Note that an area where the display 14 is arranged on the display surface is also referred to as a display area 1.

  As shown in FIG. 2, the speaker 23 and the antenna 20 are arranged close to each other. A region including the speaker 23 and the antenna 20 is covered with a predetermined cover 24. A resin or the like is conceivable as a material for this cover, and it does not have conductivity. The cover 24 is preferably distinguishable visually or tactilely. For example, a cover that is visually recognizable such as a color different from other areas of the display surface, or a cover that is tactilely distinguishable such as being roughened unlike other areas of the display surface is preferable. . Moreover, the quality of the audio | voice output from the speaker 23 can be improved by using the cover which has a net-like shape. In addition, the sound hole of the speaker 23 is included in the arrangement region of the speaker 23 in FIG.

  The first housing 11 contains a first circuit board 22. The first circuit board 22 includes a matching unit 21, an LNA (Low Noise Amplifier) 25, a reception processing unit 26, and a control unit 16. 4 illustrates that the LNA 25, the reception processing unit 26, and the control unit 16 are provided on the first circuit board 22, but may be provided on the second circuit board of the second housing 12.

  The matching unit 21 has a function of matching the impedance of the antenna 20 and the input impedance of the LNA 25.

  The LNA 25 amplifies the high frequency signal from the antenna 20. The high-frequency signal is, for example, a broadcast signal other than DTV such as a DTV signal or a digital radio signal, and an audio signal or an image signal acquired from an external device.

  The reception processing unit 26 performs reception processing on the signal amplified by the LNA 25. In the reception process, for example, a tuning process for selecting a frequency band signal used in the DTV from the amplified signal, a demodulation process for demodulating a signal in the frequency band selected by the tuning process, and the like are performed.

  FIG. 5 is a diagram showing an example of the relationship between the resonant frequency of the high-frequency signal received by the antenna and VSWR (Voltage Standing Wave Ratio). A curved line L1 shows a case where a user's finger is placed in the antenna formation region 2 on the display surface. A curved line L2 shows a case where the user's finger is placed in the gripping area 3 on the display surface. When the frequency band between the frequencies f1 and f2 is a desired frequency band, it is desirable that the VSWR is equal to or less than a predetermined threshold Ta in this frequency band. From the curves L1 and L2, desired communication characteristics cannot be obtained when a finger is placed in the antenna formation area 2, and desired communication characteristics can be obtained when a user's finger is placed in the grip area 3. I understand that it is possible.

  The control unit 16 extracts an image signal and an audio signal from, for example, a DTV signal subjected to reception processing by the reception processing unit 26. Then, an image is displayed on the display 14 based on the image signal, and sound is output to the speaker 23 based on the sound signal. Note that in the case of only one of the image signal and the audio signal, only one of the image display and the audio output is performed.

  According to such a portable wireless device 10, by covering the antenna forming region 2 with the predetermined cover 24, the vicinity of the antenna 20 is not covered with a hand, and good communication characteristics can be ensured.

A metal or the like is conceivable as a material for the cover, and it has conductivity. Moreover, it is preferable that the cover 24b can be visually or tactilely discriminated. For example, a cover that is visually recognizable such as a color different from other areas of the display surface, or a cover that is tactilely distinguishable such as being roughened unlike other areas of the display surface is preferable. . Moreover, the quality of the audio | voice output from the speaker 23 can be improved by using the cover which has a net-like shape.

  Thus, by covering the antenna formation region 2 with the predetermined cover 24b, the vicinity of the antenna 20 is not covered with a hand or a finger, and good communication characteristics can be ensured.

  FIG. 7 is a diagram illustrating an example of an electrical connection relationship in the portable wireless device 10B. In FIG. 7, the electrical connection relationship is taken into consideration, and the positional relationship in which each part is actually arranged is not taken into consideration.

  4 and 7 is that an insulating member 28 is disposed between the antenna 20 and the conductive cover 24b. The insulating member 28 is a plastic material such as ABS, for example.
