Implementing an Electrostatic Loudspeaker in a Laptop Computer

Disclosed is a method that places an electrostatic loudspeaker on the front surface of a laptop display. Benefits include improved sound quality.

Background

Currently, laptop loudspeakers are integrated into the computer’s hand/rest area. Therefore, either the user’s hands or lap tend to muffle the sound.

General Description

The disclosed method integrates an electrostatic loudspeaker into a laptop computer screen. Figure 1 shows an electrostatic material placed on the front glass of the laptop display. A dielectric spacer separates the electrostatic material from the thin diaphragm. A second spacer with an electrostatic-coated surface is placed on the other side of the diaphragm, forming a complete electrostatic loudspeaker.

Although true stereo separation may not be achieved on a laptop due to the short screen width, the screen can be divided into two speaker halves; each half emits either the left or right portion of the stereo signal.

Advantages

The disclosed method focuses sound directly at the user’s head, improving the clarity of the sound and avoiding the muffling problems associated with the current state of the art.
