Description

A multi-directional imitation rock speaker

The utility model relates to a sound box, in particular to a waterproof sound box which can be placed in open places such as parks.

Existing speaker cabinets are generally composed of multiple wooden boards that are enclosed and connected. They are generally placed indoors and are not suitable for placing in open places such as parks. Moreover, this speaker cabinet has low mechanical strength, poor thermal stability, High water absorption, non-wearing and corrosion-resistant, poor sound-absorbing performance, low fidelity and other disadvantages require the use of harder and thicker wood to make, wasting wood resources. In response to the above situation, there are now speaker bodies made of ceramics, stone or other inorganic materials on the market, which overcome some of the problems of wooden speakers, but because most of them are made of several plates through some special methods such as waterproof resin Due to the poor sealing performance of the joints, the waterproof effect is relatively poor, the thermal stability is not high, and the sound absorption performance is not good, especially when natural stone or artificial agate is used. It is bulky and inconvenient to assemble and disassemble. When it is made of ceramics, its mechanical strength is not high, it is easy to break, and it is not wear-resistant, which brings inconvenience to use.

The purpose of the utility model is to provide an open-air waterproof rock-like speaker with high mechanical strength, good integrity, superior sound-absorbing performance, high fidelity, good waterproof effect, and can transmit sound in multiple directions.

The utility model includes a box body and a horn installed in the box body, and is characterized in that the box body is composed of an integrally formed hollow seat body and a bottom plate, wherein the shape of the seat body is an irregular stone-like body with unevenness, and the horn mouth It is installed on the middle and lower part of the base body facing upwards, and several sound guide holes are opened on at least two sides of the base body, and the bottom plate is sealed and fixed on the bottom opening of the base body.

In order to further ensure that the sound can be transmitted to the surroundings reliably and efficiently, the top of the inner cavity of the seat is provided with a conical reflector with the conical top facing down that can reflect and conduct sound.

In order to further enhance the waterproof effect of the utility model, so that it can be reliably placed in open-air places such as parks, and is not afraid of wind and rain, the inner walls of the sound guide holes of the above-mentioned base body are provided with waterproof net covers. The parts corresponding to the sound guide holes on each side of the seat body are inwardly indented to form an inner concave part.

Because the utility model adopts the stone-like seat structure in which the bell mouth is upwardly arranged in the seat body and sound guide holes are provided on multiple sides of the seat body, the horn can be conveniently installed in the box and easy to disassemble and maintain, and it also makes it It can effectively overcome the shortcomings of wooden speakers. It has the advantages of high mechanical strength, good rigidity, good thermal stability, low water absorption, wear resistance and corrosion resistance, superior sound absorption performance, and high fidelity. The sound can be reliably transmitted in the direction, and can effectively prevent rainwater from entering the speaker in the box, and it also has the advantages of long service life, no fear of humidity, and aging resistance, and it also has beautiful appearance and can realistically simulate various kinds of stones. The shape enables the utility model to be reliably placed in open-air places such as squares, parks or family balconies, adding a sound scene to squares and parks, and more realistically simulating a wild environment.

Basic structure and working principle of the present utility model are described in detail below in conjunction with accompanying drawing:

Fig. 2 is the sectional structure schematic diagram of the utility model;

As shown in Figures 1-2, the utility model includes a box body 1 and a horn 2 installed in the box body 1, and is characterized in that the box body 1 is composed of an integrally formed hollow seat body 11 and a bottom plate 12, wherein the seat body The body 11 and the bottom plate 12 are structures formed by molding and sintering at high temperature using inorganic materials. Simultaneously, the shape of the seat body 11 is an irregular stone-like body with unevenness, and the horn 2 is installed on the middle and lower part of the seat body 11 facing upwards, and at least two sides of the seat body 11 are provided with some sound guide holes 3, and the bottom plate 12 It is sealed and fixed on the bottom opening of the seat body 11 . In order to facilitate the installation of the horn 2, an inwardly protruding annular boss 13 on which the horn 2 can be installed and fixed is provided at the middle and lower part of the inner wall of the seat body 11 . The annular boss 13 is pre-embedded with a plurality of screw rods that can pass through the mounting holes of the horn 2, and the horn 2 is fixed in the inner cavity of the seat body 11 through the locking installation and installation of the screw rods and nuts passing through the mounting holes. In order to ensure the effect of reliably transmitting sound to the surroundings, sound guide holes 3 are provided on the four sides of the base body 11 . At the same time, the top of the inner cavity of the seat body 11 is provided with an inclined-plane reflection cover composed of at least two inclined surfaces facing the sound guide hole, which can reflect and conduct sound. In this embodiment, in order to meet the needs of the sound guide holes on its four sides, the top of the inner cavity of the seat body 11 is provided with a conical reflector 5 with the conical top facing down that can reflect and conduct sound. In order to further enhance its waterproof effect, so that it can be reliably placed in open-air places such as parks, and is not afraid of wind and rain, the inner walls of the sound guide holes 3 of the above-mentioned base body 11 are provided with waterproof net covers.
