Definitions
- the present invention relates to a portable audio / video reproducing device such as a mobile phone having a broadcast receiving function.
- This type of mobile phone can be configured by adding the configuration of the receiver main unit (110) of the digital broadcasting transceiver shown in FIG. 15 to the mobile phone shown in FIG. 14, for example. Since the main body (110) is composed of a large number of circuits, there is a problem in that the whole mobile phone becomes large and the weight of the whole mobile phone greatly increases. In addition, since power is supplied to a large number of circuits constituting the receiver main body (110), there is a problem that power consumption is significantly increased.
- An object of the present invention is to provide a portable audio and video reproducing apparatus with a broadcast receiving function, which is small and lightweight as a whole and consumes less power. Disclosure of the invention
- An audio signal processing means connected to the interface means for performing signal processing on an audio signal supplied from the outside to generate a signal to be output as speed, and supplying the signal to the speed;
- Interface means connected to the interface means of the apparatus main body; signal supply means for supplying audio and video signals contained in the received television broadcast signal to the interface means
- the audio signal and the video signal downloaded from the Internet, and the audio signal and the video signal stored in the built-in memory are supplied to the audio signal processing unit and the video signal processing unit, respectively.
- the supplied acoustic signal is subjected to signal processing to generate a signal to be supplied to the speaker, and the signal is supplied to the speaker.
- the supplied video signal is subjected to signal processing to create a signal to be supplied to the display, and the signal is supplied to the display. In this way, the function of reproducing and outputting the audio signal and the video signal is exhibited.
- the audio signal and the video signal included in the received television broadcast signal are supplied to the interface unit by the signal supply unit of the broadcast receiving unit, and the audio signal and the video signal supplied to the interface unit are Respectively The signal is supplied to the audio signal processing means and the video signal processing means via the interface means.
- the acoustic signal processing means the supplied acoustic signal is subjected to signal processing to generate a signal to be supplied to the speaker, and the signal is supplied to the speaker.
- the supplied video signal is subjected to signal processing to generate a signal to be supplied to the display, and the signal is supplied to the display.
- the broadcast receiving unit when used as an audio / video playback device, can be removed from the device body to further reduce the size, weight, and power consumption. Furthermore, when the life of one of the main unit and the broadcast reception unit has expired, only the one end of the life of the main unit or the broadcast reception unit can be replaced, and the other main unit or the main unit of the broadcast reception can be continued. Can be used.
- the main body of the apparatus includes a power supply unit serving as a power source for a speaker, a display, an audio signal processing unit, and a video signal processing unit, while the broadcast reception unit has a power supply unit serving as a power supply for a signal supply unit.
- a power supply means for outputting a voltage is adopted and a power supply means for outputting a voltage of the same magnitude as the voltage to be applied to the signal supply means is adopted as a power supply means for the broadcast receiving unit, There is no need for a means for increasing or decreasing the output voltage of the power supply means, and it is possible to further reduce the size, weight, and power consumption of the entire device.
- the battery pack is accommodated in the accommodation portion of the casing of the device main body.
- the pair of input terminals of the device main body and the pair of output terminals of the battery pack come into contact with each other, and the power obtained from the battery pack is transmitted to the speaker, display, audio signal processing means, and video signal processing means of the device main body. Supplied.
- These speakers and displays In other words, the audio signal processing means and the video signal processing means execute the above-described operations upon receiving the power supply.
- the power supply line for supplying power from the battery pack to the speaker, the display, the audio signal processing means, and the video signal processing means of the apparatus main body when used as an audio / video reproducing apparatus is provided for broadcast reception.
- it is also used as a power supply line for supplying power from the power supply means of the broadcast receiving unit to the speaker, display, audio signal processing means, and video signal processing means of the apparatus body.
- the power supply means of the broadcast receiving unit is used as a power supply source when used as a broadcast receiving device requiring a large amount of power, so that power is supplied when used as an audio-video reproducing device.
- the capacity of the battery pack of the apparatus main body used as a power source can be reduced, and thereby the further miniaturization and weight reduction of the apparatus main body can be realized.
- FIG. 1 is an exploded perspective view showing a state in which a broadcast receiving unit is removed from the telephone body of the first embodiment.
- FIG. 2 is a perspective view illustrating a state where the broadcast receiving unit is attached to the telephone body.
- FIG. 3 is a block diagram showing an electrical configuration of the telephone body and the broadcast receiving unit.
- FIG. 7 is an exploded perspective view of the state where the broadcast receiving unit has been removed from the telephone main body, as viewed from the rear side.
- FIG. 8 is a perspective view of a state in which the broadcast receiving unit is attached to the telephone body, as viewed from the rear side.
- FIG. 9 is a block diagram showing an electrical configuration of the telephone body.
- FIG. 13 is a perspective view showing a state where the broadcast receiving unit is attached to a telephone body.
- FIG. 15 is a block diagram showing a conventional portable digital broadcast receiver having a recording function.
- BEST MODE FOR CARRYING OUT THE INVENTION an embodiment in which the present invention is applied to a mobile phone will be specifically described based on two examples.
- a mobile phone with a broadcast receiving function has a telephone body (1) that exhibits a function as a mobile phone and a telephone body (1) that can receive television broadcast waves. ), And a broadcast receiving unit (4) that is detachably attached to the broadcast receiving unit.
- the broadcast receiving unit (4) has a box casing (40), and the casing (40) has a connector (41) protruding therefrom and a broadcast wave receiving antenna (42). ) Is protruding.
