FIG. 5 is an external perspective view in which a mobile phone 6, which is an example of a portable electronic device, is attached to the charger 1, and FIG. 6 is an acoustic device that includes the mobile phone 6 and the charger 1. It is a block diagram which shows a structure. FIG. 1B is a cross-sectional view taken along line bb in FIG.

  As shown in FIGS. 1A, 1B, and 6, the charger 1 has a box-shaped housing 3 having a space inside, and an inner surface x and a depth p are formed on the upper surface 3a. The main body part 3f in which the circular recessed part 3b which it has was formed, and the concave mounting part 5 (equipment mounting part) which can mount the mobile telephone 6 to the front side (left side in FIG.1 (b)) of the housing | casing 3 are comprised. . In addition, a power input unit 7 configured to be able to input power supplied from an external power source, and a portable device in which power from the external power source is mounted on the mounting unit 5 via the power input unit 7 by an electrical connection structure (not shown). The power output unit 8 configured to be able to supply power to the battery 68 provided in the telephone 6 and the electric connection structure connected to the external connection unit 70 provided in the mobile phone 6 described later is output from the mobile phone 6. And an amplifier 9 that amplifies the acoustic signal and is connected to the speaker 4.

  In addition, the stepped surface (bottom surface) of the recess 3b formed in the main body 3f is formed with a circular opening 3d having a diameter y that allows the inside and the outside of the main body 3f to communicate with each other. It is attached inside the main body 3f so that the surface is exposed from the opening 3d.

  A speaker cover 2 that can be inserted into the recess 3b is attached to face the opening 3d. Further, a magnet sheet 3e (magnet) is attached to a portion of the bottom surface portion 3c where the opening 3d is not formed.

  As shown in FIG. 3, the speaker cover 2 has a cylindrical portion 2a formed in a cylindrical shape having an outer diameter z, and the inner space of the cylindrical portion 2a is substantially in the cylindrical axis direction. An inner wall portion 2b divided in half is disposed. The inner wall 2b is formed in a conical shape at the center and a hole 2c is formed at the tip. In addition, a plurality of cutout portions 2d having a cutout height q are formed at one end portion of the cylindrical portion 2a on the side opposite to the side where the tip of the cone is located (four in FIG. 3). This notch height q is configured to be longer than the depth p of the recess 3 b formed in the main body 3 f of the housing 3. In addition, the one end part and other end part of the cylindrical part 2a are formed with the magnet.

  Further, since the outer diameter z of the cylindrical portion 2a of the speaker cover 2 is smaller than the inner diameter x of the recess 3b formed in the housing 3 and larger than the diameter y of the opening 3d, the speaker The cover 2 has one end portion (one of attachment portions) of the cylindrical portion 2ab in which the cutout portion 2d is formed and the other end portion (one of attachment portions) of the cylindrical portion 2ac in which the cutout portion 2c is not formed. Each of the recesses 3b can be inserted into the recess 3b. In each insertion state, one end or the other end of the cylindrical portion 2a of the speaker cover 2 formed of magnets and the magnet sheet 3e attached to the bottom surface portion 3c attract each other by magnetic force. The speaker cover 2 can be easily and reliably attached to the main body 3f.

  Here, in the speaker cover 2, the cylindrical part 2ab in which the notch 2d is formed is inserted into the recess 3b as a first mounting state (shown in FIG. 1), and the cylindrical part in which the notch 2d is not formed. A state in which 2ac is inserted into the recess 3b is defined as a second mounting state (shown in FIG. 2). Then, the state in which the speaker cover 2 is removed from the housing 3 is set to the detached state (shown in FIG. 4).

  Since the height q of the notch 2d is longer than the depth p of the recess 3b formed in the housing 3 as described above, a part of the notch 2d is outward in the first mounting state. The exposed inside of the cylindrical portion 2ab and the outside of the housing 3 are communicated with each other. Further, the inside of the cylindrical portion 2ab side and the outside of the housing 3 are also communicated with each other by a hole 2c formed at the conical tip of the inner wall 2b. Therefore, in the first wearing state, the sound from the speaker 4 is output to the outside through the notch 2d and the hole 2c.

  Further, in the second mounting state, the cylindrical portion 2ac of the speaker cover 2 has no notch 2d, so that the inside of the cylindrical portion 2ac side and the outside of the housing 3 are at the conical tip of the inner wall portion 2b of the speaker cover 2. It will be connected only by the formed hole 2c. Therefore, in the second wearing state, the sound from the speaker 4 is output to the outside through the hole 2c.

  Next, the configuration of the mobile phone 6 will be described. As shown in the block diagram of FIG. 6, the mobile phone 6 includes a display device 61, a built-in antenna 62, a receiving speaker 63, and a notification speaker 64 (sound output unit). A rectangular first housing 6a, an operation unit 65, a transmission microphone 66, a control unit 67 (acoustic signal control unit), a battery 68, a communication unit 69, and an external connection unit 70 are provided. And a second housing 6b having the same rectangular shape. Although not shown, the housings 6a and 6b are opposed to each other with the display device 61 and the operation unit 65 facing each other, and the closed state in which the notification speaker 64 is exposed, the display device 61 and the operation unit 65, Are connected to each other in a foldable manner so as to be switched through an unshown hinge portion.

  Here, the display device 61 is a liquid crystal panel, for example, and can display various information such as the current time and input information. The built-in antenna 62 is a conventionally known built-in antenna, and is configured to be able to transmit and receive electromagnetic waves of information related to communications such as telephone calls and text messages in a predetermined frequency band. The receiving speaker 63 is a speaker that outputs a sound corresponding to a signal related to the voice of the communication partner related to the telephone. The notification speaker 64 is a speaker that outputs a sound corresponding to an acoustic signal related to a ring tone, a ring melody, a voice, or the like. The operation unit 65 is an input unit of the mobile phone 6 and is configured to include a plurality of buttons such as a numeric keypad, and the user can perform various input operations by operating these buttons. The transmitting microphone 66 is a microphone for inputting user's voice and the like in a telephone. The battery 68 is, for example, a lithium ion battery, and is configured to be rechargeable by being supplied with power from an external power supply via the power output unit 8 of the charger 1 described above, and the charged power is controlled by the control unit. 67 can be supplied with power. The communication unit 69 performs control related to communication such as telephone and text message transmission / reception performed via the built-in antenna 62. The external connection unit 70 is a connection terminal for outputting an acoustic signal, which is disposed so as to be exposed to the outside of the second housing 6b.

  The control unit 67 (acoustic signal control unit) performs various controls of the mobile phone 6 based on the electric power supplied from the battery 68. For example, display control of various information on the display device 61, the receiving speaker 63, Sound notification control through the notification speaker 64, operation control based on various input operations through the operation unit 65, input control of voice input through the transmission microphone 66, and the like are performed. In addition, external output control for outputting an acoustic signal to an external device can also be performed. For example, for the amplifier 9 of the charger 1 connected by the electrical connection structure connected to the mobile phone 6 and the external connection unit 70. An acoustic signal can be output.

  FIG. 5 is a diagram showing a state in which the mobile phone 6 is attached to the attachment portion 5 of the charger 1, and the charger 1 and the mobile phone 6 constitute an acoustic device 10. As shown in the figure, the mobile phone 6 can be mounted on the mounting portion 5 in the above-described closed state, and is supported by a mobile phone support portion (not shown) provided on the mounting portion 5 in this mounted state. Is done. In the state in which the cellular phone 6 is inserted into the mounting portion 5, the electric power output portion 8 and the battery 68 are connected to each other, and the amplifier 9 and the control portion 67 are connected to the external connection portion 70. Are electrically connected to each other. In the state where the mobile phone 6 is mounted on the mounting portion 5 in this way, the notification speaker 64 of the mobile phone 6 faces the front side of the housing 3 as shown in FIG.

  Hereinafter, a report sound form when sound is output from the speaker 4 of the charger 1 will be specifically described with reference to FIGS. 7 to 9. When the mobile phone 6 is attached to the attachment unit 5, the amplifier 9 of the charger 1 and the control unit 67 of the mobile phone 6 are electrically connected to each other by an electrical connection structure. In this state, when the control unit 67 performs external output control and outputs an acoustic signal to the amplifier 9 at the time of music playback by the music playback function or notification at the time of incoming call, the speaker 4 outputs a sound based on the acoustic signal. Can be output.

  Then, in the first wearing state of the speaker cover 2 shown in FIG. 7, when incoming calls such as a telephone (voice communication) or text message via the built-in antenna 62 are performed by the communication unit 69, the notification speaker 64 is controlled. The sound signal of the ring tone related to the ring tone, the ring melody, and the voice is output by the notification control of the unit 67, and the sound signal is output from the external connection unit 70, the electrical connection structure, The signal is output to the speaker 4 through the amplifier 9. The speaker 4 and the notification speaker 64 output ringtones, incoming melody, voice and the like based on the output acoustic signals.

  Since the speaker cover 2 is attached to the housing 3 in the first wearing state at a position facing the sound output surface, the speaker 4 outputs the sound output from the speaker 4 in the first wearing state. Sound is emitted through the cover 2. That is, the sound output from the speaker 4 is output in the upper direction of the housing 3 through the hole 2c formed in the speaker cover 2, and is output in the horizontal direction of the housing 3 through the notch 2d. Is done. As described above, the sound output from the speaker 4 to the outside is output in the upper side direction (substantially vertical direction) of the housing 3 and the lateral side direction (substantially horizontal direction) of the housing 3 through the speaker cover 2. The user can clearly hear the sound output from the speaker 4 by being narrowed down in multiple directions.

  Here, as described above, the portion of the speaker cover 2 that contributes to the change in the sound output form of the sound output from the speaker 4, that is, the hole 2c and the notch 2d formed in the speaker cover 2, the cylindrical portion 2ab, and the inner wall The parts constituted by the part 2b are collectively referred to as a sound report form changing part.

  Further, since the speaker cover 2 in the first mounted state is only attached by the magnetic force of the magnet sheet 3e attached on the recess 3b, it can be rotated while being attached to the recess 3b ( Of course, it can be removed once and attached in another direction.) That is, the direction in which the notch 2d of the speaker cover 2 faces can be adjusted to an arbitrary direction. Then, the facing direction of the notch portion 2d can be adjusted to the same direction as the facing direction of the notification speaker 64 of the mobile phone 6 attached to the mounting portion 5 (the forward direction of the housing 3). For this reason, the sound output through the notch 2d and the sound output by the notification speaker 64 can be in the same direction and can be strengthened each other. In such a state, the sound is output in the same direction. The user who is present can hear the sound output from these more clearly.

  On the other hand, the speaker cover 2 in the second wearing state shown in FIG. 8 is controlled when the communication unit 69 performs an incoming call process such as a telephone call or text message via the built-in antenna 62, as in the first wearing state. The sound corresponding to the sound signal related to the incoming call notification such as the incoming call tone or the incoming melody is output to the notification speaker 64 by the notification control of the unit 67. The acoustic signal is connected to the amplifier 9 through an electrical connection structure connected to the external connection unit 70 by external output control of the control unit 67, and then output to the speaker 4. The speaker 4 and the notification speaker 64 output sounds such as ringtones, ringtones, and voices based on the sound signals output in this way.

  Since the speaker cover 2 is attached to the housing 3 in the second mounting state at a position facing the sound output surface, the speaker 4 outputs the sound output from the speaker 4 in the second mounting state. Sound is reported through the cover 2. That is, the sound output from the speaker 4 is output only in the upward direction (substantially vertical direction) of the housing 3 through the hole 2c.

  As described above, the sound output form of the sound output from the speaker 4 in the second wearing state is different from that in the first wearing state, and the sound output from the speaker 4 is transmitted to the upper side of the housing 3 via the speaker cover 2. Since the sound is output only in the direction, the user can clearly hear the sound output from the speaker 4 in a manner different from that when the speaker cover 2 is in the first wearing state.

  Note that the notification speaker 64 of the mobile phone 6 and the speaker 4 of the charger 1 have different sound output directions to output different sounds according to the respective output directions. For example, the user can enjoy a sound with a sense of stereo by outputting the sound in the high sound region from the notification speaker 64 and outputting the sound in the middle and low sound region from the speaker 4.

  In addition, since the speaker cover 2 is configured to be detachable from the housing 3, the user can also remove the speaker cover 2. In this state, the speaker cover 2 is output from the charger 1. You can enjoy the sound. FIG. 8 is a diagram showing a report sound form in this case.

  Even in the detached state, as in the first wearing state and the second wearing state, the mobile phone 6 performs control when incoming calls such as calls and text messages via the built-in antenna 62 are performed by the communication unit 67. By the notification control of the unit 67, a sound corresponding to an acoustic signal related to a ringtone, a ringing melody, or the like is output to the notification speaker 64. The acoustic signal is connected to the amplifier 9 through an electrical connection structure connected to the external connection unit 70 by external output control of the control unit 67, and then output to the speaker 4.

  The sound output from the speaker 4 in various directions is output in various directions without being narrowed or absorbed by the speaker cover 4 since the speaker cover 2 is not attached to the housing 3. Is done. That is, in this detached state, the user can enjoy a wider sound.

  As described above, the charger 1 according to the present embodiment can attach the speaker cover 4 to the housing 3 in either the first wearing state or the second wearing state, and put the speaker cover 2 in a detached state. It is also possible to change the sound report form of the speaker 4 by arbitrarily changing the mounting state of the speaker cover 4. Therefore, the user can enjoy the sound output in a plurality of modes without preparing a plurality of speakers.

  Further, since the speaker cover 2 has a plurality of attachment portions for the charger 1, for example, even when one of the plurality of attachment portions is damaged or scratched due to a drop, an impact, or the like, The secondary effect that it can be attached to the charger 1 and can be used for a longer time than the conventional speaker device provided with the speaker cover having only one attachment portion can also be obtained.

  Further, the mobile phone 6 can be attached to the attachment portion 5 of the charger 1, and the acoustic device 10 constituted by the charger 1 and the mobile phone 6 includes a notification speaker 64 provided on the mobile phone 6. Since it is configured to be able to output sound from both the speakers 4 of the charger 1, the sound output from the speakers 4 is changed according to the attachment state of the speaker cover 2, and the sound output in a predetermined direction Can be emphasized, the stereo effect can be improved, or a broad sound can be output.

  In addition, this embodiment is an example of this invention and is not limited to this, A various change is possible. For example, the speaker cover 2 in the present embodiment is configured by being attached by a magnetic force between the magnet sheet 3e attached to the housing 3 and one end and the other end of the speaker cover 2 formed of magnets. However, the present invention is not limited to this. For example, at least one of the housing 3 and the speaker cover 2 may include a magnet, and the speaker cover 2 may be attached to the housing 3 by the magnetic force of the magnet. Good. In short, it is sufficient if both are attached by magnetic force.

  In the present embodiment, the speaker cover 2 is configured to be attached to the charger 1 by the magnetic force of the magnet. However, the mounting structure of the two in the present invention is not limited to this, and for example, the charger 1 A claw portion may be provided on one of the speaker cover 2 and a receiving portion engageable with the claw portion on the other, and both may be configured to be attachable to each other in a plurality of modes. In short, both configurations can be attached to each other in a plurality of modes, and other configurations can be used as long as the configuration can output the sound output from the speaker 2 in different directions in each mode. Good.

  Further, the shape of the recess 3b and the speaker cover 2 formed in the housing 3 is not limited to the cylindrical shape, and the shape of the opening 3d communicating with the inside of the housing 3 formed in the bottom surface portion 3c of the recess 3b is also circular. However, other shapes may be used.

  In the embodiment described above, since the central portion of the inner wall 2b of the speaker cover 2 is formed in a conical shape, the distance from the speaker 4 to the hole 2a formed in the speaker cover 2 in the first wearing state is the second. The distance from the speaker 4 in the mounted state to the hole 2a formed in the speaker cover 2 is far, and thus the output region and volume of the output sound from the speaker 4 output from the hole 2a in the first wearing state Is smaller than the output area and volume of the output sound from the speaker 4 output from the hole 2a in the second wearing state. That is, depending on the mounting state of the speaker cover 2, the distance from the speaker 4 to the hole 2a formed in the speaker cover 2 is also changed, and the output area and volume of the output sound from the speaker 4 output from the hole 2a Will also be changed.

  In view of this, in the present embodiment, the central portion of the inner wall 2b of the speaker cover 2 has a conical shape. However, if the shape is changed to another shape, from the speaker 4 to the hole 2a formed in the speaker cover 2. , And the like, the output area from the speaker 4 and the volume of the output sound output from the hole 2a can be changed.

In the present embodiment, the sound output from the notification speaker 64 of the mobile phone and the sound output from the speaker 4 of the charger 1 are sounds related to the same acoustic signal. However, in the case where the sound signal is configured to be divided into, for example, a stereo left channel sound signal and a stereo right channel sound signal, the control unit 67 of the mobile phone 6 is either The sound based on the sound signal related to the other channel is controlled to be output to the notification speaker 64 and the sound based on the sound signal related to one of the other channels is output to the speaker 4. It is good also as a structure which outputs a sound based on the acoustic signal which concerns on the channel made. With such a configuration, the stereo feeling of the sound output from the acoustic device 10 can be further improved.

  In the present embodiment, the mobile phone 6 is shown as an example of the mobile electronic device. However, the present invention is not limited to this, and the mobile electronic device other than the mobile phone, for example, a portable CD player, a portable DVD player, Other devices may be used as long as they are portable electronic devices capable of outputting sound, such as PDAs (Personal Digital Assistance) and notebook personal computers.
