Description

  The present invention relates to a mobile phone that does not cause inconvenience to the surroundings even when a conversation is performed.

  In recent years, mobile phones have been used in various life situations. However, the conversations often cause trouble to third parties in the vicinity due to the conversations in use.

  Reflecting such a situation, for example, in a train, in a seated state, the use of a mobile phone is prohibited and is required to be used in a specific place (such as a deck).

  As described above, although the mobile phone is extremely convenient in life, a configuration with particular attention to the relationship with the third party in the vicinity as described above has not been proposed so far.

  Incidentally, Patent Document 1 describes a configuration in which a so-called howling phenomenon is prevented by blocking a sound signal from a microphone in another place by a mute means while the sound signal is being transmitted from a mobile phone. However, such a configuration is intended only for the convenience of a call on a mobile phone, and it is not disclosed or suggested to reduce the influence of the call on the surroundings.

  In Patent Document 2, a connection configuration between a mobile phone and a handset such as a microphone is disclosed. However, any configuration that eliminates inconvenience to the surroundings by using the mobile phone as described above is disclosed or suggested. I don't mean.

  Non-Patent Document 1 proposes a configuration in which a mute microphone is provided as a mute microphone so that generated sound is not dissipated around the microphone. However, there is no technical suggestion regarding the relevance to mobile phones.

Japanese Patent Application Laid-Open No. 11-4286. Japanese Patent Laid-Open No. 11-74951. Promotional advertisement screen display of mute microphone integrated with the homepage of CTA Co., Ltd. (1-5-3 Nogata, Nakano-ku, Tokyo)

  An object of the present invention is to provide a configuration of a mobile phone that does not cause trouble in the surroundings due to a telephone call.

  In order to solve the above problems, the basic configuration of the present invention is such that the tip portion is open and can be pressed around the mouth of a person, and the inner microphone is surrounded by a portion other than the tip portion. The mobile phone is provided with a silencer cover that is in a state, and is capable of transmitting voice input to the microphone by electrical connection with the microphone.

  In the case of the mobile phone based on the basic configuration, since the conversation in use is transmitted to the other party through the microphone in the mute cover, it may cause trouble to nearby third parties based on the use. It can be prevented or at least reduced, and as a result, it can be used while sitting in public transportation such as a train.

FIGS. 1A and 1B show typical embodiments of the present invention. A microphone 2 in a muffler cover 1 is connected to a transmission circuit 31 in a mobile phone 3, and a user can 2 (a), 2 (b) and FIGS. 3 (a), 3 (b), the silencer cover 1 is brought into contact with the periphery of the mouth portion 5 and then conversation with the other party is carried out using a mobile phone. , The sound produced by the conversation is filled in the silencer cover 1, but most of the sound is blocked without being transmitted to the outside, and leakage to the outside is prevented or reduced. You don't have to disturb others.
As shown in FIGS. 2 and 3, the silencer cover 1 surrounds the microphone 2 at a portion other than the tip, but a slight gap is generated at a portion where the cord 6 protrudes to the outside. Even if a portion that does not surround the microphone 2 is exceptionally generated due to the presence of the gap region, the present invention inevitably includes a case where the gap exists as long as such a case is also planned. This corresponds to an embodiment of the present invention.

  FIG. 1A shows an embodiment in which the transmission circuit 31 is connected exclusively to the microphone 2 in the silencer cover 1.

  However, the use of the mobile phone 3 does not always require the use with the silencer cover 1.

  In consideration of such a situation, as shown in FIGS. 1B and 4, a parallel circuit in which the microphone 2 in the silencer cover 1 and the microphone 2 in the transmission circuit 31 of the existing mobile phone 3 can be selected is formed. In the embodiment according to the above, the present invention can be applied to both the case where the microphone 2 in the silencer cover 1 is used and the case where the microphone 2 in the transmission circuit 31 is used.

When both microphones 2 coexist,
(1) As shown in FIG. 1B, the wiring cord 6 protruding from the microphone 2 in the silencer cover 1 through the silencer cover 1 is detachably connected. Form, or
(2) As shown in FIG. 4, an embodiment in which the microphone 2 in the silencer cover 1 and the microphone 2 in the transmission circuit 31 of the existing mobile phone 3 can be selected by a switch 34,
Any of these can be employed, and in either case, it is possible to appropriately select both the normal use state and the use state by the silencer cover 1.

  As with the mute microphone, the tip of the silencer cover 1 needs to be in a state where all or a corresponding portion around the mouth portion 5 can be pressed.

  Such a shape differs depending on the pressing part, but when the vicinity of the lips is pressed, the shape of the tip part is a substantially flat shape, but is a part that is somewhat distant from the periphery of the lips, that is, the figure. 2 (a), (b), and FIGS. 3 (a) and 3 (b), when pressing against the nose, cheeks and chin, the lower pressing portion is below the cross section ( A state of protruding so as to abut the jaw portion) is formed.

  In any case, the tip portion realizes a state in which almost or at least a rough gap does not occur with the skin and muscles around the mouth portion 5, and according to such a state, almost all or most of the pronunciation during a call is realized. It is possible to exert a function that does not leak to the outside.

  In particular, as shown in FIGS. 3 (a) and 3 (b), in the case of the embodiment in which the distal end portion of the silencer cover 1 is formed by an elastic body 11 that can be expanded and contracted, It becomes possible to make the said leakage prevention effect sufficient by closely_contact | adhering with this muscle.

  However, the elastic body 11 is preferably airtight, and a material with air permeability such as a sponge is not preferable in terms of preventing sound leakage.

  In the following, description will be made in accordance with examples.

  In the embodiment, as shown in FIG. 4, the receiving side circuit unit 32 can be connected to the earphone 4.

  That is, in the embodiment, it is possible to prevent or reduce the influence of the sound on the surroundings by connecting to the earphone 4 not only for the sound when transmitting during a call but also for the sound when receiving. It is said.

  The present invention can be used not only in the field of manufacturing, selling, and using a mobile phone, but also in the field of electronics such as a microphone.

It is a block diagram which shows the basic composition of the present invention, (a) shows the composition in which the transmitting circuit was connected only with the microphone in a silencer cover, and (b) shows the microphone in the existing cellular phone. And the microphone in the muffler cover coexist, and the tip of the cord connected to the latter microphone is detachable from the mobile phone. FIG. 3 shows a state in which a silencer cover that does not form an elastic body at the tip is pressed against the mouth, particularly under the nose, cheeks and chin, (a) is a side sectional view; b) is a top view. FIG. 3 shows a state in which the muffler cover forming an elastic body at the tip is pressed against the mouth, particularly under the nose, cheeks and chin, (a) is a side sectional view; b) is a top view. FIG. 10 is a block diagram showing a configuration of an embodiment using an earphone that is an embodiment in which a microphone and a microphone in a silencer cover in an existing mobile phone can be selected by a switch.
