DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device that emits a key click sound from a receiver.

[0002]

2. Description of the Related Art There has been proposed a telephone device that emits a key click sound from a receiver to confirm that a key has been pressed (see Japanese Patent Application Laid-Open No. 62-272738).

[0003]

However, since the key click sound is set so that it sounds at an appropriate volume when operating while looking at the key, it is very close to the ear when the key is operated during a call, so that it is extremely difficult. Will be heard as loud.

[0004]

SUMMARY OF THE INVENTION In view of the foregoing, a telephone device according to the present invention is provided with a speaker disposed in a receiver and transmitting a key click sound, and a volume of the key click sound transmitted from the speaker. And control means for setting the key click sound to a volume lower than a predetermined level during a call and setting the key click sound to the volume set by the setting means when a call is not performed.

Embodiments of the present invention will be described with reference to the drawings. The telephone device of the present embodiment is a CDMA mobile phone that uses a plurality of carriers of the same frequency in the same cell. FIG. 1 is a block diagram showing a configuration of a main part of the embodiment. 2 is a front view of the apparatus, FIG. 3 is a left side view, and FIG. 4 is a rear view.

A communication unit (1) transmits a signal from a baseband unit (3) to be described later to a base station via an antenna (2), and transmits a signal from a base station via the antenna (2). Or receive.

[0007] (3) is a baseband unit, which is CDMA
It has a processing circuit (31) and an audio codec (32).
The CDMA processing circuit (31) performs code division multiple access, scrambling, error control, and timing detection. The audio codec (32) compresses (encodes) and decompresses (decodes) audio.
Or a conversion between analog and digital, and changes the reception volume and microphone sensitivity by an internal amplifier circuit (not shown).

A speaker (4) is provided in the receiver (40 in FIG. 2) and is used for talking to the ear and used for talking. The electric signal of the baseband section (3) amplified by the amplifier circuit (5). Is converted to audio. The speaker (4) is a Conn.
A warning sound (for example, “beep-beep” or speech synthesis words) in the ON state of ect Alert and a key click sound are generated. Reference numeral (6) denotes a microphone used for a telephone call, which is disposed in a transmitting section (60 in FIG. 2) and converts voice into an electric signal. (7) is an amplifying circuit, which amplifies the output of the microphone (6) and outputs it to the baseband unit (3).

(8) is the received sound (for example, weather forecast)
The speaker is arranged so that the direction of sound output is opposite to that of the ear speaker (4), as shown in FIG. The speaker (8) converts the electric signal of the baseband section (3) amplified by the amplifier circuit (9) into sound. Further, the speaker (8) generates a ring tone (for example, "le-le-le" or a melody) as a notification of the line connection.

A switching circuit (10) turns ON / OFF the connection between the three respective amplifier circuits (5), (7) and (9) and the baseband section (3) under the control of a control circuit (11) described later. O
FF. Note that these three amplifier circuits (5) and (7)
In (9), the gain is fixed, and the receiving volume, key click volume, and microphone sensitivity cannot be changed. The voice codec (32) of the baseband unit (3) changes the reception volume, key click volume, and microphone sensitivity under the control of the control circuit (11).

Reference numeral (11) denotes a control circuit composed of a microprocessor, and a ROM (1) storing an operation program.
Each part is controlled based on 2). (13) is a RAM for storing information necessary for the operation of the control circuit (11).
(14) is a liquid crystal display unit for displaying telephone numbers and characters for various settings. (15) is a vibrator,
Vibration is generated at the time of incoming call based on the control of the control circuit (11).

An input unit (16) is a numeric keypad (161) for inputting a telephone number and the like, a call key (162) for starting a call and starting a call, and an end for operating a call end and the like. A talk key (163), a VOL key (164) (△ key and ▽ key in FIG. 3) for controlling the receiving sound volume, a MON key (165) for producing a receiving sound from the speaker (8) on the back, It has an F1 key (166) and an F2 key (167) for operating functions corresponding to the characters displayed on the display unit (14). As shown in FIG. 3, a VOL key (164) and a MON key (165) are provided on the left side, and the user can easily operate these keys even during a call.

The control circuit (11) produces a key click sound from the speaker (4) when a key of the input section is pressed. There are four types of volume: 0: silent, 1: weak, 2: medium, 3: strong (see FIG. 5), and one of the four types is set by a predetermined operation of the F1 key (166) and the numeric keypad. You. Normally, pressing the key while looking at the numeric keypad (161),
That is, the sound volume is set to “medium”, which is an appropriate volume when the ear speaker (4) for producing the key click sound is separated from the ear by about 40 cm.

Next, the main operation of the present invention will be described. FIG. 6 is a flowchart showing the operation of the control circuit (11). The control circuit (11) is busy (Y in S1) and the key click sound is not set to 0 (silent) or 1 (low) (N in S2), that is, the key click sound is 2 ( If it is set to "medium" or 3 (strong), the key click sound from the speaker (4) is set to 1 (weak) and output (S4). The control of the volume of the key click sound is performed by the control circuit (11) controlling the audio codec (32) of the baseband unit (3).

The key click sound is 0 (silent) or 1
If it is set to (weak) (Y in S2), the sound is set to the set silent or 1 (weak) (S3). If no call is being made (N in S1), a key click sound is generated as set (S3).

For example, when the key click sound is set to 3 (high), during a call, the VOL disposed on the side
When (164) or MON (165) is pressed, the key click sound is made 1 (low). As a result, the user who has brought the receiving speaker close to his / her ear will hear the key click sound with a low volume.

The present invention can also be applied to a telephone device that outputs a key click sound with an earphone.

[0018]

As described above, according to the present invention, the key click sound during a call is set to a predetermined low volume, so that the user can avoid hearing a loud click sound during the call.
