Embodiment 2
[0055] In the second embodiment, a voice coil manufacturing method is also provided, which utilizes the coil heating device in any of the above embodiments, including the following steps:
[0056] Inserting the first coil 10 into the heating column 110, and then inserting the second coil 20 into the preset position of the heating column 110;
[0057] Pass the heating gas into the heating column 110 through the flow channel 120;
[0058] reaching the preset time or preset temperature, so that the first coil 10 and the second coil 20 are in close contact;
[0059] The first coil 10 and the second coil 20 are bonded and fixed to form a voice coil.
[0060] When the voice coil manufacturing method above is used, the hot air directly acts on the heating column 110 through the flow channel 120, and the heat energy can be fully utilized to heat the heating column 110, reducing heat loss and improving heat utilization; 110 in the flow channel 120, so that the heating column 110 can ...
Embodiment 3
[0064] In the third embodiment, a voice coil is also provided, which is obtained by using the voice coil manufacturing method in any of the above embodiments. The voice coil adopts the above method for manufacturing the voice coil, which can reduce energy loss in the manufacturing process and is beneficial to reduce the manufacturing cost.
Embodiment 4
[0065] In Embodiment 4, a loudspeaker is also provided, which adopts the above-mentioned voice coil. The loudspeaker adopts the above-mentioned voice coil, which can reduce the production cost and help to improve the market competitiveness.
[0066] It should be noted that the coil is obtained by winding a metal wire coated with glue, so the bonding between the coils can be fixed without applying glue, and can be fixed into a voice coil by direct heating.

Abstract
The invention discloses a loudspeaker, a voice coil, a voice coil manufacturing method and a coil heating device. The coil heating device comprises a heating piece and a supporting base, the heating piece comprises a heating column used for being connected with a coil in an inserted mode, the heating column is provided with a flow channel and a plurality of first air outlet holes formed in the outer side of the heating column at intervals, and the first air outlet holes communicate with the flow channel; the supporting base is provided with a supporting body, and the supporting body is arranged below the first air outlet holes and used for forming a supporting part for supporting the coil. The coil heating device can reduce heat loss and improve the heat utilization rate. The voice coil manufacturing method utilizes the coil heating device, and is beneficial to reducing the manufacturing cost of the voice coil. The voice coil adopts the voice coil manufacturing method, so that the energy loss in the manufacturing process can be reduced, and the manufacturing cost can be reduced. The loudspeaker adopts the voice coil, so that the production cost can be reduced, and the improvement of the market competitiveness is facilitated.
Description
technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker, a voice coil, a voice coil manufacturing method and a coil heating device. Background technique [0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. The voice coil is forced to move in a magnetic field when it is energized, thereby driving the diaphragm to vibrate and producing sound. [0003] At present, when making a voice coil with at least two coils, each coil is individually wound, and then each coil is bonded and fixed at one time. During the bonding and fixing process of all the coils, the external hot air is used to bake and heat all the coils, and at the same time, at least two rotating shafts are used to drive the coils to rotate, so that all the coils are heated evenly. And this kind of processing method generally has low heat utilization rate. Contents of the invention [0004] Based on this, it ...
