Wearable Sound Reproduction System Using Two End-Fire Arrays

We propose a personal sound reproduction system that uses two wearable end-fire loudspeaker arrays instead of a headphone to present the sound image. The prototype arrays rest on the listener’s chest so that the look direction of each array was directed to the listener’s ears. To prevent sound leakage around the listener, we designed a narrow directivity for each array. Moreover, we used a crosstalk canceler for localizing the sound image with head-related transfer functions. We verified the performance of the prototype by using simulations. A difference of approximately 15 dB of sound pressure was obtained between the look direction and the other directions. The crosstalk was suppressed from approximately 10 dB to 20 dB. Additionally, we also conducted a subjective listening test of the sound image localization. The right and left correct answer rate was approximately 90%, and the exact match was approximately 40%.
