Its kneading surface is superior to the traditional TV AC3 audio. /趄一, also provides three-dimensional, Dolby In recent years, the continuous advancement of technology, light, thin, short, small direction / Dou Xizi products are easy to carry out. Therefore, the consideration is to facilitate the user to operate the digital TV, so that the size of the TV is reduced to portable. When portable digital = 1? Take out or install in the car to connect an external antenna, you must watch the digital TV in the digital TV car or outdoor. This antenna can be received by the user. When it is relatively wide, the furnace J is made to have a larger size of the 200838035 in order to make the volume of the digital antenna of the digital television, such as the certificate No. M277i2 of the national patent publication (as shown in the first figure ^, the fourth (four) No. (as shown in the second figure), (4) (10) (such as the Ang II map) and No. 286443 (as shown in the fourth figure). This = so that the digital antenna can only be connected to the external and digital TV, not It is extremely inconvenient to build in a portable digital TV. "Users are carrying it." Therefore, the present invention proposes a mini-portable digital portable digital television interior, while 彳f ° # F, # u By using the inverse relationship between the wavelength of the electromagnetic wave resonance and the frequency u, the same antenna is cut into a plurality of frequency bands, which can be switched according to the frequency converter of the digital television, and the frequency is 笳Iflcr, 々, 吟, And switching the appropriate connection and cost to achieve the purpose of small-sized antenna.
