Abstract: A speaker drive unit includes a control signal generation unit and a signal processing unit. The control signal generation unit generates a control signal on the basis of detection signals generated by a plurality of detection units that is disposed in one-to-one correspondence with a plurality of actuators that vibrates a diaphragm, and detects vibration conditions. The signal processing unit includes a plurality of signal systems corresponding one-to-one to the plurality of actuators. The signal systems provide a drive signal to the corresponding actuators on the basis of the same audio signal. The drive signal generated by at least one signal system of the signal systems is controlled by the control signal.

Abstract: Provided is an information processing apparatus that carries out a process of deriving a head related transfer function. The information processing apparatus includes a detection unit that detects a position of a head of a user, a storage unit that stores a head related transfer function of the user, a determination unit that determines a position of a sound source for measuring the head related transfer function of the user based on the position of the head detected by the detection unit and information stored in the storage unit, a control unit that controls the sound source to output measurement signal sound from the position determined by the determination unit, and a calculation unit that calculates the head related transfer function of the user based on collected sound data obtained by collecting, at the position of the head, the measurement signal sound output from the sound source.

Abstract: Provided is a sound output apparatus that is used by being worn in the vicinity of the ear of a listener and is capable of outputting sound over a wide frequency band.
The sound output apparatus includes: a first sound generation unit configured to generate a low frequency band; a sound guiding unit with a hollow structure, having one end coupled to the first sound generation unit, and the other end as a sound emission unit including an open end; and a second sound generation unit that is disposed at a place closer to the sound emission unit than the first sound generation unit and generates a high frequency band. It is preferable that the sound guiding unit have a joint unit that takes in the sound from the second sound generation unit and a section from the joint unit to the sound emission unit have a low impedance.
