Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker mounted on audio equipment, and more particularly, to a structure of a speaker frame in which a speaker frame is formed integrally with a structure constituting the audio equipment.

[0002]

2. Description of the Related Art Sound equipment such as radios and stereos,
2. Description of the Related Art In a video and audio device such as a television, a speaker mounted on the device is conventionally mounted on an exterior cabinet body using a screw, a spring body, an adhesive, or the like.

FIG. 5 shows a structure in which a speaker 35 is attached to the cabinet main body 30 by screws 38.
That is, the front wall 31 of the resin-made cabinet body 30
A plurality of bosses 32, 32,...
Are integrally formed, and a plurality of through holes 3 formed in the frame 36 of the speaker 35 are formed in the bosses 32, 32,.
Are screwed into the bosses 32, 32,... Through the through holes 37, 37,. Is fixed to the cabinet body 30.

FIG. 6 shows a structure in which the speaker 35 is attached to the cabinet main body 30 by a long spring body 43. That is, a groove 41 for fitting the frame 36 of the speaker 35 is formed on the back side of the front wall 31 (which may be a bottom wall in a television or the like) of the cabinet body 30 made of resin. A pair of hook-shaped locking pieces 42, 42 are arranged facing each other on both sides in the up-down direction or the left-right direction (in FIG. 6, both sides in the up-down direction). Then, the frame 36 of the speaker 35 is fitted into the concave groove 41, and thereafter, both ends 43 a, 43 b of the curved spring body 43 are inserted and locked into the hook-shaped locking pieces 42, 42, thereby forming the spring body 43. The speaker 35 is fixed to the cabinet body 30 by the elastic restoring force.

[0005]

However, the screw 3
8, the speaker 35 is attached to the cabinet body 30 by using a mounting member such as a screw 38, and when the screw 38 is insufficiently screwed or the screw 38 is loosened due to long use, the speaker 38 There has been a problem that the 35 itself vibrates to generate a so-called chatter sound.

In the case of the structure in which the speaker 35 is attached to the cabinet main body 30 by the elongated spring body 43, an attaching member such as the spring body 43 is required, and the hook-shaped locking portions 42 of the spring body 43, 42 is insufficiently inserted into the spring body 4 or the spring body 4
When the elastic force of the speaker 3 decreases, there is a problem that the speaker 35 itself vibrates and a so-called chatter sound is generated.

[0007] In the method of directly attaching to the cabinet body with an adhesive, a sufficient adhesive force may not be obtained depending on the amount and the method of application of the adhesive. 35
The vibration itself causes so-called chattering sounds,
In some cases, there was a problem of falling off. The present invention has been made to solve such a problem, and its purpose is to reduce costs by reducing members such as screws, spring bodies, and adhesives, and to reliably prevent chattering of speakers. To provide a speaker frame that can be used.

[0008]

According to a first aspect of the present invention, there is provided a speaker frame including a speaker frame, wherein the speaker frame is integrated with a structure constituting the audio device. It has been molded into. In the speaker frame according to a second aspect of the present invention, the frame of the speaker is formed integrally with a cabinet body for exterior of the audio equipment. Further, in the speaker frame according to the third aspect of the present invention, the speaker frame is formed integrally with a frame body holding the circuit board.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the speaker frame of the present invention. FIG. 1 is a front view of a cabinet main body, and FIG. 2 is a cross-sectional view taken along line AA in FIG. An example is shown in which a speaker frame is formed integrally with a cabinet body for an exterior of a television.

The cabinet body 1 for the exterior of a television is
An opening 3 for mounting a cathode ray tube (not shown) is formed in the front wall 2, and an opening 4 for mounting a display and operation panel (not shown) is formed below the opening 3. Laterally, a frame 11 constituting the speaker 10 is formed by integral molding.

That is, an opening 5 having a shape conforming to the outer peripheral shape of the speaker 10 is formed beside the opening 4, and the arm rods 12, constituting the frame 11 are formed from four corners of the opening 5.
.. Are extended rearwardly inclining toward the center axis L1 direction of the opening 5, and the extending distal ends of these arm rods 12, 12. It has a continuous structure. A magnet 14 is attached to the rear side of the flange plate portion 13, and the cone paper 1 is mounted on the front side of the frame 11.
5 and the grill 16 are attached to form the speaker 10.

That is, the cabinet body 1 is integrally formed of a synthetic resin. Simultaneously with the formation of the cabinet body 1, the frame 11 of the speaker 10 is integrally formed of a synthetic resin. In the above embodiment, the frame 11 is connected to the front wall 2 of the cabinet body 1.
However, the speaker 10 may be disposed downward on the bottom wall 6 of the cabinet body 1.

FIGS. 3 and 4 show another embodiment of the speaker frame of the present invention. FIG. 3 is a plan view of the frame.
FIG. 4 is a cross-sectional view taken along the line BB in FIG. 3 and shows an example in which the speaker frame is formed integrally with a frame body that holds a circuit board. TV circuit boards are large,
In order to secure the mounting strength, it is usually attached to the cabinet body while being held by the synthetic resin frame 21. In the present embodiment, a speaker frame is formed on the frame 21.

That is, the frame 21 has an opening 23 for holding a circuit board 22 for video and audio processing, and holds a circuit board 24 for power supply beside the opening 23. Opening 25 is formed,
In front of the opening 25 (corresponding to the front side of the cabinet body), the frame 11 constituting the speaker 10 is formed by integral molding.

That is, the speaker 10 is positioned in front of the opening 25.
An opening 26 having a shape corresponding to the outer peripheral shape of the opening 26 is formed, and arm rods 12, 12,... Constituting the frame 11 are directed from the four corners of the opening 26 toward the central axis L2 of the opening 26. The arm rods 12, 12
The structure is such that the extended distal end portion of... Is continuously connected by an annular flange plate portion 13. Then, a magnet 14 is attached to the upper side of the flange plate portion 13, and a cone paper 15 and a grill 16 are attached to the lower side of the frame 11 to provide a speaker 10.
Is formed.

That is, the frame 21 is integrally formed of a synthetic resin, and simultaneously with the formation of the frame 21, the frame 11 of the speaker 10 is also integrally formed of a synthetic resin. In each of the above embodiments, the configuration in which the speaker frame is formed integrally with the cabinet body 1 or the frame body 21 holding the circuit board is described. However, the speaker frame is not limited to the cabinet body 1 or the frame body 21 and may be made of resin. If there is a structure formed by the above, it is possible to form the speaker frame integrally with the structure.

[0017]

According to the speaker frame of the present invention, in an audio equipment having a speaker, the speaker frame is
Since it is configured so as to be integrally formed with the structure constituting the audio equipment, mounting members such as screws, springs, and adhesives are not required, so that the number of parts can be reduced, and the cost can be reduced. In addition, since the frame is formed integrally with the structure, there is no variation in the mounting strength of the speaker, and a constant and sufficient strength can be obtained. Since there is no such concern, no rattling sound of the speaker is generated.
