  • Acoustic output device
    Patent number: 11546683
    Abstract: To reduce the effect on the communication performance of an antenna to secure a good communication state with respect to the antenna. An acoustic output device includes a speaker for outputting sound, a cell having one surface facing in a facing direction represented by a predetermined direction, a control board for controlling predetermined parts, and an antenna for sending and receiving signals, the antenna having at least a portion spaced from the control board and the cell. The cell and the control board are positioned side by side with each other in directions different from thicknesswise directions of the control board. The facing direction is different from the directions in which the cell and the control board are side by side with each other. The antenna is positioned side by side with at least one of the control board or the cell in the thicknesswise directions or the facing direction.
