Abstract

A sound reproducing apparatus includes a display unit, a board 22 , a diaphragm panel 23 , and an electroacoustic transducer 26 . The display unit displays an image on a display surface. The board 22 is composed of a material which transmits visible light and arranged such that a first space is provided between the display surface of the display unit and the board 22 . The diaphragm panel 23 is composed of a material which transmits visible light and arranged on the opposite side of the board 22 from the display unit such that a second space is provided between the board 22 and the diaphragm panel 23 . The electroacoustic transducer 26 emits sound into the second space.

Claims (17)

1. A sound reproducing apparatus comprising:

a display unit operable to display an image on a display surface;

a board composed of a material which transmits visible light and arranged such that a first space is provided between the display surface of the display unit and the board;

a diaphragm panel composed of a material which transmits visible light and arranged on the opposite side of the board from the display unit such that a second space is provided between the board and the diaphragm panel; and

at least one electroacoustic transducer for emitting sound into the second space,

wherein the board has a sound hole, and

wherein the electroacoustic transducer is arranged so as to cover the sound hole.

2. The sound reproducing apparatus according to claim 1 , further comprising:

a case having an opening which is covered by the diaphragm panel,

wherein the case contains therein the board, the display unit, and the electroacoustic transducer.

3. The sound reproducing apparatus according to claim 2 , wherein the diaphragm panel is composed of a touch panel.

4. The sound reproducing apparatus according to claim 2 , further comprising:

an antenna for receiving a signal; and

a signal processing unit operable to perform predetermined signal processing on the signal received by the antenna and inputting the processed signal to the electroacoustic transducer.

5. The sound reproducing apparatus according to claim 4 , wherein

a number of the at least one electroacoustic transducer is two, and

the signal processing unit inputs to one of the two electroacoustic transducers a signal received by the antenna if the signal includes an incoming speech sound signal, and inputs to the other one of the two electroacoustic transducers a signal received by the antenna if the signal includes a signal other than an incoming speech sound signal.
