Description

Application structure and method of the internal speaker {The application of invisible speaker and the method for fabricating the same}

The present invention relates to an application structure and method of a built-in speaker having an electric appliance main body, a transparent element, and a first transducer, which can greatly improve the vocalization effect of a general speaker.

Conventional flat speakers generally occupy one entity space, thereby sounding at the location where it is located. Fig. 6 is a patent application of PCT Publication WO 97/09854, which is a perspective view in which a prior art flat speaker is applied to a notebook computer. According to FIG. 6, two planar speakers 10, 11 having acoustic radiators 12 in respective uniform distribution modes and a transducer 13 are provided. These two flat speakers 10 and 11 are connected to both sides of the liquid crystal display screen 15 of the notebook computer 14 to achieve sound vocal effects. In this application, the flat speakers must be folded to shrink the screen. (15) Must be deployed at excretion positions on both sides. In addition, since the space occupied by these two planar speakers 10 and 11 is quite large, the notebook computer 14 cannot be handled with sufficient convenience, and thus it is arranged to meet the demand for modern compactness and the demand for smooth and smooth work. do.

7 is a perspective view showing a portable personal electronic organizer 20 having a calculator and a dictionary function and a speaker thereof. Since the speaker 21 and the display screen 22 are provided separately and independently, the spoken voice is not clear, and therefore, if a relatively large speaker 21 is to be used, it occupies a considerable amount of space. Since the openable cellular phone 30 of FIG. 8 also takes the design method of separating the hydration speaker 31 and the display screen 32, the user must hear the other party's voice by bringing the hydration speaker 31 close to the ear. have. In addition, in the mobile phone 30 having the function of the wireless communication agreement, the voice of the sign language speaker 31 is heard only when the mobile phone is placed close to the ear while watching and recording the characters on the display screen 32. There is a problem that you must make a round trip.

Fig. 9 is a diagram showing a patent application of PCT Publication WO 97/09852. In the visual indicator 40 according to the drawing, there are two uniformly distributed mode acoustic radiators 42 and a casing 41 to which a transducer is attached, and the acoustic radiators 42 vibrate air to generate sound waves. Since the sound waves vibrate the casing 41 again, the first voice can be transmitted to the user's ear, which wastes relatively power.

Similarly, in the vending machine 50 of the PCT publication WO 97/09698 patent application shown in FIG. 10, the transducer 51 vibrates the uniform distribution mode acoustic radiator 52 first, so that the acoustic wave vibration plastic cover 53 is provided. Has the drawback of indirectly transmitting sound waves. In addition, the transducer 62 provided on the chair back of the seat 60 of the seat 60 of the engine compartment of PCT Publication No. 97/09844 in the patent application of Fig. 11 first vibrates the uniform distribution mode acoustic radiator 72, so that the sound waves are on the chair back. The leather grove 64 of 61 is vibrated. In addition, Figure 12 shows the bulletin board 70 of the PCT publication WO 97/09848 patent application, the transducer 71 installed there first vibrates the uniform distribution mode acoustic radiator 72, so that the sound waves are plastic cover plate ( Vibrate 73). As such, since they do not all directly generate sound waves, they are not the best way to operate power.

Therefore, as a result of the present inventor's research on how to improve the shortcomings of using the speaker and the display screen separately, the internal speaker effectively solves the problems of the prior art and makes the sound effect of the speaker more clear. Has achieved the application structure and method thereof.

That is, the main object of the present invention is to provide an application structure and method of the built-in speaker by combining the transducer and the transparent element, effectively reducing the space occupied by the speaker of the notebook computer.

Another object of the present invention is to provide an application structure and method of a built-in speaker that effectively improves the speaker's speech effect by vibrating the transparent element of the electrical appliance directly to the transducer.

It is still another object of the present invention to provide an application structure and method of a built-in speaker that can simultaneously view and sign a user as a mobile phone by using a transparent element as a speaker.
