Description

  The present invention relates to a swivel mobile phone device in which a second housing is connected to a first housing through a connecting portion so as to be turnable.

In recent years, some mobile phones can be folded when not in use normally and can be stored compactly in bags or pockets. If folded in this way, the operation part is not exposed, so key switches etc. A foldable mobile phone has been developed and is widely used, which does not have to worry about troubles such as being accidentally pressed and turning on the power without your knowledge.
In this foldable mobile phone, usually, it is often miniaturized by folding it when it is in a standby state, but in such a folded state, the transmitter and receiver are not exposed to the outside and hidden. I can't talk.

  As described above, in the case of a foldable mobile phone, it is necessary to open and use both the upper and lower housings during a call. For example, as described in Patent Document 1, the upper housing is exposed in a folded state. There is also proposed a mobile phone that is further provided with a transmitter and receiver on the active surface (hereinafter referred to as the “outer surface”) and that can be used in this folded state (referred to as the “closed state”). ing. However, in such a foldable mobile phone, it is necessary to provide two transmitting parts (microphones) and two receiving parts (speakers), which increases the number of speakers and microphones installed.

  Therefore, for example, as described in Patent Document 2, even when the upper and lower casings are folded, the transmission section of the lower casing is exposed to the outside without being blocked by the upper casing. A configuration having such a configuration is also proposed. In the foldable mobile phone having such a configuration, two telephone receivers are required in order to make a call even when the upper and lower casings are folded. it can.

  By the way, all of those described in these publications are configured so that a call can be made even when the upper and lower casings are folded, so if the power is turned on in the folded closed state, It is convenient because it can respond promptly when calling. However, since the screen of the display section of the upper housing is not exposed to the outside in the folded state as described above, various inconveniences such as inability to directly confirm who the other party is on the screen. Was produced.

Therefore, in recent years, instead of opening and closing the upper and lower housings, only the upper housing is rotated 180 degrees from the open state (or from the fully closed state) (hereinafter referred to as “turning”). After reversing both sides, the upper and lower housings are closed together to expose the surface of the upper housing with the display (hereinafter referred to as the “viewing surface”) to the outside. (Hereinafter referred to as “standby state”), a mobile phone (hereinafter referred to as “swivel type mobile phone”) that allows the image on the display unit to be directly visible from the outside even in the standby state has been proposed and developed. Has been.
JP-A-11-187098 (FIGS. 1 and 3) Japanese Patent Laid-Open No. 2001-211241 (FIG. 2)

  In addition, as with the openable mobile phone, it has been considered that such a swivel mobile phone can make a call in the same reception unit in the standby state in the standby state. However, in the conventional configuration in which the receiving unit is arranged at the upper end of the upper casing, the receiving unit is arranged in a state of being overlapped with (or close to) the transmitting unit in the standby state. As a result, the voice from the receiver may be picked up by the transmitter, and the interval between the receiver and transmitter becomes very close, which can correspond to the distance between the ear and mouth. Since the user cannot move the transmitter to the mouth, the receiver cannot be placed on the ear.

  The present invention solves these problems, and not only in an open state in which the first housing and the second housing are opened, but also in a standby state, a single receiver (speaker). An object of the present invention is to provide a swivel-type mobile phone device that can be used for both telephone calls.

The swivel mobile phone device of the present invention includes a first casing having a key operation unit and a transmitter, a second casing having a display unit and a receiver, and the second casing as the first casing. In a swivel type mobile phone device comprising a hinge part that is pivotably connected to the housing of
The earpiece of the second casing is constituted by a flat panel speaker that emits sound by vibrating a flat diaphragm.

  According to such a configuration, not only the first and second housings are opened, but also the standby portion in which the first and second housings are folded, there is only one receiver. Calls can be made.

That is, this can be covered to some extent with the accuracy of a microphone or the like even if the distance between the mouth of the transmitter and the transmitter is separated to some extent. On the other hand, the volume of sound emitted from the receiver (speaker) cannot be increased without limitation from the consideration of the surrounding people, and the listener's ear must be brought close to the receiver (speaker). Further, in order to avoid the trouble of picking up the sound from the receiver unit at the transmitter unit, the transmitter unit cannot be arranged very close to the receiver unit.
For this reason, in order to enable a call not only in the state where the first and second housings are opened, but also in a standby state where the first and second housings are closed, a receiving unit that emits sound locally such as a conventional speaker is provided. If it is used, it is necessary to additionally provide a receiving part in a part close to the ear in the standby state (and a part away from the transmitting part to some extent), and two receiving parts are absolutely necessary.

Therefore, the swivel mobile phone according to the present invention uses a panel speaker configured to emit sound with a certain degree of spread in a plane, and is arranged so that the receiving unit is spaced apart from the transmitting unit to some extent in the closed standby state. Therefore, interference with the transmitter can be avoided. That is, when the receiver is placed near the ear of the caller in the standby state, the transmitter can be placed near the mouth. As a result, it is possible to make a call with a single receiver.
Furthermore, since the same receiver is used, a control means for switching the receiver between the miniaturized standby state and the open state is not required, and the configuration can be simplified.

The swivel mobile phone device of the present invention is configured such that the display unit is a liquid crystal display unit that displays a liquid crystal image on the viewing surface of the second casing,
The flat panel speaker vibrates a transparent panel of the liquid crystal display unit provided on the viewing surface of the upper housing.

  According to such a configuration, since the diaphragm of the flat panel speaker is also used as the transparent panel of the liquid crystal display unit, the installation area can be efficiently saved and the size of the swivel mobile phone device can be reduced. It is suitable for aiming at.

  When the swivel type mobile phone device of the present invention is in a state where the first casing and the second casing are closed with the display unit of the second casing exposed to the outside, Through a through-hole that takes the voice uttered by the speaker into the transmitter of the first housing at a predetermined position of the second housing facing the transmitter of the first housing. It is provided.

  According to such a configuration, the second casing can be configured to have almost the same length as the first casing, and the casing can be reduced in size accordingly.

  According to the present invention, by using the same transmitter and receiver, not only the first and second housings are opened, but also the standby state with the display exposed to the outside can be used. A call is possible. Moreover, by using the same transmitter and receiver together, it is possible to provide a swivel mobile phone device that does not require switching between the receiver used in the open state and the receiver used in the standby state.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a swivel mobile phone according to an embodiment of the present invention. The swivel mobile phone includes a lower housing (first housing) 1 and an upper housing (second housing). Body) 2 and a connecting portion 3, and the upper housing 2 is approximately 180 degrees in the vertical direction (vertical direction with respect to the paper surface of FIG. 1) via the connecting portion 3 with respect to the lower housing 1. At the same time it can be opened and closed in an angle range, it can be rotated in an angle range of 360 degrees (or 180 degrees).

  Among them, the lower housing 1 is provided with an operation unit 11 provided with various key buttons and a transmission unit 12 using a microphone on an operation surface 1A described later, and can be operated even in a miniaturized standby state. Thus, the key buttons 13 are provided separately (one in each case for on-hook and one for off-hook in this embodiment).

  The operation unit 11 is provided with a plurality of various key buttons for inputting various types of information on the operation surface 1A, which is one surface. Among these key buttons, on-hook and off-hook operations for switching between a state in which a call can be made and a state in which a call cannot be made when the upper and lower casings 1 and 2 are opened (the state shown in FIG. 1). A call button is also included.

  On the other hand, the key button 13 is provided in the upper and lower casings 1 and 2 in order to be able to switch between a call-capable state and a call-disabled state by performing an off-hook operation, an on-hook operation, etc. Is provided separately from the above-described call button for switching between a call-enabled state and a call-disabled state in the open state (the state shown in FIG. 1). The key button 13 may be anywhere as long as it is arranged in a portion exposed when the mobile phone is in a standby state, and is not limited to the configuration of the key button 13 that is operated to press as in this embodiment. Various sensors such as a touch sensor may be used.

  On the other hand, the upper housing 2 is provided with a display unit 21, a receiver unit 22, and the like on one viewing surface 2 </ b> A.

  Among them, the display unit (LCD) 21 is configured by a liquid crystal display unit (LCD) using liquid crystal, which protects the liquid crystal display unit (LCD) and is a transparent part of a flat panel speaker described later. A panel portion (hereinafter referred to as “transparent panel”) is provided on the viewing surface 2A of the upper housing 2.

  On the other hand, a (flat) panel speaker is used for the reception unit 22 of the present embodiment. This (flat) panel speaker is of the conventional type that has been the basis of the speaker since Kellogg / Rice invented about 80 years ago, that is, the voice coil in the magnetic circuit moves back and forth to move the cone. This is a completely different configuration from the cone type that converts electrical signals into audio signals, and is called the DM (Distributed mode) type. By analyzing the vibration mode distribution of the diaphragm, the resonance mode ( By flexibly controlling (bending wave), a specific part is vibrated to generate divided vibrations to generate sound. This (flat) panel speaker achieves a significant reduction in thickness and flatness as compared to the cone type, and an improvement in sound quality.

  This (flat) panel speaker is configured so that the transparent panel of the display unit (LCD) 21 is also used as an acoustic diaphragm. The upper casing 2 directly below the transparent panel is provided with a sound emission drive means (driver) 221 that vibrates the transparent panel (acoustic diaphragm) so that the entire transparent panel can emit sound. It is configured.

Further, in the present invention, in addition to the receiver unit 22, another receiver unit having, for example, a ringer or a loudspeaker function may be arranged as an auxiliary, and the transparent panel of the display unit 21 of the upper housing 2 is exposed. In addition to the display unit (LCD) 21, a display unit having a smaller area or the like may be provided on the outer surface 2B opposite to the surface 2A.
In the present embodiment, the receiving unit 22 is configured to use both the display unit (LCD) 21 and a part of the receiving unit 22 such as vibrating the transparent panel of the display unit (LCD) 21. The configuration is not limited.

  The connecting portion 3 is from the state shown in FIG. 3 (closed state) in which the operation surface 1A of the lower housing 1 and the visual recognition surface 2A of the upper housing 2 described above where the various key buttons of the operation portion 11 are installed are closed. FIG. 1 shows an “opening / closing operation” that can be expanded approximately 180 degrees in the vertical direction (a direction along a plane perpendicular to the paper surface of FIG. 1) until the open state as shown in FIG. 1, and from the open state shown in FIG. It is configured by an appropriate mechanism having two rotation axes (two axes) in two directions orthogonal to each other so that a “turning operation” capable of 360-degree turning (may be configured to turn 180 degrees) is possible. ing. In addition, this connection part 3 is comprised so that a standby state can also be set by the operation which makes it rotate about 180 degree | times and makes it close after turning 180 degree | times from the closed state shown in FIG.

  Therefore, even if the housing of the mobile phone is folded compactly, the viewing surface 2A with the display unit 21 of the upper housing 2 can be exposed to the outside, and the display unit 21 of the viewing surface 2A is a (flat) panel speaker. Therefore, the other party's voice can be emitted from here. Furthermore, since the display unit 21 which is a part of the receiver unit 22 is separated from the transmitter unit 12 to some extent, interference with the transmitter unit 12 can be avoided during sound emission.

FIG. 2 shows a swivel mobile phone according to an embodiment of the present invention, in which the upper case 2 is turned 180 degrees from the open state as described above, and the upper and lower cases 1 and 2 are overlapped (closed) in a compact and compact manner. It is a top view which shows the waiting state.
In this standby state, the entire upper and lower casings 1 and 2 are superposed and miniaturized with the viewing surface 2A provided with the receiver 22 exposed, and in particular, the lower end of the operation surface 1A of the lower casing 1 The transmitter 12 arranged close to the transmitter 12 is arranged so as not to be blocked by the upper casing 2 (receiver 22) and exposed to the outside even when the upper and lower casings 1 and 2 are overlapped. Yes.
On the other hand, the receiving unit 22 is composed of the flat panel peaker described above, and is configured so that sound and the like can be heard from the entire transparent panel of the display unit (LCD) 21. The reception unit 22 can be arranged at the position of the ear with the transmitter 12 being arranged near the mouth, even in the open state in which it is largely deployed, or in the standby state in which it is closed and compact.

  Accordingly, even in the standby state in which the upper and lower casings 1 and 2 are gathered together and overlapped as shown in FIG. 2, the key button 13 on the side of the lower casing 1 is operated to perform off-hook and on-hook operations. Calls can be made.

  Of course, even when the upper and lower casings 1 and 2 are opened as shown in FIG. 1, the transmitter 12 corresponds to the position near the mouth and the receiver 22 corresponds to the position of the ear. By using the off-hook and on-hook call buttons provided on the operation unit 11, a call using the transmitter 12 and the receiver 22 can be performed.

  As a result, two modes of the normal open state shown in FIG. 1 and the standby state shown in FIG. 2 can be selected as usage modes when talking with the other party.

  It should be noted that the transmitter 12 of the present embodiment overlaps the entire casing 2 even in a standby state in which the entire casing is overlapped and the viewing surface 2A having the display unit 21 of the upper casing 2 is exposed to the outside. For example, as shown in FIG. 4, a structure may be adopted in which a hole 2 </ b> C for a transmission section that introduces and transmits a transmission sound in the upper housing 2 is opened as shown in FIG. 4. Or it is good also as a structure which has the sound hole for transmission parts near the lower end part of the lower housing | casing 1 side surface.

Moreover, in this embodiment, as the connection part 3, the opening / closing operation | movement rotated to an up-down direction (surface direction perpendicular | vertical to the paper surface of FIG. 1), and the turning operation | movement which makes it turn centering on the rotating shaft outside illustration of the connection part 3 Although a two-axis rotation mechanism capable of performing both of these is used, a single-axis structure that allows only a turning operation that turns around the rotation shaft provided in the connecting portion 3 may be used.
In addition, this invention is not limited to embodiment mentioned above at all, In the range which does not deviate from the summary, it can implement with a various form.

  The swivel mobile phone according to the present invention is capable of making a call not only in the opened state in which the first and second housings are opened, but also in the standby state in which the display unit of the second housing is exposed, and the same. Since the transmitter and receiver can be used, there is no need to switch between the receiver that is used in the open state and the receiver that is used in the standby state, and the first and second casings turn. This is useful for mobile phone devices having a structure of formula.
