Description

  The present invention relates to a telephone device, and more particularly to a telephone device suitable for use by a user of a hearing aid.

Hearing aids are roughly divided into the following three types a to c.
a. A type in which the body of the hearing aid is hooked on the back side of the ear and the earphone attached to the body is put into the ear (hook type)
b. A card-type main unit is placed in the chest pocket, and an earphone connected to the main unit with a cable is inserted into the ear (card type)
c. A type in which the body of the hearing aid is downsized and the hearing aid itself is placed in the ear (interpolation type)

When a user of such a hearing aid uses a telephone, there are the following problems.
In the case of the hook type, the microphone of the hearing aid (hereinafter referred to as a microphone) is located above the ear when the hearing aid is worn. For this reason, when the receiver is brought into close contact with the ear, leakage of the received sound is reduced and the received sound does not enter the microphone of the hearing aid. For this reason, it is inconvenient when using the telephone, such as intentionally leaking the telephone a little away from the ear and maximizing the volume of the telephone.
In the case of the card type, since the microphone of the hearing aid is provided in the main body in the breast pocket, the earphone of the hearing aid is removed (the hearing aid is not used), and the reception volume of the telephone is maximized.
In the case of the interpolation type, howling occurs when the ear is brought into close contact with the handset. Therefore, it is necessary to use the handset slightly away from the ear and increase the volume of the telephone.
Therefore, both types of hearing aids have a problem that the content of the call is heard by the surrounding people or the surrounding people are annoyed by noise by increasing the volume of the reception.

Therefore, in order to solve such a problem, as shown in FIG. 12, a hearing aid 53 having a microphone sound hole on the back surface and a sound groove tube 51 and an earplug 52 connected to the side surface is connected to a telephone handset 54. One that is fixed to the portion 55 with a rubber band 56 has been proposed (see Patent Document 1).

When the hearing aid 3 is operated in the microphone mode by operating a button (not shown), the switches 34 and 35 close the switch 34 and open the switch 35 and turn off the power of the short-range wireless communication unit 32. When operating in the telephone mode, the switch 34 is opened and the switch 35 is closed, and the short-range wireless communication unit 32 is turned on.

The operation of the telephone device having the above configuration will be described.
FIG. 2 is a flowchart of the process of the control unit 5 when an incoming call is received. An incoming call from the telephone line 4 is detected by an incoming call detection unit (not shown) through the external line interface unit 6, and the incoming call detection is notified to the control unit 5, whereby the processing shown in FIG.
When notified of incoming call detection, the control unit 5 closes the switch 28 and turns on the power of the short-range wireless communication unit 23 (step S1), and then determines whether the short-range wireless communication unit 23 has established a link. Determine (step S2).

  Here, if the user who is using the hearing aid 3 in the telephone mode at the time of an incoming call is near the handset 2, a predetermined procedure is performed between the short-range wireless communication unit 23 of the handset 2 and the short-range wireless communication unit 32 of the hearing aid 3. Is established (YES in step S2), otherwise the link is not established. When the link is established within a certain time, the short range wireless communication mode is set (step S4), and when the link is not established, the telephone mode is set (step S3). The mode setting information is stored in the storage unit 9.

  Next, based on the open / closed state of the hook switch 8, it is determined whether or not the handset 2 is picked up and off-hooked (step S5). If it is off-hook, it is determined whether or not the short-range wireless communication mode is set (step S6). If the short-range wireless communication mode is set (YES in step S6), the transmission path is set to the microphone. In addition to connecting to the unit 21, the reception path is connected to the short-range wireless communication unit 23 (step S8). That is, by closing the switch 25 and the switch 27, the call control unit 7, the microphone unit 21, and the short-range wireless communication unit 23 are connected by the audio signal transmission path. On the other hand, when the short-range wireless communication mode is not set (set to the telephone mode) (NO in step S6), the transmission path is connected to the microphone unit 21 and the reception path is connected to the speaker unit 22. To do. That is, by closing the switches 25 and 26, the call control unit 7 and the microphone 21 and the speaker unit 22 are connected by the audio signal transmission path (step S9). In either mode, the call state is established.

  Therefore, when there is an incoming call to the telephone device and there is a user who is using the hearing aid 3 in the telephone mode near the handset 2 and the user picks up the handset 2, the received voice signal from the caller is the call The signal is sent from the control unit 3 through the switch 27 to the short-range wireless communication unit 23, and transmitted from here to the short-range wireless communication unit 32 of the hearing aid 3. In the hearing aid 3, the short-range wireless communication unit 32 receives the received voice signal and outputs the received voice signal to the earphone 33 through the switch 35. The earphone 33 converts the received voice signal into the received voice. A user who uses the hearing aid 3 can listen to the received voice output from the earphone 33. At this time, since the switch 26 is open, the received voice is not output from the speaker 22. For this reason, the received voice that can be heard by the user of the hearing aid 3 is not the two places of the speaker and the earphone as in the prior art, but only the one that is output from the earphone 33, so that it can be easily heard without a sense of incongruity. The voice uttered by the user of the hearing aid 3 is converted into a voice signal by the microphone unit 21 and transmitted to the telephone line 4 through the switch 25, the call control unit 7, and the external line interface unit 6.

  Also, when a person who is not a user of the hearing aid 3 picks up the handset 2 when an incoming call arrives at the telephone device, the received voice signal from the caller is sent from the call control unit 3 through the switch 26 to the speaker unit 22 only. Since it is supplied, it is output only from the speaker unit 22.

  If no off-hook is detected in step S5, it is determined whether or not there is no incoming call (step S7). If there is no incoming call, the switch 28 is opened and the short-range wireless communication unit 23 is turned off. (Step S10), the end of call processing is performed.

  Note that FIG. 2 is configured to turn on the power of the short-range wireless communication unit 23 when an incoming call is detected, but when the user presses the outside line button of the key input unit 11 for outgoing calls, the near-field wireless communication unit 23 is similarly turned on. You may comprise so that the power supply of the distance wireless communication part 23 may be turned ON. In the above description, the switches 34 and 35 of the hearing aid 3 are opened and closed based on the operation mode set by the user. However, the link between the short-range wireless communication unit 32 and the short-range wireless communication unit 23 is used. The switch 34 may be opened and the switch 35 may be closed when the establishment is detected.
