Claims

[Scope of utility model registration request]

A composite type direct speaker unit consisting of a main speaker unit attached to a sound box and radiating sound directly to the outside, and an auxiliary speaker unit installed within the sound box so as to radiate the same sound to the back of the main speaker unit. When the radiant speaker device is embedded in the door of a vehicle, the auxiliary speaker unit is arranged in the opposite direction to the main speaker unit and arranged next to the main speaker unit, thereby reducing the thickness of the speaker device and further increasing the auxiliary speaker unit. A vehicle-mounted speaker device characterized in that the speaker unit is connected to a closed space using the inside of an armrest attached to a door via a pipe to supplement the closed space behind the speaker unit.
