Abstract

PURPOSE:To obtain a timepiece of simplified structure which is superior in design without using any external operation part having a movable member by controlling a current flowing through a voice recognizing circuit by a piezoelectric element as an input member. CONSTITUTION:A microphone 3 inputs and converts a voice into an electric signal and a voice recognizing circuit 8 recognizes a signal outputted by the microphone 3. A signal converting circuit 6 converts the output signal of the piezoelectric element 4 as the input member to a proper form. When the piezoelectric element 4 as the input member is struck with a finger, the piezoelectric element 4 generates an electric signal. The signal converting circuit 6 converts the output signal of the piezoelectric element 4 to the form which enables a power circuit 7 to be controlled. When a signal is received from the signal converting circuit 6 the power circuit 7 recognizes the output signal of the microphone 3 and further outputs a signal corresponding to a voice to control a timer circuit 9, thereby correcting the time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a voice input electronic timepiece equipped with a piezoelectric element as an input member.

[Conventional technology]

Conventionally, a voice recognition circuit including a microphone for voice recognition and an amplifier for amplification consumes a large amount of current. Therefore, if an attempt was made to create a voice-input electronic watch the size of a wristwatch using the voice recognition circuit, if the voice recognition circuit was used as is, current would constantly flow through the voice recognition circuit, shortening the battery life. . Therefore, an external operating member having a movable part is provided as a power switch for the voice recognition circuit, and the power switch is operated only when necessary to cause current to flow through the voice recognition circuit, and when it is not necessary, the voice recognition circuit is activated. Methods have been used to reduce current consumption without passing current through the circuit.

[Problem that the invention seeks to solve]

However, providing an external operating member with a movable part not only complicates the structure and makes processing difficult but also disadvantageous in terms of design, and voice input is performed without the external operating member having a movable part. The advantage will be diminished. There were such problems. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a voice input electronic timepiece that does not use an external operating member having a movable part.

[Means for solving problems]

In order to achieve the above object, the present invention has the following configuration. In other words, in a voice input electronic watch that has a voice recognition circuit and performs various operations such as adjusting the time by voice,
A power supply circuit for supplying current to operate the voice recognition circuit, a piezoelectric element as an input member for controlling the power supply circuit, and a signal generated by the piezoelectric element as a signal for controlling the power supply circuit. The configuration includes a signal conversion circuit for conversion.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

First Embodiment FIG. 1 is a front view showing the external appearance of a voice input electronic timepiece according to a first embodiment of the present invention, and FIG. 2 is a block diagram showing the circuit configuration. In FIG. 1, 1 is a voice input electronic watch, 2 is a case, 3 is a microphone for inputting voice, 4 is a piezoelectric element provided as an input member for converting pressure fluctuations into electrical signals,
5 is a display device for displaying the time. As shown in FIG. 1, the voice input electronic watch 1 includes a normal watch module (not shown), a micrometer, a piezoelectric element 4, and a display device 5 in a case 2.
It has a structure that incorporates To operate the voice input electronic watch 1, first apply pressure by tapping the piezoelectric element 4 with a finger, and then pronounce a predetermined command word into the microphone 3.

For example, if you say "correct", the voice input electronic clock 1 enters the correction state, and if you then say "12:38", the time can be corrected to 12:38.

Next, the circuit configuration of the voice input electronic timepiece 1 will be explained based on FIG. 2. In FIG. 2, a microphone is used to input audio and convert it into an electrical signal. 8 is a voice recognition circuit, which recognizes the signal output from the micro. Reference numeral 6 denotes a signal conversion circuit, which converts the signal output from the piezoelectric element 4, which is an input member, into an appropriate form. A power supply circuit 7 supplies power to the voice recognition circuit 8 and is controlled by a signal from the signal conversion circuit 6. A clock circuit 9 measures the current time and displays the time on the display device 5. Next, the operation of the circuit will be explained. Normally, no current flows through the speech recognition circuit 8, so speech is not recognized.

However, when the piezoelectric element 4, which is an input member, is tapped with a finger, the piezoelectric element 4 emits an electrical signal. The signal conversion circuit 6 converts the signal output from the piezoelectric element 4 into a form that can control the power supply circuit 7.

When the power supply circuit 7 receives the signal from the signal conversion circuit 6, it supplies power to the speech recognition circuit 8. Then, the voice recognition circuit 8 recognizes the signal output by the micro, and further outputs a signal corresponding to the voice to control the clock circuit 9, so that the clock can be corrected as described above. Note that at this time, current flows through the voice recognition circuit 8 and the current consumption of the entire circuit increases, but the power supply circuit 7 stops supplying current to the voice recognition circuit 8 if voice input is not performed for a certain period of time. That is, according to the above configuration, the piezoelectric element can be operated to operate the voice recognition circuit 8 only when the watch requires voice input operation, so the current consumption of the watch when normally carried is lower than that of a general electronic device. The current consumption can be made the same as that of a watch.

Second Embodiment FIG. 3 is a front view showing the external appearance of a voice input electronic timepiece according to a second embodiment of the present invention, and FIG. 4 is a block diagram showing the circuit configuration. The same numbers as in FIGS. 1 and 2 indicate the same components.

The difference in FIG. 3 from the first embodiment is that the piezoelectric element 4 is bonded to a back lid (not shown). The display device 5 also has a mode mark 5a indicating the current mode state.

Next, the circuit configuration of the second embodiment will be explained based on FIG. 4. The difference in FIG. 4 from the first embodiment is that an alarm circuit 10 is included. The alarm circuit 10 is controlled by the voice recognition circuit 8, stores the alarm time, and when the normal time and the alarm time match, sends an electrical signal to the piezoelectric element 4, causing the piezoelectric element 4 to vibrate and generate sound. That is, in this embodiment, the piezoelectric element 4 serves both as an input member and a sounding member. Other configurations and operations are completely the same as in the first embodiment.

In the second embodiment, piezoelectric elements are arranged, which has been widely used in alarm wristwatches. Therefore, there is an advantage in that it is possible to construct a voice input electronic timepiece using a piezoelectric element as an input member by simply attaching a microphone to an ordinary wristwatch with an alarm.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the current flowing through the voice recognition circuit can be controlled by the piezoelectric element as the input member, thereby reducing the power consumption when normally carried. or,
Since the piezoelectric element and the microphone are used as external operating members without using an external operating member having a movable member, the structure of the watch is extremely simplified and the design is convenient.
