 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing a state in which an in-vehicle mount for a mobile phone according to an embodiment of the present invention is attached to a console, FIG. 2 is a perspective view showing a stand of the same embodiment, and FIG. 3 is a perspective view of a main part showing the stand. FIG. 4, FIG. 4 is a block diagram of the voice recorder circuit portion of the same embodiment, FIG. 5 is a flow chart showing a recording / playback operation procedure according to the same embodiment, and FIGS. 6A and 6B show the bracket of the same embodiment, respectively. It is a side view and a front view shown.

A mobile phone vehicle-mounted fixture (hereinafter simply referred to as a fixture) 20 shown in FIG. 1 is composed of a table 21 for mounting the cell phone 10 and a bracket 22 for holding the table 21. For example, it is attached to the center console 23.

As shown in FIGS. 2 and 3, the mounting table 21 has a housing 24, and an arm 25 slidable in the C direction in the drawing (sliding width is D millimeter) is provided in the housing 24. It is installed. The arm 25 is attached to the back surface of the housing 24 and is fixed at a desired position by an accompanying screw 26. The back surface of the housing 24, including the screws 26, has no step, and the screwing is not limited to one place as in the present embodiment, but may be performed at two places. The mobile phone 10 placed on the stand 21 is held by the arm 25. Therefore, even if the width of the mobile phone 10 mounted on the vehicle is different, by adjusting the slide width of the arm 25, the mobile phone of any size can be securely held. The housing 24 and the arm 25 are made of resin, and the telephone installation surface 27 of the housing 24 is coated with protein. Further, "28" is a pad for abutting and firmly holding the mounted mobile phone 10, and the pad 28 is made of, for example, foamed vinyl chloride. Further, “29” is a screw hole for fixing the mounting table 21 to the bracket 22, and a metal nut (not shown) is inserted in the screw hole 29.

The stand 21 also functions as a voice recorder, and has a voice recording / playback function for recording and playing back the voice received by the mobile phone. On the right side (driver's seat side) of the housing 24, in addition to an operation section and a circuit section therefor, a microphone and a speaker for making the mobile phone hands-free are arranged. In other words, it is configured as a voice recorder with an integrated microphone and speaker. By laying out the operation section and the speaker to the driver's seat side in this way, good operability is ensured.

First, the operation unit 30 includes various switches and displays as shown in FIG. The switches are a record (REC) switch 31, a play (PLAY) switch 32, a reset (RESET) switch 33, a start (START) switch 34, a stop (STOP) switch 35, and a volume (VOLUME) switch 36. An up (UP) switch 37, a down (DOWN) switch 38, and a power switch (not shown). The method of operating these switches will be described later. In addition, as a display, a recording (REC) LED 39, a reproducing (PLAY) LED 40, an in-operation (OPERATE) LED 41, and a power supply LED 42 are provided. The recording LED 39 is red, the reproducing LED 40 is green, the operating LED 41 is yellow, and the power LED 42 is red. Further, "43" and "44" are holes for the built-in microphone and the built-in speaker, respectively.

The layout of the operation unit 30 of this embodiment is as described above, but it goes without saying that the layout is not limited to this. Further, in this embodiment, the button type is used as the volume switch 36, but of course the dial type may be used.

Inside the operation unit 30, a circuit board for a voice recording / reproducing circuit, a switch circuit, a display circuit, etc., a microphone, a speaker, a backup battery (not shown), etc. are accommodated. A block diagram of such a voice recorder circuit unit is shown in FIG. As shown in the figure, the voice recorder circuit unit 45 includes a microphone 46, a speaker 47, an echo canceling circuit 48 for preventing howling of the speaker 47, and an earphone signal output from the mobile phone 10. A voice recording / playback circuit 49 for inputting a voice signal from the microphone or the microphone 46 to record and play back a call voice, and an automatic volume control circuit 50 for automatically adjusting the volume level to an optimum value according to the noise level. In this embodiment, the earphone microphone terminal 51 of the mobile phone 10 is used, and the mobile phone 10 and the voice recorder 45 can be connected in a circuit manner via the earphone microphone terminal 51. The earphone microphone terminal 51 of the mobile phone 10 is connected to the echo canceling section 48 in the voice recorder circuit section 45 by a coaxial pin jack. The microphone 46 is omnidirectional with the same sensitivity in all directions, and can pick up the voice of the caller regardless of where and in which position the passenger compartment is mounted. The microphone 46 is connected to the echo canceller 48. In order to prevent howling, the voice signal processed by the echo canceller 48 is branched into two, one of which is input to the voice recording / reproducing circuit 49, and the other of which is a changeover switch 52 for enabling a hands-free call. It is directly input to the automatic volume control circuit 50 via. The voice recording / reproducing circuit 49 is composed of a voice IC (for example, Toshiba's voice IC TC8832F), inputs a voice signal to record a voice in the IC, and outputs a recorded voice signal during reproduction. The changeover switch 52 is internally changed over in conjunction with the recording switch 31 and the reproduction switch 32. That is, when the recording switch 31 is pressed, the terminal A is closed and the terminal B is opened to enable the hands-free call, while when the reproduction switch 32 is pressed, the terminal A is opened and the terminal B is reversed. The switching is controlled to close. The automatic volume control circuit 50 is connected to the echo canceling circuit 48, detects the level of the low frequency noise picked up by the microphone 46, and automatically adjusts the output volume level to an optimum value that is easy to hear. For example, increase the volume to a level where it is easy to hear when the noise is loud, and set the volume to a normal level when the noise is low. The sound whose volume is adjusted by the automatic volume control circuit 50 is output from the speaker 47 through the amplification amplifier 53. Further, “54”, “55” and “56” are variable resistors, and the variable resistors 54 and 55 prevent an uncomfortable feeling at the time of switching due to a difference in volume between a hand-free call and voice reproduction. This is for adjusting the level of the signal output directly from the erasing circuit 48 to the automatic volume control circuit 50 and the level of the output signal of the voice recording / reproducing circuit 49 to be the same. Further, the variable resistor 56 is for finely adjusting the level of the audio signal according to preference. As described above, in this embodiment, the voice recorder circuit unit 45 including the microphone 46 and the speaker 47 is all built in the housing 24 of the stand 21. With such a configuration, it becomes possible to make a call (hands-free call) between the microphone 46 and the speaker 47 without using the mobile phone 10, and at the same time while making this hands-free call. The voice of the other party can be recorded on the IC.

The procedure of the recording / playback operation in the mobile phone voice recorder thus configured is as shown in the flowchart of FIG. First, a power switch (not shown) is turned on (S1). As a result, the power supply LED 42 is turned on (S2). If you want to record a call, press the record switch 31 to connect the changeover switch 52 to the recording side, that is, to the terminal B. If you want to reproduce the recorded content, press the reproduction switch 32 to move the changeover switch 52 to the reproduction side, that is, the terminal A. Connect to. When it is determined that the changeover switch 52 is on the recording side (S3), that is, when the recording switch 31 is pressed, the recording LED 39 is turned on (S4), and the reset switch 33 is pressed (S5). When the start switch 34 is further pressed (S6), the operating LED 41 lights up (S7) and recording starts (S8). After that, when the stop switch 35 is pressed (S9), the operating LED 41 is turned off (S11), the recording is stopped (S12), and the process returns to step 3. If it is determined that the memory in the voice recording / playback circuit 49 is completed without pressing the stop switch 35 (S10), the process proceeds to step 11 to stop the recording operation.

On the other hand, when it is determined in step 3 that the changeover switch 52 is on the reproducing side, that is, when the reproducing switch 32 is pressed, the reproducing LED 40 lights up (S13), and the start switch 34 is further pressed (S14). ), The operating LED 41 lights up (S15) and the reproduction is started (S16). When the start switch 34 is pressed during reproduction (S17), the operating LED 41 is immediately turned off (S24), reproduction is stopped (S25), and the process returns to step 3. On the other hand, when the stop switch 35 is pressed (S18), it is temporarily stopped (S19), and when the stop switch 35 is further pressed (S20), the process proceeds to step 24 to completely stop the reproduction operation. When the start switch 34 is pressed instead of the stop switch 35 (S21), the reproduction is continuously started from the state before the stop (S22), and the process returns to step 17. Further, even if the start switch 34 or the stop switch 35 is not pressed during the reproduction, when the memory in the voice recording / reproducing circuit 49 is finished (S23), the process proceeds to step 24 and the reproducing operation is stopped.

In addition to the recording / playback of the voice as described above, when the recorded voice is desired to be erased, the reset switch 33 is pressed. The volume output 36 adjusts the audio output.

As shown in FIGS. 6 (A) and 6 (B), the bracket 22 is composed of a mounting base mounting portion 57 for mounting the mounting base 21 of the mobile phone 10 and a leg portion 58 for sandwiching the center console 23. ing. Bolt through holes 59 for attaching the mounting table 21 to the bracket 22 are formed on the surface of the mounting table mounting portion 57 so as to correspond to the screw holes 29 on the back surface of the mounting table 21. Further, the table mounting portion 57 is pivotable in the E direction in the figure, and the angle can be freely adjusted. The table mounting portion 57 adjusted to a desired angle is fixed by a bolt 60 and a nut 61. On the other hand, the leg portion 58 is composed of an upper support frame 62 and a lower plate 63, both of which are connected to a long hole 64 provided in the lower plate 63 by a bolt 65 penetrating therethrough. Therefore, the leg portion 58 can be freely expanded and contracted in the F direction in the figure, and its height can be adjusted. The leg portion 58 adjusted to a desired height is fixed by a bolt 67 and a nut 68 in a state in which the center console 23 is sandwiched together with the contact plate 66. Urethane 70, for example, is laid on the inside of the lower plate 64 and the inside of the contact plate 69 below the support frame 62 to protect the surface of the center console 23.

An example of a procedure for attaching the mobile phone 10 to the center console 23 using the attachment 20 of the present embodiment having the above-described configuration is as follows. First, the mounting table 21 is attached to the mounting table mounting portion 57 of the bracket 22 using bolts. Next, the center console 23 is sandwiched between the lower plate 63 of the leg portion 58 of the bracket 22 and the contact plate 69, the height of the leg portion 58 is adjusted according to the height of the center console 23, and the bolt 67 is applied. The plate 66, the abutting plate 69, and the through hole 64 of the lower plate 63 are respectively inserted, and the nuts 68 are screwed and fixed, so that the fixture 20 is attached to the center console 23. Then, adjust the angle of the stand mounting portion 57 of the bracket 22 according to the operability when sitting in the driver's seat, and fix it with the bolt 60 and the nut 61 at the angle of your choice. Then, the mobile phone 10 is placed on the stand 21, the arm 25 is slid according to the width of the mobile phone 10, and the arm 25 is fixed by the screw 26. As a result, the mobile phone 10 is firmly held on the stand 21. It should be noted that this procedure is merely an example, and it is needless to say that the procedure can be attached by any other suitable procedure.

Therefore, according to the present embodiment, the stand 21 of the mobile phone 10 is provided with a voice recording / playback function, and the microphone 46 and the speaker 47 are built in to form an integrated voice recorder. While trying to be hands-free, when you are making a hands-free call in the vehicle and you want to make a note of the other party's requirements, you can record the voice on the IC with a simple switch operation and play it back later. Then, it becomes possible to check the contents slowly, which greatly improves the convenience of the mobile phone mounted in the vehicle. In addition, in order to enjoy the hands-free operation with such a voice recording / playback function, the earphone microphone terminal 51 of the mobile phone 10 is simply used without any special modification to the mobile phone 10. Does not impair the portability of mobile phones. Further, since the microphone 46 is omnidirectional and the operation unit 30 such as a switch and the speaker 44 are arranged on the driver's side, workability at the time of mounting and operability at the time of use are improved.

Further, since the mobile phone 10 can be attached to the center console 23 by using this attachment 20 and is close to the shift lever, the operation within the reach of the vehicle can be performed without damaging the living space in the vehicle interior. Mobile phones can now be installed in locations that are easy to access, which makes effective use of the vehicle interior space and improves operability. The ability to freely adjust the mount mounting portion 57 of the bracket 22 to a desired angle also contributes to improved operability.

Further, in the present embodiment, the stand 21 can be adjusted to the width of the mobile phone 10 by sliding the arm 25, so that the mobile phone of any size can be mounted. Also, with respect to the bracket 22, the height of the legs 58 can be adjusted to match the height of the center console, so that the bracket 22 can be used regardless of the vehicle type. Therefore, the fixture 20 has high versatility in that it can be used even if the type of mobile phone or the type of vehicle is different.

In addition, in the present embodiment, the case of attaching to the center console has been described, but it goes without saying that the attaching place is not limited to this. By changing the shape of the bracket, it can be mounted in any suitable place. For example, it can be mounted on the lid of the console box.
