Abstract
【解決手段】本発明にかかる電子機器1は、圧電素子30と、該圧電素子30により振動する振動板10とを備え、当該振動板10により、気導音と、人体の一部を振動させて伝える振動音とを発生させる電子機器1において、さらに前記気導音の一部あるいは全部を聞こえにくくする気導音低減部を備える。
【選択図】図1
Description
図3は第1の実施形態に係る電子機器1の実装構造を示す図である。図3(a)は正面図、図3(b)は図3(a)におけるb−b線に沿った断面図である。図3に示す電子機器1はパネル10としてガラス板であるタッチパネルが筐体60(例えば金属や樹脂のケース)の前面に配されたスマートフォンである。パネル10及び入力部40は筐体60に支持され、表示部20および圧電素子30は、それぞれ接合部材70によりパネル10に接着されている。接合部材70は、熱硬化性あるいは紫外線硬化性等を有する接着剤や両面テープ等であり、例えば無色透明のアクリル系紫外線硬化型接着剤である光学弾性樹脂でもよい。パネル10、表示部20および圧電素子30は、それぞれ略長方形状である。
図5は第2の実施形態に係る電子機器1の実装構造を示す図である。図5(a)は正面図、図5(b)は図5(a)におけるb−b線に沿った断面図、図5(c)は図5(a)におけるc−c線に沿った断面図である。図5に示す電子機器1はパネル10として表示部20を保護するカバーパネル(アクリル板)が上側の筐体60の前面に配された折りたたみ式の携帯電話である。第2の実施形態では、パネル10と圧電素子30との間には、補強部材80が配置される。補強部材80は、例えば樹脂製の板、板金またはガラス繊維を含む樹脂製の板である。すなわち、第2の実施形態に係る電子機器1は、圧電素子30と補強部材80とが接合部材70により接着され、さらに補強部材80とパネル10とが接合部材70により接着される構造である。また、第2の実施形態では、表示部20は、パネル10に接着されるのではなく、筐体60によって支持されている。すなわち、第2の実施形態に係る電子機器1は、表示部20がパネル10と離間しており、表示部20と筐体60の一部である支持部90とが接合部材70により接着される構造である。なお、支持部90は、筐体60の一部としての構成に限定されず、金属や樹脂等により筐体60から独立した部材として構成することが可能である。また、スピーカー62は、筐体60内部に配置され、特に、パネル10と対向する背面側に配置される。なお、スピーカー62の放音口には、防水用部材を設けても良い。
