BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock body. More specifically, the present invention relates to a clock body in which hands are provided on a part of a front surface of a panel to which a photograph or the like is attached, which is also called a panel clock.

[0002]

2. Description of the Related Art Today, a clock body having a sounding function of generating an alarm sound by music or voice instead of a bell sound at an alarm time, or a clock body having a sounding function of sounding music at an hour is used. ing. The watch body with this sound generation function incorporates sound generation control means such as a melody IC and an amplification circuit in a movement provided on the back of the dial,
A small speaker is provided inside the back cover of the watch body that covers the movement, and when an alarm time comes, a melody or a sound is emitted from a speaker cone opened behind the watch body.

A power supply battery for driving a step motor for driving a hand and a power supply battery for driving sound generation control means, which are built in the movement and which are formed in the movement to form a battery storage section, are stored in the movement, There is a type in which a battery case separated from the movement is connected to the movement by a power cord to supply power to the movement.

[0004] In addition, when the sound emission control means is provided in the movement, not only is the sound emission control means such as a melody IC or an amplification circuit built in the movement main body, but the movement main body includes a wheel train for rotating a step motor and hands,
And built-in alarm contact and hour contact using cam,
In some cases, contact terminals provided on the back surface of the movement main body are connected to sound generation control means provided separately from the movement main body.

The tone generation control means forms an alarm signal or an hour signal at a predetermined time by connecting to a contact terminal of the movement body, and the amplification signal or the melody incorporated in the tone control means is generated by the alarm signal or the hour signal. The IC is operated to amplify an electric signal output from the melody IC storing the melody or voice signal data and to output the melody or voice from a speaker connected to the sound control unit.

In this case, there are a movement in which a power supply battery is provided in the movement main body, and a power supply battery which is provided in the sound emission control means connected to the movement main body by a power cord. Furthermore, today, in order to improve the appearance as an indoor decoration without having a sound-producing function, as shown in FIG. 9, a pointer 32 is provided on a part of the front surface of the panel 20 to which a photograph or the like is attached.

It has an amplifier circuit and the like. Hereinafter, the watch body 10 will be further described in detail. The panel 20 is disposed substantially parallel to the fixed plate 40 so as to form a predetermined space, and both of these plates are fixed to the frame body 50 at the periphery thereof. That is, the panel 20 and the fixing plate 40 are fixed to the frame 50 by forming parallel grooves 51 at predetermined intervals on the inner periphery of the frame 50 as shown in FIG. This can be easily performed by fitting the edges of the panel 20 and the fixing plate 40 together. Further, as shown in FIG. 5, between the panel 20 and the fixing plate 40,
A gap member 52 having a predetermined thickness is sandwiched, and further, the panel 20 and the fixing plate 40 sandwiching the gap member 52 are arranged inside a frame 50 having a cross section of an “L” shape, and The fixing plate 40 and the like may be fixed to the frame body 50 with screws 53.

A voice coil is provided between the panel 20 and the fixing plate 40 and substantially at the center of the panel 20.
60 is fixed. As shown in FIG. 4, the voice coil 60 is fixed by fixing the case 61 to the fixing plate 40 and bonding the front surface of the magnet 64 to the panel 20. The predetermined interval formed between the panel 20 and the fixed plate 40 is substantially the same as the thickness of the voice coil 60, and the voice coil 60 is sandwiched between the panel 20 and the fixed plate 40.

As shown in FIGS. 2 and 3, the fixing plate
At a predetermined position on the back of 40, the movement body 30
And the sound control means 70 are fixed. The pointer shaft 31 provided in the movement main body 30 penetrates the holes formed in the fixed plate 40 and the panel 20, and the tip thereof is located forward of the panel 20. And near the tip of this pointer shaft 31,
By attaching the hands 32 such as an hour hand and a minute hand, the hands 32 are provided on a part of the front surface of the panel 20.

As described above, the watch body 10 includes the voice coil 60 between the panel 20 and the fixing plate 40, and the voice coil 60 is fixed between the panel 20 and the fixing plate 40. ing. The voice coil 60 is provided with a sound control means.
By passing a signal current from 70, the magnet 64 is caused to reciprocate, and further, the panel 20 is vibrated to use the panel 20 as a diaphragm.

The panel 20 is formed of styrene foam or the like so that vibration is easily generated, and the fixed plate 40 is formed of a highly rigid metal plate or the like so that vibration is hardly generated. . Further, the Bose coil 62 is provided on the panel 20 so that the panel 20 can be evenly vibrated.
The movement main body 30 and the sound control means 70 are fixed to a fixed plate 40.

Therefore, it is possible to provide the watch body 10 which has good sound quality of the melody and voice to be emitted, makes it easy to hear the melody and voice, and does not hinder the operation of the movement body 30 due to the vibration at the time of sounding. Like that. As described above, the movement having the sound control means 70 is not limited to the case where the sound control means 70 is connected to the movement main body 30 by a signal line separately from the movement main body 30. Sometimes it is built inside. In such a case, a battery for driving the movement main body 30 can be shared as a power supply for operating the sound generation control means 70.

When the sound control means 70 is provided independently outside the movement main body 30, a battery storage section is provided in the sound control means 70, and a power supply for operating the sound control means 70 is provided for driving the movement. In some cases, the battery may be used in common, or in another battery different from the movement driving battery.
