Title:
LOUDSPEAKER AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/168872
Kind Code:
A1
Abstract:
The present utility model provides a loudspeaker and a terminal device. The loudspeaker comprises a housing having an accommodating space and a sound-producing unit accommodated in the accommodating space. The sound-producing unit divides the accommodating space into a front cavity and a rear cavity. The housing is provided with a through hole in communication with the rear cavity. The loudspeaker further comprises an air-permeable isolation assembly that is fixed to the housing and covers the through hole. The air-permeable isolation assembly comprises a PET layer, an adhesive layer, and an air-permeable isolation layer stacked in sequence. The adhesive layer is sandwiched between the air-permeable isolation layer and the housing and is attached and fixed to the housing. The PET layer is attached to the side of the adhesive layer distant from the air-permeable isolation layer and accommodated in the through hole. The adhesive layer is provided with a leakage hole penetrating same, and the PET layer is correspondingly provided with a communicating hole for communicating the leakage hole with the through hole. The leakage hole is communicated with the through hole by means of the communicating hole. The air-permeable isolation layer completely covers the leakage hole. This technical solution solves the technical problem in the prior art that the loudspeaker has a relatively large thickness due to the excessive number of layers of the air-permeable isolation assembly, which is not conducive to the application to terminal devices such as mobile phones.
