Description

  The present invention relates to a speaker-equipped mobile device in which measures for increasing the acoustic stereo effect by two speakers are taken.

  As a prior example, as a means for placing a laptop display screen or the like in an upright posture, an accessory having left and right side portions connected to a panel via folding lines has been proposed (for example, Patent Documents). 1). The accessory of this patent document 1 can be made independent by opening the left and right sides of the panel with the display screen open to the left and right of the panel. In another prior example, it has been proposed that a keyboard with built-in speakers at both left and right ends is attached to the back of the information device when it is not needed, so that the speaker is directed forward from the left and right sides of the information device ( For example, see Patent Document 2). In still another preceding example, the left and right speakers are attached to the left and right sides of an electronic device such as an audio player, a mobile phone, or a laptop computer so that the left and right speakers can be turned into independent electronic devices. It has been proposed to project on the side of the electronic device or store it on the back of the electronic device (see, for example, Patent Document 3). In addition, in an information processing apparatus such as a personal computer, it has also been proposed to use a display panel, a pedestal, a decorative panel of a support, a cover, etc. as an acoustic reflector in order to improve the sound quality of a speaker (for example, a patent) Reference 4). In yet another preceding example, two speakers are assembled in a band of a communication device that can be worn on a person's arm, and the directivity direction of the two speakers is expanded by opening the bunt of the communication device.

  By the way, in a mobile device used as an AV viewing terminal, when used on a desk top or floor surface, the mobile device is placed on the desk top surface or floor surface, or placed in a standing posture leaning on a stand. Has been done.

  Therefore, considering the case where the mobile device is stood on the stand and used in a standing posture, it is desirable that the housing itself be provided with the stand. When used as a viewing terminal, it is convenient because the inconvenience of preparing a separate stand or preparing another stand substitute is eliminated. In addition, in the case where speakers are assembled on both the left and right sides of the mobile device housing, a certain stereo effect can be obtained by these speakers, but the size of the mobile device itself is small, so the interval between the left and right speakers is increased. There is a limit to improving the stereo effect.

  On the other hand, since the accessory of the above-mentioned Patent Document 1 is separate from the display screen and is used by attaching the display screen to the accessory only when necessary, the above-mentioned separate stand is prepared. It is no different from the case of preparing a stand substitute.

  Patent Document 2 is applicable to a mobile device that does not have a keyboard because a speaker is attached to the keyboard, for example, a mobile device that has operation buttons on a screen panel such as a photo frame. I can't. Furthermore, in the thing of patent document 3, since it is what attached the speaker to the electronic device provided with independence in a folding type, even if it attaches a speaker with the same structure to the mobile device which does not have independence, the above-mentioned There is a need to prepare a separate stand or a stand substitute. In addition, although it can be said that the thing of patent document 4 is useful in order to improve the sound quality of a deep bass, the effect from a viewpoint of improving a stereo effect cannot be anticipated so much. Moreover, the thing of patent document 5 cannot be applied to the mobile machine which is not provided with the band with which a person's arm is equipped.

  Therefore, as a result of intensive investigations, the inventor of the present application has the convenience of a mobile device that can be used in an upright position on a desk or floor as an AV viewing terminal if a stand is provided on the housing itself. The stand is used not only to stand the housing upright and hold it in a standing position, but also to increase the acoustic stereo effect of the two speakers. If it was possible, the acoustic performance of the mobile device would be improved and the present invention was completed.

  The present invention has been made under the above circumstances, and by providing a stand on the housing itself, not only can the convenience in the state of use in which the mobile device is erected be improved, but the stand is used. Accordingly, an object of the present invention is to provide a speaker-equipped mobile device that can improve the acoustic stereo effect of two speakers.

  The speaker-equipped mobile device according to the present invention is a speaker-equipped mobile device having two speakers, wherein the mobile device housing is provided with a stand for supporting the housing in a standing posture, and the two speakers are provided on the stand. When the two speakers are attached to the stand at a distance from each other, and the mounting posture of the two speakers to the stand supports the housing by the stand and keeps the standing posture, the left speaker of the two speakers Is directed to the front outside the left end of the housing, and the right speaker is directed to the front outside the right end of the housing.

  When this configuration is adopted, the stand provided in the housing can be used immediately for leaning the housing, so use a separate stand or other stand substitute for leaning the mobile device. It becomes possible to enjoy watching AV. When the two speakers are attached to the stand at a distance from each other on the left and right, and the mounting posture of the two speakers with respect to the stand is maintained in the standing posture while supporting the housing by the stand. Furthermore, the left speaker of the two speakers is directed to the front outside the left end of the housing, and the right speaker is directed to the front outside the right end of the housing. Compared to directly viewing the sound of speakers installed on the left and right, the sound can be heard from a wide range on the left and right, and the stereo effect during viewing is improved accordingly.

  In the present invention, the stand is housed in a housing accommodated in a recess formed in the housing, and a housing support posture that protrudes toward the back side of the housing outside the recess and supports the housing; It is desirable that it is attached so that it can be withdrawn between. With this configuration, when carrying the mobile device or placing the mobile device on a desk top surface or a floor surface in a lying posture, the stand can be set in the housing storage posture. Since the stand is stored in the recess of the housing, the stand does not get in the way when the mobile phone is carried. In addition, when enjoying viewing with the mobile device, there is a convenience that the stand can be held in a housing support posture and the mobile device can be stood and held in a standing posture.

  In the present invention, the stand is provided by a pair of left and right plate-like members attached to the housing so as to be swingable between the housing housing posture and the housing supporting posture with a location near the center of the housing as a fulcrum. The left speaker is built in the free end of the left plate-like member, and the right speaker is built in the free end of the right plate-like member. It is possible. With this configuration, since the stand is formed by a pair of left and right plate-like members, the recess provided in the housing for storing the stand can be a narrow space. Therefore, even if the stand is provided in the housing, there is an advantage that the mobile device is not enlarged.

  In the present invention, the housing is provided with a sound hole duct that guides the sound of the speaker attached to the left plate-like member in the housing housing posture to the left side of the housing, and the right side of the housing housing posture. It is desirable to employ a configuration in which a sound hole duct is provided to guide the sound of the speaker attached to the plate-like member to the right side of the housing. With this configuration, when the left and right plate-like members are in the housing retracted position, the sound emitted from the speakers incorporated in them is guided to the left side or right side of the housing through the sound hole duct. Therefore, it is difficult for the sound of the speaker to squeeze into the housing, and the effect of spreading the sound to the left and right is improved as compared with the case where the speakers are mounted forward on the left and right of the housing. Therefore, even when the mobile device is placed on a desk surface or a floor surface in a lying posture to enjoy viewing, the stereo effect by the two speakers is increased.

  According to the present invention, since the housing itself includes the stand, convenience when the mobile device is used in a standing posture is improved. Further, when the stand is used as an installation member for two speakers and the housing is supported by the stand and kept in an upright position, the sounds of the two left and right speakers spread toward the left end of the housing and the diagonally forward front of the right side. Since the configuration is adopted, an effect that the acoustic stereo effect by the two speakers is increased is obtained as compared with the case where the speakers are merely provided on the left and right sides of the housing. In the case where the sound hole duct is provided in the housing, the stereo effect by the two speakers is increased even when the mobile device is placed on the desk top surface or the floor surface in a lying posture to enjoy viewing. Furthermore, even a mobile device that does not include a keyboard such as a desktop photo frame can increase the acoustic stereo effect.
