Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a composite speaker system in which a combination of speaker units constituting a composite speaker can be easily and easily replaced or added.

[Conventional technology and its problems]

As speaker systems, particularly in-car audio devices, composite speaker systems such as single-cone type to two-way and three-way type have been widely adopted with the intention of expanding acoustic effects in the vehicle.

In order to achieve such an object, many conventional composite speaker systems have a low-pitched speaker 2 and a high-pitched speaker 3 arranged in parallel on the plane of one baffle plate 1 as shown in FIG. A way type speaker system is configured.

However, when it is desired to change the two-way speaker system according to the above method to a three-way method speaker system incorporating the mid-range speaker 5, a new baffle plate is required as shown in FIG. Since the speaker box 4 having a size suitable for the board is required, the combined speaker system installed in a limited place such as a car cannot avoid increasing the size of the entire device.
It is not preferable as an in-vehicle composite speaker system that requires miniaturization, and there are disadvantages such as cost increase.

In order to eliminate these disadvantages, for example, as disclosed in Japanese Utility Model Laid-Open No. 53-81031, a first speaker (slave speaker) is attached to the inner surface of a cabinet having a sound output hole, and the first speaker is attached. A speaker mounting device has been proposed in which a larger second speaker (main speaker) is mounted on the inner surface of the cabinet so as to cover the first speaker.

The speaker mounting device is extremely effective in that a plurality of speakers having different sound ranges can be acoustically and space-efficiently mounted.

However, since the composite speaker system obtained by the speaker mounting device disclosed in the above publication is completely fixed to any speaker cabinet, the structure of the composite speaker system can be easily changed by using the same baffle plate. Alternatively, it is impossible to add more, and a new cabinet is required for the change or addition, and there are problems to be solved in practice, such as having to prepare many kinds of parts in advance. .

In view of the present situation of the present invention, it is an object of the present invention to provide a composite speaker system in which the speaker units constituting the composite speaker can be easily and easily replaced or added.

[Means for Solving the Problems]

In order to achieve the above object, a composite speaker system of the present invention is a composite speaker system in which a sub speaker is provided inside a baffle plate having a sound output hole, and a main speaker having a large diameter is provided to cover the sub speaker. A first ring body having a ring-shaped engagement groove formed concentrically with the sound output hole inside the baffle plate, and an engagement piece engaging with the engagement groove provided on the front surface; A second ring body having an engaging groove for mounting a follower speaker and having a smaller diameter than the first ring body is integrally connected by a plurality of arms to form a leg body, While fixing the slave speaker to the second ring body, the engagement piece formed on the first ring body is engaged with the engagement groove formed inside the baffle plate to lock the slave speaker to the baffle plate, The sub-speaker locked to the baffle plate When fixing the main speaker to the baffle plate, the conventional speaker is detachably attached to the baffle plate by pressing the first ring body of the leg to which the slave speaker is fixed at the outer peripheral edge of the main speaker to the baffle plate. It is characterized in that it is configured to.

The baffle plate used in this invention is not limited in size or material, but if two sound emitting holes are formed in a plane, for example, low-pitched, mid-pitched, treble, and super-treble speaker units can be used. It is possible to construct a 4-way composite speaker system.

[Action]
