Flexible loudspeakers that can be easily distributed in the surrounding environment are essential for creating immersive experiences in human-machine interactions, as these devices can transmit acoustic information conveniently. In this paper, we present a flexible electret loudspeaker that offers numerous benefits, such as eco-friendly, easy fabrication, flexible customization, strong durability, and excellent outputs. The output sound pressure level (SPL) and frequency response characteristic are optimized according to the simulation and experiment results. At a distance of 50 meters, a large-size loudspeaker (50 × 40 cm²) can produce an average SPL of 60 dB (normal SPL range of human voices is between 40 to 70 dB). The frequency response of our loudspeaker is high and relatively consistent up to 15 kHz, which covers the normal frequency range of human voices (<8 kHz). As demonstrated in this work, our loudspeakers can be used for scalable applications, such as being integrated with curtains or hung up like posters, offering a promising and practical solution for creating better human-machine interaction experiences.

可以轻松分布在周围环境中的柔性扬声器对于在人机交互中创造沉浸式体验至关重要，因为这些设备可以方便地传输声学信息。在本文中，我们提出了一种柔性驻极体扬声器，它具有许多优点，例如环保、易于制造、灵活定制、强大的耐用性和出色的输出。根据仿真和实验结果优化了输出声压级（SPL）和频率响应特性。在50米的距离上，一个大尺寸扬声器（50×40cm ² ）可以产生60dB的平均声压级（人声的正常声压级范围在40到70dB之间）。我们的扬声器的频率响应很高且相对一致，最高可达 15 kHz，涵盖了人声的正常频率范围 (<8 kHz)。正如这项工作所证明的，我们的扬声器可用于可扩展的应用，例如与窗帘集成或像海报一样悬挂，为创造更好的人机交互体验提供了一个有前途且实用的解决方案。
