登録請求の範囲第１項記載のスピーカ装置。[Claims for Utility Model Registration] 1. A main voice coil 1 and a sub-voice coil 2 are coupled to the diaphragm 3 of an electrodynamic speaker having a single diaphragm 3, and each or a common magnetic gap 8 is formed. The main voice coil 1 is directly connected to the speaker input terminal 4, and the sub voice coil 2 is connected to the speaker input terminal 4 via a level controller 6 and a low-pass filter 7.
The main voice coil 1 is connected to the main voice coil 1, where a voice current of all bands flows into the main voice coil 1, and the sub voice coil 2 receives a low-frequency voice current whose level is adjusted with respect to the voice current of all bands flowing through the main voice coil 1. A speaker device configured to receive audio current. 2. The speaker device according to claim 1, wherein the main voice coil 1 and the sub voice coil 2 are wound around a common voice coil bobbin 5 and connected to a diaphragm 3.
