received from the other party, and an end button unit 15 for ending the state of an incoming /
outgoing call are provided.
[0019]
2 is a plan view showing the receiving matrix forming unit 11, FIG. 3 is a sectional view when the
button switch unit of the receiving matrix forming unit 11 is in the OFF state, and FIG. 4 is a
button switching unit of the receiving matrix forming unit 11 in the ON state Is a cross-sectional
view of FIG.
[0020]
The receiving matrix construction unit 11 is provided with a wall 23 made of a light impermeable
insulating resin material evenly divided in a 5 × 5 mass, and is separated by a wall 23 made of a
light impermeable insulating resin material. A flat speaker (sound generation means) 21 and an

The flat speaker / infrared sensor control board (control unit) 25 of FIG. 3 is disposed in a space
divided by the wall 23 of the light impermeable insulating resin material evenly divided into 5 ×
5 squares in FIG. The infrared sensor 22 irradiates the user's ear with infrared light, and detects
that the reflection time is the slowest among the reflections of the irradiation within a
predetermined time range as near the ear canal.
The connection progress sound and the call sound are generated only for the flat speaker 21
directly below the detected infrared sensor 22.
It is possible to detect the position of the ear canal in real time in accordance with the movement
of the ear canal, and to change the amount of generation of the individual flat speakers 21.
[0023]
Directly over the 5 × 5 grid with the flat speaker 21 that outputs connection progress sound and
call sound, and the infrared sensor 22 placed directly above it, a mesh plastic material with high
light transmittance is covered and pressed The reception matrix construction unit 11 integrally
formed with the button SW 24 is constructed.
[0024]
As described above, an example of the operation of the reception matrix construction unit in
outgoing / calling using a simple phone will be described.
First, an example of transmission will be described.
[0025]
In order to permit the calling operation after the user has entered the telephone number of the
other party to be called by the dial input button section 13.
The start button unit 14 is pressed.
09-05-2019

After pressing the start button unit 14, the user's ear is pressed against the reception matrix
forming unit 11, and the push button SW24 of FIG. 4 is pressed from the state where the push
button SW24 of FIG. The infrared sensor 22 starts infrared radiation.
Then, by the time the other party answers, a connection progress sound that is in the middle of
connection starts to be generated. At this time, if the user's external ear canal has not been
detected yet, all of the flat speakers 21 will sound.
[0026]
The infrared sensor 22 emits infrared light in a range of a predetermined time, and receives
reflected light for the irradiation. The flat speaker / infrared sensor control board unit 25 counts
the time from the irradiation to the reception of the reflected light. When the infrared sensor 22
determines that the reflection time is the slowest, it determines that the user's ear canal is at the
position of the infrared sensor 22, and the flat speaker / infrared sensor control board unit 25
receives the light reception time. The connection-progressive sound is generated only from the
flat speaker 21 in the reception matrix constructing unit 11 which is directly below the infrared
sensor which has the longest length. Conversely, if it is determined that there is no reflection to
radiation within a certain fixed time range, or if the push button SW24 is pressed as shown in
FIG. 4 from the state where the push button SW24 of FIG. 3 is not pressed. The connection
progress sound is generated from the flat speakers 21 directly below all the infrared sensors 22.
[0027]
Next, an example of the call state will be described.
[0028]
When the start button unit 14 is pressed, a call is made, and the other party answers and enters a
call state.
In the call state, it is the same as an example of transmission except that the voice of the user is
delivered to the other party by the microphone unit 12 and the call sound is generated from the
09-05-2019

flat speaker 21 in the reception matrix configuration unit 11, and detailed The description is
omitted.
[0029]
In this simple phone 10, a light reception time range from the irradiation of infrared light of the
infrared sensor 22 to the reflected light will be described. FIG. 5 shows a time range in which the
reflected light is detected after the push button SW24 is turned on and the infrared sensor emits
infrared light. The horizontal axis represents time (msec), and the vertical axis represents the ON
/ OFF state of the push button SW24.
[0030]
As described above, when the user presses the start button portion 14 and then the user's ear is
pressed against the push button SW24, and the push button SW24 is not pressed (OFF) but is
pressed (ON) (ON) ( 3 → FIG. 4), the infrared sensor 22 in the receiving matrix construction unit
11 starts infrared irradiation, and this point is A (0 msec) in FIG. Thereafter, a connection
progressing sound that is in the middle of connection is generated until the other party answers.
[0031]
If the user's ear is pressed against the push button SW24, the infrared light emitted from the
infrared sensor 22 is received within a predetermined time range. The time range for detecting
the reflected light is a section B of FIG. 5 and is between 2 and 9 msec after infrared irradiation.
Among the reflections, the point of the slowest reflection time is C (9 msec). Since the section B
receives light when the push button SW 24 is in the ON state, the section B is on the D direction
side larger than the middle threshold of the push button SW (shaded portion).
[0032]
Thus, the position of the ear canal of the user pressed against the reception matrix forming unit
11 is detected by the infrared sensor 22, and the connection progress sound or the call sound is
emitted only from the flat speaker 21 at the position of the ear canal. The effect of being able to
always confirm the connection progress sound or the call sound in the best position for the
person is produced.

[0033]
Among the reflected light detected in the B range after infrared irradiation, the flat speaker /
infrared sensor control board unit 25 always determines that the position of the infrared sensor
22 that took the longest time to be detected is the user's ear canal Then, the connection progress
sound and the call sound are generated only from the flat speaker 21 at that position.
[0034]
Further, in the simple phone 10, the relationship between the transmission and the end of the
speech will be described based on the combination of the time when the button SW24 is pressed
or separated within a predetermined time range.
FIG. 6 shows a time range for detecting the case where the push button SW24 changes from OFF
to ON.
[0035]
For example, at the time of making a call, the user inputs the telephone number of the other
party to be called by the dial input button unit 13, and then the user's ear is pressed against the
push button SW 24 in the reception matrix configuration unit 11.
Then, when it is confirmed within the F time range (0 to 3 sec) of FIG. 6 that the push button
SW24 is in the pressed state (ON) from the non-pressed state (OFF), the flat speaker / infrared
sensor control The substrate unit 25 starts the transmission operation.
[0036]
Furthermore, disconnecting a call by turning on / off the push button SW 24 will be described
below. FIG. 7 shows a time range in which the push button SW24 detects repetition of ON / OFF.
09-05-2019
10
[0037]
When the push button SW24 is pressed (ON) and not pressed (OFF) are repeated twice within the
G time range (0 to 6 sec) of FIG. 7, the flat speaker / infrared sensor control board unit 25 starts
the end call operation and disconnects the call.
[0038]
Thus, the user can perform transmission / disconnection simply by pressing the ear against the
reception matrix forming unit 11 without pressing the start button unit 14 or the end button unit
15, and the operation is simple.
Therefore, the switching operation at the time of taking notes of the contents of the call is greatly
simplified, and the convenience is improved for seniors and those who use the mobile phone for
the first time.
[0039]
As described above, in the simple phone 10, the infrared sensor 22 detects the position of the
user's ear canal, and generates the connection progress sound and the call sound only from the
flat speaker 21 at that position. However, when sound is generated from the flat speaker 21 at
pinpoint in the ear canal, it is also necessary to perform control corresponding to movement of
the ear in a short time. Therefore, if the flat speaker at the position of the ear canal and the flat
speaker around it are also pronounced, even a control system that is somewhat inferior in
correspondence can be sufficiently used.
[0040]
For example, if the detection position of the user's ear canal is at the center of the reception
matrix forming unit 11, (1) in FIG. 8; if it is upper right, (2) in FIG. 8; if it is upper left, (3) in FIG.
If there is (4), the connection progress sound and the call sound are generated from the hatched
portion of (5) in the lower right, (6) in the upper center, and (7) in the lower center.
[0041]
If it is determined that there is no reflection to radiation within a certain fixed time range, and if
the push button SW 24 in the reception matrix configuration unit 11 is in a state where it is
09-05-2019
11
pressed from the state where it is not pressed, all flat speakers 21 The connection progress
sound and the call sound are generated from (the hatched portion of (8) in FIG. 8).
