The third transmitting branch is connected to the keyboard 12 and the second channel output terminal of the first audio output port 114, and is used for transmitting the third audio signal to the second channel output terminal of the first audio output port. The fourth transmission branch is connected to the keyboard 12 and the first sound channel output end of the second audio output port, and is configured to transmit the fourth audio signal to the first sound channel output end of the second audio output port. The second channel output end of the first audio output port is, for example, the right channel output end thereof, and the first channel output end of the second audio output port is, for example, the left channel output end thereof.

In the present embodiment, the third audio signal may be configured to be the same as the second audio signal, and at the same time, the fourth audio signal may be configured to be the same as the first audio signal. At this time, the signals output by the first audio output port 114 and the second audio output port each include a first audio signal and a second audio signal. When the first audio output port 114 is connected to the first earphone and the second audio output port is connected to the second earphone, the user can hear the sound generated when the key in the first partition is pressed and the sound generated when the key in the second partition is pressed through both the first earphone and the second earphone. This scheme is suitable for the case where a single user plays the electronic piano 1. Further, in some embodiments, the first earphone and the second earphone may be included in the electronic piano 1 to be sold and/or used together with the electronic piano 1, and in other embodiments, the first earphone and the second earphone may be included outside the electronic piano 1, in which case the first earphone and the second earphone may be connected to the first audio output port and the second audio output port, respectively.

In addition, in the present embodiment, the third audio signal may also be configured to be the same as the first audio signal, and at the same time, the fourth audio signal may be configured to be the same as the second audio signal. At this time, the signal output from the first audio output port 114 includes only the first audio signal, and the signal output from the second audio output port includes only the second audio signal. When the first audio output port 114 is connected to the first earphone and the second audio output port is connected to the second earphone, the user can hear the sound generated when the key in the first partition is depressed through the first earphone without hearing the sound generated when the key in the second partition is depressed, and the user can hear the sound generated when the key in the second partition is depressed through the second earphone without hearing the sound generated when the key in the first partition is depressed. Therefore, this scheme is suitable for the case where two users play the electronic piano 1, and specifically, in the teaching process, by selecting an appropriate music score, the first user only needs to play the keys in the first partition, and the second user only needs to play the keys in the second partition. In the playing process, the first user can listen to the playing effect of the first user through the first earphone without being influenced by the playing of the second user, and similarly, the second user can listen to the playing effect of the second user through the second earphone without being influenced by the playing of the first user.

In practical applications, piano learners often do not have complicated playing requirements, which often require simple music to be played for practice, and thus their usual requirements can be satisfied even though the keyboard of the electronic piano is divided into a first partition and a second partition to be respectively allocated to two trainees for use. Therefore, based on the electronic piano 1 in this embodiment, in the piano teaching process, in order to overcome the limitation of cost and/or field and other factors, a proper music score can be selected in advance, so that the first learner only needs to play the keys in the first partition, and the second learner only needs to play the keys in the second partition, thereby achieving the effect that two learners share the same piano.

Optionally, the electronic piano 1 may further comprise a processing chip. The processing chip is configured to generate a first audio signal according to the collected key playing action in the first partition, and generate a second audio signal according to the collected key playing action in the second partition.
