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 is used to wrap sound emitted from the rear of the speaker and prevent deterioration of acoustic characteristics due to interference of sound in the front and rear of the speaker.

On the other hand, in the field of car audio,
From the viewpoint of size and weight reduction of the vehicle itself, it is relatively difficult to obtain acoustic characteristics equivalent to those of home audio by using an enclosure. Instead of this, a rear speaker used for a car audio is configured so that the rear surface of the rear speaker is penetrated into the trunk room to serve as an enclosure in the trunk room itself. 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 a certain acoustic characteristic.

Further, in a speaker used for car audio, higher durability than that required for home audio is also desired. For example, in summer, the temperature inside the vehicle may rise to around 90 ° C. in 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 who has been wet due to rainfall may touch the speaker. In order to avoid speaker malfunction and / or sound quality deterioration due to these factors, car audio speakers must be heat resistant, moisture resistant, and
It is necessary to have excellent durability such as water repellency.

Further, in recent years, the weight of the automobile itself has been further reduced, and the accessories for securing a wider room have been miniaturized, and accordingly, the performance of the speaker is also required to be improved. For example, it is also important to individually set the sound pressure characteristic of each channel of the speakers arranged in the front, center, and rear in order to slow down the difference in acoustic characteristics caused by the seating position of the passenger.

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 excellent 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, when such fixing is performed, in repairing or replacing an interior part due to an accident, there is a problem in that attachment and detachment takes time, workability is poor, 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]
