Description

[Detailed description of the invention] The invention relates to a wristwatch configured to adjust the time by collecting time signal sounds from a radio receiver, etc.
In particular, it attempts to protect the microphone by providing a shutter on the sound hole of the microphone that picks up the time signal sound.

A conventional wristwatch was constructed as shown in FIG. That is, a microphone 3 for collecting time signal sounds from a radio receiver or the like is housed in a watch body 2 equipped with a digital display section 1 in order to adjust the time, and a sound hole 4 is provided in the housing section of the microphone 3. There is. The watch body 2 includes a watch band 5.
are combined.

In this configuration, the main body 2 of the watch is connected to the microphone 3 and the correction circuit 6 as shown in FIG.
The display circuit 10 of the clock function, which is composed of an oscillator circuit 7, a frequency divider circuit 8, a counter 9, a display circuit 10, and a display element 11, is connected to a correction circuit 6, and is configured to correct delays and advances.

In the above configuration, the microphone 3 has a sound hole 4
Because it communicates directly with the outside air through the air, it has the drawbacks of being weak in pressure resistance and weak in water resistance.

The present invention eliminates the above-mentioned drawbacks of the prior art.

Embodiments of the present invention will be described below with reference to FIGS. 3 and 4.

Reference numeral 12 denotes a watch body, which has watch bands 13 on both ends, and a digital display section 14 on this watch body 12.
A microphone 15 is built in to pick up the time signal sound from a radio receiver or the like for adjusting the time. A sound hole 16 communicating with the outside is provided in the housing portion of the microphone 15, and a shutter 17 is incorporated in a part of the sound hole 16. This shutter 17 is provided with a lever 18, the bent portion 19 of which is in contact with a time adjustment push button 20 provided on the watch body 12. The time adjustment push button 20 is provided with a tapered protrusion 21 that gradually protrudes laterally from the tip to the operation side at the portion that comes into contact with the bent portion 19, and the lever 18 is provided with a return spring 21.
2 is inserted.

In such a configuration, the return spring 22 is normally used.
As a result, the shutter 17 fits into the sound hole 16, and the microphone 15 is isolated from the outside air.

If you want to adjust the time in this state, press the time adjustment pushbutton 20 in the direction of arrow a, and the bent portion 19 of the lever 18 will move into the tapered protrusion 2.
1, the shutter 17 slides in the direction of arrow b against the return spring 22, and as a result of this sliding, the shutter 17 comes out of the sound hole 16. The microphone 15 is now in communication with the outside air, receives the time signal from a radio receiver, etc., and adjusts the time through the correction circuit 6 shown in FIG.

When the time adjustment is completed, the pressing force on the time adjustment push button 20 is released, and the return spring 22
As a result, the shutter 17 enters the sound hole 16, and the time adjustment push button 20 also returns in the direction opposite to the direction of the arrow a.

As the wristwatch of the present invention is constructed as described above, the time can be adjusted sufficiently, and since the microphone that picks up the time signal sound is normally isolated from the atmosphere, it has excellent pressure resistance and water resistance. The originally required waterproof function can be fully satisfied, and the structure can be made simple and highly reliable.
