Abstract
Description
BACKGROUND OF THE
BACKGROUND ART [0002] As a case of recording a moving image or a voice using a camera or a mobile terminal increases, a wind screen is used as a device for more accurately recording sound without noise.
In general, a windscreen is implemented as a simple planar sound-insulating portion and is attached to a microphone of a camera or a portable terminal. In this case, the sound-absorbing effect is lowered due to a low adhesion to the camera, and the shape directly attached to the portable terminal may not be preferred by the user in the appearance of the portable terminal, and if it is attached inside the portable terminal, There is a problem.
In addition, since such a windscreen is exposed to the outside, the windscreen is constantly subjected to irritation from the outside, and thus damage such as abrasion of the windscreen is caused, thereby reducing noise shielding performance and reducing the life span.
Therefore, a windscreen capable of effectively shielding noise and providing improved durability is required.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a windscreen having improved durability while effectively shielding noise from a camera, a portable terminal, and the like.
A windscreen used in a portable terminal case having a microphone groove according to an embodiment of the present invention is disclosed. The windscreen may include at least one sound insulating member and a sound insulating portion inserted into the microphone groove. The upper surface of the sound insulating portion may have a squeezed outer peripheral portion.
Preferably, the outer frame is attached to the case of the portable terminal.
Preferably, the outer frame is attached to the portable terminal case by at least one of high frequency bonding, adhesive tape, thermal bonding, and ultrasonic bonding.
In accordance with another embodiment of the present invention, a windscreen is disclosed. The windscreen may include a sound-insulating portion formed of at least one sound-insulating member, and the upper surface of the sound-shielding portion may have a squeezed outer frame portion.
Preferably, it further comprises a double-sided tape adhered to a lower surface of the sound-receiving portion.
Preferably, the double-sided tape is adhered to a region of the lower surface of the lower shell corresponding to the outer frame, in order to secure adhesion between the lower shell and the double-sided tape.
According to the present invention, the windscreen is attached to the case of the portable terminal rather than the portable terminal, so that the noise shielding function of the portable terminal can be provided in a simple manner.
According to the present invention, it is possible to provide a windscreen having a shape suitable for a microphone groove provided in a case of a portable terminal by manufacturing a windscreen by squeezing the outer frame of the sounder.
According to the present invention, it is possible to firmly fix the shape of the edge of the windscreen and to provide improved durability against external stimuli by squeezing the outer frame of the sound shell.
According to the present invention, by pressing the outer frame portion of the sound insertion portion, the area corresponding to the compressed outer frame portion of the lower surface of the sound insertion portion can be realized as a relatively flat surface as compared with the area excluding the corresponding area, By attaching the double-sided tape to the surface, it is possible to firmly adhere the double-sided tape to the sound-receiving portion.
BRIEF DESCRIPTION OF THE DRAWINGS A brief description of each drawing is provided to more fully understand the drawings recited in the description of the invention.
1 is a view of a windscreen according to an embodiment of the present invention.
2 is a side view of the windscreen according to Fig.
3 is a view showing a sound shielding effect by the wind screen according to FIG.
4 is a view showing a wind screen according to another embodiment of the present invention.
5 is a view showing a noise shielding effect by the wind screen according to FIG.
Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, embodiments of the present invention will be described below, but the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.
Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.
1 is a view of a windscreen according to an embodiment of the present invention, and Fig. 2 is a side view of a windscreen according to Fig. 1. Fig.
Referring to Figs. 1 and 2, a
The windscreen (10) includes a sound shell (11) composed of at least one sound insulating member. The
As shown in FIG. 1, the
The upper surface of the
In general, since a microphone hole is located on a side surface of a portable terminal, it is not easy to attach a wind screen to the portable terminal. Thus, the recording function of the portable terminal has accompanied various noise problems. However, since the
3 is a view showing a sound shielding effect by the wind screen according to FIG.
As shown in FIG. 3, the waveform (a) of the sound recorded through the portable terminal mounted on the portable terminal case having the wind screen is the waveform (b) of the sound recorded through the portable terminal which does not use the wind screen, And less noise. Therefore, by using the windscreen according to the present invention, a higher sound insulation effect can be obtained.
4 is a view showing a wind screen according to another embodiment of the present invention.
As shown in Fig. 4 (a), the
The

The
5 is a view showing a noise shielding effect by the wind screen according to FIG.
As shown in FIG. 5, the waveform (a) of the sound recorded through the camera equipped with the windscreen contains less noise than the waveform (b) of the sound recorded through the camera without the windscreen. Therefore, by using the windscreen according to the present invention, noise can be shielded more efficiently.
As described above, an optimal embodiment has been disclosed in the drawings and specification. Although specific terms have been employed herein, they are used for purposes of illustration only and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
