Furthermore, a horn 6 is detachably attached to the volume switches 4, 4, as shown in FIG. This horn 6 has a box shape that covers the sound emitting part 3 and the volume switches 4, 4, and has a plurality of protrusions 6a inside. The sound emission paths 6b, 6b of the alarm sound are lengthened, the sound pressure is increased, and the sound is emitted to the outside. Further, the horn 6 has protrusions 6c, 6c formed on its lower surface that can be used to switch the volume switch 4,
By removably fitting it into the positioning recesses 4a, 4a of the watch case 1, it can be attached to the volume switches 4, 4, and the locking parts 6d, 6d formed on both sides thereof are attached to the side walls of the watch case 1. It is hooked onto the heads 5a, 5a of the push button switches 5, 5 provided in the holder, so that it does not come off upward. In this case, the sound emitting hole 3 is located in the center of the lower surface of the horn 6.
An elastic pressing portion 6e is formed so as to surround the outer periphery of a, and the horn 6 is pushed upward by the elastic pressing portion 6e. In addition, the locking portions 6d, 6

20 is pressed to perform switching (conducting contacts not shown), thereby adjusting the time, determining the alarm time, etc.

Next, a case will be described in which the electronic wristwatch configured as described above is used.

First, when using it by attaching it to the arm, the first
As shown in the figure, the horn 6 can be removed from the volume switches 4, 4 provided on the watch case 1.
That is, when removing the horn 6, the locking parts 6d, 6d of the horn 6 are separated from the respective heads 5a, 5a of the push button switches 5, 5 provided on the watch case 1, and the hooking is released. After that, all you need to do is lift the horn 6 upwards. Then, the protrusions 6c, 6c formed on the lower surface of the horn 6 separate from the positioning recesses 4a, 4a of the volume switches 4, 4, so that the horn 6 is removed. When the horn 6 is removed in this manner, the horn 6 does not get in the way even when the electronic wristwatch is attached to the wrist, making it highly portable.
Further, by pressing the volume switches 4, 4 as appropriate in this state, the volume of the alarm sound can be adjusted.
That is, when you press either volume switch 4,
The protrusion 4b formed on the lower surface of the switch plate 1
9 is pushed down to bring the switch plate 19 into contact with the electrode terminals 15 of the circuit board 12, thereby performing switching. This adjusts the volume of the alarm sound.

Furthermore, when using the electronic wristwatch as described above as an alarm clock, a horn 6 may be attached to the volume switches 4, 4 of the watch case 1, as shown in FIG. That is, when attaching the horn 6, after placing the horn 6 on the sound emitting part 3 and the volume switches 4, 4 provided on the watch case 1, as shown in FIG. Part 6

a, 4a, and the locking parts 6 on both sides.
d, 6d press buttons 5, 5 heads 5a, 5a
All you have to do is hook it to . Then, the elastic pressing part 6e at the center of the lower surface of the horn 6 comes into contact with the sound emitting part 3,
It is attached to the volume switches 4, 4 while being pushed up by the elastic pressing portion 6e. In this way, when the horn 6 is attached, the sound emitting part 3
The alarm sound generated from the speaker 18 passes through the sound emitting hole 3a and is emitted from the horn 6 to the outside, but since it is appropriately refracted by the projections 6a provided inside the horn 6, the sound emitting part As the lengths 6b and 6b become longer, the sound pressure increases, and as a result, when the sound is emitted to the outside, the sound becomes louder and the sound emission range becomes wider. Further, when adjusting the volume of the alarm sound with the horn 6 attached as described above, it is sufficient to simply press the horn 6. That is, when the horn 6 is pressed, the protrusion 6c formed on the lower surface of the horn 6,
6c presses down the volume switches 4, 4, so the volume switches 4, 4 operate in the same manner as in the case described above (when the horn 6 is removed) and perform switching. This adjusts the volume. In this case, since the notches 6f, 6f of the locking parts 6d, 6d are larger than the heads 5a, 5a of the push button switches 5, 5, the locking parts 6d, 6d move downward without being hindered by the heads 5a, 5a. Incidentally, when the horn 6 is released from the upper part by a finger, a hand, etc., the horn 6 is pushed upward by the elastic pressing part 6e.

However, according to the electronic watch with a horn as described above, the volume switches 4, 4 are provided on both sides of the sound emitting part 3 in the upper part of the watch case 1, and the horn 6 covering the sound emitting part 3 is provided on the volume switches 4, 4. By installing the horn 6, the volume switches 4, 4 can be operated via the horn 6 even after the horn 6 is installed, so not only is it easy to install the horn 6, but the volume switch can also be operated even after the horn 6 is installed. 4, 4 can be easily operated, and the volume of the alarm sound can be adjusted well.

[Effect of idea]

As explained above, according to the electronic watch with horn of this invention, a volume switch for adjusting the volume of the alarm sound is provided near the sound emitting part of the watch case, and the horn is attached to cover the volume switch and the sound emitting part. In addition, the volume switch can be operated via the horn even after the horn has been installed, so not only can the horn be easily installed, but the volume switch can also be easily operated even after the horn has been installed. There are advantages such as being able to easily and easily adjust the volume of the alarm sound.
