Abstract

Housings on the right/left of the noise cancellation headphone, where a speaker unit is incorporated, are connected to each other with a headband, and a battery receiving portion is provided on a side surface of at least one of the right and left housings. The battery receiving mechanism includes: a battery receiving portion provided in the side surface of the housing; a battery lid opening and closing the battery receiving portion; and a flexible connecting member preventing the battery lid from dropping off from the housing in a state where the battery lid opens the battery receiving portion. The housing and the battery lid each include an engagement part which engages with each other by pushing in the battery lid in a direction intersecting with the side surface of the housing, and the battery lid occupies a part of the side surface of the housing.

Claims

1. A battery receiving mechanism for a noise cancellation headphone, in which the noise cancellation headphone includes, respectively, on the right and left thereof, a housing having a speaker unit incorporated therein, both housings are connected to each other with a headband, and a battery receiving portion is provided on a side surface of at least one of the right and left housings, the battery receiving mechanism comprising:

a battery lid opening and closing the battery receiving portion; and

a flexible connecting member preventing the battery lid from dropping off from the housing in a state where the battery lid opens the battery receiving portion,

wherein the housing and the battery lid each include an engagement part which engages with each other by pushing in the battery lid in a direction intersecting with the side surface of the housing,

wherein the battery lid occupies only a part of the side surface of the housing, and

wherein the engagement part on the housing is an engaging recessed part and the engagement part on the battery lid is an engaging projection part which fits into the engaging recessed part and engages with an edge of the engaging recessed part due to an elastic force.

2. The battery receiving mechanism for a noise cancellation headphone according to claim 1, wherein the engaging projection part includes a downwardly inclined surface and an upwardly inclined surface, toward a projection direction.

3. The battery receiving mechanism for a noise cancellation headphone according to claim 1, wherein the connecting member is a plate-like member, and includes, at both ends, a latching portion extending to both sides wider than a width of this plate-like member, and wherein the latching portion is latched to a receptacle of the housing and a receptacle of the battery lid.

4. The battery receiving mechanism for a noise cancellation headphone according to claim 3, wherein the receptacle on the housing side is a receptacle hole, and wherein the receptacle on the battery lid side has a confining structure comprising a hook-shaped projection confining the latching portion of the connecting member.

5. The battery receiving mechanism for a noise cancellation headphone according to claim 4, wherein the latching portion of the connecting member can be removably attached to the receptacle of the housing and the receptacle of the battery lid, respectively, due to its flexibility.

6. The battery receiving mechanism for a noise cancellation headphone according to claim 3, wherein the latching portion of the connecting member can be removably attached to the receptacle of the housing and the receptacle of the battery lid, respectively, due to its flexibility.
