Problems solved by technology

Since the electrodes of the speaker are divided into positive and negative poles, the positive and negative poles of the electrodes need to be connected to the corresponding positive and negative poles of the power supply. The traditional detection method is easy to connect the positive and negative poles wrongly, which will lead to the damage of the speaker. Operational safety low, and the detection efficiency is low

Abstract

The invention discloses a pure-tone pole-measuring mistake-proofing clamp for a loudspeaker. The pure-tone pole-measuring mistake-proofing clamp comprises a base, a positioning groove is formed in thebase; two symmetrically arranged clamping grooves are formed in the base on one side of the positioning groove; a positive label is arranged on one side of one clamping groove; a negative label is arranged on one side of the other clamping groove; conductive sheets are embedded in the bottoms of the two clamping grooves; the conducting strip corresponding to the positive pole label is electrically connected with the positive pole wire; A clamping groove is formed in the base, a conducting strip corresponding to the negative label is electrically connected with the negative wire, a gland is installed above the base corresponding to the clamping groove through a guide rail structure in a sliding mode, two pressing wheels inserted into the clamping groove are arranged at the bottom of the gland, and the pressing wheels are installed at the bottom of the gland through bearings in a rotating mode. The pure-tone pole-measuring mistake-proofing clamp for the loudspeaker is compact in structure and convenient to use, the positive pole and the negative pole of the loudspeaker can be in correct butt joint with the positive pole and the negative pole of a power supply quickly, the detectionefficiency is improved, and the operation safety is ensured.

Description

technical field [0001] The invention relates to the technical field of loudspeaker detection, more specifically, it relates to a pure tone measuring pole error-proof fixture of a loudspeaker. Background technique [0002] After the speaker is produced, it usually needs to be tested for its pure tone to judge whether the product is qualified. The traditional detection method is to manually bind and connect the electrodes of the speaker to the wires, and then use a pure tone fixture to detect whether there is any noise after the power is turned on. Since the electrodes of the speaker are divided into positive and negative poles, the positive and negative poles of the electrodes need to be connected to the corresponding positive and negative poles of the power supply. The traditional detection method is easy to connect the positive and negative poles wrongly, which will lead to the damage of the speaker. Operation safety low and low detection efficiency.
