Abstract
The present disclosure relates to an acoustic output device. The acoustic output device may include an earphone core, a controller, a power source, and a flexible circuit board. The earphone core may include at least one low-frequency acoustic driver configured to output sounds from at least two first guiding holes and the at least one high-frequency acoustic driver configured to output sounds from at least two second guiding holes. The controller may be configured to direct the at least one low-frequency acoustic driver to output the sounds in a first frequency range and direct the at least one high-frequency acoustic driver to output the sounds in a second frequency range. The power source may be configured to provide power supply for the earphone core. The flexible circuit board may be configured to connect the earphone core with the power source.
