Description

Adapter device for telephone

The present invention provides a voice reproducing apparatus and a telephone freely mounted on the ear for converting a received signal into a voice, and an adapter for connecting and reproducing a voice signal output apparatus and the voice reproducing apparatus. To an adapter device.

Conventional telephones are known as mounting telephones placed on a desk or the like, portable telephones that can be carried freely.

The installed type telephone has a telephone body which is installed by connecting to a telephone line installed at a predetermined position, and a handset composed of a handset for making a voice call and a handset receiving a voice call, thereby providing an electrical signal between the telephone body and the handset. Or a telephone in which transmission and reception of a call signal and a call signal in a form of radio wave or the like are performed.

The installation-type telephone is a method of notifying an incoming call, a method of informing the incoming call by emitting a buzzer or a ringing tone from the main body of a telephone or a telephone while simultaneously receiving the incoming call, or by receiving a flashing light from a flashing lamp installed in the telephone body at the same time. Three methods have been adopted, such as the notification method, and a combination of the two methods.

On the other hand, the portable telephone is a type of telephone capable of carrying and carrying a communication signal and a transmitted signal in the form of radio waves, and at the same time as the radio waves reach.

In such a portable telephone, as a method of notifying an incoming call, in addition to the three methods described above with respect to the installed telephone, a vibrator set to vibrate at the same time as the incoming call is installed in at least a part of the portable telephone main body. By carrying the portable telephone so as to come in contact with a part of the mobile phone, a method of informing the incoming call by transmitting the vibration of the vibrating unit to the body at the time of incoming call has been adopted.

Therefore, when a user receives an incoming call while listening to a radio program or music through a radio or headphone stereo as an audio signal output device by attaching an earphone or a headphone as a voice reproducing apparatus to the ear, Listening directly to the ear, or by noticing the vibration of the light or vibrating part blinking on the phone to know the incoming call, and turned off the radio or headphone stereo by hand, the earphone and headphones were removed from the ear to answer the call.

However, the conventional telephone has three problems listed below.

First, it is difficult for the user to notice the incoming call.

The installed telephone has a headphone or the like attached to the ear, and when the headphone or the like is used to listen to music, the external ear canal is blocked from the outside. When the volume of the music or the like that is being listened to is high volume without being heard, the incoming voice becomes more difficult to hear.

Since portable telephones often receive incoming noises, such as in trains or construction sites, when a user listens to music through headphones or stereo with headphones attached to the ears under such circumstances, In addition, the headphone or the like not only blocks the incoming voice, but also a large volume of voice from the outside world eliminates the incoming voice, so that the user may not be able to hear the incoming voice from the telephone at the time of incoming call.

In addition, a method of informing the incoming call by blinking light and transmitting the vibration by vibrating the vibrating part to the body is known in the former as to the installed type phone, and in the latter, the vibrating part contacts part of the body. As long as you are wearing headphones, you can use the headphones stereo to listen to the incoming call regardless of the volume of music and external voices. Since many users receive the call under this situation, the user may not notice the blinking of the light or the vibration of the vibrating unit.

Second, it is cumbersome to notice the incoming call and answer the call.

When listening to a radio program by a radio or the like with earphones or the like mounted on the ear of the installed telephone and the portable telephone, when the user notices the incoming call by any one of the four methods described above, the user may receive the call before the radio or the like. After the manual operation is stopped, the earphones, etc. need to be removed from the ear, so not only can you quickly receive a call after noticing an incoming call, but also hastened to pick up the call quickly and accidentally broke a device such as a radio or telephone. There is a fear.

And thirdly, the portable telephone also transmits unnecessary voices other than the call voice to the other party, depending on the situation when the portable telephone is received.

In the above-mentioned portable telephones, there are many situations in which a call is received, such as receiving an incoming call, in a car, a train, or a construction site. Therefore, when a call is made in such a situation, the caller catches the voice of the call and voice from outside. Because the voice is converted into a signal, the voice made by the user may not be heard well by the other party of the telephone.

The present invention is to solve the first problem described above, when the phone is received while listening to music, such as a headphone stereo, such as wearing a headphone or the like, the headphone stereo, etc. so as to notify the incoming call to the headphone, etc. And an adapter device for a telephone for a telephone which mutually transmits and receives a signal for voice communication between the telephone and the headphones.

The present invention is to solve the above-mentioned second problem, the phone and the radio to quickly receive a call in the state in which the earphone is attached to the ear, without having to remove the earphone from the ear after stopping the radio, such as by manual operation It is a second object of the present invention to provide an adapter device for a telephone that transmits and receives a signal for voice communication between an earphone and the like and a sound collecting device that collects voice calls.

The present invention solves the above-mentioned third problem, and even in a train or a construction site, the sound collecting device collects the voiced sound by bone conduction so as to collect only the voiced sound. It is a third object of the present invention to provide an adapter device for a telephone having a microphone, interposed between a telephone, a headphone stereo, a headphone, and the bone conduction microphone.
