In addition, two air holes 6a and 6b are formed in the frame 5 for air circulation, and the air holes 6a and 6b have a structure of the engaging jaw 9a of the outer walls 8a and 8b. The internal space formed by the diaphragms 13a and 13b coupled to 9b is communicated with the outside, i.e., the opposite side or side of the frame 5.

In particular, the height of the frame 5, i.e., the height of the outer walls 8a and 8b, does not require a space for the vibration of the yoke 1, so that the vibration of the diaphragm 13a and 13b that can perform the function of a speaker or a receiver is performed. The height alone is enough. Thus, the unnecessary thickness of the frame 5 is reduced.

In the seating space (3a) (3b) of the yoke (1) integrally molded in the center of the frame (5), the magnetic magnet (10a) (a spaced apart from the side wall (2a) (2b) of the yoke 1 by a predetermined distance ( 10b) and plates 11a and 11b are seated. In other words, a permanent magnetic loop is formed that extends into the magnetized magnets 10a and 10b and the bottom of the yoke 1, the side walls 2a and 2b of the yoke 1 and the plates 11a and 11b. It is. In particular, by increasing the diameter of the plate (11a) (11b) than the magnetic magnet (10a, 10b) it can be made smoothly the flow of the magnetic force line.

The diaphragm 13a, 13b for vibrating up and down to form a sound pressure is horizontally coupled to the coupling jaw 9a, 9b of the outer wall 8a, 8b formed above and below the frame 5, and the diaphragm On the bottom face of the face (13a) (13b), that is, the face toward the frame (5), an annular coil wound to form a magnetic force opposed to the magnetic force of the magnetic magnets (10a, 10b) by an externally driven drive power ( 12a, 12b are attached, and the coils 12a, 12b have a lower end of the coils 12a, 12b with sidewalls 2a, 2b of the yoke 1 and a magnetic magnet 10a, 10b. It is supposed to come down to the space in between.

In addition to the diaphragms 13a and 13b, the engaging jaws 9a and 9b of the outer walls 8a and 8b are equipped with grills 14a and 14b having a plurality of through holes, and the diaphragms 13a and 13b. It can protect the internal configuration, including).

In order for the signal converters formed above and below the frame 5 to have different characteristics, the magnetic force of the magnetic magnets 10a and 10b formed above and below the frame 5 or the number of turns of the coils 12a and 12b, It is preferable that one or more of the elasticity indexes of the diaphragms 13a and 13b are differently set.

As such, a signal converter having both different characteristics, that is, a speaker and a receiver function, may be mounted on a cellular phone as shown in FIG. 8 to selectively perform a function of a speaker or a receiver according to the use or function of the cellular phone.

In other words, the operating principle of the speaker and the receiver having different characteristics is that the driving power is supplied to the coil 12a positioned at the top of the frame 5, and the pushing and pulling force formed between the coil 12a and the magnet 10a and the frame. The driving power is supplied to the coil 12b positioned at the lower end of the 5 so that the pushing and pulling forces formed between the coil 12b and the magnet 10b are different, so that the vibration widths of the diaphragms 13a and 13b, that is, the diaphragm This is because the sound pressure formed by the vibration of (13a) and (13b) changes.

In particular, the yoke 1 is fixed to the frame 5 to correspond to the driving power supplied from the outside, that is, it is possible to accurately reproduce the sound desired by the user.

5 to 7 show another example of the multi-function signal conversion apparatus according to the present invention, in which the yoke 21 integrally formed with the frame 25 is bent and molded into a single plate, and the upper and lower inner portions of the yoke 21 are illustrated. The seating spaces 23a and 23b for seating the magnetic magnet 30a and the plate 31a and the magnetic magnet 30b and the plate 31b around the side wall 22 formed by bending of the plate are provided. Each of them is formed, and the outer periphery of the yoke 21 is formed on a bent surface that can be integrally molded in the center of the frame 25.

Like the embodiment described above, the process of processing the yoke 21 can be reduced, and the production cost of the yoke 21 is significantly lowered. In addition, since the frame 25 and the yoke 21 are integrally formed, the yoke does not move while performing the speaker or receiver function so that the sound can be accurately reproduced.

In addition, the outer wall 28a having different radii as shown in the drawing is formed on the upper and lower outer edges of the frame 25 integrally formed with the yoke 21 in a state where the yoke 21 formed of one plate is located at the center. 28b) are formed, respectively, and engaging jaws 29a and 29b for engaging the diaphragms 33a and 33b are formed on the inner upper end of each of the outer walls 28a and 28b. Grilles 24a and 24b for protecting the configuration including the diaphragms 33a and 33b together with the diaphragms 33a and 33b may be sequentially coupled (attached) to the coupling jaw 29a and 29b. have.

In particular, the height of the frame 25, i.e., the height of the outer walls 28a and 28b, does not require a space for the vibration of the yoke 21, thereby suppressing the vibration of the diaphragms 33a and 33b that can function as a speaker or a receiver. The height alone is enough. Thus, the unnecessary thickness of the frame 25 is reduced. In addition, by placing two magnets and plates forming the speaker and the receiver on the same plane, the magnetic force of the external magnet can be maximized, and the signal converter can be greatly reduced in thickness.

In the seating spaces 23a and 23b of the yoke 21 integrally molded at the center of the frame 25, the magnetic magnet 30a and the plate 31a are spaced apart from the side wall 22 of the yoke 21 by a predetermined distance. And the magnetic magnet 30b and the plate 31b are respectively seated. In other words, a permanent magnetic loop is formed that extends between the magnetic and magnetic magnets 30a and 30b and the bottom of the yoke 21, the sidewalls 22 of the yoke 21 and the plates 31a and 31b. It is. In particular, by increasing the diameter of the plate (31a) (31b) than the magnetic and magnetic magnets (30a, 30b) can be a smooth flow of magnetic field lines.

The diaphragm 33a, 33b for vibrating up and down to form sound pressure is horizontally coupled to the engaging jaw 29a, 29b of the outer walls 28a, 28b formed above and below the frame 25, and the diaphragm is horizontally coupled. The bottom surface of the (33a) (33b), that is, the surface facing the frame 25 is wound in an annular shape to form a magnetic force opposed to the magnetic force of the magnetic and magnetic magnets (30a, 30b) by the external drive power supplied from the outside Jean coils 32a and 32b are attached, and the coils 32a and 32b have lower ends of the coils 32a and 32b with the sidewalls 22 of the yoke 21 and the magnetic and magnetic magnets 30a. It is supposed to descend to the space between 30b.

In addition to the diaphragms 33a and 33b, the engaging jaws 29a and 29b of the outer walls 28a and 28b are equipped with grills 34a and 34b having a plurality of through holes, and thus the diaphragms 33a and 33b. It can protect the internal configuration, including).

In order for the signal converters formed above and below the frame 25 to have different characteristics, the magnetic force and the coils 32a and 32b of the magnetic and magnetic magnets 30a and 30b formed above and below the frame 25 may be different. It is preferable that at least one of the number of turns and the elasticity index of the diaphragms 33a and 33b is set differently.

As such, a signal converter having both different characteristics, that is, a speaker and a receiver function, may be mounted on a cellular phone as shown in FIG. 8 to selectively perform a function of a speaker or a receiver according to the use or function of the cellular phone.

In other words, the operating principle of the speaker and the receiver having different characteristics is that the driving power is supplied to the coil 32a located at the top of the frame 25, and the pushing and pulling force is formed between the coil 32a and the magnetic magnet 30a. And the driving power is supplied to the coil 32b positioned at the lower end of the frame 25 and the vibration of the diaphragms 33a and 33b is different because the pushing and pulling forces formed between the coil 32b and the magnetic magnet 30b are different from each other. This is because the width, that is, the sound pressure formed due to the vibration of the diaphragms 33a and 33b is different.

In particular, the yoke 21 is fixed to the frame 25 to correspond to the driving power supplied from the outside, that is, it is possible to accurately reproduce the sound desired by the user.

Therefore, according to the present invention, unlike the conventional one, the signal converter does not perform the function of the vibrator but only the speaker and the receiver function, thereby eliminating the space for the vibration of the yoke, that is, the height, thereby minimizing the thickness of the signal converter. It can be reduced.

In addition, the present invention can be more accurately reproduced by configuring the integrated unit with the frame so that the yoke does not move when selectively performing the functions of the speaker and the receiver.

In addition, the present invention is to reduce the volume of the signal conversion device including the yoke, simplify the manufacturing process and lower the production cost of the signal conversion device by bending the yoke, which is the main component of the signal conversion device, by bending one plate.
