Abstract

PURPOSE: To provide a loudspeaker device with superior performance by which the transmission of vibration from the hook for mounting of a loudspeaker can be suppressed. CONSTITUTION: The loudspeaker device can be provided by which the resonance of a cabinet 1 by an acoustic wave radiated from the loudspeaker 4 can be suppressed by employing such constitution to form the hook 6 for mounting by extending one terminal of a reinforcing muntin 5 which connects two confronting faces of the cabinet 1 provided on the rear face of the loudspeaker 4 and also, provided with the superior performance to prevent the vibration of the loudspeaker 4 when it is mounted on another cabinet 3 from being transmitted as far as possible by forming the hook 6 for mounting by extending the reinforcing muntin 5 for which the vibration can be suppressed to a minimum.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker device provided with a hook for attachment to a cabinet to which a speaker is connected.

[0002]

2. Description of the Related Art Conventionally, as a method of mounting a speaker device on a wall surface or a side surface of another electronic device, for example, a television device, a mounting bracket is separately mounted on a side surface of a cabinet to which a speaker is coupled, and a wall surface or other member is mounted through this. In many cases, the hooks that are set with the above-mentioned mounting brackets are hooked to the cabinet of the above, or in the case of cabinets made of plastic molded products, the mounting hooks are pre-formed on the side of the cabinet and used for mounting. ing.

A conventional speaker device of this type will be described below with reference to the drawings. FIG. 2 is a front sectional view showing the structure of the above-mentioned conventional speaker device. In FIG. 2, reference numeral 1 denotes a cabinet provided on the rear surface of the speaker 4 and having the speaker 4 coupled to the front surface thereof, and 2 denotes the cabinet 1.
Attachment hooks 3 provided on the side surface of the cabinet are cabinets of other electronic devices (shown in cross section of essential parts).

The conventional speaker device configured as described above is configured so that it can be easily mounted by simply inserting the mounting hook 2 into the recess of another cabinet 3.

[0005]

However, in the above-mentioned conventional configuration, the sound wave radiated from the speaker 4 to the back causes the cabinet 1 to resonate, and the vibration is transmitted to the other cabinet 3 through the mounting hook 2 to cause this phenomenon. The loudspeaker 4 emits a larger sound wave and the cabinet 1 also has a larger resonance, and as a result, the mounting hook 2
However, there is a problem that a large vibration is generated and the vibration is transmitted to other cabinets 3.

In recent years, a CD-R that handles voice and music information
A personal computer for multimedia (hereinafter referred to as a personal computer) with a built-in OM is becoming widespread, and it is becoming common to attach an external speaker to such a personal computer body to enjoy voice or music information. In such a field, in the speaker device having the conventional configuration as described above, vibration when a sound wave is generated is easily transmitted to the personal computer body, and a CD-ROM or a hard disk, which is a data input / output device built in the personal computer body, or There has been a problem that a floppy disk or the like malfunctions due to vibration.

The present invention solves such conventional problems,
It is an object of the present invention to provide a speaker device having excellent performance in which vibration is hard to be transmitted to the outside.

[0008]

In order to solve this problem, a speaker device according to the present invention is formed by extending one end of a reinforcing cauldron connecting two opposite surfaces of a cabinet having a speaker connected to the front surface from the cabinet. The above-mentioned projection-shaped engaging portion is provided.

[0009]

With this configuration, even if the cabinet resonates due to the sound waves emitted from the speaker, the reinforcing joint connecting the two opposite surfaces increases the mechanical strength of the cabinet and suppresses the magnitude of the resonance. Since the vibration of the part where is attached can be minimized, the vibration is most difficult to be transmitted to the engaging portion formed by extending the reinforcing shaft, and the vibration of other cabinets via the engaging portion. Transmission is suppressed.

Therefore, even when used in a personal computer for multimedia, etc., the vibration is difficult to be transmitted, and the malfunction of the personal computer due to the vibration can be prevented, and a speaker device suitable for use in the personal computer etc. can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A speaker device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front sectional view showing the structure of the speaker device according to the embodiment. In FIG. 1, reference numeral 1 denotes a cabinet provided on the back surface of the speaker 4, and the cabinet 4 having the speaker 4 coupled to the front surface thereof, and 3 denote other parts. Cabinet (shown in cross section of the main part), 5 is a reinforcing cauldron connecting the two surfaces of the cabinet 1 facing each other, and 6 is an attachment hook formed by extending one end of the reinforcing cask 5 to form an engaging portion. is there.

The operation of the speaker device of the present invention configured as described above will be described below.

When the sound wave radiated from the speaker 4 to the back causes the cabinet 1 to resonate, and when this vibration is transmitted to the other cabinet 3 through the mounting hook 6, the reinforcing coffin 5 connects the side surfaces of the cabinet 1. Therefore, at the time of resonance, this portion has the least vibration, and since the vibration of the mounting hook that is continuously extended to this reinforcing rod 5 is also very small compared to the other cabinet 1 portion, the cabinet of other electronic equipment etc. The vibration transmitted to 3 is also very small, and the vibration of the cabinet 1 is large with the mounting hook 2 provided on the side surface of the cabinet 1 as in the conventional case, and the transmitted vibration is also large, which is unnecessary vibration transmission. It is possible to realize an excellent speaker device which is most suitable as an external speaker device for a personal computer with a small number of users.

Although the mounting hook 6 is L-shaped in this embodiment, the other cabinet 3
Any shape may be used as long as it matches the shape of the attachment portion of the above, and the vibration transmission can be further reduced by providing not only one reinforcing rod 5 but also a plurality of reinforcing rods 5.

Further, by providing the cabinet 1 with the engaging recess in which the mounting hook 6 is fitted, the speakers can be easily connected to each other.

[0017]

As described above, in the speaker device according to the present invention, the mounting hook is formed by extending one end of the reinforcing cauldron, which is formed by connecting a part of two opposite surfaces of the cabinet provided on the back surface of the speaker, from the outer surface of the cabinet. Due to the formed structure, vibration due to resonance of the cabinet due to sound waves emitted from the speaker is suppressed, and a hook for mounting is provided on the reinforcing shaft that minimizes the vibration, so that the vibration can be transmitted when it is mounted on other electronic devices. It is possible to provide a very excellent speaker device which can be made small and which is optimal as an external speaker device for a personal computer equipped with a data input / output device that causes a malfunction due to vibration of a CD-ROM or the like. It is possible.
