摘要: First and second color liquid crystal display elements of the negative guest-host type are disposed in adjacent and opposing relation to each other and the color liquid crystal display elements provide display in different colors, at least one of electrodes of each color liquid crystal display element having formed therein a display pattern. By the control of a changeover switch, an alternating drive voltage is applied from a drive circuit to one of the first and second color liquid crystal display elements to change the color of a background of the display in accordance with the control of the changeover switch.

摘要: A condenser microphone in which a back electrode, disposed oppositely to the rear surface of a diaphragm, and a circuit assembling plate disposed oppositely to the rear surface of the back electrode, are held in a holder.Electronic circuit elements are attached to only one surface of the circuit assembling plate, and the other surface thereof is faced toward the rear surface of the back electrode with a predetermined distance provided therebetween. A back chamber, defined by a space between the back electrode and the circuit assembling plate, and enclosed by the holder improves the characteristics of microphone frequency response.
