudspeaker mode, and the second sound outlet hole is covered with a sound pressure sensitive part. The receiver is small in mode sound and small in airflow pressure, and most sound is transmitted out from the first sound outlet hole. The loudspeaker mode is large in volume and airflow pressure, sound can be transmitted out from the second sound outlet hole through the sound pressure sensitive part, the problems of airflow noise, piano sound and the like in the loudspeaker mode are solved, and meanwhile under the stereophonic application, a symmetrical sound field is more easily formed by the loudspeaker mode and a side sounding SPK on the lower portion of an electronic device (such as a mobile phone).

Description

【Technical field】 [0001] The invention relates to the technical field of acoustics, in particular to a sound output structure of electronic equipment. 【Background technique】 [0002] In prior art electronic devices, such as mobile phones, the sound output structure on the top can be used as both a receiver and a speaker, but in the speaker mode with a louder sound, there will be problems such as airflow noise and piano sound. [0003] Therefore, it is necessary to provide a sound structure that can effectively solve the problems of airflow noise and piano sound. 【Content of invention】 [0004] The purpose of the present invention is to provide a sound output structure that can effectively solve the problems of airflow noise and piano sound of electronic equipment. [0005] The technical solution of the present invention is as follows: a sound emitting structure of an electronic device, comprising a housing containing a housing cavity, a sound emitting device located in th...
