Description

[Detailed description of the invention] [Field of industrial application] This invention is applied to a power supply line for a composite speaker, in particular a composite speaker in which a treble speaker is arranged by an arm member bridged over the opening of the bass speaker. Regarding structural improvements.

[Prior Art] A conventional composite speaker of this type will be explained with reference to FIG. 3. In the figure, 01 is a bass speaker, 015 is a speaker frame, and 03 is an arm member bridged to the frame 015. The recess 0 formed in the center of the arm member 03
A treble speaker 02 (in the figure, a piezoelectric element 021, a cone-shaped diaphragm 022, a lead wire 023, and a terminal fitting 024
A piezoelectric speaker) is installed.

Then, the mounting piece 01 formed on the frame 015
A terminal board 011 is fixed to 6, and the terminal board 011
The tinsel wire 014 connected to the voice coil lead wire 0 passes through the diaphragm 012 and connects to the voice coil lead wire 0 on the surface of the diaphragm 012.
13, and the other end is connected to the terminal fitting 024 of the treble speaker 02.

[Problems to be solved by the invention] In the composite speaker having the above structure, after placing the arm 03 in which the treble speaker 02 is installed in the recess 031 in the opening of the bass speaker 01, Voice coil lead wire 0
The other end of the tinsel wire 014 connected to the treble speaker terminal fitting 024 must be connected to the treble speaker terminal fitting 024.

Therefore, it is necessary to insert the soldering iron into the opening of the frame 03 to perform the work, which is extremely cumbersome, and the tip of the soldering iron is not connected to the diaphragm 01.
Since the diaphragm 012 is likely to come into contact with the diaphragm 012, accidents such as partial burnout of the diaphragm 012 are likely to occur.

In addition, in a thin speaker, the tinsel wire 0 of the diaphragm 012
14 penetration part and the high-pitched speaker terminal fitting 024, it is not possible to obtain an appropriate interval in the vibration direction of the diaphragm 012, and it is not possible to give sufficient slack to the tinsel wire 014, so the amplitude of the diaphragm 012 is There have been difficulties in providing a composite speaker having a large bass speaker.

[Means for Solving the Problem] This invention provides a composite speaker having a bass speaker and a treble speaker disposed on an arm member bridged to an opening of the bass speaker, in which A lead wire of a treble speaker is attached to the terminal fittings arranged, and a tinsel wire whose one end is connected to the terminal plate of the bass speaker and whose part passing through the diaphragm is connected to the voice coil lead wire of the bass speaker. This is a composite speaker with each end connected.

[Example] In FIG. 1, 1 is a bass speaker, 15 is a speaker frame, 3 is an opening edge of the frame 15, and the outermost part of the diaphragm 12 is pressed,
An annular portion 33 coupled to the frame 15 and an arm portion 32 bridging the annular portion 33 in the radial direction.
It is an arm member consisting of a treble speaker 2 (in the figure, a piezoelectric element 2
1. A piezoelectric speaker consisting of a cone-shaped diaphragm 22 and a lead wire 23 is provided.

Further, a terminal fitting 4 is fixed to the arm portion 32 so as to protrude into an opening formed between the arm portion 32 and the annular portion 33, and a lead wire of a treble speaker is connected to the terminal fitting 4. 23 are connected.

Then, the terminal plate 11 is fixed to a mounting piece 16 formed on the frame 15, and the tinsel wire 14 connected to the terminal plate 11 passes through the diaphragm 12.
Connected to the voice coil lead wire 13 on two sides,
Furthermore, the other end is connected to a portion of the terminal fitting 4 that protrudes into the opening.

[Effects of the invention] According to the speaker of this invention in the above embodiment, the treble speaker 2 is installed in the recess 31 in advance, and the arm member 3 to which the lead wire 23 of the treble speaker is connected to the terminal metal fitting 4 is used for bass sound. After placing it in the opening of the speaker 1, the other end of the tinsel wire 14 connected to the voice coil lead wire 13 on the surface of the diaphragm 12 is connected to the protruding part of the terminal fitting 4 attached to the arm part 32. However, since the terminal fitting 4 is arranged in the opening of the bass speaker 1, the soldering work is extremely easy, and the diaphragm 12 is not partially burnt out by the tip of the soldering iron.

Furthermore, since the terminal fitting 4 is arranged on the arm member 3, a sufficient distance can be obtained between the diaphragm penetrating portion of the tinsel wire 14 and the terminal fitting 4 in the vibration direction of the diaphragm 12.
It is possible to provide a composite speaker having a bass speaker 1 in which sufficient slack can be given to the tinsel wire 14 and the vibration amplitude of the diaphragm 12 is large.
