Description

  The present invention relates to open / close detection using a magnet and a sensor member used in a two-fold cellular phone.

Conventionally, as an open / close detection using this type of magnet and sensor member, a first casing and one end are rotatably attached to one end of the first casing and are folded with respect to the first casing. A second housing that is positioned in a closed state or an opened state, a sound generation member that is provided in the first housing and includes at least a magnet, and is provided in the second housing and folded. A sensor member that detects a magnetic force and has a sensor member that is disposed at a position facing the sounding member in a state of being opened is known. (See Patent Document 1)
According to this, it is not necessary to provide a magnet separately from the sound generation member in order to detect the opening and closing of the mobile phone, and the number of parts constituting the mobile phone can be reduced.
JP 2003-87374 A

  However, the one described in Patent Document 1 is only intended to reduce the number of parts, and when attempting to use the present invention, it is necessary to dispose a sensor member at a position facing the sound generation member. There existed a subject that the arrangement | positioning freedom degree of a member was restricted.

  The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to provide a mobile phone configured to have a degree of freedom in the arrangement position of the sensor member. .

The mobile phone according to the present invention has a first casing and one end rotatably attached to one end of the first casing, and is folded or opened with respect to the first casing. A second casing that is positioned in the first casing, a sounding member that is provided in the first casing in the previous period and includes at least a magnet, a sheet metal plate that contacts the magnet portion of the previous sounding member, And a sensor member for detecting a magnetic force, which is provided in the second housing and disposed at a position facing the sheet metal of the previous magnetic body in a folded state.

  With this configuration, the sensor member detects the magnetic force of the magnetic metal plate. As a result, there is no need to dispose the sensor member at a position facing the sounding member as in the prior art. As a result, the arrangement position of the sensor member can be given a degree of freedom.

In the present invention, the first casing and one end are rotatably attached to one end of the first casing in the previous period,
A second casing that is positioned in a folded state or an opened state with respect to the first casing in the previous period, and a sounding member that is provided in the first casing and includes at least a magnet When,
Magnetic sheet metal that contacts the magnet portion of the previous period sounding member, and a sensor member that is provided in the second casing of the previous period and is disposed in a position facing the previous metal sheet in the folded state. The sensor member is configured to detect the magnetic force of the magnetic sheet metal, thereby providing a degree of freedom in the arrangement position of the sensor member.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a perspective view of a mobile phone according to the first embodiment of the present invention.

  As shown in FIG. 1, the mobile phone 1 according to the first embodiment of the present invention includes a first casing 2 and a second casing 3 that is rotatably attached to the first casing 2. .

  The first housing 2 is formed to extend to one end 2a and the other end 2b, includes a magnet, and includes a receiver 4 as a sounding member that emits sound, and a magnetic body that contacts the magnet portion 4a of the receiver 4 in the previous period. It has a sheet metal 5. The receiver 4 is a member for transmitting the voice of the other party to the user, and is configured by a vibrating body having a magnet 4a.

  The first housing 2 has a main surface 2c, and a window 6 is fitted on the main surface 2c. The window 6 is made of a transparent member such as an acrylic resin. A liquid crystal display is provided in the first housing 2, and the user can visually recognize the character information displayed on the liquid crystal display through the window 6. Window 6 is provided in the central portion of main surface 2c.

  The second housing 3 is formed so as to extend to one end 3a and the other end 3b, and is arranged at a position facing the magnetic metal plate 5 in a state in which the cellular phone 1 is folded, and detects a magnetic force. A member 7 is provided.

  The second housing 3 has a main surface 3c, and a plurality of operation keys 8 are provided on the main surface 3c. The operation keys 8 are provided at the center of the second housing 3 and a plurality of operation keys 8 are regularly arranged in the vertical direction and the horizontal direction.

  Next, a cross-sectional view when the cellular phone 1 according to the first embodiment of the present invention is folded will be described. FIG. 2 is a perspective view when the cellular phone 1 according to the first embodiment of the present invention is folded, and FIG. 3 is a sectional view taken along line AA in FIG.

  As shown in FIG. 3, a space is formed inside the first housing 2, and the substrate 9 is disposed in this space. The substrate 9 has a plate shape, and a liquid crystal 10 composed of a liquid crystal display is disposed on the surface thereof. The liquid crystal 10 is attached to the substrate 9. The receiver 4 is attached to the first housing 2 by a magnetic metal plate 5 that contacts the magnet 4a of the receiver 4 via a cushion.

  A space is formed inside the second housing 3, and a substrate 11 is provided in the space. A plurality of switches 12 are provided on the surface of the substrate 11. An operation key 8 is provided at a position where the switch 12 can be pressed. A sensor member 7 is provided on the surface close to the main surface 3c. When folded, that is, when the housing 3 and the housing 2 are close to each other, the sensor member 7 detects the magnetic force generated by the magnetic metal plate 5.

  A central processing unit 13 is provided on the surface of the substrate 11 on the side far from the main surface 3c. The central processing unit 13 is connected to the switch 12 and the sensor member 7. When the sensor member 7 detects the magnetic force, a signal is sent from the sensor member 7 to the central processing unit 13. As a result, the central processing unit 13 sends a signal for identifying an open / closed state such as reducing power consumption to the liquid crystal 10. The substrate 11 and the substrate 9 are electrically connected by a flexible substrate 14. Thereby, reduction of the power consumption of the liquid crystal 10 is performed in the folded state.

  In the cellular phone according to the first embodiment configured as described above, the sensor member 7 detects the magnetic force of the magnetic metal plate contacting the magnet 4a of the receiver 4, so that the cellular phone 1 is open. It is determined whether it is in a folded state. Since the sensor member 7 detects the magnetic force of the sheet metal, it is possible to detect the magnetic force by changing the shape of the sheet metal in accordance with the arrangement position of the sensor member 7, and therefore, the degree of freedom in the arrangement position of the sensor member is increased. You can have it.

INDUSTRIAL APPLICABILITY The present invention is useful for opening / closing detection using a magnet and a sensor member for detecting magnetic force used in a two-fold cellular phone.
