Title:
ELECTROACOUSTIC DEVICE, MANUFACTURING METHOD THEREFOR, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/047749
Kind Code:
A1
Abstract:
Disclosed are an electroacoustic device, a manufacturing method therefor, and a mobile terminal. The electroacoustic device is provided with an outer frame body, the outer frame body is provided with a sealed cavity and a jack in communication with the sealed cavity; a partition, a part of the partition being arranged within the sealed cavity, the other part of the partition being arranged within the jack, thus allowing the partition to partition the sealed cavity to form a first cavity and a second cavity; an electroacoustic component, the electroacoustic being arranged within the first cavity, and the electroacoustic component being used for emitting sound waves; and a sound absorbing medium, the sound absorbing medium being arranged within the second cavity, and the sound absorbing medium being used for absorbing sound waves passing through the partition. Because the partition is slidably connected to the outer frame body, during an assembly process, the sound absorbing medium can be filled into the sealed cavity first, then the partition can be employed to block off the sound absorbing medium so as to form the second cavity filled with the sound absorbing medium and the first cavity accommodating the electroacoustic component, thus allowing the sound absorbing medium to be arranged within the second cavity as much as possible, greatly increasing sound absorbing effects, reducing noise, and enhancing sound quality.
