Abstract

The invention discloses a transparent horn and a display module integrating the transparent horn. The transparent horn is suitable to be arranged on a display panel and comprises a transparent diaphragm, transparent electrode plates and spacing materials, wherein each transparent electrode plate is provided with a plurality of holes; the display panel comprises a plurality of pixels which transmit an optical signal; and after the optical signal passes through the transparent horn, the superposition fringe spacial period of the optical signal is less than 600 mu m. When the transparent horn is arranged on the display panel, a user can watch pictures on the display panel through the transparent horn and is not interfered by superposition fringes.

Description

technical field [0001] The invention relates to a speaker and a display device with the speaker, in particular to a transparent speaker and a display device integrating the transparent speaker. Background technique [0002] Generally speaking, when the size of the speaker is larger, the speaker will have better sound quality. However, for a notebook computer or a handheld mobile device, the space available for accommodating the speaker is limited due to the notebook computer or the handheld mobile device. Therefore, these speakers built into notebook computers or handheld mobile devices are not easy to have good sound quality. On the other hand, in a notebook computer or a handheld mobile device, the space of the display panel occupies a large proportion. If a transparent speaker that can be placed in front of the display panel can be developed, the space of a notebook computer or a handheld mobile device can be utilized more effectively. In other words, if the notebook c...
