Abstract

PURPOSE:To release the pain caused by a talking for a long time by mounting a transmitter and a receiver to a handset enclosure, using an attenuation means and manually attenuating the received sound volume. CONSTITUTION:When a user makes talking, a transmission voice is inputted to a transmitter 21, enters from a transmission line 25 to a telephone set 1 and the voice signal is sent to an opposite party. Simultaneously, a side tone is detoured to a reception line 26. Moreover, the transmitter 21 and the receiver 22 are housed in a handset 27 and a button 28 is provided on a recessed side. When the button 28 is depressed, the contact of a switch 23 is opened and when detached, the contact of the switch 23 is closed. When the switch 23 is closed, the side tone of the receiver 22 is attenuated to a proper sound volume through the attenuator. Since the user operates the button 28 and makes the sound proper, the pain caused by the side tone is reduced even with a long time phone call.

Description

【発明の詳細な説明】ｒ産業上の利用分野〕本発明は電話機の送受話器に関する。[Detailed description of the invention] r Industrial application field] The present invention relates to a telephone handset.

[Conventional technology]

従来の送受話器は、送話器から入込む送話音量から電話
機内の通話回路の構成によって定まる音量で受話器に入
込む音（側音）量が定められてｂ）た。In conventional handsets, the amount of sound (sidetone) entering the handset is determined by the volume of the transmitted voice input from the handset and the configuration of the communication circuit within the telephone.

[Problem to be solved by the invention]

上述した従来の送受話器は、送話音量から電話機内の通
話回路の構成によって定まる音量で側音量が定められて
外側から側音量のみを調節できないようになっているの
で、近年、商品化されている電話機には、受話音量の増
幅機能付きのものがあり、難聴者にとっては便利になっ
ているが、難聴者通しの通話を例にとると、相手の声を
聞きとりやすくするために、受話音量を最大にして会話
するため、自分の声（側音〉も増幅器で増幅されて受話
器に回り込み、長時間の通話には苦痛が伴う場合がある
という欠点がある。The above-mentioned conventional handset has been commercialized in recent years because the side volume is determined from the transmitting volume by the volume determined by the configuration of the communication circuit inside the telephone, and it is not possible to adjust only the side volume from the outside. Some telephones come with a function to amplify the voice of the person on the other end, which is convenient for people with hearing loss. Because they talk at maximum volume, their own voice (sidetone) is also amplified by the amplifier and is heard into the receiver, which has the disadvantage that it can be painful to talk for long periods of time.

[Means to solve the problem]

本発明の送受話器は、送話器と受話器とを実装するハン
ドセット筐体に前記受話器への受話音量を手動で減衰で
きる減衰手段を内蔵している。The handset and receiver of the present invention has a handset housing in which a handset and a handset are mounted, and includes a built-in damping means that can manually attenuate the volume of the voice received by the handset.

〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

After connecting the switch 23, connect the receiving line 26 to the telephone body 1 via R1.
is connected and configured.

次に、第１の実施例の動作について説明する。Next, the operation of the first embodiment will be explained.

第１図の第１の実施例は受話音を完全に遮断できる場合
の実施例である。即ち、本第１の実施例の使用者が話を
すると、送話音声は送話器２１に入力され、送話線２２
から電話機本体１に入り、音声が相手側に送出される。The first embodiment shown in FIG. 1 is an embodiment in which the received voice can be completely blocked. That is, when the user of the first embodiment speaks, the transmitted voice is input to the transmitter 21 and transmitted through the transmitter line 22.
The voice enters the telephone main body 1 and is transmitted to the other party.

器２２から使用者の音声は受話されなくなる。At the same time, the sidetone goes around from the telephone body 1 to the receiving line 26, so when the switch 23 is pressed, the contact of the switch 23 opens (the state shown by the solid line), and the user's voice is transmitted from the telephone receiver 22 to the receiving line 26. It will no longer be done.

第２図において、本第２の実施例が第１の実施例と異な

This is an example in which the signal can be attenuated by .

本第２の実施例の使用者の送話音声の送出線路は第１の
実施例の場合と同じであり、説明を省略する。The transmission line for the voice transmitted by the user in the second embodiment is the same as that in the first embodiment, and a description thereof will be omitted.

る。When the switch 23 is pressed, the contact point of the switch 23 is opened (the state shown by the solid line), and the sidetone of the user's transmitted voice from the telephone body 1 to the receiver 26 is attenuated by the attenuator 24.
It will be sent to the telephone receiver 22 through the telephone. Therefore, in the receiver 22, the sidetone is attenuated by the attenuator 24 and can be heard.

きる効果がある。In FIG. 3, in both the first and second embodiments, the button 28 of the switch 23 is mounted on the concave side of the handset housing 27 so that the handset 2 (or 2a) can be operated with one hand. When button 28 is pressed, switch 2
3 opens, and when the button 28 is released, the switch 23 contacts close 9 [Effects of the Invention] As described above, the present invention is provided with a damping means that can manually attenuate the volume of the voice signal to the receiver. For example, when a hearing-impaired person amplifies the received sound and makes a call, by pressing the switch of the attenuation means when transmitting a call, the received sound can be completely blocked or attenuated to an appropriate volume through an attenuator. Since the sound can be eliminated or attenuated to an appropriate volume, it has the effect of avoiding the pain caused by side sounds.
