Description
Technical Field
The utility model relates to an electroacoustic product field, concretely relates to waterproof loudspeaker for wrist-watch.
Background
Diving has become a favorite sport for many young people. During diving, the diving is generally submerged to two meters deep, and a diver needs to estimate the diving time and set the time for floating. However, the underwater diver often cannot always look at the watch for paying attention to the time, and meanwhile, the underwater diver cannot clearly see the numbers on the watch, so that the waterproof watch needs to have an alarm function to prompt the underwater diver. The traditional waterproof watch does not generally have a loudspeaker, and if the loudspeaker is arranged in a sealed cavity of the watch, the sound of the loudspeaker is extremely small and difficult to hear because the four sides are sealed. If a speaker is to be installed in a wristwatch, the wristwatch must be perforated to allow the sound of the speaker to be emitted, and therefore the speaker itself must be waterproof.

In view of the above problem, the utility model provides a waterproof loudspeaker for wrist-watch.
In order to solve the technical problem, the utility model discloses a technical scheme as follows: a waterproof speaker for a watch, comprising: the loudspeaker comprises a basin frame with two through sides, wherein a front cover and a magnetic cover are fixedly adhered to the two axial sides of the basin frame through waterproof glue, a voice coil and a waterproof sound membrane are sequentially arranged in a cavity formed by the basin frame and the front cover along the direction from the basin frame to the front cover, and silk yarns are arranged around the voice coil; in a cavity formed by the basin frame and the magnetic cover, a pole piece and a magnetic pole are sequentially arranged along the direction from the basin frame to the magnetic cover.
In the waterproof horn for the watch, the front cover and the magnetic cover are closed on two sides of the basin frame to form a box body, and waterproof glue is adopted for bonding, so that the waterproof effect is achieved; while the waterproof sound membrane further prevents water from entering from the front cover.
As an improvement of the utility model, the front cover is provided with a waterproof rubber cushion at one side far away from the basin frame. The waterproof rubber mat is arranged, so that the loudspeaker can prevent water from flowing into the loudspeaker from the periphery of the loudspeaker at the position where the loudspeaker is adhered to the watch, and the waterproof capacity of the loudspeaker is improved.
As another improvement of the utility model, the magnetic pole includes main magnetic pole and auxiliary magnetic pole, the main magnetic pole passes through waterproof glue and the bonding of auxiliary magnetic pole. The utility model discloses a design of major-minor double-magnetic pole makes magnetic field stronger, can effectual increase voice coil loudspeaker voice coil amplitude to improve loudspeaker sound production volume.
As another improvement of the present invention, the waterproof sound membrane is connected and sealed with the front cover by a hot melting means. Compared with other connection modes, the connection mode of the hot-melt waterproof sound membrane can play a better waterproof role, and the sealing effect is better.
Furthermore, the waterproof sound membrane is of a three-layer structure, the middle layer is a damping layer, and waterproof layers are wrapped on two sides of the damping layer. The damping layer plays the effect of optimizing tone quality.
Furthermore, the waterproof sound membrane is made of polyether-ether-ketone. The polyether-ether-ketone is a special engineering plastic with excellent performances of high temperature resistance, self-lubrication, easy processing, high mechanical strength and the like, and has high durability and difficult damage.
Therefore, compared with the prior art, the waterproof horn for the watch mainly has the following advantages:
1) the utility model discloses simple structure, waterproof performance is good, can realize waterproof function two meters within ranges under water.
2) The utility model discloses a broadcast volume is big, and tone quality is better, is easily noticed by the user.
