The device 20d is physically separated from the earphone element 20a. Therefore, only the sound setting data is first transmitted to the headphone amplifier 20d, and the adjusted sound source signal is transmitted to the headphone element 20a by the headphone amplifier 22d. The rest of the disclosure is the same as the first embodiment. For reference, refer to FIG. 4 and the foregoing content, and details are not described herein again.

Based on the foregoing, it can be understood that, in various embodiments, the sound playback device adjusts the set or selected acoustic setting data to be rewritably stored in the rewritable acoustic data memory in the earphone device. . Therefore, when the external source signal is transmitted to the earphone device, the acoustic signal in the rewritable acoustic data memory can be transmitted through the digital signal processor. The data is processed for digital processing to overcome the sound playback device in a hardware manner, for example, a smart phone, a tablet computer or other sound playback device, and the various players are independent and need to be adjusted repeatedly. At the same time, since the earphone device can customize the demand of the consumer, the consumer can adjust the setting according to the needs of the user in different fields or environments, thereby providing a more economical choice for the consumer.

Although the preferred embodiment of the present invention is disclosed above, it is not intended to limit the creation of the novel, and any skilled person can make some changes and refinements without departing from the scope of the novel creation. The scope of patent protection of this new creation is subject to the definition of the scope of the patent application attached to this specification.
