摘要:
An electronic device includes a housing and an internal pressure regulator valve. The internal pressure regulator valve includes a valve body of flexible material. The valve body has a valve hole and a hollow. The hollow is continuous with the valve hole and opens into the housing. Through the valve hole, gas is released to outside.

An antenna receiving apparatus includes, a first antenna; a second antenna that is synchronized with a frequency band different from the first antenna; a substrate that includes a receiving circuit connected to each of the first antenna and the second antenna; and a back lid that includes a conductor, wherein the conductor is in at least a portion of the back lid. The substrate includes a grounding surface of the first antenna. The substrate and the second antenna are positioned between the first antenna and the back lid. The second antenna is positioned on a side of the substrate opposite of the first antenna, and the second antenna is electrically connected to the conductor of the back lid and grounded.

When external pressure extremely increases, a waterproof vibration membrane tends to be resiliently deformed extremely toward the inside. However, an inward resilient deformation inhibiting member provided on the inner side of the waterproof vibration membrane with a space therebetween inhibits this extreme inward resilient deformation of the waterproof vibration membrane, whereby the waterproof vibration membrane is prevented from being ruptured or plastically deformed. On the other hand, when the internal pressure extremely increases, the waterproof vibration membrane tends to be resiliently deformed extremely toward the outside. However, an outward resilient deformation inhibiting member provided on the outer side of the waterproof vibration membrane with a space therebetween inhibits this extreme outward resilient deformation of the waterproof vibration membrane, whereby the waterproof vibration membrane is prevented from being ruptured or plastically deformed.

A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.
