Description

[Detailed Description of the Invention] The present invention relates to a timepiece with an electronic sounding device, which is equipped with a sounding section for generating melodies and the like.

An object of the present invention is to provide a timepiece with an electronic sounding device that is capable of generating melodies and the like by constructing the sounding section with an electronic circuit and having means for determining the length of each note.

Conventional clocks with time and alarm functions typically have a built-in mechanical music box or a metal rod that is struck with a hammer. However, a mechanical sounding section increases the size and weight of the watch body, and production of multiple melodies is difficult due to cost and implementation considerations, and it is not easy to change the melodies. Therefore, there is a need for a timepiece with an electronic sounding device in which the sounding part is also electronic in parallel to the electronic timepiece part. In addition, there is a need for a clock with an electronic sounding device that can generate not only a monotonous buzzer sound and a time stamp but also a varied buzzer sound and melody.

The present invention eliminates the above-mentioned drawbacks and satisfies the above-mentioned demands regarding a clock with an electronic sounding device, which is composed of an electronic circuit that starts and stops sound generation in response to time signals, alarms, and signals generated by external operations. This is a clock with an electronic sound device. FIG. 1 shows an embodiment of a timepiece with an electronic sounding device according to the present invention. Oscillator 1
01, it is desirable to use a crystal oscillation circuit for accuracy as a timepiece, but of course other CR oscillation circuits can also be used effectively. Generally the oscillation frequency is 32.768KHz or 4.192M
A Hz crystal oscillator circuit is often used. Oscillator 1
The signal from 01 is frequency-divided by the frequency dividing section 102 and sent to the time display section 103. The time display section 103 is composed of a time signal counting circuit, a decoder, a display drive circuit, a display body, etc., or a motor drive circuit, a motor, a dial, etc. Frequency control section 107 divides the signal from frequency division section 102 at a frequency division ratio determined by the first data output from storage section 109, and outputs the resulting signal to a desired frequency to number address counter 108. The address counter 108 scans the addresses in the storage section 109, and based on the scan, the storage section 109 outputs the first data and second data to the electronic sound composition section 104. In the initial state, the storage unit 10
9 is in a state where the content of the address in the initial state is outputted to the frequency control circuit 107 and the electronic sound configuration section 104, and the address counter 108 receives a time signal, a signal indicating an alarm time, or a signal generated by an external operation. Then, the storage unit 109 outputs the contents of the addresses that are sequentially scanned from the initial address. The first data input to the frequency control section 107 determines the frequency of the input to the address counter 108 by controlling the frequency division ratio for dividing the signal from the frequency division section 102 as described above. Therefore, the first data is stored in the address counter 108 in the storage unit 1.
The speed at which data is read from 09 is controlled, and when the output time for a certain data has passed, the next address is specified, and the addresses are scanned in order at a speed determined by the data in 1, resulting in a change in the length of the sound. The situation is decided. The second data is data for determining the electronic sound in the electronic sound composition section 104. For example, when an AND circuit is used as the electronic sound composition section 104, the second data is data for determining the electronic sound in the electronic sound composition section 104. It will be decided whether or not to do so. Therefore, in this case, the second data determines the presence or absence of intermittent sounds, and the first data determines the length of each sound. The output of the electronic sound configuration section 104 is amplified by the amplification section 105 and emitted by the sound generation section 106.

FIG. 2 shows another embodiment of a timepiece with an electronic sound generating device according to the present invention, in which the electronic sound forming section 104 of FIG. 1 is configured to be able to generate a melody. The same parts as in FIG. 1 are given the same numbers. 110 is a scale frequency control unit; 1
Reference numeral 11 denotes a waveform forming section 112, which is an envelope applying section, and constitutes the electronic sound composing section in FIG. The scale frequency control section 110 sets the signal from the frequency dividing section 102 to a desired frequency based on the second data from the storage section 109 to generate a predetermined musical scale. In this case, the second data is data specifying the scale of the melody. The waveform forming section 111 forms a waveform into a sine wave, a triangular wave, or the like to form the tone of the electronic sound. The signal having the required frequency, length of each note, and waveform is given an envelope by the envelope giving section 112 and sent to the amplifying section 105 and the sounding section 106 .
The first data from the storage section 109 is applied to the frequency control section 107 to control the frequency division ratio of the frequency control section 109, thereby changing the address scan speed of the address counter 108. for example,
If it is an eighth note, the frequency division ratio of the frequency control section 107 is set to 1/
If the first data of the storage unit 109 is outputted as the first data in the storage unit 109, such as dividing the frequency by 2 or 1/4 in the case of a quarter note, the address speed will be 1/4 of that of an eighth note in the case of a quarter note. 2, and the same data is output from the storage unit 109 for twice the time of an eighth note. The storage unit 109 stores data on the scale and length of each note making up a melody in address order according to the melody, and as the address counter 108 advances, the notes of a predetermined scale are sequentially played with a predetermined length. occurs and becomes a melody. The above is a basic configuration diagram showing an embodiment of a watch with an electronic sound device according to the present invention, but the watch with an electronic sound device further includes a circuit section for adding an echo effect, a vibrato, and a tremolo. It may be provided. Further, in the configuration diagram showing the embodiment of the present invention, an electronic sound configuration section 104, a frequency control section 1
07. Input to the scale frequency control unit 110 is performed from the frequency dividing unit 102, but for reasons of scale and time signature, separate oscillation units may be provided for each, or only one of them may be provided with a separate oscillation unit, or Each or either of them can also obtain an input signal from the oscillation section 101. Furthermore, by providing a plurality of the configurations shown in the above embodiments, a timepiece with an electronic sounding device capable of accompaniment can be obtained.

The clock with an electronic sound generating device according to the present invention is equipped with tone length determining means by controlling the output time of data sequentially read out from the storage section, and therefore, the length of each tone of the intermittent electronic tone, The length of notes and rests, which are essential for melody generation, and the length of rests can be freely changed depending on the contents of the memory section, allowing users to enjoy the generation of varying buzzer sounds and melodies. The clock with an electronic sounding device according to the present invention has a tone length determining means constructed of a digital circuit, and in parallel with the integration of the clock section, the sounding section is also integrated into an integrated circuit. Can be made into chips,
This greatly contributes to making watch bodies smaller and lighter. In addition, by using electronics and integrated circuits, costs are lowered, higher reliability is achieved, and modern electronic sounds are generated. Also, songs can be easily selected and changed by changing the reading position of the memory section or replacing the memory section. There are advantages that can be achieved.

In terms of integrated circuits, C-MOSIC, which has low power consumption, would be suitable for use as a watch. The clock with an electronic sound generating device according to the present invention is an all-electronic clock equipped with a storage section and a tone length determining means for controlling the output time of data from the storage section, and will be used as a clock with a sounding section in the future. It can be used effectively.
