Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system clock that can be used by freely combining a speaker unit and a portable clock unit with respect to a watch body.

[Conventional technology]

Conventionally, for example, in Japanese Utility Model Application Publication No. 58-65595, an external speaker can be connected to the watch body,
A clock has been proposed that is capable of outputting loud audio through an external speaker. Also, Utsukai Showa 55-
Publication No. 20494 proposes a clock system consisting of a reference clock that indicates Greenwich Universal Time and a group of additional clocks that operate in response to signals from the reference clock and indicate the time of a given year. These were designed to be sequentially mechanically and electrically connected to a reference clock.

[Problem to be solved]

The first conventional device simply connects the watch body and an external speaker in a detachable manner, making it impossible to enjoy a variety of combinations.
In the conventional world clock system, the number of additional clocks could be increased as needed, but the clocks that appeared to be the same were simply connected horizontally.

Therefore, an object of the present invention is to provide a system clock that can be used as a table clock by freely combining a portable clock unit and a speaker unit, which are originally used for portable use.

[Means to solve the problem]

In order to achieve the above object, the system clock according to the present invention includes a table clock body in which a digital clock circuit including an alarm circuit is built-in, and a table clock body that is provided with an output from the alarm circuit. An analog portable clock unit has a plurality of connectors connected in parallel to each other, an alarm mechanism and a sounding device to which a sounding signal is supplied via the alarm mechanism, and an analog portable clock unit that can be freely inserted and removed from the connector. a connection terminal integrally formed with the portable clock unit so as to be connectable, and to which a sound signal from the portable clock unit is supplied;
It has an integral connecting terminal that can be inserted into and removed from the connector, and is formed to have the same external shape as the portable watch unit, so that the output from the alarm circuit of the watch body and the sound signal from the portable watch unit can be connected to each other. The present invention is characterized in that it is constituted by a speaker unit that can be operated in either case.

〔Example〕

Hereinafter, details of the present invention will be explained with reference to embodiments shown in the accompanying drawings.

As shown in FIG. 1, a case 2 of the watch body 1 has a built-in digital clock circuit (not shown) having an alarm circuit, and a time display section 3 operated by this clock circuit. It is installed in the center of the front of the case 2, and the top of the case 2 has two speaker units 4 and an analog mobile clock unit 1.
1 is placed.

As shown in FIG. 2, connectors 6 and 8 for the speaker unit 4 and the portable watch unit 11 are provided on the upper surface of the case 2 of the watch body 1. The connectors 6 and 8 are common and connected in parallel by a pair of connection wires 7 shown in FIG. The circuit is connected. Therefore, all the connectors 6 and 8 are supplied with an alarm signal from the clock circuit. In addition, in FIG. 4, 10 is an external terminal connected to the connection line 7. Further, as shown in FIG. 2, a volume 3b for adjusting audio or alarm sound is provided on the side surface of the case 2.

As shown in FIGS. 5 and 7, the speaker unit 4 has guide grooves 4a formed on both sides, and can be mounted on the case 2 by being guided by guide columns 5 planted in the base 2. It is becoming.
A connection terminal 4b is provided at the lower end of the speaker unit 4, which can be connected to a connector 6 provided on the case 2 when it is mounted on the case 2 via the guide column 5.
is formed. Thereby, the speaker unit 4 is connected to the timepiece circuit of the timepiece body 1 via the connector 6.

The portable clock unit 11 is of an analog type that measures time independently of the clock circuit of the main body of the watch, and uses a small buzzer or the like activated by a built-in well-known Oram mechanism (not shown). It is equipped with a device (not shown) and can be used alone. The portable watch unit 11 is formed to have the same external shape as the speaker unit 4, and has a connection terminal at its lower end configured to supply the same sound signal as the sound signal supplied to the built-in sound device. 11b is formed protrudingly. This portable clock unit 11 also has a speaker unit 4.
Guide grooves 11a (see FIG. 5 or 6) are formed on both sides of the case 2, and these guide grooves are guided by the guide columns 5 so that the case 2 can be mounted on the case 2. Guide pillar 5 for mobile watch unit 11
When mounted on the case 2 via the connecting terminal 11b, the connecting terminal 11b is connected to the connector 8. Therefore, the sound signal from the portable watch unit 11 is also supplied to the remaining connectors 6 connected in parallel with the connector 8, and the sound signal is also supplied from the speaker unit 4 to which these connectors 6 are connected. will be done. Since the system clock of the present invention has the above-mentioned configuration, the portable clock unit 11 can be removed from the clock body 1 and used alone in a pocket or handbag when going out for a trip or the like.

On the other hand, since the portable watch unit 11 can be inserted into the watch body 1 when not being carried, there is no need to lose the portable watch unit 11 or have to search for it when going out. When the portable watch unit 11 is attached to the watch body 1, the speaker unit 4 generates an alarm sound both at the time set in the portable watch unit 11 and at the time set in the alarm circuit of the watch body 1 itself. Can be done. Therefore, it has a two-system alarm function. Furthermore, it is also possible to connect a radio or the like using the external terminal 10 and generate sound from the speaker unit 4.

In addition, in the above embodiment, the connector of the watch body is
In this example, one portable clock unit and two speaker units are used in combination, but it is also possible to use a combination of two portable clock units and one speaker unit. The number is not limited to three either.

〔effect〕

According to the system clock according to the present invention described in detail above, the portable clock unit, which is originally used for portable use, is inserted into the connector of the clock body and incorporated as a component of the table clock when not in use. This allows you to avoid losing the small portable clock unit.In addition, all the connectors on the watch body are connected in parallel, so you can easily connect the alarm function of the watch body to the mobile phone. You can use all the alarm functions included in the clock unit.
Just by inserting the portable clock unit into the connector of the watch body, it can easily function as a clock with a multi-alarm function. Furthermore, since the connector on the watch body and the connection terminals for the mobile clock unit and speaker unit are all configured in common, users can freely attach the speaker unit and mobile clock unit to the watch body according to their preference. can be changed to
