Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a function of an acoustic coupler for transmitting / receiving information via a telephone line using a telephone handset (receiver) as connection means for electroacoustically converted data. Related to a coupler device.

[0002]

2. Description of the Related Art Since such a coupler device is acoustically connected to a telephone handset, the coupling with the handset is made surely and well in order to reduce the influence of ambient noise. It must be made. However, since there are various types of handset handsets, it is necessary to provide a coupler device that can be adjusted and coupled according to each type. Therefore, conventionally, various configurations of acoustic coupler structures have been proposed.

FIG. 14 schematically shows an example of a conventional acoustic coupler structure provided in a so-called portable terminal device. In the figure, 51 is an arm portion, 52 is a slide plate, 53 is a support body containing a microphone 53a, 54 is a torsion spring, 55 is a speaker, 56 is a locking claw, 57 is a main body of a portable terminal device, and 58 is a telephone. Handset. FIG. 7A shows a state at the time of storage, and FIG. 7B shows a state at the time of use. The handset 58 in both figures
It is drawn so as to compare the arrangement relationship with.

In order to set the state shown in FIG. 2A from the state shown in FIG. 2A to the state shown in FIG. 2B, the support 53 is manually moved to the left in FIG. 56
Is released, the torsion spring 54 causes the arm 51 and the support 53 to hop up about the rotation shaft 51a. Then, the slide plate 52 is adjusted in accordance with the pitch between the earpiece 58a and the mouthpiece 58b of the handset 58 to be used, and is moved to the left and right in the figure, so that the support 53
Is placed in contact with the earpiece 58a, and the mouthpiece 58b is placed so as to cover the upper side of the speaker 55, and is connected in close proximity.

At this time, since the arm portion 51 and the support member 53 are formed of an elastic member, the arm member 51 and the support member 53 are appropriately curved, and the support member 53 is brought into close contact with the earpiece 58a with an appropriate pressure, thereby being affected by external noise. Is reduced. The speaker 55 is fixed at a predetermined position on the main body 57. In this case, the structure is not in close contact with the mouthpiece 58b. This is because the transmitting side is rarely affected by external noise. Finally, when transmission or reception is completed, the slide plate 52 is moved to the right in the figure, and the arm 51 and the support 53 are
Is fixed to the main body 57 so as to be in the storage state shown in FIG.

[0006] As another example, Japanese Utility Model Application Laid-Open No.
As described in Japanese Patent No. 727, a data terminal device is disclosed in which a receiving unit having a receiving acoustic coupler is detachably attached to a main body to which a transmitting acoustic coupler is attached. Alternatively, Japanese Patent Laid-Open No. 62-20095
As described in Japanese Patent Application Publication No. 1 (1999) -1995, there is disclosed an acoustic coupler having a configuration in which an electroacoustic transducer is supported at both ends of a telescoping telescopic rod and pressed against a handset. Further, as described in Japanese Utility Model Publication No. 3-6055, the mouthpiece receiver and the earpiece receiver are connected by a leaf spring, and these can be fixed at an arbitrary position so that they can be fitted to the handset. An acoustic coupler handset receiver is disclosed.

[0007]

However, in the configuration shown in FIG. 14, the pitch between the earpiece 58a and the mouthpiece 58b of the handset 58 to be used is changed every time the apparatus is set to the state of use. In addition, the pitch between the support 53 as the earpiece receiver and the speaker 55 as the mouthpiece receiver must be adjusted. Usually, the handset to be used is often limited to a pay phone or a user's own mobile phone, but even in such a case, it is very inconvenient considering that the pitch must be adjusted every time. . It is desirable that once the pitch is adjusted, it can be used as long as the shape of the handset does not change.

The arm 51 and the support 53 shown in FIG.
Is formed of an elastic member, the curved state at the time of use is maintained as it is, so-called a habit may be formed, and it becomes very difficult to store it in the main body 57, and it protrudes from the main body 57 in the stored state. It will be lost. Also, in the configuration described in each of the above publications, similarly, in terms of operability or storage,
We still need to improve.

[0009] Further, portable terminal devices for creating, transmitting and receiving e-mails, which have become widespread in recent years, are manufactured for the purpose of being able to be used easily and simply in places other than the original business place, and are easy to carry. Compactness, simplicity of device operation during use, securing of setting reliability and reliability, and performance maintenance of the transmitting / receiving section (here, the acoustic coupler portion) when not in use are required. However, such a portable terminal device is usually mixed with other office supplies and documents in a bag or the like, and is often carried together with the device. In severe cases, there are many factors that cause damage to the apparatus, such as collision with other hard office supplies.

[0010] In particular, if the transmission / reception unit is damaged, it is fatal and the original function of the portable terminal device is impaired. In addition, such a mobile terminal device needs to use a public telephone or a telephone handset (receiver) provided at a destination or a mobile phone as a medium as a transmission / reception means. In addition to the characteristics, there are various types, and the pitch and shape of the mouthpiece and the earpiece, which are the contact points of transmission and reception, are various, so that a structure that can appropriately cope with them is required. To this end, an acoustic coupler structure serving as a transmission / reception contact point on the portable terminal device side is a particularly important factor. Furthermore, the acoustic coupler part is not exposed on the exterior surface,
The fact that the structure is not easily damaged is also a very important factor.

SUMMARY OF THE INVENTION In view of the above problems, the present invention can flexibly and easily cope with telephone handsets having a variety of shapes, and also has a function to match the shape of the handsets. It is an object of the present invention to provide a coupler device that can minimize the number of adjustments and that is not easily damaged by external force.

6 or 8, reference numeral 11 denotes a substantially ring-shaped microphone rubber which is a contact part with the earpiece, 12 denotes a substantially disk-shaped microphone case fitted around the inner periphery of the microphone rubber 11, and 15 denotes a microphone case. 12 combined with the lower surface,
This is also a substantially disk-shaped microphone case. Microphone case 1
A substantially cylindrical casing 15a extending upward is provided at the center of the upper surface of 5, and a substantially columnar microphone 14 is fitted therein. The lead wire 16 extending from the microphone 14 is taken out of the cutout 15b of the casing 15a to the outside, and passes through the inside of the coil spring 17. Here, the lead wire 16 is a shielded wire so as not to pick up external noise.

A substantially disk-shaped microphone filter 13 for protecting the microphone 14 is provided on the upper surface of the microphone 14, and these are sandwiched and attached between the microphone cases 12 and 15. At this time, a hook 17 a provided at one end of the coil spring 17 is fitted and attached to the outer periphery of the casing 15 a of the microphone case 15, and the coil spring 17 is also sandwiched between the microphone cases 12 and 15. Finally, the microphone case 12 is fastened and fixed to the microphone case 15 with screws 25. The microphone 14 catches sound through a hole 12 a provided in the center of the microphone case 12.

As described above, the microphone rubber 11 is a contact part with the earpiece, and is a very important part for accurately and reliably transmitting data. Therefore, the microphone rubber 11 is flexible and deteriorates depending on aging. Use a material which is easy to process with a mold, such as urethane rubber or silicon rubber, which is a safe material. As shown in FIG. 6, the microphone case 12 is attached to the microphone case 15 so that the microphone rubber 11 can be freely fitted to the microphone case 12 and can be easily removed and replaced when the microphone rubber 11 is damaged. Groove 1 formed around when assembled
5c, a lower inner peripheral portion of the microphone rubber 11 is fitted and fixed.

At this time, an internal space 11a is formed between the microphone rubber 11 and the microphone case 12 around the entire periphery of the microphone rubber 11, thereby increasing the flexibility of the microphone rubber 11.
Adhesion with the earpiece is also promoted. Further, as shown in FIG. 7, in the present embodiment, a projection 27 is provided in the storage section D of the bottom cabinet 22 forming the housing C, and when the earpiece receiving section 5 is stored in the main body 10, the microphone case 12 is closed.
The projection 27 is brought into contact with the bottom rubber 22 to prevent the microphone rubber 11 from contacting the bottom cabinet 22. As a result, even if the storage state is kept long,
It is possible to prevent the microphone rubber 11 from being deformed.

Referring again to FIG. 6 or FIG.
Reference numeral 1 denotes a substantially thick plate-like arm attached to the bottom cabinet 22 side. A pair of flip springs 18 are fitted into a pair of fixing portions 21a provided at one end of the arm 21, respectively. It is sandwiched between the parts 20 and 21 from above and below, and attached and fixed.

At this time, a hook 17b provided at the other end of the coil spring 17 is connected to a pair of fixing portions 21 of the arm portion 21.
The coil spring 17 is also fitted and mounted on the outer periphery of a substantially columnar projection 21b extending upward from
It is sandwiched between 0 and 21. The lead 16 passing through the inside of the coil spring 17 is passed through one flip spring 18, taken out to the outside, and guided to the inside of the bottom cabinet 22. Finally, the arm section 20 is fastened and fixed to the arm section 21 with screws 26.

As shown in FIG. 8, the flip spring 1
A substantially prismatic projection 18a extends from one end of each of the base cabinets 8, and is inserted and fitted into square holes 22a formed on the left and right sides of the storage unit D at the end of the bottom cabinet 22, respectively. The flip spring 18 has a function as a rotation axis of the earpiece receiver 5. When the flip spring 18 relatively rotates the main body and the projection 18a by an external force, the flip spring 18 attempts to return to its original state by an elastic force when the amount of rotation is up to a predetermined angle. It is a commercially available part (Kato Spring Co., Ltd.) with a structure that tries to rotate by a certain angle by elastic force.
In recent years, it has been frequently used for a lid portion of a mobile phone.

Further, in order to reliably maintain the positional relationship between the earpiece 8a of the handset 8 and the earpiece receiving portion 5 as shown in FIG. Rubber 19 is attached to the upper surface of arm 20. As a result, the screw 26 can be covered and concealed, so that the appearance is improved and the user cannot easily disassemble it, which is also effective for maintaining the function of the apparatus.

As shown in FIG. 8, an arm 23 slidably fitted to the back surface of the bottom cabinet 22 and having a function of hopping up the earpiece receiving portion 5 is provided. The hop-up knob 7 communicates with the hop-up knob 7 and has a substantially U-shape. The operation point 23a at the free end of the hop-up knob 7 acts on the earpiece receiver 5 by operating the hop-up knob 7, and the hop-up knob 7 It is something to be up. Arm 23
Is attached, the hop-up knob 7 projects outward from a relief hole 22b provided on the surface of the bottom cabinet 22.

By the way, the microphone cases 12, 15,
The arms 20 and 21 are formed of a thermoplastic resin. The hooks 17a and 17b formed at both ends of the coil spring 17 have an effective shape for preventing the earpiece receiving portion 5 from rotating freely. On the other hand, the coil spring 17 has a function of allowing the earpiece receiving portion 5 to flexibly and flexibly move while moving, and as described above, the coil spring 17
The lead wire 16 which is a conductive wire as a transmitting member for signal transmission can be passed through the inner diameter space of the above, so that the protection can be performed and the wire processing becomes very easy. It is possible to provide a small device.

FIG. 9 is an explanatory diagram of the mechanism by which the earpiece receiver 5 hops up. (A) of the figure is a plan view, and (b) is a side view. As shown in the figure, when the coupler device according to the present embodiment is not used, the earpiece receiving portion 5 is normally housed in the bottom cabinet 22, and the hop-up knob 7 and the arm 23 communicating therewith are provided with a spring. 24 is normally slid to the right in the drawing, and its action point 23 a is in a state not in contact with the arm portion 21. When the hop-up knob 7 is moved to the left in the drawing at the time of use, the arm 23 also slides to the left as shown by the arrow in the drawing, and the action point 23 a comes into contact with the arm 21.

Further, the arms 20 and 21 indicated by broken lines in FIG. 3B are lifted by the action of the slope forming the action point 23a, and the earpiece receiver 5 pulls the flip spring 18 through the rotation axis (flip hinge). ) And rotate counterclockwise in the figure. In the case of the present embodiment, when the earpiece receiver 5 is opened about 15 degrees with respect to the bottom cabinet 22, the earpiece receiver 5 is further automatically rotated 120 degrees due to the characteristics of the flip spring 18, that is, the earpiece receiver 5 is turned to the bottom. It opens up to 135 degrees with respect to the cabinet 22.

Further, it is possible to open the earpiece up to 180 degrees as shown by the solid line, depending on the load when an earpiece (not shown) is set. In this case, flip spring 18
On the contrary, an urging force to rotate clockwise works. At the time of storage, the earpiece receiver 5 is set at about 1
If it is manually returned so that it is within 5 degrees, it will be in the state of storage shown in FIG.

As a characteristic of the flip spring, when the flip spring itself is rotated by an external force from a steady state, a predetermined rotation angle required until the flip spring is further rotated is actually about 30 degrees. Yes,
There is a margin of 30-15 = 15 degrees to rotate clockwise further than the stored state in FIG. As a result, during storage, the earpiece receiving portion 5 is in contact with and fixed to the bottom cabinet 22 while being prevented from being lifted while being urged. Note that the predetermined rotation angle of the flip spring is not limited to the present embodiment, but may be selected for its characteristics or for adjusting the relative angle when the flip spring is attached to the bottom cabinet 22 or the arm 21. Can be changed.

Further, the present invention is not limited to the configuration using such a flip spring. For example, the earpiece receiving portion 5 is always biased in a hop-up direction,
Of course, it is also possible to adopt an orthodox configuration in which some engagement portion works to hold it during storage, and disengage the engagement when used so that it hops up and stands by. Alternatively, a configuration using a simple method, such as raising the earpiece receiver 5 directly by hand, may be used.

FIG. 10 is an exploded perspective view showing the structure of the mouthpiece receiver 6 and its peripheral components. As shown in FIG.
The mouthpiece 8b and the mouthpiece receiver 6 of the handset 8 as shown in FIG.
In order to reliably maintain the positional relationship of, a non-slip rubber 31 that prevents slippage due to a large frictional resistance to the mouthpiece,
It is stuck on the step 22c on the bottom cabinet surface.
The mouthpiece receiving portion 6 (more precisely, a protrusion 36a of the speaker housing 36 described later) is inserted into each of these portions, and provided with slidable slots 31a and 22d, respectively.

Reference numeral 37 denotes a substantially disk-shaped speaker, which has a function of converting an electric signal based on the created data into an audio signal. The lead wire 32 extends laterally from the speaker 37. A substantially flat plate-like member 36 located above the speaker 37 is a speaker housing, and a substantially disk-shaped protrusion 36a is provided on the upper surface of the speaker housing. . The upper surface of the protrusion 36a is concave so that the mouthpiece 8b is easily stabilized when the mouthpiece 8b is closely joined, and a large number of holes 36b for emitting sound from the speaker 37 are formed. Note that, depending on the shape of the mouthpiece 8b of the target telephone, the upper surface of the protrusion 36a does not necessarily need to be concave, and may be a flat or convex surface in a corresponding form.

Further, here, a plurality of projections 36c are arranged in a short linear shape substantially perpendicular to the sliding direction of the mouthpiece receiving portion 6, and these do not project above the upper end of the projection 36a. The height is kept low. This projection 36c
Has an effect of preventing the finger from slipping when the mouthpiece receiver 6 is manually slid, thereby improving the operability when setting the handset. The protrusion 36
c is not limited to the shape in the present embodiment, but may be any of various shapes such as a round shape and a square shape, as long as it has a finger slip-preventing effect.

The speaker housing 36 is supported from both side surfaces and the lower surface in the figure by long plate-shaped speaker pressing plates 38 and 39, and is attached to the rear surface of the bottom cabinet 22 by screws 40. At this time, a lock concave portion 38a is continuously formed on the side surface of the speaker pressing plate 38 so as to face a lock convex portion 36d provided on one side surface of the speaker housing 36, and the lock convex portion 36d is formed on any of these. Is engaged, whereby the speaker housing 36 and the mouthpiece receiving portion 6 are fixed at an arbitrary sliding position.

The configuration for adjusting the slide position is not limited to the one in the present embodiment. For example, the arrangement relationship between the lock convex portion and the lock concave portion may be exchanged, It may be configured such that it can be adjusted steplessly by using force or the like. Further, according to the configuration for adjusting the slide position of the mouthpiece receiving section 6 as described above, particularly when the handset to be used is limited,
Once adjusted, it can be used with the slide position the next time, which is convenient.

Further, as shown in the figure, between the speaker housing 36 and the bottom cabinet 22, hide seats 33, 34, 35 are disposed so as to overlap each other. This is to shut off the inside and the outside of the device so that the front and back sides of the cone of the speaker 37 do not acoustically interfere with each other. The protruding portion 36a of the speaker housing 36 is inserted into each of the hide seats, and the slidable elongated hole 33 is provided.
a, 34a and 35a are provided respectively.

The length of each hide sheet in the sliding direction is gradually reduced in a stepwise manner, and furthermore, bent portions 33b, 34b and 35b are provided at the front and rear ends, respectively. Thereby, in a state where the respective hide sheets are superimposed, the relative sliding stroke is regulated within the range of the difference in length by the contact between the bent portions,
No matter where the speaker housing 36, that is, the mouthpiece receiver 6, is slid, the inside of the device always has the effect of being closed to the outside. Further, according to such a bent portion, the effect of increasing the strength of each hide sheet can be obtained. However, the configuration in which the bent portion is provided is not limited. For example, a configuration in which a contact portion that restricts the slide stroke may be provided in each slide sheet may be used.

The number of the hide sheets is not limited to the three shown in the present embodiment, and an effective number of sheets which can obtain the effect reliably and are selected as required. For example, as shown by a two-dot chain line in FIG.
1 may be further inserted. In addition, as a material of the hide sheet, a light-weight P
A resin material such as an ET material or a PVC material is preferable. In any case, a configuration that smoothly follows the sliding movement of the speaker housing 36 and that can reliably shut off the inside and the outside of the device is required.

In this sense, the configuration is not limited to the configuration in which the hide sheets are overlapped as in the present embodiment. For example, a configuration in which a shutter is provided to perform winding and rewinding may be used, It may be configured to expand and contract. Alternatively, it is also possible to adopt a configuration in which only one hide sheet is slid, but in this case, the device becomes extra long by the stroke.

FIG. 11 is a diagram showing a change in the sliding position of the mouthpiece receiver 6 depending on the length of the handset 8 to be set. FIG. 7A shows a case where the transmitter / receiver 8 is the longest usable, that is, a case where the pitch between the earpiece 8a and the mouthpiece 8b is the longest with respect to the coupler apparatus of the present embodiment. FIG. 3B similarly shows the shortest case.
In any case, the earpiece receiver 5 is closely connected to the earpiece 8a, and the mouthpiece receiver 6 is sufficiently connected to the mouthpiece 8b. In this way, a flexible response is possible according to the length of the handset 8.
