Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker mounting bracket, and more particularly to a speaker mounting bracket that can be easily attached and detached without damaging the speaker itself.

[0002]

2. Description of the Related Art Conventionally, in audio equipment, various developments have been made to improve sound quality. One of the things desired for such audio equipment is the acoustic characteristics of the speaker.

For example, in the field of home audio, an enclosure which is usually provided together with a baffle plate has been improved in order to improve the acoustic characteristics of the speaker. The enclosure encloses the sound radiated from the rear surface of the speaker, and can prevent deterioration of acoustic characteristics due to sound interference on the front and rear surfaces of the speaker.

On the other hand, in the field of car audio,
From the viewpoint of size and weight reduction of the automobile itself, it is relatively difficult to obtain similar acoustic characteristics using the enclosure. Instead, in a rear speaker used for a car audio system, it is known that the rear side of the speaker is penetrated into the trunk room to provide the trunk room itself with an enclosure function. However, since the space volume in the luggage compartment varies depending on the amount of luggage stored in the luggage compartment, the rear speaker cannot always obtain the same acoustic characteristics.

In addition, in speakers used for car audio, durability which home audio does not have is also desired. For example, in summer, the temperature in the passenger compartment may rise to around 90 ° C. due to hot weather, but in winter, it may drop to below zero. Further, in the speaker attached to the door trim, the shoes of a passenger wet due to rainfall may touch the speaker. In order to avoid malfunction of the speaker and / or deterioration of sound quality due to these, the car audio speaker needs to have excellent durability such as heat resistance, moisture resistance, and water repellency.

Furthermore, in recent years, the weight of the automobile itself has been further reduced; the accessories have been downsized in order to secure a wider interior space; and the front, center, and to reduce the difference in acoustic characteristics caused by the seating position of the passenger. It is also important to individually set the sound pressure characteristics of each channel of the speaker placed in the rear.

From this point of view, in the field of car audio, a speaker completely different from the home audio has been independently developed. As a result, a car audio speaker that satisfies these requirements has high durability, but is relatively expensive.

Speakers for car audio are used for specific interior parts such as automobile door trims, instrumental panels, rear trays, tweeters, etc. according to acoustic characteristics.
There are a total of 2 to 10 speakers such as woofers. The speakers provided in these places are usually fixed with screws or adhesives. However, if such fixing is performed, there is a problem that it takes time to attach and detach in repairing or replacing an interior part due to an accident, workability is deteriorated, or the speaker itself may be damaged. Further, even if the recycling of each part after the scrapped vehicle is taken into consideration, it takes a lot of time to remove it, which is not sufficiently satisfactory.

[0009]

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and an object of the present invention is to mount a speaker used for a specific purpose such as a car audio, and then to provide a sound quality of the speaker. It is an object of the present invention to provide a speaker mounting bracket that can be easily attached and detached without deteriorating the characteristics and can reduce the possibility of damage to the speaker due to the attachment and detachment.
