Abstract

The invention relates to a planar loudspeaker device which comprises an upper casing, a lower casing, a planar loudspeaker single body, a conductive electrode group and more than one locking piece. The upper casing is provided with a first positioning portion, and the lower casing is arranged under the upper casing and provided with a second positioning portion. The planar loudspeaker single body comprises more than one hole electrode and a vibrating diaphragm. Each hole electrode is provided with a plurality of holes, and the hole electrodes and the vibrating diaphragm are clamped to form a plurality of air cavities. The conductive electrode group is connected with the planar loudspeaker single body and used for providing a power supply signal for transmitting sound. The locking piece is used for fixing the upper casing and the lower casing and clamping the planar loudspeaker single body and the conductive electrode group.

Description

technical field [0001] The invention relates to a plane speaker device, in particular to a bendable plane speaker device. Background technique [0002] Among the human sensory responses, hearing and vision are the most direct. For a long time, scientists have been committed to developing related components or system technologies to produce products with better visual or auditory performance to meet consumer needs. The currently known types of loudspeakers are mainly divided into direct radiation type and indirect radiation type, and can be classified into moving coil type, piezoelectric type and electrostatic type according to the driving method. Among them, dynamic speakers are the most widely used products at present. [0003] However, due to the shortcomings of the inherent structure of the dynamic speaker, the volume cannot be flattened. Therefore, in the face of 3C products that emphasize lightness, lightness and compactness, and in response to the flattening trend o...
