[0002] A loudspeaker is a device that converts electrical signals into sound, commonly used in audio playback systems. It receives electrical current signals from the audio source, drives the internal vibrating diaphragm (diaphragm) to produce mechanical vibration, and forms sound waves in the air, which are finally heard by the human ear. When the audio signal passes through the voice coil in the loudspeaker, the current change produces a changing magnetic field, which interacts with the fixed magnetic field of the magnet, pushing the voice coil and the diaphragm to vibrate, thereby producing sound waves.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, a loudspeaker with receiver function according to this utility model includes a bracket 1, a voice coil 2, a dome 3, a front cover 4, a circuit board 5, a pole piece 6, a magnet 7, and a magnetic cup 8.

[0032] The two leads on the voice coil 2 are respectively soldered to corresponding positions on the circuit board 5 to achieve electrical connection;

[0033] The circuit board 5 is bonded to one side of the bottom of the bracket 1;

[0034] The lower surface of the dome 3 is bonded to the top of the voice coil 2, and the upper surface of the dome 3 is bonded to the diaphragm 9, which is bonded to the bracket 1.

[0035] The front cover 4 is bonded to the top of the bracket 1, and a plurality of first sound holes 10 are evenly distributed on the front cover 4.

[0036] The magnetic bowl 8 is bonded to the lower surface of the bracket 1;

[0037] The bottom of the magnetic cup 8 is provided with second sound holes 11 on both sides; the bottom of the magnet 7 is bonded to the inside of the magnetic cup 8; the pole piece 6 is bonded to the top of the magnet 7; the magnet 7 and the pole piece 6 are located inside the voice coil 2.

[0038] like Figure 6 As shown, when an audio current passes through the voice coil, according to Ampere's law, a current-carrying conductor in a magnetic field experiences a force. Since the voice coil 2 is located in the magnetic field of the permanent magnet, it experiences a force related to the magnitude and direction of the current. The audio current is an alternating current that changes with time, so the magnitude and direction of the force on the voice coil 2 also change over time. Under this force, the voice coil 2 reciprocates within the magnetic field of the permanent magnet. This motion is transmitted to the diaphragm 9 through the dome, causing the diaphragm 9 to also reciprocate. The vibration of the diaphragm 9 causes the surrounding air to vibrate, thus generating sound waves, which we can hear. Audio currents of different frequencies and amplitudes cause the voice coil to vibrate at different frequencies and amplitudes. Simultaneously, the vibrating plate at the bottom of the voice coil 2 allows for linear vibration under high voltage, enabling the product to withstand higher power. This, in turn, allows the diaphragm 9 to emit sounds of different pitches and loudnesses, thus achieving the conversion from electrical signals to sound signals.

[0039] In this embodiment, both the first sound outlet 10 and the second sound outlet 11 are covered with a mesh 12, which effectively prevents external dust from entering the bracket 1.

[0040] In this embodiment, as Figure 3As shown, the corner of the support 1 is provided with a positioning protrusion 13. Figure 4 As shown, the corner of the support 1 is provided with a positioning protrusion 13.

[0041] In the embodiment, the bottom of the support 1 is bonded with a balance plate 15 opposite to the other side of the circuit board, which ensures the balance of the bottom of the voice coil 2 and further ensures the sound effect.

[0042] In the embodiment, as shown, Figure 5 As shown, the bottom inner wall of the magnetic bowl 8 is provided with a positioning protrusion plate 16, and the second sound hole 11 is located outside the positioning protrusion plate 16, which realizes the quick positioning and installation of the magnetic steel 7 without affecting the sound effect.

[0043] In the embodiment, the bottom edge of the support 1 is provided with a profiling area 17, which is matched with the edge shape of the magnetic bowl 8, thereby realizing the quick and accurate installation of the magnetic bowl 8.

[0044] The above has specifically described the preferred embodiment of the utility model, but the utility model is not limited to the embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims.
