Description

Integrated handheld horn

Technical Field

The utility model belongs to the technical field of the system of specificities propaganda directed to, concretely relates to horn is handed with integral type to public address.

Background

The handheld horn seen in the market at present is structurally assembled and assembled by single parts and comprises a horn rear cover, a horn front cover, a horn mouth and a horn handle, and the structure is continuously for many years without any improvement and innovation in the structure technology.

For example, the horn back cover and the key part are separately installed, one key part is matched with one back cover, and the matched installation of the horn back cover and the key part is undoubtedly added with an installation step for production, and undoubtedly adds production cost for enterprises.

For example, the horn handle is made into a folding type, is connected with the horn front cover in a perforation mode, mostly, grooves with certain angles are designed on the horn front cover and the horn rear cover, corresponding arc bosses are designed on corresponding positions on the handle, the matching of the bosses and the grooves of joint positions of the front cover and the rear cover are utilized to fix and lock the angle to prevent swinging, and the toughness of plastic is utilized to break away the constraint of the grooves and rotate. The structure mode is that the plastic toughness is utilized to forcibly rotate, and the matching part of the upper cover and the lower cover of the handle is easily opened when rotating. The friction force between the matching of the parts is large, the loss is large, the stress point at the bottom of the boss is fatigue and soft, and the function of preventing swing is gradually unavailable after the times are increased. The structure increases the cost on the die, increases the processing difficulty of the die, increases the maintenance difficulty of the die, reduces the process level of the product, leaves traces of the joint of the die slide block on the surface of the product and has great influence on the appearance of the product.

For example, the horn front cover and the high pitch cover are installed in a split mode, the high pitch diaphragm and the magnet are installed in a combined mode and then installed on the horn front cover and the horn mouth, the installation is too complex, the production efficiency is not improved, and the cost of increasing production through one more set of dies is needed. In addition, the T iron, the Huatz and the magnet of the high-pitch cover are bonded firstly and then the assembly body and the high-pitch diaphragm are bonded and installed on the high-pitch cover, the T iron, the Huatz and the magnet are assembled by the method, very accurate positioning is required, unbalance of magnetic gaps is caused once deviation exists, high-pitch damage is caused, defective products are easily generated, and production efficiency is difficult to improve relatively.

For example, the horn mouth, the treble reflection tube and the treble cover are assembled in a split mounting mode, the mounting steps are complex due to the mounting in the mode, the gap of the joint between the three parts and the overall shape can further have adverse effects on the sound effect output of the whole horn, and the output volume sound effect is reduced.
