Summary:PROBLEM TO BE SOLVED: To provide a mobile device including a magnet unit that is thermally coupled to a heat sink portion of a device housing.SOLUTION: A mobile device comprises: a speaker driver that includes a magnet unit; a housing having a heat sink portion that is made of a material having a high thermal conductivity; and a thermal component. The heat sink portion has a first face that is coupled to the speaker driver and a second face that is exposed to the exterior of the mobile device. The thermal component binds the speaker driver to the first face of the heat sink portion to create a cooling path from the magnet unit to the exterior of the mobile device. Other embodiments are also described. 【課題】装置ハウジングのヒートシンク部分に熱的に結合された磁石ユニットを備えた移動装置を提供する。【解決手段】この移動装置は、磁石ユニットを含むスピーカドライバと、熱伝導率の高い材料で作られたヒートシンク部分を有するハウジングと、熱的コンポーネントとを備えている。ヒートシンク部分は、その第１の面がスピーカドライバに結合され、そして第２の面が移動装置の外部に露出される。熱的コンポーネントは、スピーカドライバをヒートシンク部分の第１の面に結合して、磁石ユニットから移動装置の外部への冷却経路を形成する。他の実施形態も説明される。【選択図】図３
