Referring to Figs. 1 and 2, a windscreen 10 is used in a portable terminal case 1. Here, the portable terminal case 1 includes all kinds of cases for portable electronic devices including portable and recordable microphones such as a mobile phone, a tablet PC, and a notebook computer. Therefore, the portable terminal case 1 has the microphone groove 2 so that the microphone can be exposed to the outside.

The windscreen (10) includes a sound shell (11) composed of at least one sound insulating member. The sound receiving portion 11 is inserted into the microphone groove 2 of the portable terminal case and covers the microphone of the portable terminal so that the microphone is not directly exposed to the outside, thereby shielding the noise. The sound receiving portion 11 may be formed by pressing at least one sound insulating member, for example, three layers of polyester may be used. This configuration of the sound pickup section 11 is illustrative, and various configurations can be applied according to the embodiment to which the present invention is applied.

As shown in FIG. 1, the sound receiving portion 11 may protrude from the center portion, and the protruded center portion may be formed to be inserted into the microphone groove 2. However, this shape is illustrative, and according to the embodiment to which the present invention is applied, the sound receiving portion 11 may have various shapes that can be inserted into the microphone groove 2.

The upper surface of the sound receiving portion 11 is pressed on the outer frame portion 12. [ Here, the upper surface of the sound receiving portion 11 is a surface opposite to a surface contacting the portable terminal, and also means a surface in contact with the case 1 of the portable terminal. The outer envelope 12 may be squeezed by heat and / or pressure. The squeezed outer frame portion 12 can be attached to the portable terminal case 1. The pressed outer frame part 12 may be attached to the portable terminal case 1 by high frequency bonding, adhesive tape, thermal bonding or ultrasonic bonding depending on the material of the portable terminal case 1, 2 by insertion into the portable terminal case 1

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 windscreen 10 according to the present invention is attached to the portable terminal case 1 rather than the portable terminal, it is possible to provide the noise shielding function of the portable terminal. In particular, by pressing the outer terminal 12, It is possible to provide the shape of the wind screen 10 suitable for the microphone groove 2 provided in the case 1 of the present invention in a simple manner.
