combine laptop speaker with external ones

a low impedance can be like a short and cause audio equipment to "fry" or burn out. To prevent speakers from forming a parallel resistance, resulting in a low impedance, there's a tab in the female jack that pushes away when a male jack is inserted. It opens the circuit to the laptop speakers to prevent parallel resistance, but allows the circuit to go through the connected speakers via the male jack. This is how most laptop audio jacks are setup to function.
In short, it's not wise to run both on a laptop. With some modification (minor on circuit level, but major in altering the female jack in a laptop), external speakers could be setup in 'series' to the internal. However, the higher resistance/impedance would cause a reduced volume and possible a muffled or reduced overall quality.

is there sofware that can split the signal alternately in two directions, the laptop speakers and the external ones, but with fast enough frequency to make it unnoticable for the ear? that way it wouldn't technically be in 'series'.

Doramius was referring to a sound system. The sound in a laptop is not treated the same way. You have a sound chip who control all the sound inside the laptop. The chip can control both of them at the same time, the internal and external speakers. But the manufacturer program the chip to use only one at the time, for a laptop. Why do you want to have both speakers, inside and external? Give me the make and model of your laptop, and I look if you have the possibility to do it.
