FR2766649A3 - Loudspeaker assembly e.g. for motor vehicle - Google Patents

Abstract

The assembly has an annular basic frame around which four attachment holes (11) for the loudspeaker body (2) are uniformly distributed. The body has four radial protrusions (21) with corresponding holes (211), and a central socket (22) which accepts the ball (311) at the end of the stem (31) of the tweeter (3). When the tweeter is pushed into the socket it can be rotated so as to face in any desired direction and, once adjusted, to maintain that direction in relation to the body of the assembly by friction while remaining open to readjustment for a different direction when necessary.

Description

Speaker with adjustable tweeter
The present invention relates to loudspeakers and relates more particularly to a loudspeaker which comprises a tweeter, commonly called a tweeter, the angular position of which can be easily adjusted.

 In a normal speaker fitted with a tweeter, the latter is fixedly mounted in the center of the body of the speaker and is supported by an annular base structure. Because the tweeter is fixedly attached to the body of the speaker, it is not possible to adjust its angular position. Since the high frequency sound wave emitted by the tweeter is transmitted in a linear direction, the user cannot correctly perceive the sound of the tweeter if it is not pointed at him.

 The present invention has been designed taking into account the drawback mentioned above. The main object of the present invention is to provide a loudspeaker comprising an annular base structure, a loudspeaker body mounted on said annular base structure, and a tweeter mounted on said loudspeaker body at the center thereof, characterized in that the body of the loudspeaker comprises a ball socket at its center, said tweeter comprising a lower rod ending in a spherical connector, said spherical connector being force fitted into said socket ball and rotatable therein so that one can move said tweeter to change its angular position relative to said speaker body.

The present invention will now be described with reference to the accompanying drawings, in which:
Figure 1 shows a loudspeaker according to the present invention;
Figure 2 is an exploded view of the loudspeaker according to the present invention;
Figure 3 is an overall view, partially in section, of the loudspeaker of the present invention;
Figure 4 is a view similar to Figure 3 but showing the tweeter in adjustment positions; and
FIG. 5 is a view showing the loudspeaker installed in a motor vehicle, the angular position of the tweeter having been adjusted.

 Referring to FIGS. 1 to 3, it can be seen that a loudspeaker according to the present invention comprises an annular base structure 1 comprising a plurality of equidistant mounting holes 11, a loudspeaker body 2 mounted on the structure of annular base l, and a tweeter 3 mounted on the body 2 of the loudspeaker, in the center thereof. The body 2 of the loudspeaker comprises a plurality of equidistant ears 21 provided with respective mounting holes 211 respectively coupled to the mounting holes 11 of the annular base structure, and a ball socket 22 located in the center. The tweeter 3 comprises a rod 31 extending downwards from the center of its lower side and ending in a spherical connector 11. The spherical connector 11 is forcibly fitted into the ball socket 22.

 Referring to Figure 4, we see that when the spherical connector 11 is coupled to the ball socket 22, it can be rotated with the rod 31 in the ball socket 22 to change the angular position of the tweeter 3 relative to the ball socket 22.

 With reference to FIG. 5, and to FIG. 4 again, it can be seen that when the loudspeaker is installed in a motor vehicle, the tweeter can be oriented in the desired direction. Because the spherical connector 311 fits into the ball socket 22, the tweeter 3 is held firmly in position after each adjustment.

 It is understood that the above description has been given for illustrative purposes only and that variants and modifications may be made thereto within the framework of the present invention.

Claims (1)

 1. A loudspeaker comprising an annular base structure (1), a speaker body (2) mounted on said annular base structure, and a tweeter (3) mounted on said speaker body in the center thereof, characterized in that the body of the loudspeaker comprises a ball socket (22) at its center, said tweeter comprising a lower rod (31) terminating in a spherical connector (311), said spherical connector being forcibly fitted into said ball socket and able to rotate therein so that said tweeter can be moved in order to modify its angular position relative to said loudspeaker body.
