Description

How to install an electrostatic speaker on a laptop

The present invention mainly relates to a laptop computer, and in particular to a laptop computer equipped with an electrostatic speaker, and a method for installing the electrostatic speaker in the laptop computer.

Speakers, also known as loudspeakers, are very common sound players. They are acoustic devices used to increase the efficiency of sound transmission. They convert electrical signals into mechanical vibrations of the diaphragm, which in turn causes changes in the density of the surrounding air to produce sound.

Traditional laptop computers usually use a traditional box-type speaker design. However, the volume of the traditional box-type speaker must occupy a lot of internal space of the traditional laptop computer, which will affect the thin design of the traditional laptop computer.

The first stator and the second stator are electrically connected to a transformer respectively. The speaker module also has a support structure disposed between the keyboard and the bottom shell, and the electrostatic diaphragm is coupled to the support structure.

In some embodiments, the support structure is made of an insulating material.

The present invention relates to a notebook computer with an electrostatic speaker, comprising: a first body 1, a second body 2 and a speaker module 3, wherein the speaker module 3 is disposed on one of the first body 1 and the second body 2.

In the present invention, the first body 1 is used to output images and display graphical interfaces, the second body 2 is a host with logical computing and data access capabilities, and the second body 2 is connected to the first body 1.

Please refer to Figures 1 and 2, which are respectively a three-dimensional exploded view and a three-dimensional assembly view of the first embodiment of the present invention having an electrostatic speaker. In this embodiment, the speaker module 3 is arranged on the first body 1. Specifically, the first body 1 includes a screen cover 11 and a screen frame 12, and serves as a first stator and a second stator of the speaker module 3, respectively. The first stator and the second stator are electrically connected to a transformer to convert their respective polarities. Among them, the screen cover 11 and the screen frame 12 are both made of metal material.

The speaker module 3 includes a supporting structure 31 and an electrostatic diaphragm 32, wherein the supporting structure 31 is disposed between the first stator and the second stator. In this embodiment, the supporting structure 31 is disposed between the screen cover 11 and the screen frame 12, and the supporting structure 31 is made of an insulating material. The electrostatic diaphragm 32 is coupled to the supporting structure 31 and electrically connected to a static generator for providing a positive electrostatic voltage to change the voltage polarity of the first stator and the second stator.

The principle of the speaker module 3 is: like repels like, and opposites attract. Specifically, when the voltage of the first stator is negative, the voltage of the second stator is positive. At this time, the electrostatic diaphragm 32 will be attracted toward the first stator. Then, the polarity of the first stator and the second stator is swapped, so that the voltage of the first stator is converted to positive and the voltage of the second stator is converted to negative. At this time, the electrostatic diaphragm 32 will be attracted toward the second stator. In this way, the electrostatic diaphragm 32 is displaced, thereby pushing the air to generate sound waves.

Please refer to Figures 3 and 4, which are respectively a three-dimensional exploded view and a three-dimensional assembly view of the second embodiment of the present invention having an electrostatic speaker.

The first stator and the second stator are electrically connected to a transformer respectively to convert their respective polarities. The keyboard 21 and the bottom shell 22 are both made of metal. On the other hand, in this embodiment, the support structure 31 is disposed between the keyboard 21 and the bottom shell 22.

In the above embodiment, the second body 2 of the laptop computer with an electrostatic speaker of the present invention may also have a heat dissipation module, which is vertically overlapped with the electrostatic generator.

In the above-mentioned embodiment, the laptop computer with an electrostatic speaker of the present invention may also have a leakage protection device connected to the electrostatic generator.

In this embodiment, the transformer is a center-tapped transformer to provide a return path for the polarized voltage.
