Electric pianos don't have 3.5 sound card connectors

The reason electric pianos don't have a 35 sound card interface is because a 35 sound card interface is an audio interface used to connect to a computer or other external device for recording and playing audio. Electric pianos usually have a built-in sound module and speakers that can generate musical sounds directly from the internal sound source and play them through the built-in speakers, so a 35 sound card port is not needed.

It is worth expanding on the fact that electric pianos are often equipped with other interfaces, such as a MIDI interface or a USB interface.The MIDI interface can be used to connect to other MIDI devices, such as computers, music workstations, or synthesizers, for recording, editing, and controlling music.The USB interface can be used to connect to a computer or other device for interacting with music software and facilitating the recording and editing of music.

Despite the fact that electric pianos do not have a 35 sound card interface, they can still be connected to external devices through the use of other interfaces for more functionality and expandability. So, even without a 35 sound card interface, the electric piano can still fulfill most of the needs of music creation and performance.
