Problems solved by technology

However, in the structure in which two springs that apply force to different directions are set on the hammer, if the spring force of the spring that applies force to the hammer to the gong side is strong, when the hammer strikes the gong, the gong The hammer does not leave the gong, which hinders the vibration of the gong
On the contrary, if the spring force of the spring that pulls the hammer back from the gong is strong, the force to strike the gong becomes weak, and there is a problem that a good sound cannot be produced.
Therefore, it is necessary to appropriately set the force of these elastic forces, but if the springs that urge in opposite directions are directly attached to the hammer, there is a problem that it is difficult to set each spring to an appropriate elastic force.

no. 1 approach

[0102] A first embodiment of the present invention will be described with reference to FIGS. 1 to 5 .

[0103] [1. Overall structure]

[0104] FIG. 1 is a longitudinal sectional view showing a timepiece 1 according to a first embodiment of the present invention. The timepiece 1 has a movement 1A as a main body, an inner case 10 housing the movement 1A, a bell 20 as a bowl-shaped sound source provided outside the inner case 10 , and an outer case 30 covering the bell 20 . The timepiece 1 of the present embodiment is an electronically controlled mechanical timepiece that drives the hands by the driving force of the mainspring, and supplies electric power generated by the driving force of the mainspring to an electronic circuit to adjust the speed.

[0105] Although not shown, the movement 1A has: a mainspring; a drive train that drives the hour hand 1B, minute hand 1C, and second hand 1D with the driving force of the mainspring; a generator that generates electricity using the ...

no. 2 approach

[0199] Next, refer to Figure 6~ Figure 8 A second embodiment of the present invention will be described.

[0200] In this embodiment, a gong is used as a sound source instead of a bell, and the timepiece of this embodiment has a repeater mechanism. In addition, the timepiece of this embodiment is a transparent cover (see through back) specification in which glass is provided on the back cover side. Furthermore, in this embodiment, a striking force transmission member different from that of the first embodiment is used. Except for these points, the timepiece of this embodiment has substantially the same configuration as the timepiece 1 of the first embodiment.

[0201] FIG. 6 is a longitudinal sectional view of the timepiece 7 according to this embodiment, and FIG. 7 is a transverse sectional view of the timepiece 7 . In addition, in FIG. 7, the components other than the hammer main body 41 and the hammer release device 43 of the movement are not shown in figure.

[0202] ...

no. 3 approach

[0233] Next, refer to Figure 9~ Figure 11 A third embodiment of the present invention will be described.

[0234] In this embodiment, the assembly structure of the inner case and the outer case is different from the above-mentioned embodiments. In addition, in this embodiment, a striking force transmission member different from that of the above-described embodiments is used. Except for these points, the timepiece of this embodiment has substantially the same configuration as the timepiece 7 of the second embodiment.

[0235] FIG. 9 is a longitudinal sectional view of the timepiece 8 of the present embodiment. In this FIG. 9 , a cross section of a portion where the stem 1E is provided (the right half in FIG. 9 ) is shown. In addition, FIG. 10 is a cross-sectional view of the timepiece 8 . In this FIG. 10 , components other than the hammer main body 41 and the hammer release device 43 of the movement 7A are not shown.

[0236] The timepiece 8 has: a movement 7A; an inner ca...

Abstract

The present invention provides a timepiece and a portable device. In the timepiece that produces sound by vibrating when struck, the elastic force of each spring can be easily set, and superior sound can be produced. The timepiece (1) having a movement (1A) having a hammer (40) and a hammer drive device (40) that drives the hammer, a sound source (20) that produces sound by vibrating when struck by the hammer, and a striking force transmission member (50) that can move bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer (40) to the sound source (20).

Description

technical field [0001] The present invention relates to watches and portable devices having sound sources such as gongs and bowl-shaped sound sources. Background technique [0002] Conventionally, a chiming timepiece (sounding timepiece) including a C-shaped gong and a hammer striking the gong is known (for example, Non-Patent Document 1). Here, the gong is arranged along the outer periphery of the movement and fixed on the main plate. In addition, the hammer is rotatably provided on the inside portion of the gong on the main plate, and is driven at a predetermined timing by the driving force of the mainspring. In addition, a spring that pulls back the hammer that struck the gong is provided on the main board. [0003] Non-Patent Document 1: "Latest Wrist Timepiece Fleur Spectrum Book 2002" Kakukakusha Co., Ltd., March 1, 2002, page 117 [0004] In addition, in the above-mentioned existing chime timepiece, be the structure that directly strikes the gong by the hammer, the...
