With the increase of the screen occupation ratio of the mobile phone, the distance between the sound outlet hole and the top frame of the mobile phone is reduced to L2.

and the first diaphragm is connected with the first sub-conversion module and used for vibrating according to the first acting force and generating a first sound wave signal.

Here, the first electromagnet unit may include at least one electromagnet.

The first diaphragm vibrates under the action of a first action force to generate a first sound wave signal.
Illustratively, the frequency range of the first acoustic signal includes: 400 hz to 4 khz.
In some embodiments, the size of the first diaphragm is greater than a size threshold. It will be appreciated that when the first diaphragm vibrates, the volume of air pushed by the first diaphragm is greater than the volume threshold, so that the first diaphragm has a higher sensitivity to audio sub-signals having a frequency less than or equal to the frequency threshold. Here, the frequency threshold may be 4 kilohertz (kHz). I.e. the sensitivity of the moving coil unit is high for audio sub-signals having a frequency below the frequency threshold.
Fig. 4 is a graph illustrating frequency sensitivity of a first conversion module, according to an example embodiment. Referring to fig. 4, the sensitivity of the first conversion module to the first type of audio sub-signal having a frequency in the range of 400 hertz (Hz) to 4kHz is above a first sensitivity threshold. Here, the first sensitivity threshold may be 90 DB.
In this embodiment, the first conversion module processes the first type of audio sub-signals with frequencies less than or equal to the frequency threshold, so that the sensitivity of the electronic device to the first type of audio sub-signals can be increased, and the quality of the generated first sound wave signal can be improved.
In some embodiments, the second conversion module 140 includes:
the second sub-conversion module is used for driving the magnet of the second sub-conversion module to vibrate according to the audio signal to generate a second acting force;
and the second diaphragm is connected with the second sub-conversion module and is used for vibrating according to a second acting force and generating a second sound wave signal.
For example, the second conversion module 140 may include: and a moving iron unit. At this time, the second sub-conversion module may include: a second electromagnet unit; the magnet of the second electromagnet unit is connected with the second vibrating diaphragm, the magnet of the second electromagnet unit can vibrate according to the driving signal, and the coil of the second electromagnet unit is fixed.
When the second sub-conversion module is in a power-on state, the magnet of the second electromagnet unit vibrates in a magnetic field and generates a second acting force according to a Faraday electromagnetic induction principle.

Referring to fig. 5, the sensitivity of the second conversion module to the second type of audio sub-signals with frequencies in the range of 4kHz to 15kHz is above the second sensitivity threshold. Here, the second sensitivity threshold is 110 DB.
When the first conversion module is a moving coil unit and the first conversion module is a moving iron unit, the size of the second vibrating diaphragm is smaller than that of the first vibrating diaphragm, and the size of the second sub-conversion module is smaller than that of the first sub-conversion module. Moreover, since the rigidity of the second conversion module 140 is greater than that of the first conversion module 130, the response sensitivity of the second conversion module 140 to the first type of audio sub-signal is less than that of the first conversion module 130 to the first type of audio sub-signal, and the response sensitivity of the second conversion module 140 to the second type of audio sub-signal is greater than that of the first conversion module 130 to the second type of audio sub-signal.

As shown in fig. 6, when the electronic device includes the first conversion module 130 and the second conversion module 140, the frequency sensitivity curve of the electronic device 100 can be regarded as a superposition of the frequency sensitivity response curve of the first conversion module 130 and the frequency sensitivity curve of the second conversion module 140.
Compared with the case that a single moving coil unit or a single moving iron unit is arranged in the electronic device and used as a conversion module to generate sound wave signals, the moving coil unit is selected as the first conversion unit and the moving iron unit is selected as the second conversion module in the embodiment, and the first sound wave signal generated by the moving coil unit and the second sound wave signal generated by the moving iron unit are superposed and then output, so that the frequency sensitivity defect of the conversion module of a single type can be overcome, and the sound quality output by the electronic device can be improved.
In some embodiments, the distance between the first conversion module 130 and the second conversion module 140 is less than a distance threshold.
Referring to fig. 3a, the first transforming module 130 and the second transforming module 140 may be disposed in parallel. When the first end of the first channel and the first end of the second channel are connected to the same sound outlet, and the distance between the first conversion module and the second conversion module is smaller than the distance threshold, the lengths of the first channel and the second channel are favorably shortened, the loss of the first channel to the first sound wave signal and the loss of the second channel to the second sound wave signal are reduced, and the sound quality output by the electronic equipment is improved.
In some embodiments, the second diaphragm has a modulus of elasticity greater than the modulus of elasticity of the first diaphragm.
It is understood that, since the elastic modulus of the second diaphragm is greater than that of the first diaphragm, when the frequency of the audio signal is greater than the frequency threshold, the sensitivity of the second diaphragm to the audio signal is higher than that of the first diaphragm.
In this embodiment, by processing the audio signal through the second sub-conversion module, the sensitivity of the electronic device to the audio sub-signal with the frequency greater than the frequency threshold can be increased, and the quality of the generated second acoustic signal can be improved. In addition, the first conversion module and the second conversion module are arranged, so that the frequency response sensitivity of the electronic equipment to the audio signal can be improved, and the sound quality output by the electronic equipment is improved.
In some embodiments, the length of the second channel is less than the length of the first channel.
Illustratively, the frequency of the second acoustic signal is greater than the frequency of the first acoustic signal. Therefore, the increase in the length of the sound guiding channel has a stronger attenuation effect on the second acoustic signal than on the first acoustic signal. In order to ensure the quality of the second acoustic signal, the second sub-conversion module is arranged in the area close to the sound outlet hole, so that the length of the second channel is smaller than that of the first channel.
This embodiment sets up the length through with the second passageway into being less than the length of first passageway, is favorable to reducing when taking up electronic equipment inner space, improves the quality of second acoustic signal, and then improves the sound quality of electronic equipment output.
