Portable electronic device
View Patent ↗A portable electronic device includes an electronic component, a spring terminal extending from the electronic component to supply power to the electronic component, a circuit component having a power supply section contacting the spring terminal, and a stopper for restricting a movement of the electronic component. The spring terminal has a reversible deformation limit of elastic deformation. The stopper restricts the movement of the electronic component within the reversible deformation limit of the spring terminal. This portable electronic device prevents a spring pressure of the spring terminal from decreasing, hence supplying power to the electronic component stably.
1. A portable electronic device comprising:
a case;
an electronic component accommodated in said case;
a spring terminal accommodated in said case and extending from said electronic component, said spring terminal being arranged for supplying power to said electronic component, said spring terminal being made of elastic metallic material having a reversible deformation limit of elastic deformation;
a circuit component accommodated in said case and having a power supply section, said power supply section contacting said spring terminal; and
a stopper, not movable with said circuit component upon movement of said circuit component away from said electronic component, for restricting movement of said electronic component to within the reversible deformation limit of said spring terminal, said stopper being accommodated in said case and extending from an inner wall of said case;
wherein said circuit component is movable, within said case, with respect to said stopper away from said electronic component to prevent said circuit component from becoming closer than a predetermined distance from said electronic component.
2. The portable electronic device of claim 1 , wherein
said stopper is configured and arranged so that, upon movement of said electronic component toward said stopper from a position spaced away from said stopper, said stopper is operable to contact said electronic component to restrict the movement of the electronic component.
3. The portable electronic device of claim 1 , wherein said electronic component comprises an electric acoustic transducer.
4. The portable electronic device of claim 3 , wherein
said electric acoustic transducer includes a frame and a magnetic circuit, and
said stopper is operable to contact said frame to restrict the movement of said electronic component.
5. The portable electronic device of claim 3 , wherein
said electric acoustic transducer includes a frame and a magnetic circuit, and
said stopper is operable to contact said magnetic circuit to restrict the movement of said electronic component.
6. The portable electronic device of claim 1 , further comprising
a component, wherein said stopper is operable to contact said component to restrict the movement of said electronic component.
7. The portable electronic device of claim 1 , wherein said stopper is formed unitarily with said case.
