Ultrasonic Transmitter / Level Shifter

For an ultrasonic transmitter, if I connect one side to a +9v/0v pulse train (1010101010) and connect the other side to a inverted +9v/0v pulse train (0101010101), is the transmitter going to produce a +9v/-9v pulse train?

If it doesn't, what is the simplest way to shift the +9v/0v pulse train to -9v/0v ?

It is common for an ultrasonic transmitter to use a bridge to drive both ends of the transducer so its p-p signal is nearly double the supply voltage. The bridge inverts the signal that feeds one end of the transducer.
