This type of horn consumes too much power and has a low efficiency. In the era of new energy electric vehicles, it is no longer applicable. It is necessary to reduce the power consumption of the horn, so now electronic horns based on the speaker principle must occupy the market. Summary of the invention:

[0006] The purpose of the present invention is to provide a magnetoelectric speaker type electronic speaker and a manufacturing method, which utilizes the efficient speaker principle to manufacture the magnetoelectric speaker, so that the sound power consumption of the speaker is reduced from 50W to about 10W, and the power consumption is reduced by 80%.

[0007] The above purpose is achieved through the following technical solutions:

[0009] The magnetoelectric speaker type electronic speaker, the outer ring of the pressure cover is fitted with the upper end of the shell, a PCB board is installed on the left bottom surface of the shell, the PCB board is connected to the wiring terminal, and the magnetic column at the bottom of the magnet passes through the bottom plate of the shell.

[0010] The magnetoelectric speaker type electronic horn, the material of the conical paper cone is a metal sheet or a diaphragm of a non-metallic material, and its shape is the shape of a motor vehicle horn.

[0011] The magnetoelectric speaker type electronic speaker, the PCB board includes a power supply circuit, the power supply circuit is respectively connected to the baseband circuit, the control circuit, and the power module, a driving module is installed between the control circuit and the power module, the baseband circuit is connected to the closed-loop feedback circuit, and the closed-loop feedback circuit is connected to the speaker.

[0012] A magnetoelectric speaker type electronic speaker and a manufacturing method, the method comprising the following steps: first, according to the speaker manufacturing principle, an elastic steel diaphragm is no longer needed, a conical paper cone is manufactured by a thin metal pressing method or a non-metallic material shaping method, a special mold is used for manufacturing, the conical paper cone is processed into a shape that can match the existing motor vehicle horn, and the sound channel for sound enhancement or sound amplification imitates the shape of the existing motor vehicle horn; the shape of the conical paper cone is a diaphragm with a metal sheet or a non-metallic material, the diaphragm does not need to have a self-rebound function, and the diaphragm only needs to have the function of driving air vibration, and the vibration power of the diaphragm is driven by the speaker voice coil.

[0013] Beneficial effects:

[0014] 1. The present invention discloses a magnetoelectric speaker type electronic speaker. The structure uses the efficient speaker principle to make a magnetoelectric speaker, so that the sound power consumption of the speaker is reduced from 50W to about 10W, and the power consumption is reduced by 80%.

[0015] 2. The material of the conical paper cone of the present invention is a metal sheet or a non-metallic diaphragm, and its shape is the shape of a motor vehicle horn. The advantage of this structure is that the power of vibration sound generation is greatly reduced, and a variety of sounds of different sizes can be generated at the same time. Several different horns or sound-generating devices in the electric vehicle can be integrated into one, for example, it can be used as a whistle horn, as a pedestrian reminder, and as a warning alarm sound. In addition, it should be able to complete the broadcast shouting function, etc., which can greatly reduce the production cost of the sound-generating device in the electric vehicle body.

[0016] 3. The present invention is based on the principle of the speaker itself and no longer requires an elastic steel diaphragm. The paper cone of the speaker is made into a shape that can match the existing motor vehicle horn by a thin metal pressing method or a non-metallic material shaping method. The sound channel for sound enhancement or sound amplification imitates the shape of the existing motor vehicle horn, which can ensure that the appearance of the existing motor vehicle horn remains unchanged, and the installation position and installation form are the same.

[0017] 4. The diaphragm of the speaker-type electronic speaker of the present invention is a metal sheet or a non-metallic material diaphragm that is slightly shaped like a speaker cone. This diaphragm no longer needs to have a self-rebound function, but only needs to have the function of driving air vibration, and its vibration power is driven by the speaker voice coil.
