Description

Phone with volume display

The present invention relates to a telephone terminal using the bone-induced hearing of the hearing impaired and the airway hearing of a normal normal hearing person. In particular, a volume display function is provided to visually display the received volume so that the hearing impaired can experience the received volume. It is about equipped telephone.

Telephone terminals, which are widely used throughout the company and our living spaces, including ordinary homes, are intended for normal people who make calls using prayer hearing, which is difficult for the hearing impaired to use.

On the other hand, according to Korean Patent Application No. 93-29598, filed December 24, 1993, in the case of hearing impaired people can be heard by converting the audio signal into vibration to listen to bone by hearing, normal normal Hearings have been introduced to the bone conduction phone using the bone conduction vibrator, which allows the user to talk using airway hearing.

In addition, the bone conduction phone is attached to the side of the phone to adjust the volume level in an analog manner, the hearing impaired person can make a call at a volume level corresponding to the degree of hearing impairment.

However, the hearing impaired person cannot recognize how much the current volume setting state is by only adjusting the volume level. Therefore, when the other party's caller talks at a lower volume than the general speaker's volume level, the hearing impaired person continues to the volume level. To increase the bar, there is inconvenience in operating the volume control device attached to the side of the phone.

In addition, in the above case, when the deaf person sets the volume high and switches the phone off, the deaf person is surprised because a sudden high volume level vibration is transmitted in the case of a subsequent call again. Problems may arise.

In addition, when a call is set again at a low volume level before the call, the hearing impaired person may determine that the phone is malfunctioning or may need to adjust the volume level again.

Accordingly, the present invention has been made in view of the above circumstances, and relates to a telephone having a call function using bone conduction hearing of the hearing impaired, and provides a telephone capable of visually discriminating a reception volume setting state through a display unit. Has its purpose.

2 is a detailed configuration diagram of the volume display function, in which the same reference numerals are assigned to parts performing the same functions as those shown in FIG. 1 and detailed description thereof will be omitted.

In FIG. 2, reference numeral 14a denotes a call volume composed of a switch SW1 operated in an ON state when the user presses the volume up key, and a switch SW2 operated in an ON state when the user presses the volume down key. It is an adjusting part.

Reference numeral 11A denotes a display driver for driving the light emitting display, and is composed of four resistors R1 to R4 and three comparators A1 to A3.

Here, in the three comparators A1 to A3, the output signal of the volume control section 8 is applied to each inverting terminal (-) input. Then, a plurality of resistors R1 to R4 are connected in series between the predetermined power supply voltage Vcc and ground, so that the non-inverting terminal (+) of the comparators A1 to A3 is connected.

In the above configuration, the light emitting diodes D1 to D3 corresponding to the strong, medium, and weak light are turned on according to the call volume output level. All the light emitting diodes D1 to D3 are turned on, and when the call volume is 'medium', the light emitting diodes D2 and D3 corresponding to the medium / weak light are turned on. Only the light emitting diode D3 corresponding to 'about' is turned on.

Meanwhile, the signal applied from the control unit 13 to the volume control unit 8 outputs a signal to the display unit 11 and the volume amplification unit 9, and the volume amplification unit 9 amplifies the input signal. It outputs to the bone mineralization part 5b of the handset 5.

In addition, the transmitter 5a of the handset 5 is combined with the network circuit 7 to convert a signal transmitted by the user into an electrical signal to be transmitted to the trunk line.

Next, the operation of the telephone having the above configuration will be described with reference to the operation flowchart shown in FIG.

During a call or in a normal standby state, when the volume control function key provided on the keypad 14 is selected and input by the user (ST1), the control unit 13 controls the volume control function key selected by the user. If it is determined whether the volume-lowering key is recognized, when the volume-up key is confirmed (ST2), the volume control unit 8 is controlled to set the volume level up one level (ST3).

On the other hand, in step ST2, when the input volume control function key is confirmed as the volume down key, the control unit 13 controls the volume control unit 8 to set the volume level one step down (ST4).

Subsequently, the controller 13 drives and controls the display unit 11 to display the volume setting state adjusted by the user through the light emitting display unit 11a. In this case, the display form is configured as the bone oscillator. When converted into the output volume of the receiver 5b, the display unit displays the values corresponding to the output strengths of the same level. (ST5)

Thereafter, the controller 13 checks whether there is an input of the volume setting completion key (ST6), and when there is an input of the volume setting completion key, sets the volume level to an adjustment value set by the user, and the light emitting display unit 11a. Control to display the sound set value as a designated value.

In step ST6, if there is no input of the volume level adjustment key for a predetermined time or more (ST7), the initial state is returned.

That is, according to the above embodiment, it is possible to realize a telephone which enables the volume control by the user and makes it possible to visually check the setting state of the volume which is variable by the user.

On the other hand, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.

For example, the position of the volume level adjusting key 14a of FIG. 4 is not necessarily limited to the upper surface of the telephone, and can be provided on the side of the telephone body as in a conventional telephone, and the volume level adjusting key 14a may be implemented using a control lever or the like that is not a button type.

In addition, in the above embodiment, the display step of the volume level display section 11a is divided into three stages of strong, medium, and weak, but correspondingly, three or more comparators and three or more diodes are provided. You can also set variously.

As described above, according to the present invention, the user can adjust the volume according to the degree of hearing impairment, and the volume setting state can be displayed through the light emitting display unit.
