Document Type and Number:
Japanese Patent JP6802954
Kind Code:
B2
Abstract:
To provide a digital drive type headphone capable of outputting high-quality sound waves by preventing an entry of external noises into a transition cable used between a pair of left and right electroacoustic transducers.SOLUTION: In a connection structure of a digital drive type electroacoustic transducer having a signal conversion unit (signal processing circuit) for driving a diaphragm by a digital signal and converting it into a sound wave, in the digital drive type electroacoustic transducer (headphone 100) composed of a pair of left and right, one digital drive type electroacoustic transducer (headphone unit 101) connected to a digital signal source 50 of a digital signal via a first signal line 51 and the other digital drive type electroacoustic transducer connected to the one digital drive type electroacoustic transducer are connected via a second signal line (crossover cable) 11. The second signal line is composed of a stranded wire structure in which a positive input line and a negative input line are paired.SELECTED DRAWING: Figure 4
