Speakers may be classified into directional speakers and non-directional speakers according to whether or not radiated sound is directional.

In the case of a directional speaker, there is an advantage in that it is possible to concentrate sound at a target point because of the directionality of sound, but the sound wave energy radiated in a direction other than the target point is lost due to heat, etc., resulting in a decrease in efficiency. . In addition, in the case of the non-directional speaker, it is difficult to focus the sound only on a specific point as the emitted sound is radiated in all directions, but has an advantage of high efficiency unlike the directional speaker.

In this process, the air in the connection space 18a and the second inner space 14a is directed to the first inner space 12a. As air movement occurs from the second inner space 14a, the diaphragm 42 of the passivator 40 is directed upward.

Conversely, in the vibration process of the diaphragm 32 of the speaker 30, when the diaphragm 32 faces upward, the air pressure on the rear surface of the diaphragm 32 of the speaker 30 increases. In this process, the air in the first inner space 12a and the connection space 18a is directed to the second inner space 14a. Air movement occurs in the second inner space 14a, so that the diaphragm 42 of the passivator 40 faces downward.

In this way, in the process of outputting sound from the speaker 30, the vibration of the diaphragm 32 of the speaker 30 and the vibration of the diaphragm 42 of the passive radiator 40 may be out of phase. there is. In addition, the central axis of the diaphragm 32 of the speaker 30 and the central axis of the passive radiator 40 are provided to coincide.
