Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone as a mobile communication terminal for mobile phones, and more particularly to a mobile phone with significantly improved usability.

[0002]

2. Description of the Related Art There is a strong demand for reduction in size and weight of mobile phones. With a retractable antenna, thin flat display, touch switch, and short stroke buttons, the surface of the mobile phone is a so-called smooth surface. In other words, there is little resistance when touching the surface, and it has become the mainstream of the market as a shape that fits in the hand. The transmitter (so-called microphone) and receiver (so-called speaker) of a mobile phone are becoming smaller, and are often arranged inconspicuously from the surface. In addition, in order to maintain the strength of the telephone while making it compact, a rounded shape, that is, a shape close to a rectangular parallelepiped or an ellipsoid having sharp corners is adopted in order to avoid extreme protrusions and irregularities.

Further, with the spread of pocket-sized portable telephones having a volume of 150 cc or less, the chances of operating the main body in a pocket are increasing. In addition, the functions other than the call such as answering machine recording and message message have been enhanced, and the switches and buttons to be operated have been increased in addition to the buttons necessary for the call.

FIG. 34 shows an example of a conventional mobile phone.
In the conventional mobile phone 101A shown in FIG. 34, it is necessary to secure the distance between the microphone 105 and the speaker 107 only for the distance between the mouth and the ear of the user of the mobile phone 101A. Since the length of the mobile phone 101A is limited, the size cannot be reduced. Therefore, in order to reduce the size of the mobile phone 101A when not in use and to ensure the length of the mobile phone 101A when in use, as shown in FIGS. 35 and 36, the microphone 105B,
There is provided a mobile phone 101B that is folded so that the 105C and the speakers 107B and 107C are inside.

On the other hand, as a device that also serves as a cassette player, there are radios and portable wireless materials. As a battery pack for these devices, conventional cylindrical single 1 type and single 2 type
There are batteries that use dry batteries, such as batteries, AA batteries, and gum-type batteries.

[0006]

First, considering the foldable structure, although the distance between the microphone 105B and the speaker 107B can be arbitrarily set according to the shape of the face of the user of the wireless communication terminal, the microphone 105B is not required. In addition, since the speaker 107B has a certain length, the opening angle differs depending on the user of the mobile phone.
Therefore, the positional relationship between the microphone 105B, the speaker 107B, and the ear is indefinite, and the sound collection efficiency of the sound from itself and the soundproof efficiency against external noise are significantly deteriorated. Further, in the foldable structure, the microphone 105B and the speaker 107B are opened during use, and the microphone 105B and the speaker 107B are not protected from the external environment such as temperature, moisture, dust and the like. Furthermore, microphone 105B
Also, the sound collection efficiency of the self-voice and the soundproof efficiency against external noise in the speaker 107B portion are low.

Therefore, a first object of the present invention is to improve the sound collection efficiency of own voice in the voice input device section and the sound insulation efficiency against external noise in the voice output apparatus section when using a portable telephone, It is to protect the voice input device unit and the voice output device unit and improve usability.

[0008] Further, with the miniaturization, the outer shape approaches a rectangular parallelepiped or a spheroid, and the symmetry of the shape is lost, so that it is difficult to distinguish the top and bottom / front and back of the telephone. Therefore, it can be judged by looking at the display in the daytime or where there is a light, but in a dark place it is difficult to distinguish the top / bottom / front / back of the telephone by only the sense of touch. In addition, some devices use light-emission displays so that they can be used even in dark places, but for the visually impaired, it is not possible to distinguish between upper and lower sides by the surface display of characters and light.

As described above, since it is difficult to distinguish the top / bottom / front / back sides of a telephone, it is difficult to bring the microphone (speaker) and speaker (receiver) of the telephone to the mouth and ears accurately, and voice is transmitted. The efficiency is significantly reduced and the original function of the telephone cannot be achieved.

In addition to the buttons necessary for making a call, making a call and receiving a call, there are many operation switches and buttons having new functions such as answering machine recording and message recording. Along with the miniaturization of mobile phones, the surface of a small phone body is now covered with many buttons. Therefore, in places where it is difficult to check the display, such as in dark places, pockets, or in bags,
There is a risk that the call may be disconnected by mistake by pressing a button, the call may not be received immediately even if a calling sound is emitted, or it may take time to make an emergency call.

Therefore, a second object of the present invention is to easily operate and make a call even in a dark place, in a pocket, in a bag or the like where it is difficult to confirm the display, the upper and lower sides, and the front and back sides, or even the visually impaired person. It is to provide a mobile phone capable of

Further, since the conventional battery pack has a small capacity, it becomes difficult to use a device that also serves as a cassette player for a long time. If the capacity is increased, the battery pack becomes larger.

Therefore, a third object of the present invention is to provide a large-capacity cassette tape type battery pack which can be replaced and set with a cassette tape in a cassette player and which enables long-term use of the equipment. It is in.

In order to achieve the above object, the first invention of the present application is, as shown in FIG. 1, voice input means 5 for converting a voice input into an electric signal, and input through a communication line. The voice output means 7 for generating a voice in response to the generated electric signal is provided between the voice input means 5 and the voice output means 7, and the distance between the voice input means 5 and the voice output means 7 is arbitrary. It is the gist to have the adjusting means 3 which can be adjusted.

The second invention of the present application is a mobile phone 1I having a microphone 5 and a speaker 7 as shown in FIG. 18, in which the distance between the center of gravity G and the microphone 5 in a cross section including the microphone 5 and the speaker 7 is The gist is that the distance between the center of gravity G and the speaker 7 is different.

Further, the third invention of the present application has a voice input function of converting an input voice into an electric signal and a voice output function of generating a voice according to the input electric signal as shown in FIG. A plurality of voice converting means 5 and 7, a comparing means 24 for comparing voice inputs of the plurality of voice converting means 5 and 7 in a communication state, and a result of the comparing means 24,
The gist of the present invention is to have switching means 21 and 25 for switching the functions of the voice converting means 5 and 7 which are large in voice input to the voice input function.

The fourth invention of the present application is a portable telephone 1L having a microphone 5 on one side and a speaker 7 on the other side as shown in FIG. Identification means A, B for identifying the direction in which the speaker 7 is present
It is a gist to have.

Further, in the fifth invention of the present application, as shown in FIG. 23, a call input means 9 for inputting a call operation,
A gist of the present invention is a mobile phone 1M having an incoming call input means 2 for performing an input relating to an incoming call operation, and having an outer shape capable of distinguishing between the outgoing call input means 9 and the incoming call input means 2.

[0019]

Since the mobile phone of the first invention of the present application has the adjusting means 3 provided between the voice input means 5 and the voice output means 7,
The distance between the voice input means 5 and the voice output means 7 can be arbitrarily adjusted, so that it can be degenerated and downsized when carrying, and can be extended according to the usability of the user during communication. it can.

The mobile phone of the second invention of the present application is the microphone 5
Since the distance between the center of gravity G and the microphone 5 and the distance between the center of gravity G and the speaker 7 in the cross section including the speaker 7 and the distance between the center of gravity G and the speaker 7 are different, a stable shape can be obtained.

The mobile phone according to the third aspect of the present invention has a plurality of voice converting means. The voice converting means has a voice input function of converting each input voice into an electric signal and a voice output function of generating a voice according to the input electric signal. Further, the comparing means 24 compares the voice inputs of the plurality of voice converting means in the communication state, and switches the function of the voice converting means 5, 7 having a large voice input to the voice input function. Therefore, the usability for the user is increased, and the degree of freedom in design at the time of production is increased.

The mobile phone of the fourth invention of the present application is the microphone 5
Even if the microphone 5 and the speaker 7 cannot be easily visually confirmed by the identifying means A and B for identifying the direction in which the microphone 5 is present and the direction in which the speaker 7 is present, the position of the microphone 5 and the speaker 7 is determined by the user. It can be used without making a mistake.

The mobile phone of the fifth aspect of the present invention has an outer shape capable of distinguishing the call input means 9 for inputting the call operation and the call input means 2 for inputting the call operation. Therefore, there is no fear that the call input means 9 or the like will be operated in a hurry when received.
