FIELD OF THE INVENTION The present invention relates to telephones such as single telephones
and key telephones. Prior Art A prior art example is shown in FIG. As for the ringing tone of the
telephone, a ringing tone signal is generated in the telephone main body 21 and applied to the
speaker 26 or the sound generator 26 built in the main body to emit the ringing tone. That is, a
speaker for a ringing tone or a speaker is separately incorporated. 22 is a handset, 23 is a
handset, and 24 is a handset. Problems to be solved by the invention In recent years, the
telephone circuit has been computerized, and further, the shape 9 function as a telephone set is
also diversified, but one of the things that hinders the freedom of the shape is ringer for ringing
tone generation. There is a speaker. That is, as shown in FIG. 2, the ringer speaker 26 requires a
considerable space to be housed inside the main body, which hinders downsizing and thinning. A
ringer made of piezoelectric ceramic has recently been used to improve the above points, but in
terms of sound quality it is difficult to say that it is a metallic sound and is optimum as a ringing
sound. The present invention seeks to provide a telephone which can eliminate the disadvantages
of the prior art. Means for Solving the Problems The present invention is characterized in that a
sound hole and a sound path are provided in the main body, and the sound is emitted without
being blocked by the handset. Operation As mentioned above, the sound passes through the
sound path received inside the ringer body applied to the handset's transmitter (or receiver or
both) and emits sound from the sound release hole at the other end of the sound path So you can
design the shape of the body quite freely. EXAMPLE An example of the present invention is
shown in FIG. In the telephone set body 11, the handset 12 is mounted on a concave handset
stand, and the handset 12 incorporates a transmitter 14 and a receiver 13. Further, a sound hole
16 is provided in the main handset stand on which the transmitter 14 of the handset 12 faces, a
sound path 16 is formed, and the other end is a sound emission hole 17. In this embodiment,
although the transmitter is used as a ringer, the same effect can be obtained even when the
receiver is used as a ringer or both the transmitter and the receiver are used as a ringer.
According to the present invention, since the speaker for the ringer can be omitted, the thickness
can be considerably reduced in space, and the shape of the sound path can be considerably free
if the volume is the same. There is also a high degree of freedom in the phone design.
In addition, the sound quality and volume of the ringing tone can be kept at the same level as the
conventional one, and in terms of cost, only some parts forming the sound path are necessary,
Since shaping is possible, cost reduction of an amount close to the amount at which the ringer
speaker can be omitted is possible, and the effect is great.
