Detailed Description of the Invention TECHNICAL FIELD OF THE INVENTION

The present invention relates to a sound collector and a mobile phone equipped with the same, which are suitable for use in a place where external noise is severe.

[0002]

2. Description of the Related Art In recent years, with the progress of technological development in various aspects such as high integration of semiconductor integrated circuits, high-density mounting technology of parts, and development of high-performance batteries, various electronic devices have been made smaller and higher in size. Performance is rapidly increasing. In particular, along with flat displays, mobile phones, which have been a dream for many years for many people, are rapidly spreading due to the high convenience of being able to contact anytime, anywhere.

[0003]

By the way, although the mobile phone is used in various places, there is an inconvenience that the voice is hard to hear in a place where the surrounding noise is large. It may be possible to make it easier to hear by increasing the voice output, but this increases power consumption. Since the mobile phone is driven by the built-in battery, its power supply capacity is limited. Therefore, if the power consumption for voice output is increased, a new problem arises that the standby time becomes shorter and the communicable area becomes narrower.

For a mobile phone whose greatest feature as a product is that it can be used anytime and anywhere, its performance should not be evaluated simply by the presence or absence of various functions, but also the long and short standby time and the call. The size of the feasible area is also important. Although high-performance batteries such as lithium-ion batteries have been developed in recent years, the miniaturization of mobile phones is progressing, and accordingly, further miniaturization of batteries is also required. For this reason, the situation is such that a large increase in power supply capacity cannot be expected. Therefore, it has been required to make it easy to hear the voice without increasing the power consumption.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a sound collector which facilitates hearing of voice and a mobile phone having the same.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 is detachably held in an earpiece of a mobile phone body, and collects a voice output from the earpiece. A sound collector for collecting the sound, a plate-shaped base portion, a sound collecting portion formed in a conical shape substantially at the center of the base portion, and having a through hole for collecting sound at the conical top portion; An inverted L that is connected to the upper end of the mobile phone body and forms a U-shape with the base part, sandwiches the mobile phone body, and holds the sound collecting part in a state of being applied to the earpiece of the mobile phone body. It is characterized in that it is composed of a character-shaped holding member, and that the holding member is formed narrower than the lateral width of the base portion.

The invention according to claim 2 relates to a mobile phone, and is characterized by including the sound collector according to claim 1.

[0013]

The operation of the present invention will be described. If the surrounding noise is loud and it is difficult to hear the sound,
The sound collector is mounted on the mobile phone body by the mounting means. This mounting is possible by holding the main body housing of the mobile phone by the holding member.

In this mounted state, the rear side opening of the sound collecting hole of the sound collecting means is directed to the earpiece. Therefore, the sound output from the earpiece is collected by the sound collection hole and is output from the front surface side opening portion without spreading to the surroundings. The sound collecting hole can be more efficiently collected by making the back surface side opening larger than the front surface side opening.

In this case, if this front surface side opening is provided on the top of the conical projection projecting to the surface side of the sound collecting means, the top of the projection (that is, the front surface side opening) is the ear. Has been inserted into the hole (at least closer to the ear). Therefore, the sound output from the front surface side opening reaches the ear more efficiently. Further, when the protrusion is inserted in the ear, ambient sound is blocked by the protrusion. Therefore, even if the ambient noise is large, the voice can be easily heard.

If the sound collector is attached more positively by the connected portion provided on the main body of the telephone and the connecting portion provided on the sound collector, both can be fixed completely. The state becomes more stable. For example, the fitting protrusion provided as the connecting portion may be fitted into the fitting hole formed as the connected portion.

The details will be described below. The sound collector 1 is provided with a sound collecting portion 3 having a conical shape at a substantially center of a base 2 having a substantially rectangular plate shape. The tip of the sound collecting unit 3 (the lower end in FIG. 1A) is thinner than the opening of the human outer ear. In addition, a sound passage hole 4 is formed in the sound collecting portion 3 so as to extend therethrough. This sound hole 4
Expands in a taper shape as it goes to the back side, and its diameter is largest at the opening on the back side (upper side in FIG. 1C).

A sandwiching portion 5 having an inverted L-shape is provided on the rear side of the upper end of the sound collector 1, and when viewed from the side, the sound collector 1 as a whole is U-shaped. (Fig. 1 (c)). It should be noted that the base portion 2 and the sandwiching portion 5 are arranged such that, when the sound collector 1 is attached to the mobile phone body, the earpiece of the mobile phone body is located at the center of the sound passage hole 4 when viewed from the front side. The dimensions are set. Also, the base 2

Therefore, it is possible to prevent ambient sounds from coming into the ears. on the other hand,
The sound output from the earpiece 56 is collected by the sound passage hole 4 and is emitted from the front opening (the tip opening of the sound collecting unit 3) without spreading to the surroundings. Since the tip of the sound collecting unit 3 is inserted into the ear (outer ear), this sound reaches the ear directly. Therefore, the voice output from the mobile phone can efficiently reach the user's ear.

As described above, according to the sound collector of this embodiment, it is possible to block ambient sound, prevent the sound output from the earpiece from spreading, and efficiently reach the ear. Because it is possible, it is easy to hear the voice. Also,
Its mounting is also easy.

In addition to this, since they are mounted by a dedicated connecting and fixing mechanism (the engaging hole 30, the engaging claw 36), both are firmly connected and fixed. Moreover, since the shape of the sound collector 31 (particularly, the base portion 2b) is designed specifically for the mobile phone body 20, the mounted state is more stable, and the sound collection of the mobile phone body 20 and the sound collector 31 is more stable. High sense of unity. Therefore, the sound collector 31 does not come off or move out of position during use.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Also included in the present invention. For example, the first
In the embodiment, the sound collector 1 is attached to the mobile phone body by utilizing the elasticity of the holding portion 5, but the mechanism for attaching is not limited to this. For example, as shown in FIG. 9, a belt 12 may be provided and worn by this. In this case, it is preferable to employ a rubber belt or the like having elasticity as the belt 12.

Since the main body of the mobile phone is generally long in the vertical direction (the direction of the antenna), the belt 12 has the front surface 51, the side surface 53 and the back surface 54 of the mobile phone main body as shown in FIG.
It is preferable to provide it on a portion that is wrapped around Alternatively, as shown in FIG. 11, the belt 12 may be divided into two pieces, a belt piece 12a and a belt piece 12b, and surface fasteners 13a and 13b may be provided at the ends thereof.
In this configuration, as shown in FIG. 12, since the length of the entire belt can be adjusted by the surface fasteners 13a and 13b, the belt pieces 12a and 12b need not have elasticity. Since the whole sound collector is not bulky in such a configuration in which the belt is used for mounting (FIGS. 9, 10, 11, and 12), it is advantageous in terms of storage in a bag or the like when not mounted.

In the above-described third embodiment, the sound collector 3
1 and the mobile phone body 20, the engaging hole 30 and the engaging claw 3
6 was connected and fixed. However, a specific mechanism for connecting and fixing the both is such a configuration (engagement hole 3
0, the engaging claw 36) is not limited to,
A surface fastener or a snap mechanism (fitting protrusion / fitting hole) may be used. Further, the specific connecting position is not limited to the back surface, but may be connected at the front surface portion, the upper surface portion or the side surface portion. Examples in which such a configuration is adopted are shown in FIGS. 13, 14, 15, and 16.

FIG. 13 shows an example in which fitting holes 39 are provided in the back surface of the base portion 2c and the front portion 21 of the mobile phone body 20 which are formed in a substantially quadrangular plate shape so that they are connected and fixed. FIG. 14 shows a mounting state when such a configuration is adopted. In this case, it is not preferable that the mobile phone body 20 has a protrusion other than the operation switch. Therefore, as in the example of FIG. 14, it is preferable to install the fitting hole 39 on the front face 21 side and the fitting protrusion 40 on the base 2 side. With such a configuration, the sound collector can be made extremely compact. A hook-and-loop fastener may be used instead of this snap mechanism. However,
The surface fastener requires a certain area to obtain a sufficient joining force. However, it is not easy to secure such an area in a mobile phone that has been downsized, particularly in the front portion 21 where a large number of display panels 27, operation switches 28 and the like are arranged. On the other hand, the snap mechanism need only be provided with the fitting protrusion 40 and the fitting hole 39, and the occupied area thereof can be small. Therefore, to connect and fix the front portion 21, it is preferable to use the snap mechanism rather than the hook-and-loop fastener.

FIG. 15 shows the upper end portion 2 of the mobile phone body 20.
2 is an example in which the surface fastener 41 is connected and fixed. FIG. 16 shows a mounting state when such a configuration is adopted. In this case, the base 2d
Is formed in an inverted L shape with its upper end projecting to the rear side, and a surface fastener 41a is provided on the lower side surface of this projecting part. On the other hand, the top end portion 22 of the mobile phone body 20 is provided with a surface fastener 41b to be joined thereto. Also in this case, a snap mechanism can be used instead of the hook-and-loop fastener.
