Abstract

PURPOSE:To stick a drive cone and a diaphragm together without eccentricity and the spreading nonuniformity of an adhesive agent by pressing the drive cone to the diaphragm by using Lorentz's force to be generated when a direct current voltage is impressed to a voice coil. CONSTITUTION:The direct current voltage of the same polarity and the same level is impressed to terminals 11 and 11. When the voltage is impressed in such a way, the direct current flows to voice coils 7 and 7 and by the operation of the current and a magnetic flux between yokes 5 and 5 and yokes 6 and 6, the Lorentz's force is generated respectively in arrow directions in the voice coils 7 and 7. The voice coils 7 and 7 are kept in a position where the Lorentz's force is balanced with the elastic force of dampers 8 and 8. Afterwards, when respective frames 12 and 12 of first and second vibration systems 1 and 2 are mutually joined, the adhering part of a drive cone 9 in the second vibration system 2 is pressed onto the upper surface of a diaphragm 3 where an adhesive agent 13 is applied. Then, the drive cone is adhered to the diaphragm 3 by the adhesive agent.

One end of the voice coil (7) is connected to the input side of the terminal (11) via the drive cone (9) pattern and one wire of the wire (10). Also, the other end of the voice coil (7) is connected to the terminal (11) via another pattern on the drive cone (9) and the other glue of the wire (IO).
connected to the ground side of the Here, the first vibration system (
1), and the diaphragm (3) are bonded together using the drive cone (9).
Since the top is open, work can be done freely, and therefore the diaphragm (3) can be bonded to the drive cone (9) of the first vibration system (1) without eccentricity. . However, the drive cone (9) of the second vibration system (2)
) and the diaphragm (3), join the frames j, (12) and (12) of the first and second vibration systems (±) and (to) from the state shown in Figure 1. After that, insert your finger through the opening of each frame (12) (12) and press each drive cone (9) (9) to release the drive cone (9) of the second vibration system (2). The diaphragm (3) must be bonded to the diaphragm (3). For this reason, workability is poor, and
Drive cone (9
) and the diaphragm (3), or the adhesive may not spread evenly on the adhesive surface of the drive cone. In such a case, the sound characteristics of the speaker deteriorate, and in severe cases, abnormal noise may be emitted from the speaker.

(c) Problems to be Solved by the Invention The present invention provides good adhesive workability between the drive cone and the diaphragm of each vibration system, and prevents the drive cone and the diaphragm from being eccentric. It is an object of the present invention to provide a method for assembling a twin drive speaker in which the drive cone is uniformly spread over the bonded portion of the drive cone.

(d) Lower stage for solving the problems In view of the above-mentioned problems, the assembly method of the present invention provides a method for assembling the first and second vibration systems when sandwiching the first vibration system and the second vibration system on a single vibration plate. A DC voltage was applied to the voice coil of each vibration system so that the two vibration systems were pressed against each other.

(E) Function The pressure force used to bond the drive cone to the diaphragm uses the electromagnetic force generated when a DC voltage is applied to the voice coil. Since such electromagnetic force uniformly urges the drive cone in the pressure contact direction, the positional relationship between the drive cone and the diaphragm may become misaligned at the contact M station, or the adhesive may not spread uniformly to the bonded part of the drive cone. No inconvenience will occur.

The voice coil (7) (7)i is maintained at a position where this Lorentz force and the elastic force of the damper (808) are balanced. In such a state, the motion of the voice coil other than in the direction of the arrow will be damped due to the interaction between the DC current and the magnetic flux 12.

After that, when the frames (12) (12) of the first and second vibration systems (±) and (left) are joined to each other, the adhesive part of the drive cone (9) of the second vibration system (left) is the adhesive (
13) is pressed against the top surface of the diaphragm (3) coated with the coating. At this time, each voice coil (7) (7) is pushed back in the opposite direction of the arrow by such pressure contact, but each voice coil (7) (7)
) still generates the Lorentz force in the direction of the arrow, so each drive cone (9) (9) comes to press against each other with the diaphragm (3) in between. Therefore, the adhesive part of the drive cone (9) of the second vibration system (2) is attached to the vibration plate (3).
It is pressed against the diaphragm (3) at the adhesive application position, and is bonded to the diaphragm (3) with this adhesive.

Note that since the Lorentz force generated in each voice coil (7) (7) is uniformly transmitted to each drive cone (9) (9), the drive cone (7) of the second vibration system (2)
The adhesive portion is uniformly pressed against the diaphragm (3) over the entire area. Therefore, the adhesive (13) is attached to the drive cone (9).
) spreads evenly over the adhesive area. In addition, since the pressure contact force of the drive cone (9) is gradient in this way, deviation between the drive cone (9) and the diaphragm (3) caused by an unbalanced pressure contact force occurs during bonding. do not. Furthermore, as described above, since the voice coils (7) (7) are braked from displacement in directions other than the pressure contact direction, each frame (12) (
12) and the drive cone (7) (7) is good < fL, the contact between each frame (12) (12) is
If the mounting accuracy is good, the drive cone (9) of the second vibration system (to) is bonded without being eccentric with respect to the vibration plate (3).

In addition, the level of the DC voltage applied to the terminals (11) (11) is higher than that of the drive cone (9) and the diaphragm (3).
The pressure contact force increases, and in a short time the drive and f-cone (
9) and the diaphragm (3) are effectively crimped, but if the pressure is too large, the voice coils (7) (7) may burn out. Therefore, the level and application time of the DC voltage applied to the terminals (11) (11) must be appropriately adjusted in consideration of the material of the adhesive, etc.

(G) Effects of the Invention According to the present invention, the drive cone is pressed against the diaphragm using the Lorentz force generated when the tit current voltage is applied to the voice coil, so there is no difference in the pressure contact force. Since no balance occurs, the drive cone and the diaphragm can be bonded without eccentricity and without uneven spread of the adhesive. Further, at this time, there is no need to insert fingers through the opening of the frame, which facilitates the assembly work.
